Different/Multiple Currency Payments

Hello @SantiagoDPS -
Welcome to the OpenEMR community and its forum. It is a large and active community with a lot of helpful members.
However, what you ask sounds like a feature development project rather than a bug-fix or small tweak of the code. For something like that you’d probably do best to use one of the approaches detailed in this post:

If you have learned some php and have developed a code snippet that you think will meet the needs of your project you can always post that code here and ask for suggestions!
Good luck- Harley
