Hi!
I am trying to translate a letter of credit into Spanish but I can't find the right translation for this: "work progress certificate"
could somebody tell me what a work progress certificate means?

many thanks in advance

Welcome to the forums.

It would be a help to have the entire sentence, but without full context it is probably a certification of the progress of the work which is the subject of a licence or contract.

A [work progress] certificate.
