Recently our company received this email from a GNG contractor who hired us to work on Del Taco projects, but has not paid invoices since January 4, 2020: "We have compiled and reviewed all remaining outstanding invoices from Total Services, LLC. and are ready to issue payments. However, we still have not received the stainless steel tables that are included in your invoices. When will you be able to deliver these tables so we can pay these invoices?" There are 14 invoices, excluding the invoice he is referring to regarding the tables. A deposit was made for the tables' invoice. The tables are being made by a third-party and the balance is due in order to receive them. Our question is how should we word our reply to their email?
