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 in seconds
Build professional invoices and estimates from a clean, mobile-first form. Add line items, quantities, rates, discounts, and tax — totals and invoice numbers are handled for you.
Know the moment a client opens it
Get a push notification when a client views your invoice or replies to an estimate. No more wondering whether it landed in spam.
Paid, unpaid, overdue — at a glance
Every invoice moves through Draft, Sent, Viewed, and Paid. Overdue invoices stand out, so you know exactly who to follow up with.
Estimate to invoice in one tap
Clients accept or decline estimates online. When one is approved, convert it to an invoice with one tap — line items and totals carry over.
Send by link, email, WhatsApp, or PDF
Share a secure link through any app, email the client directly, open WhatsApp with a prefilled message, send the PDF, or print it.
Clients don't need an app
Clients open invoices and estimates in any web browser. They can view, download a PDF, or respond without installing anything or creating an account.
Record payments
Mark invoices paid as money arrives and see the balance due for every client.
Clients and saved items
Keep a client list with balances, import contacts from your phone, and reuse saved items and tax presets so repeat invoices take seconds.
Reports and tax totals
See revenue, paid and unpaid totals, and tax collected by month and year — handy at tax time.
14 invoice templates
Choose from 14 professional layouts, all carrying your business logo. The Classic layout is free; the rest come with Pro.
Automatic payment reminders
Schedule email reminders before, on, and after the due date so late invoices follow up on themselves.
Signatures and photo attachments
Sign invoices and estimates on screen, and attach photos of the work, receipts, or site conditions.
Multiple taxes
Apply more than one tax to an invoice — for example, a state and a city sales tax, or GST and PST.
Multiple businesses
Run more than one business from one account and switch between them, each with its own details, logo, and currency.
Export reports and data
Export reports and client statements as CSV or PDF for your accountant or bookkeeping software.
