Crunch combines accountancy services with its own accounting software. The software side covers MTD ITSA, sending invoices, tracking expenses, connecting your bank, reconciling transactions, and managing payroll. The accountancy side includes self assessment filing, year end account filing, VAT returns, tax returns, payroll, bookkeeping, contractor and IR35 support, and company setup. Crunch also offers a price match promise on like-for-like services. It suits sole traders and limited companies that want software and accountant support in one place.
Which One Should You Choose?
Start with the job you need done. If you want one platform for invoicing, payroll, and reporting, an all-in-one tool may fit. If Making Tax Digital is your main concern, look for software that states it is MTD-compatible and offers guidance. If you mainly need simple bookkeeping, a low-cost option with no user or transaction limits may suit. If you would rather have accountants alongside the software, a combined service could be a better match. Check the pricing page for the plan that fits your business type, and confirm the features you rely on are included.
Final Thoughts
There is no single answer for every UK small business. Xero offers a broad all-in-one platform, FreeAgent leans into Making Tax Digital for small businesses and landlords, Pandle keeps bookkeeping simple at a low price, KashFlow covers end-to-end accounting with direct HMRC VAT submission, and Crunch pairs software with accountancy services. The right choice depends on your business type, the features you need, and whether you want accountant support. Use the quotes above as a starting point, then check each company's current pricing and features before deciding.
