It has come to my attention that your company, The Cooking Store has been late with paying their invoices for the past three months.
In order to encourage our customers to pay for their invoices before the due date, we have implemented a discount model where we'll give you 2% off your invoice if you pay us within 10 days of receiving the invoice.
I hope that everything is going well for you and your company. You are one of our biggest customers, and we appreciate your business. If you have any questions, you can feel free to contact me at (555) 555-5555.
