Quick answer: Give subcontractors the same defined request, then compare what each quote includes before using its total. Check work boundaries, selections, quantities, access, restoration and exclusions. Resolve “by others” tasks so they do not disappear from your customer estimate.

A low subcontractor total can be useful when it prices the required work. It becomes a problem when your proposal promises tasks that the trade quote never covered. The comparison needs to happen before those assumptions reach the customer.

Issue one scope request to everyone

Identify the property, work areas, proposed tasks, available drawings or photos and known selections. Label inspection limits. State the requested output, such as itemized scope, exclusions, pricing basis and relevant scheduling information.

Share only project information the recipient needs and is authorized to receive. If the scope changes during the quoting process, send the same update to the affected bidders so their replies remain comparable.

Normalize the quotes before choosing

Subcontractor quote comparison matrix
Element	Quote A	Quote B	Clarification
Work areas and tasks	[scope]	[scope]	[difference]
Materials and selections	[basis]	[basis]	[pending model or grade]
Access and openings	[included or excluded]	[included or excluded]	[owner]
Finish restoration	[boundary]	[boundary]	[owner]
Disposal and cleanup	[treatment]	[treatment]	[missing work]
Price validity and timing	[stated terms]	[stated terms]	[confirmation needed]

Mark unspecified items as unclear. Do not infer inclusion from a broad trade label. Obtain the explanation before adjusting your customer price.

Assign every “by others” item

If the plumbing quote excludes wall openings and restoration, decide which trade or crew handles them. If the electrician expects a clear work area, identify who provides it. Include necessary protection and coordination in the right place.

Shared work can also be duplicated. Check whether two quotes both include a full disposal or mobilization amount for the same operation. Resolve the scope, not just the arithmetic.

Use a specific clarification request

“For quote [reference], please confirm whether [task] in [location] is included. The customer scope requires [boundary or specification]. If excluded, please identify the exclusion and provide the price or information needed for that work. Please also confirm the selection and quantity basis.”

This is an adaptable message template, not an instruction to send it automatically. Preserve the reply with the quote so the estimator can see what the final figure covers.

Carry the quote's limits into your proposal

Do not turn a provisional subcontractor figure into an unconditional promise. If their price depends on a selection or access check, resolve it or keep the assumption clearly identified. Check the relevant quote date and validity before sending your customer estimate.

Your selling price also needs to account for your defined role in coordination and the business pricing method you use. A subcontractor total is a cost input, not automatically the price you should charge the customer.

Frequently asked questions

Should I always choose the lowest trade quote?

Evaluate the required scope, suitability and project requirements. The lowest total may price a different set of tasks.

What does “by others” mean?

It identifies work outside that quote. Your project still needs a named owner for any such work required by the customer scope.

Can I use a verbal quote?

Record and confirm the scope and price basis in an appropriate written form before relying on it in the customer proposal.
