When spreadsheets stop working for HR: the signs and what to replace them with

If your HR admin has outgrown spreadsheets, it may be time to implement a human resources information system (HRIS), also known as HR software.

An HRIS offers a dedicated system for managing your people, creating a single record for each employee which can map against your HR processes.

Many businesses start with managing their HR processes through spreadsheets, but it’s not a permanent solution.

IRIS research, which surveyed 300 HR professionals,  found that 34% of respondents are running HR on a patchwork of systems and spreadsheets, with a further 24% using purely manual processes.

If you’re not sure whether it’s time to move to an HRIS, the first step is determining whether your spreadsheets have stopped coping.

This blog covers how to recognise that point, what the risks are if you continue to use spreadsheets and what an HRIS will and won’t fix.

Ten signs that it’s time to stop using spreadsheets for HR

Most businesses don’t suddenly decide they’ve outgrown spreadsheets and it’s time to move to an HRIS.

Instead, they notice inefficiencies and errors creep into day-to-day processes, compounding over time until the issue is big enough to prompt action.

If several of these points look familiar, you’ve probably outgrown spreadsheets.

1. There’s more than one version of the holiday tracker: managers begin keeping a copy of the holiday tracker on their desktop, meaning you lose visibility of what’s happening around the business.
2. You’re the only person who knows how the file works: the formulas, hidden columns and the accrual logic sit with you rather than with the business, creating issues if you’re ever away from work.
3. Employees ask you rather than looking it up: whether it’s staff wanting to book holidays or find a payslip, each of these time-consuming questions exists only because the answer is not available to them.
4. A leaver’s final holiday balance takes more than a few minutes to establish: cross-checking two files and a run of emails to work out what someone is owed is a sign of poor record-keeping.
5. You cannot say who changed a detail, or when: due to the sensitive nature of HR data, you need strict record-keeping, so you need visibility of who changes what and when, as well as the option to reverse changes if they turn out to be errors.
6. Right to work expiry dates are not prompting anyone: while expiration dates for time-limited visas and permissions are recorded in your spreadsheets, nothing flags critical deadlines to HR or management before the rights actually expire.
7. Absence data is re-typed into payroll each month: the same information is entered twice, which is where most avoidable payroll errors happen.
8. Subject access requests mean searching multiple files: when HR data is spread across different spreadsheets and inboxes, it becomes extremely difficult to find everything you hold about one person.
9. Reporting for the board is done by hand: to get insights, you need to manually find and compile headcount, turnover and absence data.
10. Employee details are entered more than once: one person’s information is manually keyed into HR, payroll and often a third place, such as a learning management system.

Several of these points surface around particular moments in the employee lifecycle. Our guide to the employee lifecycle works through each stage, covering the HR admin that attaches to it.

What actually goes wrong when HR uses spreadsheets

There are five key areas where, if you continue to use spreadsheets when they’re no longer fit for purpose, you’ll see consequences, each getting worse as time goes on.

Disconnected records create HR and payroll errors

When two files disagree, someone has to decide which is right, usually under time pressure and without evidence.

In these scenarios, mistakes often compound because each edit and correction creates another version of the file.

Every version is another chance for the wrong figures to reach payroll or a manager.

You’re unable to evidence decisions

Spreadsheets store the current figures, not the history.

For payroll, absence and performance, that nuance is the difference between a defensible decision and an assertion, should it be taken to a tribunal.

If someone questions a holiday balance, sickness trigger or probation outcome, you can describe what you believe happened, but you can’t evidence it.

Employee queries eat up your time

Every routine employee question, whether it’s about booking a holiday or locating a payslip, becomes a task for HR.

Individually, these requests may only take a few minutes.

However, collectively they add up and eat away at a large portion of your time.

The same IRIS research found HR professionals lose an average of 3.4 hours a week to poorly integrated systems, and 72% said inefficient systems stop them from doing strategic or people-focused work.

Our guide to addressing HR burnout covers what that sustained admin load does to the person carrying it and what can be done to minimise the burden.

A single point of failure

When one person holds all the logic, the business becomes dependent on their availability.

As your business grows, the number of requests, changes and obligations exceeds what one person can manage with a spreadsheet.

Compliance risk

Spreadsheets break no specific compliance rule.

However, they do make several obligations far harder to meet, and considerably more challenging to evidence.

• Right to work: evidence must be kept for the duration of employment plus two years, and time-limited checks need re-verifying before they expire. See GOV.UK guidance on right to work checks.
• Holiday pay records: under regulation 16B of the Working Time Regulations 1998, in force from 6 April 2026, records must be kept for six years from the date each was made.
• Absence and Statutory Sick Pay (SSP): SSP is calculated from absence data, so the accuracy of the record sets the accuracy of the payment.
• Subject access requests: if a subject access request arrives, can you carry out a reasonable and proportionate search of everything you hold about the person, and produce it within the statutory deadline? The ICO’s guidance on keeping employment records sets out what that involves, and our guide to HR data security and UK GDPR standards covers the wider data protection picture.

