Copy linkEnterprise HR and HCM software for UK organisations with 1,000+ employees: a buyer’s guide
Updated 4th September 2026 | 24 min read Published 2nd September 2026
For organisations of 1,000+ employees, choosing the right enterprise HCM system can make or break your HR processes; buyers at this scale typically prioritise:
- How the platform fits their existing technology stack
- The depth of its native UK payroll functionality
- How well it supports UK compliance obligations
- How long implementation takes
- System cost
This guide covers each of these points and how our HR software, IRIS Cascade, addresses the requirements.
At enterprise scale, HR software is usually described as HCM, or human capital management. The main distinction from a conventional HR system is that HCM covers a wider scope, such as core HR, payroll, talent management and workforce analytics, all in a single platform. This guide uses both terms.
Key takeaways
- An HCM platform is an infrastructure decision because at 1,000+ employees, you’re selecting a system that will hold employee data, run payroll, produce workforce reporting and support financial planning.
- Map your integration requirements before you shortlist because your existing technology ecosystem needs to connect with your enterprise HCM platform.
- Implementation for enterprise HCM platforms commonly runs six to nine months, so timeline and delivery approach deserve as much scrutiny as functionality.
- At 1,000+ employees, the compliance load is less about new obligations than about volume and spread. Gender pay gap reporting and equality action plans apply from 250 employees, and collective consultation can be triggered by 20 redundancies at a single site, which a multi-site employer has to track across every location.
- The per-employee rate is only part of the cost. Model the total cost over three years, covering implementation, integration, training and support, and establish which items are included in the quoted rate and which are added on top.

Frequently asked questions (FAQs)
Why is HR software selection different at 1,000+ employees?
At 1,000+ employees, the HR software you select is an infrastructure decision.
Rather than buying a system purely for the HR team, you’re committing the entire organisation to a platform that:
- Manages the employee lifecycle
- Supports employee engagement
- Holds employee data
- Runs payroll
- Feeds board-level workforce reporting
- Supports financial planning
These factors change how the selection decision is made, how long it takes to decide on an HCM platform and who is required to sign it off.
What changes in the enterprise buying process?
In a smaller business, the HR manager can shortlist a few vendors, run through demos and make their recommendation.
However, at a 1,000+ employee business, the buying process typically involves:
- A formal Request for Proposal (RFP) with evaluation criteria
- HR defining requirements, with other teams and stakeholders being brought in for commercial negotiation
- IT security and architecture review
- Finance sign-off against the cost model
- Legal review of contract terms, service levels and exit provisions
- Executive or board sponsorship, usually with a named owner
Expect six to nine months from requirements gathering to go-live.
What changes structurally at enterprise scale?
An enterprise organisation isn’t simply a small business with more employees, so what you need from your HR software differs too.
- Multiple companies under one group: acquisitions, subsidiaries and joint ventures each bring their own PAYE reference, contracts and terms.
- Complex reporting structures: during their time at your organisation, a single employee can have multiple managers, work across different teams and move departments more than once, which your HCM system has to capture.
- HR run locally: individual sites manage their own HR day-to-day while following your central policy, so the system needs to give local teams control without central HR losing sight of what’s happening.
- Large temporary workforce: contractors, agency workers and people employed through umbrella companies all bring tax and status requirements that don’t apply to your permanent staff.
- Overseas employees: UK-headquartered organisations at this size usually also have staff outside the UK.
- Board-level scrutiny: executive teams expect headcount costs, staff turnover and pay gap figures.
Which HCM platform fits your enterprise technology ecosystem?
For most enterprise organisations, their existing technology ecosystem will narrow the shortlist of potential HCM platforms.
There’s a massive requirement for HR to work together with other areas of the business, and the success of this fundamentally comes down to the software integration capabilities on offer.
