Thanks @KevinJ of Kansas @Jamie @C_Billings for your replies. The reason we are looking for a tax solution is because we are close to launching SCA and our customer base is end-users (B2C) and initially we will only be shipping within the US. Therefore, we need to be able to calculate correct taxes on the web store and also during sales order creation. Avalara did a great job during the demo and we feel they satisfy all of our needs but we wanted to see what else is out there to compare features and cost.
