Most of my clients use QBO. And I have a nice solution to push invoices from FileMaker.
I have 2 clients on QB Desktop and for them I use Transaction Pro Importer.
It works, but it is extremely cumbersome. One client gave up and said it was less steps to re-key the invoice in QB then to go through all the steps required for Transaction Pro.
I did explore FMBooks Connector a few years ago but the dev time was too high. The freelancer I work with for things like this wanted 50+ hours to build the interface, where as QBO took 10.
If all my clients used QBD I would gladly make the investment, but QBO has become the new standard.
Does anyone have other options to recommend, or believe the work should not be 50 hours?
