We've had a customer for 1+ years with 150+ products/services being invoiced over that time. I've only now realised that the customer is actually divided into separate sister companies under one sub-parent company. The problem now is that I want to separate the invoices to the specific sister companies that have all been set up now with the original one as their sub-parent.
I can't see this being a problem with reconciliation or tax purposes as none of the amounts are changing and all companies are still under the same tax bracket, so nothing should change except the customer name and contact information. Is this possible?
Also I know you can technically go through each one individually and change the name on the invoice, but my main question is can this be done quicker as I've got 150+ invoices and then 150+ payments to all change the names of the customers to.
