The bill is a different currency from the currency that is normally used in Syngency.
1. Go into the specific payment / credit note / tax line, and enter an amount in the payment field.
2. Activate the Contact within Quickbooks.
3. Either manually create the Credit Memo in Quickbooks OR delete the credit note in Syngency, wait for a bit (an hour) and then re-add the note to the Bill.
4. If you have a bill in Syngency that uses a different currency, manually create bills that use alternate currencies in Quickbooks.

To be treated as non-taxable, items must be assigned a Tax Category in Autotask and a Sales Tax Rate in QuickBooks Online that have a 0% tax rate. For the non-US version of QuickBooks, this configuration is a requirement.
To resolve the error:
1. Set up a Tax Category in Autotask and set the Tax to 0%.
Make sure to set up this Tax against the Tax Category for every appropriate Tax Region.
2. Set up a Sales Tax Rate in QuickBooks Online with a 0% Tax Rate.
Make sure it is named identically to the Tax you created in Autotask.
3. Retry the invoice sync by clearing ERROR from the Invoice Number field in Invoice History in Autotask.
