REQUEST EXTENSION ON PAYMENT

Dear Felix

[THANK AND COMPLIMENT SUPPLIER FOR PRODUCT/SERVICE, ex. We found your cleaning and disposal services to be exceptional. Indeed, our construction sites have never looked better!]

I have received your invoice #[INVOICE NUMBER] in the amount of $[AMOUNT]. [STATE WHETHER AN INTERIM PAYMENT IS ENCLOSED, ex. I have enclosed our check #4242 for $3,000.00.] [STATE REASON, ex. As you may know, the recent brick-layer strike has adversely but only temporarily affected our liquidity]. Since we wish to continue to do business together, I regret that we forced to remit the balance [DATE, ex. in two weeks].

Although I am confident you understand our situation, allow me to apologize for the delay and assure you that this is an isolated request.

Regards
Lydia
