again, you're assuming incorrectly that just because they factor at 20%, the Factor get's to keep the other 80%.
That's just not how factoring works. You can't run a business by giving away 80% of your revenue, grossly inflated or not.
The Factor will take their fee after all invoices are processed and return the remaining sum to the company. This is how factoring works. Praxsyn deals with workmans comp so a lot of the invoicing effort wills stretch out years.
