The full loop

Three things done flawlessly. Nothing else.

Billflow focuses on the exact loop that matters to freelancers: capture every billable minute, generate a polished invoice automatically, and move money faster.

Track

Start a timer with one click. Log time against any client or project from any device. Forget to track? Add it manually in seconds — Billflow doesn't punish you for being human.

Invoice

At the end of any period, hit generate. Billflow pulls your tracked hours, applies your rate, and produces a clean, professional PDF invoice — no spreadsheets, no copy-pasting.

Get paid

Send invoices by email or share a payment link. Automatic payment reminders chase the late ones so you don't have to. Know exactly which invoices are open, overdue, or settled.

"I used to spend three hours every month building invoices in a Google Doc. Now it takes me four minutes. I actually look forward to billing day."

Features

Everything a solo freelancer needs. Nothing you don't.

Time tracking

Log hours the way you actually work

One-click timer starts while you work. Or add time manually after the fact — we know how freelancing actually goes. Round up, add notes, tag by project. Every minute captured exactly as you choose.

  • Start/stop timer from any device
  • Manual time entry for forgotten hours
  • Multi-client, multi-project support
  • Tag entries with rates and notes

Invoice generation

Polished invoices in under a minute

Hit generate and Billflow builds a professional PDF invoice from your tracked hours — client name, itemized entries, your rate, your branding. No spreadsheet. No manual calculation. No embarrassing templates.

  • Auto-populated from your time log
  • Your logo, colors, and payment details
  • PDF and shareable payment link
  • Custom line items and discounts
Payment tracking

Stop chasing clients. Let Billflow do it.

Automatic payment reminders go out on your schedule — polite but persistent. See every invoice status at a glance: sent, viewed, overdue, paid. Know exactly what you're owed and what just landed.

  • Automatic overdue reminders on your schedule
  • Real-time "invoice viewed" notifications
  • Dashboard showing total owed vs. paid
  • Payment history by client

"I used to invoice on a Sunday night in a spreadsheet. Now I do it in the app on a Friday afternoon and start the weekend without worrying about money."

"The payment reminders alone were worth the $12. My average invoice collection time went from 24 days to 11."