Get it wrong, and it’s expensive and difficult to reverse.
| Systems HCM connects to | Why the connection matters | What to check |
| Finance | Your finance team needs accurate staff costs by department, budget and entity. Without live data feeding directly into finance, headcount cost reporting becomes a manual job that rarely matches the truth. | How salary, pension and employer National Insurance costs map to your budget structure, and whether the connection runs automatically or via an export. |
| Payroll | Changes in HR mean changes in payroll. If HR and payroll are disconnected, each new starter, leaver, pay rise and absence has to be entered twice. | Whether payroll sits on the same platform or connects to it. |
| Recruitment | A new candidate’s data should automatically become employee data without anyone retyping it. Hiring metrics also need to be accurately captured for reporting. | Whether the platform includes recruitment or connects to your existing system, and how data is shared. |
| Time and attendance | Shift patterns and overtime can vary greatly in a 1,000+ employee business. Getting these hours into payroll accurately is a must; otherwise, due to the volume, you risk frequent errors. | How approved hours reach payroll, and whether the platform supports workforce planning. |
| Learning and development | You need to evidence that mandatory training is complete. This becomes particularly important for regulated roles and harassment prevention duties. | Whether training records sit in the HR platform or a separate system, and how completion is reported. |
| Benefits and pensions | Multiple pension providers and benefit schemes each need accurate data and enrolment without manual checks. | How the platform sends data to each provider, and whether it supports the number of schemes you offer. |
Start with your ERP and finance system
What finance or ERP system you use is typically the first thing that narrows the HCM shortlist, because workforce data must reach it cleanly.
Payroll costs need to land in the general ledger against the right cost centres, and headcount needs to feed budgeting.
This all needs to happen without someone rebuilding a spreadsheet every month.
Most UK enterprise organisations fall into one of four positions:
| Your existing stack | What it usually means for your shortlist |
| SAP-led finance | The same-vendor route offers the deepest native integration, but only justifies itself if you need global HR and payroll at scale. If your workforce is primarily UK-based, you are paying for reach you will not use. |
| Oracle-led finance | Tight integration with Oracle financials is the main advantage, weighed against implementation length and the consulting resource required. |
| Microsoft-centric | Fewer organisations run a full Microsoft HR stack, so this usually becomes a question of how well a platform integrates with Entra ID for single sign-on, and with Power BI or your reporting layer. |
| ERP-agnostic, mixed or legacy on-premise | The largest group in the UK mid to upper market, and the one with the most genuine choice. Selection here is driven by UK payroll depth, compliance and implementation speed rather than by vendor alignment. |
If you sit in the fourth group, do not default to a global suite because it is the most recognised name.
UK-native platforms typically deploy faster, are built around UK employment law rather than adapted to it and do not require a global implementation partner.
What do UK enterprise organisations need from an HCM platform?
For those organisations with 1,000+ employees, use these criteria as a scoring framework when assessing HCM platforms.
| Enterprise HCM criteria | Why it matters at 1,000+ employees |
| Payroll depth | Payroll for an enterprise organisation has a lot of moving parts: – Complex pay structures – Shift patterns – Commission – Variable pay – Multiple pay frequencies – Full-time and part-time workers – Temporary workers At this scale, there’s no room for manual correction. Note: the software should also be HMRC-recognised. |
| Statutory rates and pensions | Large workforces often mean several pension providers, defined benefit schemes and complex contribution rules. Assessment, re-enrolment and reporting all need to run without manual intervention at this volume. Additionally, all statutory changes, whether that’s updates to Statutory Sick Pay or the National Minimum Wage, need to be applied automatically. Manual management at scale is time-consuming and prone to error. |
| Multi-site structures | Separate legal entities, cost centres and reporting lines need to coexist in one system that offers clear visibility. |
| Global capabilities | Many UK-headquartered organisations at this size employ staff overseas. Establish whether you need full payroll in each country or centralised records with local payroll handled separately. The two requirements lead to very different platforms and very different costs. |
| Workforce analytics | The ability to offer board-level reports, headcount cost modelling, scenario planning and pay gap analysis depends on trustworthy data. |
| Talent management | You need to manage performance, succession planning and career pathing for thousands of people with hundreds of managers. |
| Implementation | At this scale, your organisation will likely have its own bespoke requirements which your implementation must support. Deployment length, partner requirements and internal resource commitment vary enormously between HCM platforms. |
| Total cost of ownership | A per-employee rate rarely represents the full cost. Vendors draw the line between ‘included’ and ‘extra’ in very different places, which could include: – Implementation – Data migration – Integration work – Training – Ongoing support – Separately priced modules Compare total three-year cost on like-for-like scope rather than comparing rates. |
| Integration | Integration with your essential business systems needs to be supported, plus an open API for anything bespoke. |
| Security and data governance | Meeting UK GDPR obligations at enterprise scale means your platform has to support: – Role-based access, so each user sees only the records their role requires – Audit trails covering who viewed or changed what, and when – Defined retention rules that delete employee data at the end of its retention period – Clarity on where your data is held and which sub-processors can access it Expect IT to also ask for ISO 27001 as a minimum, and often Cyber Essentials Plus. |
| Customer support | If challenges arise, having a named account manager, contractual response times and access to support resources help ensure a speedy resolution. |
| Scalability | The platform has to handle further growth and absorb acquisitions; otherwise, you risk needing a new platform further down the line. |
How does IRIS Cascade address enterprise requirements?
