I have a couple of customers that want to only pay by check instead of automatic recurring billing to their credit card or electronic check. One guy says he was scammed and won't pay by credit card again... They both signed one year contracts and live in the same state as me. I much rather would have preferred it autobilled to their credit card but I didn't want to jeapordize the sale so I decided to risk it and let them mail a check... I regret this as I feel it gives them more control. Both clients have been in business many years. Only time will tell if I will have to chase them for money. I auto-invoice them via Freshbooks. Would like to hear others experiences.
