Which Should You Choose?

The right choice depends on your firm's specific situation. Here is our recommendation for each scenario.

For Most UK Firms

Xero

Xero is the stronger choice for most UK accounting firms. The larger integration ecosystem, unlimited users on all plans, and mature cloud-native platform give it a clear edge. If you are setting up a new firm or switching from desktop software, Xero should be your default starting point.

For Sage Desktop Migrants

Sage Accounting

If your firm currently uses Sage 50 or other Sage desktop products, migrating to Sage Accounting is the path of least resistance. The familiar interface, data migration tools, and continuity within the Sage ecosystem make the transition smoother than switching to an entirely new platform.
