Direct sales & freelancers
Ali Hussein founded a direct-sales company and worked closely with external providers for many years, facing the same tension between scope, hours, and invoices that agency teams see every day.
New standards for agency
finance operations.
Billyr was born from real pain, not a PowerPoint slide. We build the software we would have needed when invoice review was hot desks and cold hope.
Built by someone who’s seen invoice chaos behind the desk — from practice, not a pitch deck.
The story
How Billyr came to be.
No textbook, just folders, due dates, and hours that looked plausible until they didn’t.
End of the month
Invoices arrived. Roles, work, line items: all vaguely plausible. Often a quick look and a nod through, quietly hoping it was fine.
The turning point
At some point it was clear: it isn’t always right. The frustration led to a decision to tie review and operational truth together permanently — not in spreadsheets, but in real software.
These situations are not edge cases. Everyone who runs projects with external workers eventually faces the same PDFs, the same follow-up questions, and the same time pressure before the wire transfer.
Billyr was born from this pain — not as a theoretical product, but as an answer to a problem many know and rarely name out loud: replacing trust with proof, chaos with a clear chain of order, work, and invoice.
We measure our progress by how much wasted time, overpayment risk, and end-of-month stress we remove from finance ops. That's what this is about.
We want to reach 100 million euros in savings for agencies.
Every invoice Billyr reviews is one step closer to that goal — and one step away from silent losses at the end of the month.

Values that guide us.
These values shape our product decisions, support, and how we work with partners — not as a slide, but as a bar.
We’re measured by your day-to-day
Retainers, sprints, freelancer billing: features come from your workflows, not from fence-drawing in Excel.
Safe and auditable
Review trails you can export, explain, and defend — from VAT plausibility to logged hours.
You own the solution
Integrations that respect your tools. Not a replacement for your PM software — the last mile to payment: you close the gap between ticket and payout.
Forward-looking
We build API-first, testable, and multi-tenant because your client load is not getting smaller.
