What should I include in a business proposal?

Describe the scope in specific language

Replace vague phrases such as “complete repairs” with the actual work you priced. List major tasks, quantities or areas when they matter. The scope should give both sides the same picture of the finished job.

Separate inclusions and exclusions

Exclusions protect the estimate from assumptions. If demolition, disposal, permits, premium materials, after-hours work or hidden-condition repairs are not included, say so. This is especially important when the customer could reasonably assume an item is part of the price.

Show a price that matches the scope

Depending on the job, you may present one fixed project price, line items, options or allowances. The customer-facing proposal does not need to expose your internal markup, but your internal estimate should still account for labor, materials, subcontractors, overhead and profit.

State payment terms and deposits

Explain the deposit, progress payments, final payment and accepted methods. If you use late-payment terms, state them before approval rather than adding them after work is complete.

Explain how changes are approved

A simple change-order rule can prevent “while you're here” work from silently expanding the job. State that work outside the agreed scope may require written approval and additional price or time.

Add timing without promising what you cannot control

Give an expected start window or duration when useful, and identify important dependencies such as material availability, weather, site access or customer selections.

Include validity and acceptance

Prices can become stale. Add an expiration date or validity period and a clear acceptance step such as signature or electronic approval.
