The Finance Manager,

Dear Sir,

I am pleased to convey this that your request for bulk payment discount has been approved, and management has decided to offer you a 10% discount on all your pending payments if you settle them within 10 days of this date. It is further notified that this offer will be deemed cancelled if you fail to accept it in writing within two days. Moreover, I also want to mention here that delayed payments may cause cessation of supplies without any further notice. We hope that we will keep trading with you in the future.

Sincerely,
Brad Edwin
