How did Avalara, ADP Taxware, Exactor and Speedtax earn their designation as certified service providers (CSPs)?
Peterson: A CSP must undergo nearly a year’s analysis by the Streamline states. That analysis is to make sure the company’s tax decision software accurately reflects the sales tax law in each of the states. In addition each company must be able to integrate its software into a merchant’s accounting software and be able to file tax returns and remit taxes to the states.
