Using Avalara for Sales Tax, need a way to differentiate Tiktok sales from webstore transactions.

[gdrinkh2o]

I currently use Avalara (avaTax) for sales tax calculations and returns . Challenge is there doesn't seem to be any discernable difference between order number info that comes from Shopify to Avalara, based on the sales channel. I primarily sell on Tiktok and my own webstore/app. Meaning, I need to find a way to identify TikTok orders in Avalara so I'm not double taxed (TikTok withholds/remits tax on its own). 

It appears Shopify auto-generates their own unique order number for every transaction. If I could somehow add an identifier to that number (ie. TTxxxxxx) then I could strip out the sales in Avalara. 

Thanks in adavnce!

Hey there, @gdrinkh2o! Thanks for taking the time to reach out to the Shopify Community Forums with your question around adding identifiers to these orders within Avalara!

I quickly consulted with the Tax Team regarding your question and they advised that it may be worthwhile to reach out to Avalara's Support Team regarding this request. I have a link to their Support Pages here that you can use to connect with them regarding this request to see what options they may have available to help Avalara differentiate between these orders and their sources! -Imogen

Thanks. Yes- I had already contacted them and waiting on further direction. Their position remains that unless there is some type of identifying number, code, info, etc. that comes from shopify, there is no way for them to separate.
