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.
Chase invoices
while you sleep.
Create a professional invoice in under a minute. Fynmerge handles the follow-up automatically — reminders at day 7, 14, and 30, with Stripe and GoCardless payment links on every invoice.
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
Real results for real UK businesses
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.
