Make payment records easier to read

Choose the message that matches the transaction

For bookkeepers, office teams and small businesses marking invoices, receipts and refund records. Keep a consistent meaning for each stamp across your team.

1

A general Paid mark

Choose Paid, Paid Outline or Paid With Thanks when a simple completion message is enough.

2

Record the payment method

Compare wording for cash, cheque, credit card, Direct Debit, Bacs and PayPal when the method needs to appear on the paper record.

3

Handle refund paperwork

Choose Refund or Refunded to match your process. Use a completion mark only after the refund has been confirmed.

Match the impression to the available space

Compare the dimensions on each product with a clear area on your invoice or receipt. Refund and Refunded include shallow 45 × 6mm versions and 43 × 16mm versions; other designs have their own sizes.

The Paid By Bacs impression measures 35 × 17mm.

Check the design, then choose the ink

The product gallery shows the supplied wording and layout. Current listings offer black, red, blue, green and violet; each product’s variant selector shows what you can order.

The listed water-based ink is for standard absorbent paper and card. Test first on spare material.

Order and use

From choosing a stamp to marking the record

1

Check the complete wording

These are fixed designs. Read the product gallery, compare the size and select the available ink colour before adding to your basket.

2

Confirm and test

Match the transaction to the correct record. Make a test impression on spare paper, then stamp on a flat, supported surface.

3

Keep it working

Use a verified replacement-pad link where the product supplies one. If no pad is linked, ask for the exact model match before ordering.

Useful answers

Paid stamp questions

Can I change the wording on a Paid stamp?

No. These ready-made stamps have the fixed wording and design shown in their product galleries. Choose a personalised stamp for your own wording.

Which ink colours can I choose?

The current listings offer black, red, blue, green and violet. Check the live variant selector for the colours available to order on your chosen product.

Do I need a separate ink pad?

No. These self-inking stamps contain an internal ink pad.

Which surfaces are suitable?

The listed water-based ink is intended for standard absorbent paper and card. Test on a spare piece first; do not assume compatibility with glossy, coated or non-porous surfaces.

Which replacement pad should I order?

Use a verified replacement-pad link on the product page where one is provided. Otherwise ask Stamp Ninja to confirm the pad for your exact model; impression size alone is not a compatibility guide.

What is the difference between Refund and Refunded?

Refund identifies the subject or stage according to your own process. Refunded states that a refund has been completed. Confirm the transaction before applying a completion mark; stamping does not process a payment or update your records.

Need your own wording?

Use a personalised stamp for a business name, invoice reference field or a different message.
