FAQ

 

Can split ship taxes be configured without using Avalara?

Split ship tax functionality in commonsku is currently designed to work exclusively with the Avalara integration. At this time, you must have Avalara enabled to configure and calculate split ship taxes, and this integration is available to users on the Advanced and Enterprise plans. 

 

What if my SKUs are not unique?
You’ll need to edit your product variants so that each has a unique SKU before you can proceed.

 

Can I use SKUs from my warehouse or ERP system?
Yes, as long as each SKU is unique per variant.

 

Where can I find the Avalara tax summary?
In the Review tab, you can download both the summary and raw tax response data.

 

If I make changes to my order, will I need to re-configure my split ship taxes?

 Yes. If you update your order for example, by adjusting quantities, colors, sizes, or decoration locations, the split ship taxes  will  display a status of Incomplete configuration. In this case, you’ll need to reconfigure your split ship taxes again to ensure accurate calculations.
