The general terms and conditions must meet two requirements:
- The terms relating to delivery, payment, liability, guarantee and service must not be an unreasonable burden on your business partner.
- The general terms and conditions must be supplied to the client either before or during the agreement to do business.
You can deliver them in person, send them or print them on the back of the quotation document (with a reference to them in the quotation document). In other words, it is not sufficient simply to refer to your general terms and conditions (whether you have filed them or not) on your printed paper. If you send your terms and conditions only when you send the invoice, they are not valid in law.
