Know your cash runway. Chase invoices automatically. Never be surprised by a tax bill.
Your full financial picture, live
Bank balances, invoices, tax, and cash flow — connected and updating automatically.
Your complete financial picture
Finally
Connect every bank account and accounting tool you use. Fynmerge transforms that data into cash visibility, financial reports, and proactive alerts — so you run your business on facts, not guesswork.
Every account
Every tool — One place
Connect all your UK bank accounts via Open Banking and your accounting software — Xero, QuickBooks, FreeAgent, or Sage — in a single click. Fynmerge pulls everything together automatically, so your financial picture is always complete and always current.
See everything
Decide with certainty
Every morning, Fynmerge gives you a single number that matters — how many days of cash you have. Backed by live bank balances, outstanding invoices, and known outgoings, merged into one real-time dashboard you can trust.
Reports that answer
real questions
Generate a clear financial overview across all your connected accounts in seconds. See revenue, expenses, and net cash movement by period — then export a branded report to share with your accountant, board, or investors.
Never miss a deadline
Never get a surprise bill
Fynmerge automatically sets aside the right percentage for tax as you earn, tracks every MTD submission deadline, and reminds you of self-assessment milestones — months before they're due, not days.
Stop chasing.
Let it run itself.
Most tools mark an invoice overdue and stop there. Fynmerge sends a real, graduated sequence — three messages, three tones, one Stripe or GoCardless payment link on every one. You keep the relationship; we handle the awkward part.
Know the real cost
before you commit
Before your next hire, Fynmerge shows you the full picture — salary, employer NI at 15%, pension, and exactly how many days it shaves off your runway. Auto-updated each time HMRC changes rates.
Up and running
in under 10 minutes
What our design partners say
Before Fynmerge, I had no idea what my cash position was until I hit a problem. Now I get a morning update and I actually sleep better. The invoice chasing alone has saved me 4 hours a week.
The hiring cost modeller stopped me from making a very expensive mistake. I thought I could afford a junior hire — Fynmerge showed me it would have cut my runway by 3 months. Genuinely invaluable.
We switched from four separate tools — Xero, a spreadsheet, Monzo, and a reminder app. Fynmerge replaces all of them. First time in two years I've felt in control of our finances.
