Switch to IRIS


10 reasons to switch to IRIS today

There is something your software provider doesn’t want you to know – and for a good reason.

They fear once you have gained this knowledge, you’ll be heading for the exit door and coming our way instead.

So, why is your current supplier worrying you will find out about IRIS accountancy software?


Always 1st for compliance

Whether it was ELS, FBI, FRS, or MTD, we were there before anyone else, and we’ve never let a customer down on compliance. We get our customers fully prepared every time legislation is announced – such as MTD – well in advance of the new rules taking effect. We have a 42 year track record of going above and beyond to deliver more than just standard compliance.  

We are the largest third-party filer of online documents to the UK government. We submitted nearly four million 2020 Tax Returns – almost as many as all our competitors combined.   

Our strong relationship with HMRC means they work closely with us, request our input, and listen to what we say. We always ensure your voice is heard because we represent the largest volume of accountants, agents and tax filers of any third-party vendor.

Single source of truth 

We cut out one of the biggest problems many accountants face with duplication of tasks by removing the need to re-key data multiple times across different applications. Thanks to our single central database, which creates a single source of truth, once information is entered, our suite of products can use and share this information, providing true integration across shared workflows and processes.


IRIS pays for itself 

That’s what our customers tell us; the amount of time and effort they save using IRIS’s integrated suite outweighs the subscription cost.  IRIS is the only provider with so many solutions under one roof (including HR, payroll), enabling us to cut high costs for firms using multiple software suppliers. We can provide better and cost efficient software packages that can achieve more for you than your current supplier.
