Everything you need to invoice and get paid
Invoiceflint gives freelancers and small businesses a fast, mobile-first way to send professional invoices and estimates — and, crucially, to see what happens after you hit send.
Create invoices and estimates from your phone
Build professional invoices and estimates from a clean, mobile-first form. Add line items, quantities, rates, and tax — Invoiceflint handles the math and formatting so every document looks polished.
Live read receipts
See the exact moment a client opens your invoice. No more wondering whether it landed — a read receipt tells you when to follow up and when to sit tight.
Payment status tracking
Every invoice moves through clear stages: Draft → Sent → Viewed → Paid. A glance tells you which invoices are outstanding and which are done.
Estimates that become invoices in one tap
Send an estimate to win the job. When the client approves it, convert it into an invoice with a single tap — line items, client details, and totals carry over automatically.
Share a secure link — no app required for clients
Clients open your invoice or estimate through a secure link in any web browser. They can view, download a PDF, or respond to an estimate without installing anything or creating an account.
Works on iPhone and Android
Invoiceflint is available on the Apple App Store and Google Play, so you can invoice from whichever phone you carry.
