A company stamp is a quick mark of authenticity — a way to show a document genuinely comes from your business. Once you have one (physical or as a transparent image), here's where it earns its keep.

On paper

The everyday places a company chop appears:

  • Invoices and receipts — stamped near the signature or company details.
  • Delivery orders and purchase orders — to acknowledge goods sent or received.
  • Letters and letterheads — official correspondence and confirmations.
  • Cheques, vouchers and forms — many banks and agencies expect a company stamp alongside an authorised signature.

On screen (digital)

You don't need to print to stamp. Download a transparent PNG of your design and drop it onto digital documents — invoices, quotations, PDFs and emails — so it sits cleanly over the page with no white box. For a true-size, single-colour version with crop marks, use the print-ready PDF. It's the same design you'd use on a physical stamp, reused digitally.

What a stamp does — and doesn't do

A company stamp signals authenticity and authority, but it isn't magic:

  • It is not a signature substitute. Pair it with an authorised person's signature where one is needed.
  • It is not a common seal. A common seal is a separate embossing device with a specific legal role — see company stamp vs common seal.
  • In Singapore a company stamp is not legally mandatory — most firms simply find it useful. See is a company stamp mandatory.

Good practice

Keep the impression legible — a clean 22mm round with your name and registration number covers most needs. Stamp in a consistent spot near the signature, and avoid covering text you might need to read later. For guidance on the wording, see what to put on a company stamp.
