Is there any possible way of sending a QBO invoice up with a custom tax amount? I am taking invoices from my Shopify and Etsy stores and trying to send them up to QBO. In these cases I know the total tax amount already as Shopify and Etsy already calculated it and I just want to apply it to the QBO invoice.
If not I'm going to have to add tax as a line item :(
Please see this thread- Quickbooks IPP v3 sales tax issue
NOte that you will still have to assign an existing taxCoderef and the pass the oevrride flat amount.
