You need to capture information fast, generate a professional estimate before you leave the driveway, and attach a photo of the damage before you forget what you saw. This guide covers every field tool a solo contractor needs — all in one app.

The Problem

Field contractors need tools that work in the field.

Most estimating apps were designed for an office. They're slow to load, require internet, and don't connect to your lead tracking or mileage. A contractor on a job site needs something that works instantly, stores everything locally, and connects the estimate to the lead it was for.


Estimates

Professional PDF estimates built in 5 minutes.

Lead Score generates professional PDF estimates directly from the lead card. Add line items, materials, and labor. Preview before sending. Convert to invoice with one tap when the job is won. The estimate lives alongside the lead score, activity log, and mileage record — one complete record per job.


Voice Notes

Capture field details when typing isn't possible.

Contractors are frequently on ladders, in crawlspaces, or in trucks when they need to capture information. Voice notes attach directly to the lead card in the activity log — so the recording is there when you sit down to write the proposal, not buried in a separate voice memo app.


The Full Picture

One lead card. Everything about the job.

A Lead Score lead card contains the lead score, contact details, project notes, activity log, voice notes, photo attachments, estimate, invoice, mileage records, and follow-up dates — all in one place, all stored locally. The complete pre-sale record for every job you've ever qualified.



FAQ

Common questions about field tools & estimates

Can I send estimates directly from Lead Score?×
Yes. Lead Score generates a professional PDF estimate and lets you email it directly from the app, share it via any messaging app, or save it to your phone. The estimate is linked to the lead card so you always know which estimate belongs to which lead.
Does Lead Score work offline for estimates?+
Yes. All data is stored locally. You can create, edit, and save estimates with no internet connection. The estimate syncs to the lead card automatically when you're back online — though since there's no cloud, there's nothing to sync. Everything just lives on your device.
Can I attach photos from a job site visit to a lead?+
Yes. Lead Score supports photo and document attachments on every lead card. Take a photo during the qualifying visit and attach it directly — so the image is there when you write the proposal, not floating in your camera roll.
How is Lead Score different from Joist for estimates?+
Joist is a standalone estimating app — it starts at the estimate, not the lead. Lead Score starts at the lead qualification and generates the estimate as part of the same workflow. The estimate is connected to the lead score, activity log, and mileage record — Joist has none of that context.
Can I convert an estimate to an invoice in Lead Score?+
Yes. When a lead is marked Won, you can convert the estimate to an invoice with one tap. The invoice inherits all the line items, client details, and job description from the estimate.
