The Key Difference: CT600 and Companies House

Here's what most people don't realise: Xero, FreeAgent, and QuickBooks don't file your Corporation Tax or Companies House accounts. They only do the bookkeeping. You still need to pay an accountant £500-2000/year to file your actual company accounts.

ByteLogic is building the only affordable software that takes you from daily transactions all the way through to filed accounts at Companies House. The free tier already covers payroll, bookkeeping, reports, and more.
