If I change a tax code on a previously used item code, will it affect prior months?


I'd like to update our item mapping but want to be sure it will not affect orders that were invoiced already.

  • Item Mapping changes in the admin console as well as in your accounting software are only going forward type changes.
  • Transactions already calculated and invoiced will not be changed.
  • The only way your older invoices will be changed or affected is if you recalculate on them after making the item mapping change.
