We want to create an independent tool from SAP using excel or perhaps a PC application to calculate and automate TAXES from Mexico.
We have developed a prototype using excel which will show you the basic functions and UI
In Mexico there is VAT (value added tax) and cashflow tax, both taxes are based on cashflow. In our current prototype we have to conciliate manually expenses and income documents with payments as well as payments dates.
we need you to develop and algorithm that matches payments.
On first stages of development we cannot alter any of our SAP system, you will have to work with what there is, and data exported from SAP. At the moment we cannot grant a SAP user.
