A contractor estimate should help both parties test the scope before anyone commits to a fixed price. The prefilled document separates labor, materials, equipment and subcontracted work, which makes revisions easier than changing one lump-sum figure.
Use one line per meaningful phase or cost category and add the assumptions that control the price. If the customer removes work or selects a different material, issue a revised estimate with a new date instead of silently replacing the original.
Estimate from quantities and assumptions
Record the dimensions, counts, finish level, access and customer-supplied items behind each number. A rate without its unit is difficult to verify; label hours, days, square feet, fixtures or lump-sum allowances directly in the description.
Keep subcontractor allowances distinct from your own labor. When the outside bid arrives, the customer can see exactly which part of the estimate changed.
Control revisions before the job starts
Date each version and summarize what changed. Once the final scope is known, create a contractor quote that states the price, validity, acceptance method and payment milestones.
An estimate is also an internal feedback tool: compare estimated quantities and hours with the final invoice after completion to improve future pricing.

Frequently asked questions
What is the difference between an estimate and a bid?
Usage varies. An estimate usually communicates an expected cost based on assumptions, while a bid or quote may be a firmer offer. Use explicit wording instead of relying on the document label alone.
Should contractor overhead be a separate line?
It can be included in rates or shown separately. Whichever method you use, apply it consistently and explain any fee the customer must approve.
How long should an estimate remain valid?
Choose a period that reflects supplier pricing, workload and scheduling. Use the actual expiry date rather than relying only on vague wording.
Can I reuse this contractor estimate?
Yes. Save an editable Word or Excel copy as your starting point, or return to the browser and replace the customer, scope, quantities and rates.
