An estimate does two jobs. It wins the work, and it becomes the agreement you point back to when questions come up halfway through the project. A good one is clear enough to sell the job and specific enough to settle arguments.
Here's a free construction estimate template you can download, what to put in each section, and the mistakes that cost contractors money later.

A one-page estimate for contractors and remodelers: client and job site details, scope of work, line items, sales tax, a payment schedule, exclusions, and signature lines so the client can accept it.
What to put in each section
Scope of work
Describe the finished job, not just the tasks. "Remove existing vanity and install new 36-inch vanity with quartz top, faucet, and mirror; patch and paint wall behind" tells the client exactly what they're buying. Most disputes start with a scope that was too short.
Line items
Break the price into pieces the client can follow: demo, materials, labor by trade, disposal. You don't need to show your markup, but a single lump sum invites the question "why does it cost that much?" Line items answer it.
Valid until
Material prices move. A "valid until" date, often 30 days, protects you from honoring a six-month-old number after lumber goes up.
Payment schedule
Put the payment schedule in the estimate, so it's part of what the client signs. A small job might be a deposit and a final payment. A bigger remodel usually runs in stages, like the common 10 / 40 / 30 / 20 schedule. Some states limit how large an upfront deposit on home improvement work can be, so check yours.
Exclusions
List what's not included: permits, appliance installation, painting outside the work area, hidden damage found during demo. Exclusions feel negative to write, but they're the line that saves you when the client assumes something was included.
Acceptance and signatures
A signed estimate is an agreement on scope, price, and payment terms. Get the signature before you order materials. If the scope changes later, handle it with a written, signed change order instead of a conversation on site.
Common estimate mistakes
- Vague scope. "Bathroom remodel, $18,000" sets you up for an argument about what a bathroom remodel includes.
- No exclusions. If it isn't excluded, the client may reasonably think it's included.
- No expiration date. Without one, an old price can come back to bite you.
- No signature. A verbal yes is hard to point to later. A signed estimate isn't.
- Payment terms left out. If the schedule isn't in the estimate, every payment request becomes a negotiation.
Estimate vs. quote vs. bid
The words get used loosely. Generally an estimate is your expected price for the described work, a quote is a fixed price, and a bid is a price submitted in competition for a project, often to a general contractor or owner. What matters most is the language in the document: if the price is fixed, say so; if it can change, say how.
Send estimates clients can sign from their phone
A PDF template works. But a client who has to print, sign, scan, and email it back may take a week to get around to it. BuildSuite Invoicing makes the yes easier:
- Clients open the estimate from a link and sign on their phone. No app or account needed.
- Each signature records the signer's name, time, IP address, device, and a fingerprint of exactly what they signed, with a certificate page on the PDF.
- Add a payment schedule to the estimate. Once it's signed, each payment becomes an invoice in one click.
- Changes go out as numbered change orders the client signs the same way, and the contract total updates automatically.
BuildSuite Invoicing is in early access and launches at $12.99/month. Learn more, and see our free contractor invoice template too.