IRIS Cascade is an all-in-one enterprise HR and payroll platform from IRIS Software Group.
Here’s how IRIS Cascade maps against the above points.
| Enterprise HCM criteria | How IRIS Cascade addresses it |
| Payroll depth | IRIS Cascade has a built-in payroll module that is HMRC-recognised. With payroll sitting on the same platform as HR, elements like maternity records in HR automatically become maternity pay in payroll. IRIS Cascade can also integrate with third-party payroll software, should you wish to keep an existing system. |
| Statutory rates and pensions | Legislative updates are applied automatically as part of your subscription, covering annual rates and changes. Auto-enrolment assessment and reporting also run within payroll across multiple schemes and providers, if required. |
| Multi-site structures | IRIS Cascade offers configurable organisation structures, supporting: – Multiple legal entities – Cost centres – Hierarchies Role-based access controls also let localised HR teams manage their own unit while central HR maintains full visibility. |
| Global capabilities | IRIS Cascade holds records for your whole workforce, including employees based outside the UK, with native payroll processing for the UK. For overseas payroll, IRIS Global provides a managed service covering 135 countries, using in-country specialists to handle local tax, compliance and filing, with payments in 127 currencies. This runs alongside IRIS Cascade rather than inside it, so you get UK payroll depth without paying for global payroll modules you don’t need. For multilingual workforces, LinguaSkin adds switchable language packs to IRIS Cascade self-service, with no changes required to the system itself. Employees interact in their preferred language while your HR team continues to administer the system in English. |
| Workforce analytics | Over 50 standard reports are available in the platform, including: – Headcount – Turnover – Salary progression – Absence – Gender pay gap Bespoke reporting for organisation-specific analysis is also available. Additionally, real-time dashboards give you and the wider business insights into day-to-day data areas. |
| Talent management | IRIS Cascade’s performance management supports appraisals, objective-setting and progress tracking, linking them back to business goals. The learning and development module also manages internal and third-party courses, and tracks completion across the organisation. |
| Implementation | IRIS Cascade implementation includes: – Structured implementation plans with dedicated consultants – Data import support – Tailored training – Ongoing support |
| Total cost of ownership | IRIS Cascade is priced per employee per year, with support and cloud hosting included in the rate. The IRIS Cascade rate reduces as headcount rises. Additionally, legislative updates are covered by your subscription rather than charged as upgrade projects. Implementation is quoted separately against your requirements. There are also optional ongoing service packages which add an annual review with a consultant, ensuring the platform continues to be optimised after go-live rather than left as delivered. |
| Integration | Pre-built connectors cover key areas, such as: – Finance – Payroll – Learning – Recruitment An open API is also available for custom integrations. Additionally, the IRIS HR Marketplace provides industry-leading partners you can add to IRIS Cascade. |
| Security and data governance | IRIS Cascade holds ISO 27001 and Cyber Essentials certifications for information security, alongside ISO 9001 for quality management, giving you confidence that your sensitive people data is protected to the highest standards. The IRIS Cascade system also features: – Single sign-on – Multi-factor authentication – Role-based access controls – Full audit trails |
| Customer support | UK-based support with named account managers in addition to: – Consultancy services – Training – System health checks – Support resources |
| Scalability | As you grow or acquire new businesses, IRIS Cascade adapts, offering a modular approach so you can scale the system as needed. |
UK compliance obligations for enterprise organisations
Compliance becomes substantially more complex at 1,000+ employees.
More staff, more nuance, more complexity.
Each compliance area has a direct implication for what your HCM system needs to handle.
Common enterprise compliance areas are as follows.
Redundancy and collective consultation
Collective consultation is triggered by 20 or more redundancies at one establishment within 90 days, with a minimum of 30 days’ consultation, rising to 45 days for 100 or more.
The financial exposure has also doubled.
