After integrating Avalara and enrolling in the SST program, we had to map tax category codes and inventory ID’s to tasks used in billing. We started with tax category codes and only Avalara. The duplicated line items did not begin until we enrolled in the SST program and began using inventory ID’s (as instructed by Avalara).
Has anyone experienced this issue and found a resolution? The duplicate line items appear whether it’s an older project (prior to Avalara integration) or a new project (after integration). Also, we use milestone billing for projects.
