Estimate vs Quote vs Proposal: What Contractors Should Send
Homeowners use these words interchangeably. GCs and commercial clients do not. Sending the wrong document, or the right work under the wrong label, slows approval and confuses payment. Here is how trades usually distinguish estimates, quotes, and proposals, and how our free PDF tool fits (one estimate builder, convert to invoice after approval).

- Name the document honestly — If the price can change after inspection, call it an estimate. If you are committing to a fixed price for defined scope, many shops say quote. Proposals add scope narrative and terms for larger jobs.
- Match the PDF header to search and clarity — Our tool prints ESTIMATE on the PDF, that matches what most US trades search for ("hvac estimate template"). You can still use it for fixed-price quotes; the line items and total matter more than the header word.
- Include valid-until and acceptance — Estimates and quotes should show how long the price holds and where the client signs or approves. Our estimate PDF includes a valid-until date and acceptance line by default.
- Convert after approval — When the customer says yes, use estimate→invoice in the tool: lines copy over, you get a new invoice number, and due date defaults to Net 30.
- Invoice only completed work — Do not re-send an estimate as an invoice. Invoices bill for work done (or progress billings you agree on). Change orders get a new estimate or a revised line block.
Quick comparison
Estimate: projected cost, scope may be refined, valid-until date common. Quote: fixed price for defined scope, often shorter jobs. Proposal: broader sales document, scope story, schedule, terms, sometimes multiple options.
Invoices and receipts come after the job (or a progress milestone). Mixing labels on the same job creates disputes, e.g. sending an "estimate" then charging above it without a change order.
What to put on each document
All three need: who, what, line items or clear scope, total, and how long the price holds. Proposals add exclusions ("not including drywall repair"), payment schedule, and warranty notes.
Regulated trades: license number on the PDF when local rules require it. Our trade spokes pre-fill realistic line items for landscaping, HVAC, plumbing, and electrical, edit before sending.
Using our tool for quotes and proposals
Build on /estimate or a trade estimate spoke. The PDF header stays ESTIMATE; use the notes block for "fixed price quote valid 14 days" or a short scope paragraph for proposal-style jobs.
After the client approves, convert to invoice, no retyping line items. For paid-in-full jobs, use /receipt with amount paid.

Common questions
Is an estimate legally binding?
Usually not the same way a signed fixed-price contract is, it is a good-faith projection unless your terms say otherwise. A quote with defined scope, price, and acceptance can act more like an offer. We are not lawyers; use clear valid-until dates and written approval.
What is the difference between a quote and an estimate?
Colloquially: estimates allow adjustment; quotes imply a firm price for stated scope. In practice many small contractors use one PDF format for both. Our builder labels the PDF ESTIMATE for SEO and clarity; your notes block can say "fixed price quote" if that matches the job.
When do I need a proposal instead?
Multi-phase remodels, commercial bids, and design-build jobs often need a proposal: scope narrative, timeline, exclusions, and sometimes alternates. For a single trade ticket (panel upgrade, drain clearing, lawn install), an itemized estimate is usually enough.
Why does your app not have a separate Quote document type?
One estimate engine covers pre-job pricing for most trades. Separate quote/ tax-invoice types would duplicate the builder without changing the math. See our decisions log, we use ESTIMATE on the PDF and optional UK/AU tax-invoice styling where needed.
Can I convert an estimate to an invoice?
Yes, one click after approval. Line items and parties copy over; invoice number and due date refresh. See /estimate or any trade estimate spoke, then Convert to invoice.
