Dear [NAME, ex. Link Building],

[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.

Sincerely,

[YOUR NAME, ex. Jill Jones]
