Just a thought: collecting money is the most important thing a business does. If the accounting software is standing in the way, it is worth considering replacing it with something that does not stand in the way as an alternative to outsourcing billing and collections.

In particular because outsourcing accounting is a very very common business practice and their are well established standards for the people who perform the service. And anyway, outsourcing billing and collections is outsourcing accounting.

Good luck.
