The basic concept of integrating the sales tax service into all kinds of eCommerce platforms, accounting software or POS systems is that a merchant system calls out to the Exactor system to post sales transactions and get back the tax amounts. The method of communication is a simple HTTP POST request, where you send an XML payload (using the Exactor XML schema) containing the transaction data and receive an XML response that contains the tax data.
At the end of each period, Exactor automatically generates the sales tax returns for all of the states where there is sales tax nexus. You can have multiple points of integration where Exactor touches the transaction, such as at the order management system or the Shopping Cart level; the system Invoice level, or bulk uploads etc.
