How to change COUNTRY NAME and add STAMP on invoice and quotation

Hello all,

I want modify these feautures:
1./ I want change COUNTRY NAME because some special requirement. Example: HONG KONG → HONG KONG SAR in all field of invoiceninja
2./ I want add stamp to the invoice and quotes? How can I add this?

I am running the InvoiceNinja self-hosted 5.2.5.
Thank you!


  1. It may work to add a custom translation for “country_Hong Kong” on Settings > Localization
  2. Maybe you can use the built in created_at or updated_at fields, otherwise you could add a custom field but would need to set it manually

For the stamp, if I want PNG file to add in the front invoice is okay?

Sorry, I misread it as timestamp.

@ben any thoughts on adding a stamp, maybe using a custom dropdown field with the image as base64?

@call2vn it’d be awesome if you could provide an example? Example screenshot, drawing, whatever fits easiest for you :slight_smile:

Hi Ben,

This is my sample of my stamp images.STAMP-FULLSIZE-RS

And I want put the stamp on the invoice and quotation like this sample

Thank you!

hi @ben , can you check it for me?

That should be possible using a custom design. Open invoice editor in your admin panel, add just add basic HTML tag with an image. That should be it.

sir, can you help me with the stamp?
Any pdf sample for Stamp or where i can get it?
