Free — no credit card required

Free invoice generator

Make an invoice that looks like it came from a real business, send it, and know where it stands. BillFlow’s invoice generator is free to use — every feature, no credit card, and no cap on how many invoices you create.

  • Unlimited invoices, free
  • Automatic, gap-free numbering
  • Inclusive, exclusive and compound taxes
  • Print-perfect PDF export
  • Partial payments and running balances

An invoice your customer can actually act on

The editor shows the sheet as your customer will receive it — letterhead, items, totals, terms and payment instructions — with the panel beside it holding the parts you fill in. There is no preview step, because what you are editing is already the preview.

The items table takes quantities, unit prices, per-line discounts and per-line taxes, and totals recalculate as you type. Custom columns can carry formulas that reference other columns, so margins, weights or unit conversions are computed rather than typed.

How to create an invoice

Numbering that cannot collide or leave gaps

A draft has no number. The moment you issue an invoice it takes the next number in its sequence and keeps it, which means two people issuing at the same moment can never be handed the same one, and a draft you discard never burns a number out of the sequence.

The prefix and pattern are yours to set — INV-0001, INV-2026-0001, or whatever your accountant expects — under Settings › Numbering.

How document numbering works

Taxes and currencies that add up

Tax can be inclusive or exclusive, flat or compound, applied per line or across the document. Each currency rounds to its own minor unit, so totals match the figure your accounting software expects rather than drifting by a cent.

Taxes, currencies and rounding

Payments, and what is still outstanding

Record a payment — full or partial — and the invoice status follows the balance: Issued, Sent, Partially Paid, Paid or Overdue. Overpayments are shown rather than quietly absorbed, and every entry stays in the invoice’s payment history where it can be corrected or removed.

The dashboard totals what is outstanding and what is overdue for whatever period you pick, so the question “who still owes us” has an answer you do not have to assemble by hand.

Questions people ask

Is this invoice generator really free?
Yes. There is no paid tier, no trial clock and no feature held back behind a price. Unlimited invoices, PDF export, your own branding, taxes, reports and unlimited team members are all included on every account.
Can I create an invoice without signing up?
You need a free account, which takes about a minute and asks only for your name, email, a password and your organisation’s name. The account is what lets an invoice keep its number, remember its customer and track its payments — things a throwaway generator cannot do.
Can I download the invoice as a PDF?
Yes. Every invoice renders to a PDF that matches the on-screen sheet exactly, and you can export any selection of invoices together as a single ZIP file.
Can I put my logo and colours on the invoice?
Yes. Set your organisation’s logo, colours and watermark once under Settings, pick a template for invoices, and every invoice and PDF uses them from then on.
Does it handle partial payments?
Yes. Record any amount against an invoice and the status follows the remaining balance rather than flipping straight to Paid. The full payment history stays on the invoice.
