When selecting a moving service, be sure you are well aware of the types of payment they accept. It does you no good to offer the mover a credit card when he's expecting a certified check. Fortunately, most moving services are hip with the times, accepting most modern forms of payment.
Although you can conduct most of your business on the phone, it's best to have the moving service come to your house for an estimate. Most companies offer a free estimate service, which can save you a lot of heartache due to misunderstandings later on in the process.
