The short answer
A fixed total can be workable if the included work is detailed enough to compare and enforce. Ask for scope and exclusions first; an internal labor-rate breakdown is a different request.

Decide what information you actually need
You need to know the products, quantities or locations, installation boundary, finish condition and exclusions. You may also want optional work separated for budget decisions. Those needs do not necessarily require access to the company’s internal payroll or profit calculation. Frame your request around the decision you need to make: comparing deliverables, removing an option or understanding a risk. See CSLB consumer guidance for the applicable official information.
Build a deliverables checklist
List the proposed work in observable terms and ask the bidder to confirm each item. For equipment, use the relevant model or performance description; for finishes, define the area and expected completion state. Include protection, disposal, permits and cleanup where relevant. If the response remains vague, you still do not have a usable comparison even if the total seems attractive.
Ask for alternates instead of reverse-engineering wages
If you want to postpone part of the scope, ask for a price alternate or credit for that defined change. Do not divide the total by your guess of crew hours and call the result the contractor’s wage. A project price can include activities and obligations that are not visible during installation. Equally, that fact does not excuse an unexplained or incomplete scope.
Compare the same commitment
Give competing bidders the same baseline and ask what would cause a price revision. A lump sum with explicit scope differs from a rough estimate with unresolved selections. Record which you received. You can choose not to proceed when the proposal does not provide enough clarity, without declaring that every nonitemized quote is improper.
A lump-sum clarification worksheet
List the end result you expect, then break it into observable components. For each component, ask whether it is included, excluded or subject to an allowance. Record the exact proposal language rather than replacing it with your interpretation. If you cannot tell what condition the space will be left in, that is a scope question to resolve before comparing price.
Add a product column where selections matter. Identify whether the bid names a model, allows an equivalent or assumes an owner selection later. Ask who approves substitutions and how price differences are handled. A single total can still have a precise product commitment, while a long itemized estimate can remain vague about the actual product.
Add a responsibility column for permits, disposal, delivery, protection and restoration. Some jobs need only a few of these rows; tailor the worksheet rather than forcing every project into a renovation template. If a task is excluded, name who will perform it and how it will be coordinated. Excluded does not mean unnecessary.
Next write the decision you need from a price breakdown. If you want to remove an optional item, request an alternate for that item. If you want to compare two methods, request separate scope descriptions and totals. If you want to know whether the contractor is overcharging, recognize that an estimated hourly rate based on your assumptions cannot answer that reliably. Obtain comparable proposals instead.
Finally, ask what would change the price after acceptance. Record unresolved site information and the agreed change procedure. A firm price for defined work should not be confused with an estimate that will be revisited after measurements or investigation. Keep the contractor’s clarification with the eventual agreement. This approach gives you a usable buying decision without requiring the contractor to disclose every internal cost or treating a refusal to expose profit as proof of wrongdoing.
Follow through on the decision
Write the final comparison in terms of outcomes rather than guessed internal costs. For example, record that one proposal includes restoration to a described finish while another excludes it. If you accept an exclusion, identify the separate plan for that work. Ask the selected contractor to incorporate the clarified scope into the signed agreement. Keep pricing alternates labelled so an optional upgrade does not accidentally become part of the assumed base. This leaves a record of what you bought even when the contractor never disclosed an hourly rate or individual markup. The project can then be evaluated against its agreed result rather than a speculative reconstruction of the contractor’s business expenses.
Decision checklist
- Ask for deliverables and exclusions before estimating internal labor costs.
- Identify products, finish condition and the scope of restoration work.
- Request defined alternates when deciding whether to remove optional work.
- Confirm whether the number is a firm commitment or preliminary estimate.
A quote for one installation
Hypothetical example. Imagine an electrical quote includes equipment installation but does not say whether wall repair is included. The first useful question is who restores the wall and to what finish, not how many dollars the electrician earns per hour. Once that boundary is clear, ask competing firms to price the same result. If wall repair is excluded everywhere, budget it as a separate known responsibility.

Must a contractor disclose its profit?
Do not assume that. Focus on the written scope, contract price and information needed for your decision.
Is a detailed quote always better value?
Detail improves clarity. Value still depends on the complete offer, contractor suitability and your priorities.
