- Step #1 Gather together all the past due invoices, and stamp them PAST DUE.
- Step #2 If you have an email address or phone number with a contact name for your client, email them or call them and give them the information on the past due invoices and let them know their account is on hold.
- Step #3 Mail the invoices to your client with return receipt requested or send them in a flat rate Priority Mail envelope with delivery confirmation.
- Step #4 Send a letter with these invoices stating the age, invoice numbers, their PO#, your account #, total amount due, and any other pertinent information.
- Step #5 Tell them their account is on hold and you will not be shipping any more products or providing any services to them until these invoices are paid. You can include a self addressed envelope and state that you have enclosed an envelope for them to send their check. Give them a date, to have this paid to you.
