Avalara continues to develop links to financial applications and Open Systems has become the latest vendor for whom the sales-and-use tax vendor has developed an integration with its AvaTax product. Avalara is starting with a link to Open System’s Traverse Accounting line and will follow with a connection to the company’s Open Systems Accounting Software. As with all the links developed for AvaTax, this means the sales-and-use tax engine can scour the universe for rate changes and handle calculations.
