How to Prepare a Professional Construction Quotation

A quotation is a commercial document, not a price list. Here is the structure that gets accepted, and the items most contractors leave out.

Most quotations that get queried, delayed or rejected fail for the same reasons: the scope is vague, the exclusions are missing, and the client cannot tell what they are actually paying for. A well-structured quotation prevents most of that before it starts.

Start with a clear scope of works. Before any pricing, state in plain language what is included. A client reading only the first page should understand the job. If you are quoting a shop fit-out, say which areas, which trades, and what condition you are taking over the space in.

Break items down at the right level. One line saying \"Renovation works — $45,000\" invites negotiation on the whole number. Twenty-eight lines with quantities, units and rates invites discussion on individual items, which is a far better conversation to have. Break down far enough to justify the price, not so far that the document becomes unreadable.

Use consistent item descriptions. A useful standard format: supply and installation of the item, complete with the supporting components, and all necessary accessories. This closes the gap where a client assumes conduit, fittings or supports were included in the headline item.

State your exclusions explicitly. Hacking, making good, statutory submissions, permits, after-hours working, disposal, temporary power. If it is not in your price, it must be written down. Exclusions are not a weakness in a quotation — they are the part that protects your margin when scope drifts.

List your assumptions. If you priced from a drawing that lacked dimensions, say so. If you assumed the existing electrical supply is adequate, say so. Assumptions are the fastest route to a fair variation later.

Close with commercial terms. Payment schedule, validity period, lead times, and what happens if the programme changes. Two weeks validity is standard for fit-out work; longer if material prices are stable.

The document should look like it came from a company that has done this before. Consistent header, consistent numbering, correct totals. Clients do read the presentation as a signal about how the site work will run.
