Bid Builder Guide

What to include in a contractor bid contract

A bid contract is more than a price. It is a written agreement that explains the work, the price, the payment plan, and what happens when the scope changes.

Project scope

Describe the work in plain language. Include the exact areas being worked on, materials assumed, cleanup expectations, access requirements, and what finished work means.

Price summary

Show the client a clean total. Depending on your business and local rules, you may also show tax, deposit due, and payment schedule. Keep private profit and overhead math out of the client version unless there is a business reason to show it.

Exclusions

Exclusions prevent confusion. Common exclusions include hidden damage, structural repairs, permit fees, utility conflicts, after-hours work, hazardous materials, and client-requested add-ons.

Change orders

A change-order section should say that added work, hidden conditions, material changes, or client requests must be approved in writing before the additional work continues.

Signatures

Signature lines create a simple approval checkpoint. They do not replace professional legal review, but they are better than a vague verbal approval.
