How it works

From work completed to payment received.

Billflow removes the paperwork between doing the work and getting paid.

01

Complete the work

Your team finishes a job, booking, project or support session — exactly as they do today.

02

Billflow understands it

The customer, service, hours, parts, prices and payment terms are pulled out of the detail you already record.

03

Invoice created

A professional invoice is drafted automatically. Review and approve it before anything is sent.

04

Get paid

The invoice goes to your customer, payment status is tracked, and late payers get a polite nudge.

Live demonstration

Just tell Billflow what happened.

One sentence in. A professional, VAT-ready invoice out — waiting for your approval.
