How to translate the terms 'Invoice' and 'Paid' on an invoice?
If you have ensured you have completely translated the language pack in your desired language and uploaded it as per the process given here, then there are two possibilities for this issue.
Reason 1: You are referring to an enum term like 'Paid' or 'Invoice'. If this is the case, then you need to open your specific language's folder and edit the fields in the file "enums.csv" in the folder named 'internal'. Click here to read more.
Reason 2: If you have changed the enums as well but you still see one or two words not translated then it could be some parameters you have entered in the Chargebee site settings.
Example: Settings->Configure Chargebee->Invoices, Credit Notes, and Quotes-> General settings - has organization address format that needs to be entered manually.
Check for all the manually entered parameters like in the sample given below. Ensure you have translated all of it into your desired language in the admin console invoice settings.
