The second piece of documentation that every tender needs is terms and conditions. Most tender writers include a standard terms and conditions that apply to all jobs. Most terms and conditions will state the rules of the job and the standards expected from you, the bidder. Terms and conditions can cover approval of delivery of products or services, access to client information, and what constitutes additional charges.
A big advantage to including a terms and conditions document into a tender is that the information is not confidential, it can be handed out freely to other job requests, and it outlines the general framework for how you and your company operate to complete a job.
