Hello- I'm a new independent biller who signed my first client, a Chiropractor, 2 months ago. His billing situation was a mess, but I'm now almost caught up. He now wants me to tackle his past collections, and posting of payments. My contract with him states my pricing on clean billing, but we agreed to leave the collection and posting issue for another time. My question is: What should I charge for collections of past due accounts, and posting of payments?? (I'll do the posting via remote access to his office computer)
