Why we built this

A ledger underneath Making Tax Digital, built by people who wanted their own numbers to reconcile.

Our mission

Making Tax Digital asks sole traders and landlords to report four times a year instead of once. That is only manageable if the underlying books are already in order, which for most people they are not — the records live across a spreadsheet, a shoebox and a bank app, and get assembled under pressure at the deadline.

We build the part that has to be right first: a ledger that balances, a reconciliation you can trust, and figures that trace back to postings you can point at. Get that straight and the quarterly update stops being an event.

How we build it

🔒

Privacy first

Your financial data stays yours. We don't connect to banks or share your information with third parties. You control your data completely.

⚡

Deterministic by design

Matching, posting, the trial balance and your tax figures are all computed, never estimated. Where we use a language model it writes commentary over numbers that were already worked out, and it goes nowhere near anything tax-related.

✍

Nothing posts unreviewed

Every suggestion arrives as a draft in a queue. You approve it, and the approval is recorded against your name and the time you gave it.

Our story

Flow Money Manager started as a tool for keeping one household's accounts straight, built by someone who wanted the numbers to reconcile without handing a third party the keys to a bank account.

Making Tax Digital for Income Tax changed what was needed. Quarterly reporting demands a real ledger underneath, so that is what we built: double-entry posting, a reconciliation engine, period close, and figures mapped to HMRC's own categories. The privacy stance did not change — you still import your own statements, and we still do not touch your bank.

Our values

  • Transparency: No hidden fees, no surprise charges. What you see is what you get.
  • Privacy: Your data belongs to you. We never sell or share your information.
  • Simplicity: Finance is complex enough. Our tools shouldn't add to that complexity.
  • Empowerment: We give you the tools and insights to make your own financial decisions.
