Sales-and-use tax vendor Avalara has added integration to four more software products as the company continues to expand its alliances across the ERP space. These are AvaTax Calc for Retail with Microsoft Dynamics AX for Retail and Microsoft Dynamics RMS and AvaTax for WennSoft and AvaTAx for Encore’s Recurring Contract Billing. The WennSoft links provide a connection to that company’s Field Service and Job Cost modules for Dynamics GP. Encore markets a variety of add-on products for Dynamics AX and GP.
