The people behind flexinvoice

We started flexinvoice with one frustration: billing software built by accountants, not by the people who send invoices every day.

Our story

Billing software was broken. So we fixed it.

It started in 2021, between two design projects and a late-night invoice. The tools everyone recommended were either painfully slow, absurdly expensive, or both. So we built a 30-line spreadsheet that did the job — and then kept building.

Today flexinvoice powers invoices for 12,000+ freelancers across 40 countries. We stayed true to the original idea: no registration, no paywall, no clutter. Just fast, professional billing tools that respect your time and your money.

Our mission

Every freelancer deserves to get paid fast

Late invoices and confusing billing tools don't just cost you money — they cost you momentum. We exist to remove every barrier between finishing work and getting paid.

Free, always

Invoicing shouldn't be a subscription line item. Our core tools are free today and will stay free — no bait-and-switch pricing.

Fast by design

Every screen, button and calculation is built for speed. If an invoice takes more than a minute, we've failed.

Private by default

No accounts mean no data harvesting. Your invoices and financial details never touch our servers.

What makes us different

Not another accounting suite

No sign-up wall

Big invoicing platforms make you create an account, then sell you a trial, then upsell you. We make you an invoice — full stop.

Built for the solo pro

We optimize for one person, one laptop and 20 clients — not for enterprise approval workflows nobody asked for.

Beautiful, always

Your invoice is your brand. Ours are clean, modern and print-perfect — clients notice the difference.

Tax-savvy

Built-in VAT/tax calculators and clear tax lines keep you compliant in any currency — without an accountant on speed dial.
