  4. A final letter of demand
  5. A final phone call
  6. Hand over to collections

Keys to Successful Collection Phone Calls

The first step is to phone them and follow a script so that you are in control of the conversation. Record the phone call if possible (note: in most states, you will have to inform the individual that they are being recorded). If you don’t have the ability to record your call then you need to take detailed notes of what the customer said and when you can expect payment. It’s very important to follow up via a written record (email), detailing all that was decided upon during the phone conversation, and ask them to confirm. The more detailed proof of any agreements of correspondence you have, the more likely it is that your customer will pay the past due invoice.

Successful Collections Phone Calls:

  • Begin with an ice breaker, including some small talk
  • Reiterate that the business relationship is important to you
  • Explain that you have plans to improve your business, and need to monitor your income closely to achieve those business goals
  • Include the date the invoice relates to
  • Include a description of the invoice
  • Include the invoice number
  • Include the date the invoice was sent
  • Include the the date the invoice was due due
  • Refer to your payment policies
  • Get your customer to commit to a specific date
