60+ UK banks. Sync transactions through FCA-regulated Open Banking.
What it’s like now
Running your work is hard enough. The paperwork shouldn’t be.
Receipts scattered everywhere
Shoeboxes, wallets, email folders. You know they’re somewhere. It just shouldn’t be this hard.
Spreadsheets that never add up
Manual entry, copy-paste errors, broken formulas. Hours lost to work that should be automatic.
VAT returns that take a whole day
Calculating boxes by hand, logging into HMRC, double-checking every number. There has to be a faster way.
Tax deadlines that loom
Gathering documents, second-guessing deductions, filing at the last minute. It doesn’t need to be this stressful.

Self-employment tax, on autopilot.
Snap receipts when you have them, connect your bank, and get on with your work. When tax time comes, everything's ready.
