I have to say hands down the hardest part of this business for me has een collecting. It was easy to just have people leave checks and what not when I had 50 customers, now it's hard to keep up with it all. We just signed up with an eletronic payment processing company, hopefully I can get a lot of customers on board and that will help. Having to float the business expenses while I am waiting on checks to come in is often a big source of stess. Anyone relate? What are the the ways you guys have found it effective to collect?
