Our favourite number
Know what's safe to take out.
Your bank balance isn't your money — some of it is spoken for. Kempt gives you the one honest number: what you can pay yourself today, without wincing later.
What that feels like
The admin happens. You just see the results.
The tax, already put by.
The bill builds in plain sight all year — so when it arrives, the money is waiting for it.
Invoices that chase themselves home.
Sent, nudged and reconciled — without you watching the inbox.
Every mile counted.
Trips logged and claimed at the proper HMRC rate. No spreadsheet in the glovebox.
What's inside
Everything the money side needs. Nothing it doesn't.
One place for the whole of it — not six apps and a spreadsheet holding hands.
Invoicing
Send them, nudge the late ones, mark them paid when the money lands. Your numbering, your branding, recurring ones on a schedule.
Expenses & mileage
Log costs and trips as you go, categorised for tax. Mileage claimed at the proper HMRC rate, no spreadsheet in the glovebox.
VAT, if registered
Standard or flat rate, tracked all year so the return is ready rather than reconstructed the night before.
Bank import
Bring in a statement and Kempt matches payments to the invoices they belong to — no double entry, no guesswork.
Tax, set aside
Every invoice updates what you owe and what's safe to take out, so the bill never ambushes you in January.
Year-end, ready
Your figures — Self Assessment or Corporation Tax — fall out of the books you've already kept. No scramble.
Built for your setup
However you're set up, it fits.
Sole trader
Self Assessment
Income, expenses and mileage in one place, kept the simple way — your year-end figures ready by April, not rebuilt from a carrier bag of receipts.
Limited company
Corporation Tax · CT600
Dividends and director's pay, the Corporation Tax bill building in plain sight, and the safe-to-withdraw number that keeps it all honest.
Partnership
SA800 · per partner
The partnership return and each partner's share — profit split cleanly down the middle, or however you've agreed, without the spreadsheet arguments.
Kempt is free while we're new. It's a crowded space, and we'd rather earn a reputation than invoice you for one.
There'll be a fair price eventually — and founding users will keep a deal worth having. Until then: use it, lean on it, tell us where it falls short.
Hand your accountant a year they can actually work with.
Everything arrives already tidy — reconciled, categorised, nothing missing. They'll be suspicious. And if you don't use one, the year-end numbers are ready anyway.
Free while we're new. No card, no tiers, no nonsense. Privacy