2027 unfair dismissal changes

From 1 January 2027, the unfair dismissal qualifying period drops from two years to six months under section 25 of the Employment Rights Act 2025.

As such, documented performance and probation records will play a much greater role far earlier in employment.

Our guide to UK employment law updates for 2026 provides more detail on what’s expected and how to prepare.

Now, to be clear, keeping HR records in spreadsheets is not unlawful, and the obligations are the same either way.

Your obligations are simply harder to satisfy and prove when the record sits across several files.

What an HRIS replaces

Mapped against the above points, an HRIS gives you:

• One employee record that HR, payroll, managers and reporting all work from, meaning there are no additional copies of your data to reconcile.
• Employee self-service for holiday requests, balances, personal detail updates and documents, enabling staff to handle basic routine questions themselves.
• Manager approval without HR in the middle, with requests routing to the right person instead of sitting in an inbox and automated prompts to ensure things don’t stall.
• Absence and entitlement calculated rather than maintained, including accrual for irregular hours and part-year workers.
• An audit trail, covering who changed what and when.
• Expiry dates that prompt HR and managers, so things like right-to-work re-verification and probation reviews are flagged before the deadline.
• Real-time data, which can be easily pulled from the system through pre-built and custom reports, as well as being accessible through dashboards.

The honest way to frame this is that an HRIS doesn’t do anything a determined person with a spreadsheet and enough time couldn’t do.

However, the defining factor to draw your attention to is ‘time’.

As your business grows, so does everything HR has to manage, meaning spreadsheets aren’t sustainable, especially if you want everything correct and error-free.

Our blog on supporting the employee lifecycle helps show the role an HRIS plays across onboarding, absence and leavers.

If you want a practical test to judge whether an HR system genuinely holds one employee record, count how many places a new starter has to be entered.

What moving to an HRIS will not fix

An HRIS will give you the foundations to run HR, but the onus is still on you.

For example:

• An HR system will not create a policy you never defined. However, if your approach has always been decided case-by-case, the system will ask you to define it, and you will have to.
• An HR system won’t make managers approve things promptly. But it will make the delay visible and send reminders, which helps.
• An HR system can’t clean up data that was already wrong in the spreadsheets. This is why migration is the point at which most businesses finally audit the data they hold, and why that audit takes longer than expected.

Where to start

When looking for an HRIS, start by defining your statutory obligations and what you need the system to support.

For example, areas such as onboarding, absence and leavers can be common pain points when managed via spreadsheets.

These three areas generate records you need to produce if anyone asked, and they’re where a spreadsheet’s weakness costs the most.

Additionally, before moving to an HRIS, it’s worth establishing what data you hold and where.

Most businesses find employee data in more places than they expected, such as a main spreadsheet, shared drive of documents, payroll system and inboxes.

Bringing in an HRIS offers a fresh starting point, so use it as an opportunity to clean your data rather than moving it across as is.

For what to look for in a system at this size, our buyer’s guide to HR software for UK businesses with 50 to 200 employees sets out the requirements and the questions to ask vendors.

How IRIS fits

For businesses looking to move away from spreadsheets, Staffology HR is the route we recommend.

Staffology HR connects all your HR data, offering one employee record and key HR processes, such as absence, holiday and onboarding, run as workflows rather than checklists.

It also provides self-service through a browser or mobile app, enabling employees to:

• Check leave balances
• Request time off
• Update their own details
• Retrieve documents such as P60s and contracts

Additionally, Staffology HR updates automatically as UK regulations change, and provides over 50 standard reports which cover balances, absence, sickness, holiday and documents.

For those looking for HR and payroll, Staffology HR integrates with payroll systems, such as Staffology Payroll, so absence, overtime and expenses reach the pay run without being re-keyed.

For businesses with more complex HR requirements, multiple sites or configurable workflows that differ by team, IRIS Cascade is the best choice, offering greater customisation and payroll built into the platform rather than integrated.

HR and spreadsheets

Frequently asked questions (FAQs)

What should we replace HR spreadsheets with?

Replace spreadsheets with a human resources information system (HRIS), also known as HR software. An HRIS holds one record per employee, covering personal details, contracts, absence and documents. It also gives employees and managers self-service access.

When should a business stop using spreadsheets for HR?

Businesses should stop using spreadsheets for HR when the admin and errors increase. In practice, that is usually somewhere between 50 and 200 employees. This can be even earlier if you have multiple sites, high turnover or statutory records that are difficult to produce on request.

What is an HRIS?

An HRIS is a system that holds employee data as one record and manages the processes attached to it, including absence, onboarding, leavers and reporting. Unlike a spreadsheet, it records history and changes as well as current values.

Is it legal to keep HR records in spreadsheets?

Yes, you can keep HR records in spreadsheets. There’s no legislation that requires specific software. However, while the obligations are the same either way, they’re far harder to maintain and evidence when data sits across several files.

How do you move HR data from spreadsheets into a new system?

To move from spreadsheets to an HR system, start by auditing your data and then clean it rather than migrating it as it stands. Most providers support structured import at setup, so confirm the required format before you begin.
