Frequently Asked Questions
What accounting software do UK startups use?
Xero and QuickBooks are common UK cloud-accounting choices. For an entry-level option, compare the published free plans from Zoho Books, Pandle, Clear Books and QuickFile against your required features and MTD obligations.
When should a startup upgrade from free accounting software?
When you become VAT-registered (mandatory MTD compliance), hire your first employee (payroll needed), or raise investment (investor-grade reporting required). Most startups outgrow free tools at Series A.
Does accounting software help with startup fundraising?
Indirectly — clean, well-organised accounts in Xero or QuickBooks make due diligence much smoother. Investors and accountants are familiar with both platforms and can access reports directly.
Can accounting software handle R&D tax credit claims?
Accounting software tracks the expenses that go into an R&D claim, but the claim itself is typically prepared by a specialist. Our R&D Tax Credit Estimator tool can give you an initial estimate of your potential claim.