Since 6 April 2026, the maximum protective award is 180 days’ pay per affected employee, up from 90.
A second change is also coming, which matters if you operate across multiple sites.
The Employment Rights Act introduces an organisation-wide trigger that aggregates redundancies across locations, expected during 2027.
Off-payroll working (IR35)
Every organisation at this size is responsible for determining the employment status of contractors working through their own companies, and for issuing Status Determination Statements.
Pay gap reporting and pay transparency
Gender pay gap reporting applies to employers with 250 or more employees.
Additionally, action plans setting out how you’ll close the gap and support employees through menopause are voluntary now but becoming mandatory in 2027.
Incorrect wages
Payroll errors are rarely confined to a single payslip for enterprise organisations.
A misconfigured rule or wrong National Insurance category repeats across thousands of people, every pay run, until someone spots it.
Underpayment is an expensive mistake.
National Minimum Wage arrears carry penalties of up to 200% and public naming and shaming, in addition to opening you up to assessment from the Fair Work Agency.
Multi-country organisations
Different countries bring different contractual terms, leave entitlements and tax rules.
You must ensure your processes are compliant with the rules in that specific country.
Managing this in separate local systems limits your view.
Employee data
HR holds the most sensitive data in the business, from bank details and home addresses to health information and disciplinary files.
You can’t risk this data getting into the wrong hands.
What’s more, the UK is governed by strict data protection legislation, such as UK GDPR, the Data Protection Act and the newer Data (Use and Access) Act.
Non-compliance can mean fines of up to £17.5 million or 4% of worldwide turnover.
However, it’s not just malicious actors you need to worry about, as everyday human error can also put you at risk.
Employment Rights Act 2025
The Employment Rights Act has created major disruption in UK compliance, using a phased approach which means businesses have to keep up with regular change.
For example, the recent April 2026 changes have already introduced day-one rights to paternity leave and Statutory Sick Pay (SSP) from the first day of sickness, as well as launching a new Fair Work Agency (FWA).
More changes are coming later this year and in 2027, including unfair dismissal protection changing to six months’ service, in addition to restrictions on fire-and-rehire practices.
Across all of these, your HR policies and processes all have to move with the changing legislation.
This section is a summary of current UK requirements, not legal advice. Every effort has been made to ensure the content is accurate at the time of writing, but details are subject to change. If you require legal advice, please consult a qualified professional.
What does enterprise HCM implementation look like?
Implementation deserves as much scrutiny as the software’s functionality.
Typically, for an organisation of 1,000+ employees, a full HCM implementation takes six to nine months.
The biggest implementation variables are:
- How many separate sites you run
- How clean your existing data is
- How many integrations you need
We recommend you ask every vendor for a timeline based on your specific setup.
It’s also worth asking for references from organisations of similar size who have gone through the implementation to check that it holds.
Who needs to be involved in an HCM platform implementation?
- Project manager: usually someone from HR or IT who runs the project day-to-day, keeps the internal teams to deadlines and is the single point of contact for your vendor.
- HR: decides how the system works, holiday/sickness rules, who approves what, and which policies the system needs to apply automatically.
- Payroll: confirms every type of payment and deduction is set up correctly, from basic pay to overtime, bonuses and pension schemes.
- IT: connects the new system to the ones you already use, sets up how people log in and checks security before anything goes live.
- Finance: makes sure staff costs come out of the system in the format their budgets and reporting need.
- Line managers: test the parts they’ll use, such as approving holiday and viewing their team.
How IRIS Cascade approaches enterprise implementation
Changing HR software is a significant decision.
We often hear concerns about the move to new software, the time to implement and what happens in the meantime.
That’s why we’ve designed our implementation process to be as smooth and stress-free as possible, removing the typical barriers of data migration, training and set-up.
Our IRIS Flexiserve packages offer a range of implementation options to suit the unique needs of your business.
A typical IRIS Cascade implementation includes:
1) Planning
We’ll work with you to outline a clear project plan and success criteria.
2) Execution
We configure IRIS Cascade to match your specific requirements and migrate your data.
3) Training
Our training videos or 1:1 training help bring your team up to speed.
4) Deployment
We guide you through the rollout, with online resources and support from our experienced team.
5) Review
We work with you to ensure your project meets your expectations and you’re set up for success.
What is the total cost of ownership of enterprise HCM?
The total cost of two HR systems quoted at a similar per-employee rate can massively differ over three years, because the rate is only one part of the pricing.
