Have you ever helped a VOIP provider figure out VOIP Taxes? I can use your help!
I'm not sure what's the best approach, this might be one:
I have a hosted Freepbx, the USA law has very specific tax charges and fees for VOIP providers. I need a module that will allow me to enter taxable items with their rate, then somehow associate them with the usage of clients, the module will then calculate the owed taxes.
