How can I add characters or letters like ‘INV’ in Invoice Number? When Invoice number is set to automatic, letters are being skipped. Need to manually add those since company needs so.

@Mahfuzur_Rahman

Sir, Good Day!

I can see only 2 options here, whether to set the reference as automatic or add default characters. So, shall we get the result in ‘INV-001’ format?

@sherin, you cannot get that format automatically. You can prepopulate the “INV-” as @Mahfuzur_Rahman described, but you would then have to enter the number manually.
