About this app

Flatbill is the invoice maker built for freelancers and solo service providers tired of recurring price hikes and invoice limits.

Why Flatbill?
You pay one annual price for unlimited invoices. No monthly caps. No forced upgrades. No surprise fees. Other invoice apps keep raising prices and cutting invoice limits to push you toward premium tiers. Flatbill doesn't.

What you get:
- Unlimited invoices on a single annual subscription
- Estimates with their own numbering and expiry date, free even on the free plan
- Payment tracking by status: outstanding, unpaid, paid
- Mark invoices as paid with settlement dates
- Deposits, discounts, PO numbers, sales tax and late fees
- Save your service rates and reuse them on every invoice
- Send invoices by email, message or any app you already use
- See what every client owes at a glance
- Manage everything from your phone

Price the job before you bill it
Write an estimate, send it as a PDF, and let your client sign and return it. Estimates run on their own numbering and their own expiry date, so your invoice numbers never skip. An accepted estimate becomes an invoice in a tap, carrying the items and the price the client already approved, and the invoice prints the estimate number so both documents match. Estimates are free and unlimited, on the free plan too, because pricing ten jobs to win three should not cost you anything.

Billing built for how US work gets invoiced
Deposits and partial payments, with the balance due printed on the document. Discounts by dollar or percent, applied before tax. PO numbers in the invoice header, where accounts payable looks for them. Sales tax, payment terms and a monthly late fee, stated on the invoice. Your license number on the letterhead, which several states require for trades.

Get paid into your own account
Choose the platform you already use: Stripe, PayPal, Venmo, Cash App or Zelle. Flatbill prints your payment address on the invoice, with a QR code your client can scan and the amount already filled in where the platform supports it. The money goes straight to you. Flatbill never touches the transaction and takes no cut of your work.

Works on the job site
Everything lives on your phone. No account to create, no signal required, no analytics and no server. Back your history up to a file any time and restore it on a new phone.

Perfect for:
- Freelancers, consultants and designers
- Contractors and home service providers
- Handymen, landscapers, cleaners and trades
- Self-employed and small business owners
- Anyone tired of paying more for fewer features

Start free
The first 3 invoices are free and need no account. Estimates never count against them, and neither does the example invoice the app writes on first launch. Every invite of yours that gets used adds 10 more free invoices, up to 5 invites.

Subscription
Flatbill, annual: $39.99 per year, auto-renewing. Payment is charged to your Google Play account at confirmation of purchase. The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and you can manage or cancel it any time in Google Play.

If you left another invoice app because prices kept rising or invoice limits kept shrinking, Flatbill is built for you.
