Customer Signature On Invoice is a formal agreement that serves as strong proof of customer acceptance. By signing an invoice, the customer is legally agreeing to the terms and conditions outlined by the business. Not only does it demonstrate a customer’s understanding of the sale but it also provides clear evidence of the transaction in case legal action needs to be taken down the road. This signature acts as a powerful safeguard for both the business and the customer, so make sure to make this practice part of your regular invoicing process.
