Transactions booked in a customer’s SAP system before implementation of Taxmarc can be run through the Taxmarc engine after installation.
This will significantly decrease the time spent on UAT and regression testing. For example an existing sales or purchase invoice can be used used to execute an indirect tax determination using Taxmarc. The Taxmarc result can be compared with the actual posting. This can reduce a lot of time in creating new test data end to end and it guarantees that all possible business scenarios have been tested. Taxmarc can offer this functionality because it can serve both as an internal (add-on) and external indirect tax engine.
