Invoice number stamp maker with an incrementing reference
An invoice number stamp maker where each impression takes the next number in a server-held sequence, so no invoice reference is ever duplicated.
Invoice number stamp maker with an incrementing reference templates, ready to edit
Open the stamp maker with any of these
Every preview on this page carries a faint Estamplab watermark. Your own download does not: the editor renders your stamp again, clean, as a transparent PNG, an SVG or a PDF. See the full template library.
A duplicated invoice number is the kind of error that surfaces months later during a reconciliation, when nobody remembers which of the two was real. A counter that cannot repeat removes the failure entirely.
What you get
- INV- prefix, or whatever your ledger already uses.
- Fixed-width numbering, so references sort correctly in a spreadsheet.
- A date alongside the number, resolved when the invoice is stamped.
- One sequence per stamp, so invoices and receipts do not share a counter.
How to make it
- Open the stamp maker and pick a shape, or start from a template.
- Type your wording, then set the colour, border and size.
- Add the date, time, serial number or logo, and position each one.
- Preview it live, then download. Designing and previewing are free.
Questions
Can the prefix match our existing numbering?
Yes. Set any prefix you like and the padding width, so a stamp can continue the convention your accounts already use.
Will it keep counting next year?
It counts continuously. If you want a yearly reset, that is a decision worth making before you start, because changing it later leaves an ambiguous stretch where two numbers look the same.
What if a stamped invoice is voided?
The number is spent. Gaps in a sequence are visible and that is the point: a missing number tells you to go and find out what happened to it.
