BUYING CRITERIA
What UK accountants should evaluate first
The real buying question is not only bookkeeping. The platform must support VAT workflows, client collaboration, bank feeds, permissions, reporting, accountant access, and clean exports for year-end work.
- Best for accounting practices: Xero plus practice-side tools, or TaxCalc / IRIS when compliance workflow is central.
- Best for small business clients: Xero or QuickBooks.
- Best for freelancers: FreeAgent or FreshBooks depending on workflow simplicity.
- Best for VAT and MTD workflows: Xero, Sage, FreeAgent, and the practice-side UK stack around them.
- Best for payroll-adjacent needs: QuickBooks or Sage, depending on local workflow and product fit.

TRADE-OFFS
When not to choose the default favorites
- Do not choose Xero by default if the client base is simple and the extra ecosystem depth is not needed.
- Do not choose QuickBooks by default if plan complexity and localization fit create unnecessary friction for the practice.
- Do not choose FreeAgent as a universal answer for every client type if the practice handles more complex or multi-layered bookkeeping needs.
