KashFlow is online accounting software built specifically for UK small businesses. It covers core accounting needs like invoicing, bank reconciliation, VAT returns, payroll, and reporting, without trying to be a global, all-purpose finance suite.
It’s part of the IRIS Software Group ecosystem and is positioned as a practical alternative to tools like Xero or QuickBooks for UK users.
If you run a UK-based business, compliance is non-negotiable. KashFlow is designed around HMRC requirements, including Making Tax Digital (MTD) for VAT. You don’t need to bend a US-first product to fit UK rules.
It’s best for small teams that want straightforward accounting without excessive features or complexity. Accountants also tend to be familiar with it, which helps at year-end.
You connect your bank, create invoices, track expenses, and let KashFlow handle the accounting logic in the background. VAT is calculated automatically, and submissions can be sent directly to HMRC.
Watch-outs: the interface feels dated compared to newer tools, customization is limited, and it’s less flexible for businesses operating outside the UK. Advanced inventory and multi-currency support are not its strong points.
