Import invoices from other software to QuickBooks Online.
One of my clients is a global company which issues invoices to its many subsidiaries across the world. They use their own intranet software to issue the invoices to their subsidiaries. They mostly use different accounting softwares in different countries but they want to get everyone on the same software and I have already converted the US company to QuickBooks Online.
What they need is to be able to create an export-import interface between their own intranet and QuickBooks Online. Is there a way to do this with a specific format of an Excel file? Can QuickBooks Online execute custom code after an import? Is this something that could be done with an app and if so what is the best app for this sort of thing?
