How to write an estimate customers actually sign

An estimate gets signed when the customer can see exactly what they’re getting, what it costs, and how to say yes in one step. So list the work in plain words, price it from your saved items so it’s consistent, give options when there’s a real choice, and ask for the signature while you’re still there, on your phone or by a link they open later. If the job needs materials, put a deposit on it so the signature and the first payment happen together.

What should every estimate include?

• Your business details: name, phone, email, and your license number if your trade requires it.
• The customer and the job address.
• The scope, line by line, in words the customer uses. “Replace 40-gallon gas water heater, haul away old unit” beats “WH R&R”.
• Quantities and prices for each line, materials separate from labor where it helps.
• Tax and the total.
• What’s not included, if there’s an obvious question (“drywall repair after access is quoted separately”).
• How long the price holds.
• The deposit, if any, and when the rest is due.

How do you price it so it holds up?

Build it from saved line items instead of typing prices fresh each time. Your service call, your hourly rate and your common installs should each be one tap, at the price you’ve decided on. It keeps you from underpricing on a tired Friday, and it means two estimates for the same job come out the same.

Then check the total against what you know the job takes. If it feels light, it probably is. It’s easier to explain a fair price once than to eat the difference.

Should you offer options?

When there’s a real choice, yes. “Repair the valve” or “replace the unit”, “standard” or “high-efficiency”: two or three options let the customer pick instead of deciding whether to hire you at all. Keep each option complete, with its own total, so nobody has to do math.

How do you get it signed on the spot?

Turn your phone around. In FieldFlow the customer can sign the estimate right on your phone, and both of you get the signed PDF with a record of who signed and when. That’s the best moment: they’ve just seen the problem and heard your explanation.

If they want to think it over, send it. They open the link, and sign with a code FieldFlow emails them to confirm it’s really them. Sent estimates nobody has answered get a follow-up email if you switch estimate reminders on, so a quiet “let me think about it” doesn’t just disappear.

When should you ask for a deposit?

When you’re buying materials, holding a date on your calendar, or the job is big enough that walking away would hurt. Put the deposit on the estimate as a fixed amount or a percentage. In FieldFlow, the moment the customer signs, the deposit invoice is made and they can pay it right there, by card or by bank transfer where your Stripe account supports it.

Some states limit how much you can take up front on home improvement work, so check your state’s rules before you set your deposit. Our post on taking deposits goes through it.

What happens after they sign?

The signed estimate becomes the invoice in one tap, with nothing retyped, and any deposit already paid is credited against it. If the scope changes partway through, write the extra work up as its own estimate and get that signed too, instead of editing what was already agreed.

The short version

Plain words, saved prices, a clear total, options where they’re real, and a signature before you leave. That’s what FieldFlow’s estimates are built around, at $19/month for the whole business with a 90-day free trial.

Questions owners ask

How long should an estimate be valid?

Long enough for the customer to decide, short enough that your material prices still hold. Thirty days is a common default; FieldFlow sets an estimate to expire 30 days after it's issued unless you change the date or the number of days, and after that the customer can't sign it from the link. You can extend an expired estimate and the same link works again.

Should I give one price or options?

Offer options when there's a real choice, like repair versus replace or a standard versus a premium unit. Two or three clear options are easier to say yes to than one take-it-or-leave-it number. More than three and people stall.

What if the customer wants changes after signing?

Write the extra work up as its own estimate and get that signed too, rather than editing the signed one. The signed estimate stays a clean record of what was agreed, and the change has its own price and signature.

Is an e-signature legally binding?

The federal ESIGN Act says a signature or contract in interstate commerce may not be denied legal effect just because it is electronic. Home improvement contracts can carry extra state requirements, though, so for anything large or unusual ask a local attorney or your trade association what your state requires.
