Thank you for your help!

I just installed Front Accounting to help me to manage my small business and Setting up the company I get the fields fot Official Company Numer and GSTNo, but I don´t know what they mean.

I´m not an accounting man and also i´m from Mexico. Here in Mexico we have an official number for a tax contributor, called RFC, and it should be included in any invoice of a sale or a purchase, to identify my business.

Is the GSTNo or the Official Company Number equivalent to the RFC in Mexico?

Also what is Add Price from Std Cost?
