Estimate App With Client Signature: Quote On Site

Why an estimate app with client signature wins the job on site

An estimate app with client signature lets you photograph the job, get the itemized estimate, add your markup, and send the quote while you are still at the house. The client signs to approve. SimplyWise Cost Estimator is $29.99/mo or $239.99/yr after a 7-day free trial.

Plenty of jobs slip away in the days after the visit. You drive home and build the quote at night, while the client keeps talking to two other contractors. By the time your number lands, the moment has passed.

Sending the quote from the driveway fixes that. The client is standing in the room you just walked, and the scope is fresh. They can ask a question and get an answer in the same minute, and a signature on the spot turns a maybe into a yes.

How to get a client signature on site, in 4 steps

Here is the whole flow. It fits in the time you spend saying goodbye at the door.

1. Photograph the job

   Stand at the work and take a photo. SimplyWise Cost Estimator turns it into an itemized estimate in about 6 seconds, with material, labor and fee lines.

2. Check the lines and add your markup

   Edit any line you want to change. The app has built-in markups, so your margin sits in the estimate before the client sees it.

3. Send the quote from the house

   Tap Send Estimate and send it to your client while you are still standing there. They get a professional, branded quote.

4. The client signs to approve

   The signing feature is for your client. They sign the quote to approve it, and you know you have the job before you pull out of the driveway.

What happens after the client signs

The signature approves the estimate. The next job is getting paid, and that runs through an invoice.

Open the saved estimate and tap the three dots in the top right corner. Select Create Invoice. The app asks you to fill in a few more fields, and you can preview the invoice before you send it to your client.

Deposits are the part people miss. The estimate has no deposit field. To take a deposit or down payment, add it to the invoice.

Open the invoice, tap Edit, tap Add Field, and choose Payment Schedule. Then add the payment details.

So the order is simple. Estimate first, signature second, invoice with the deposit third.

What to put in the quote before they sign

A signature is only as good as what sits above it. A client who signs a vague quote will argue about it later. Spend two minutes on these three things before you hit send.

• Scope. Say what you will do, room by room or item by item. Use the line items, so each one says what and how much and nobody has to guess.
• Exclusions. Say what the price does not cover: permits, paint, trash haul away, or anything the client might assume is included. Short and plain wins.
• Payment terms. Say when you want paid and how. If you take a deposit, say so in the quote, then put it on the invoice.

This is general job advice, not legal advice. If a job needs a formal contract, ask your own advisor what it should say. For a fuller template, see our construction proposal template.

Client signature support, compared

Every estimate app with client signature handles the signing step a little differently. Here is what each vendor says on its own pages, read October 9, 2026.

An estimate app with client signature is common now. What differs is the rest of the job. SimplyWise starts from a photo, builds the itemized estimate in about 6 seconds, and keeps the whole feature set on one plan.