When building your cost model, consider these five areas:
- Software licence
- Implementation
- Integration
- Training
- Ongoing support
Establish which of these sits inside each vendor’s quoted cost, as it tends to vary more than buyers expect.
The hidden cost drivers of enterprise HCM software
- Support and hosting: some vendors include these in the total cost while others charge them as a percentage of the software cost, which scales with headcount.
- Modules priced individually: functionality you assumed was included as standard – whether that’s expenses, timesheets or training records – may be classified as chargeable add-ons.
- Implementation and data migration: usually the largest one-off cost in year one, and the hardest to quote accurately up front.
- Integration: pre-built connectors tend not to cost extra, but anything bespoke that requires development and ongoing maintenance will likely be charged.
- Legislative updates: determine whether statutory changes are covered by your subscription or delivered as chargeable upgrade projects.
- Your time: budget for the internal resource the implementation will demand across HR, payroll, IT and finance is rarely counted and consistently underestimated.
- Non-standard requirements: at 1,000+ employees, your requirements probably aren’t standard – multiple PAYE references, several pension providers and locally run HR tend to sit outside a typical package, so get them scoped and priced before you sign.
- Uplifts and exit: check how the rate moves at renewal, what happens if headcount reduces and the costs to extract your data at contract end.
How do you run an enterprise HCM platform evaluation?
A formal, scored evaluation is the best way to assess a platform and can greatly impact the information you get from vendors.
When it comes to gathering your requirements, bring in the right stakeholders:
- HR on the employee lifecycle, policy, absence, performance and reporting needs
- Payroll on pay structures, frequencies, pension schemes and RTI
- IT on security, integration architecture, single sign-on and data residency
- Finance on cost centre structure, general ledger mapping and workforce cost reporting
- Procurement and legal on commercial terms, SLAs and exit provisions
- The executive sponsor on what the platform needs to deliver at board level
Top tip: separate requirements into must-have, should-have and nice-to-have.
What to score, and how to weigh it
Check the platform against what matters to your organisation.
A recommended starting point includes:
- Compliance capability
- Core HR and payroll functionality
- Self-service
- Software integration
- Implementation approach and timeline
- Security and data governance
- Total cost of ownership
- Customer support
Top tip: ask for scenario-based responses rather than feature checklists.
HCM due diligence questions for a 1,000+ employee organisation
Take these questions into every enterprise HCM evaluation:
- Can you show us how the system handles our organisation structure?
- How granular can access permissions get?
- Can you show us an employee’s first two weeks in the system?
- How does the system handle absence and holidays?
- Can you produce headcount and staff cost reports?
- How can you evidence that a fair process was followed if a dismissal or grievance is challenged?
- How quickly are legislative changes applied?
- What does your payroll functionality look like?
- What’s a realistic implementation timeline for our organisation?
- What’s the full three-year cost, including implementation, integration and support?
- Which parts of the system are included as standard and which are priced separately?
- What does your support agreement cover?
- Is an account manager assigned to us?
- Where is employee data held, and who can access it?
- Can you provide references from similar organisations?
- What happens at contract exit, and how is our data returned?
Why do enterprise organisations choose IRIS Cascade?
- Streamline complex processes: IRIS Cascade automates intricate HR processes, such as absence management, holiday scheduling and onboarding workflows. KP Snacks reduced HR and payroll administration costs by up to £25,000 a year after moving to IRIS Cascade, without adding headcount.
- Work from anywhere, effortlessly: with an intuitive interface and cloud functionality, IRIS Cascade empowers your HR team to manage tasks securely and efficiently, no matter where they are.
- Data-driven decision-making: real-time dashboards and advanced reporting transform your HR data into actionable insights, enabling faster, smarter decisions. Spurgeons cut monthly reporting from five and a half days to two using automated reports and scheduled dashboards.
- Stay ahead of compliance: automatic updates within the IRIS Cascade system ensure your organisation remains compliant with evolving workplace regulations, minimising risk and safeguarding your processes.
- Enterprise-grade security and reliability: protect your sensitive workforce data with advanced security measures and robust system reliability.
- Seamless system integration: integrate IRIS Cascade with other essential systems, connecting key processes and enhancing data accuracy.
IRIS Cascade: a UK-native platform, built for UK employment law
Most enterprise HCM platforms marketed in the UK are designed for global workforces, adapting to UK requirements afterwards.
