Counter reply the reminder

Counter reply the reminder for payment (asking your clients to make purchases and pay later on)

We thank you for your letter dated 7th June, 20…

We are indeed sorry to learn the difficulties you have been facing during the last three months. Had we known it earlier, we would never have reminded for the payment?

Please rest assured, we shall extend you all possible co-operation. You may remit us payment in October or in November as convenient to you. As for purchases, please feel free to send your orders and they will be complied with as promptly as in the past.

Thanking you,
