Built by someone who runs a real UK business too.
Running BACKBENCHER and selling on eBay and Amazon means I live the same operational reality UK accountancy firms know well: VAT schemes, payment platforms, marketplace fees, customs codes, late-paying customers, Corporation Tax estimates, year-end accruals.
The regulatory and bookkeeping load on a small UK business is real, expensive, and unforgiving. Fynvro began as the tool I wished my own accountant had been using — and the platform I'd want if I ran a practice.
"UK accountancy firms deserve software built by someone who has actually filed VAT returns, paid Corporation Tax, and chased late invoices — not by someone who learned about UK accountancy from a marketing brief."