IRIS Cascade was built the other way round.
UK employment law, HMRC payroll obligations and statutory frameworks are the foundation of IRIS Cascade, not just a layer sitting on top of it.
This difference shows up in four places:
- Compliance is an automatic an update, not a project: legislative changes are applied automatically as part of your IRIS Cascade subscription. For example, when Statutory Sick Pay became payable from day one in April 2026, IRIS Cascade was updated and ready from day one. With IRIS Cascade, you’re not scoping a large update project or waiting for a global release to reach the UK.
- Implementation runs in six to nine months, not eighteen: scoping, configuration and data migration are handled by IRIS teams here, not by a third-party partner or an offshore delivery centre. Ask us for a timeline against your own site count, data quality and integration list.
- Support is UK-based: with IRIS Cascade, UK businesses get a named account manager and contractual response times from a team working in your time zone, under your regulatory environment.
- Employee data stays in the UK: IRIS Cascade holds ISO 27001 and Cyber Essentials certification, with UK data residency and role-based access controls as standard.
What IRIS Cascade customers say
“When we implemented Cascade, my goal was to make our HR processes as paperless as possible. We took the time to personalise the system to fit our needs, and that effort has truly paid off. For instance, we set up a query for our journals – previously, we had to manually create over 60 journals across our numerous sites. Customising the system required time and effort, but now we’re reaping the benefits.”
Sarah Waddington, Head of HR, Stoneacre
“We are so happy with IRIS Cascade – the software is fantastic, the team at IRIS has gone above and beyond to support us and we’re already seeing the benefits of having an integrated system in place. I would highly recommend it, especially to those still using multiple systems!”
Neil Caddle, HR Advisor at Nixon Hire
“Our previous HR system relied heavily on numerous bolt-ons to cover the entire employee lifecycle, which made it cumbersome and inefficient. With everything integrated into Cascade, we’ve streamlined our processes significantly, enabling us to enhance the experience for our employees.”
Sallyann Gretton, HR Specialist, Futures Housing Group
“We used another HR system previously and we weren’t able to make the same level of changes that we can on Cascade. We’re now able to make tweaks to our workflows and, as we are evolving, have the power to create new workflows or amend them. To have a piece of software where we can actually fix our own problems or get very quick support from IRIS is a massive positive.”
Vikki Chesterman, HR Systems Tech Analyst, Aquest

Frequently asked questions (FAQs)
Which enterprise HR or HCM platform is best for a UK organisation with 1,000+ employees?
There’s no single answer, as the right platform depends on your organisation.
You need a platform that handles your specific requirements, whether that’s multiple sites, complex reporting structures, compliance pressure or connecting to the systems you already have.
IRIS Cascade is a UK-native HR platform built for enterprise organisations, offering a wide range of industry-leading features.
How long does implementation take at this size?
For an organisation of 1,000+ employees, expect around six to nine months from kick-off to go-live.
The complexity of your organisation will impact this timeframe.
Ask every vendor for a timeline based on your own setup.
Who needs to be involved in an HCM implementation?
More people than many organisations initially think.
You’ll need:
– Project manager
– HR
– Payroll
– IT
– Finance
– Line managers
What does enterprise HR software cost for 1,000+ employees?
There’s no single figure at this scale, because cost depends on which modules you need, your headcount and how complex implementation is.
Rather than comparing per-employee pricing, ask each vendor for a three-year total covering:
– Licence
– Implementation
– Integration
– Training
– Support
Support, hosting, legislative updates and individual modules are included by some vendors and charged separately by others.
IRIS Cascade is priced per employee per year with support and cloud hosting included in that rate, and implementation is quoted against your specific requirements.
How does an HR platform support UK compliance at this scale?
It applies legislative changes automatically, so rate changes and calculation rules are handled for you.
Your team still has to make the policy and process changes a reform like the Employment Rights Act brings, but they’re not also rebuilding the system to match.
Ask vendors how quickly updates are implemented and who bears the cost.
Do we need HR and payroll on the same platform?
Not necessarily, but they do need to be properly connected.
When HR and payroll are separate, every change is entered twice, and errors creep in.
IRIS Cascade runs HR and payroll together, offering an all-in-one platform.
If you’re keeping an existing payroll provider, IRIS Cascade also has pre-built connectors and an open API.
