Tip:
Something that has helped us from the headaches and assuring we get payed.
If you have an office assistant, and you/your tech is at the job receiving a cc payment, you can inform the customer you will get them a receipt, run inside of your van/shut the door, and call your office assistant and have them run the card for you...than just stamp your invoice w/ a "paid" stamp.
that way by the time u get to the office and run the cc u know it won't have any chances of being declined, saves a trip back to custy's house if the only other form of payment is a check.
we dont accept checks mailed to us, as the client tends to either forget to send or they never send it.
...i once worked for a co that went immediately to client's bank to cash the check...they informed the client they must "secure funds"...that way they knew checks would clear the same day.
