hi everyone
just thought i would update you on this situation.
I contacted the non payer (and no longer customer) and said if they didn't contact me by certain day then i would instruct debt collection people.
I gave her the option to pay in installments if she was having problems making the payment. This was the 3rd communication.
1) original agreement signed, and invoice issued
2) reminder invoice
3) threat of debt collection and damaged credit rating.
it worked, but don't know if i could actually act on this if i had to? did i lie?
