A Sales Agreement is a contract that sets out the terms of sales (whether this consists of one or multiple orders) between a supplier and one of their customers.
Terms and conditions, on the other hand, are a set of standard terms created by the supplier that are intended to apply to all sales the supplier makes to all customers. Certain requirements must be met for them to apply to a contract. For example, the terms and conditions should be brought to a customer’s attention before the customer makes an order.
