Adding an invoice from another platform

Hi, I'm trying to work out the best way to add an invoice from another platform (Worksome) to my Quickbooks account. There is an app called Zapier which apparently will link my Worksome invoice to one created in Quickbooks, but the process looks confusing and I'm not 100% certain that I won't be sending multiple invoices out to my customer (one from Worksome, one from Quickbooks).  Is there a way I can reference the payment I receive from the other platform's invoice into Quickbooks, so that it tallies up with the payment received in my work bank account?  Do I need to create a duplicate invoice in Quickbooks, matching the details of the Worksome invoice, but not send it out to the client?
