## What is Clamp Pro?

Clamp runs the whole job from your phone: the estimate, the proposal, the contract, change orders and the final invoice, with a customer portal for e-signing and your mileage and time on site tracked for you.

Built for residential contractors who quote, run and invoice the job, often in the same day.

ONE WORKFLOW, FIRST CALL TO FINAL INVOICE
- Five documents, each built from the one before it: design agreement, estimate, proposal, change order, invoice
- Change orders update the signed contract, so verbal changes stop costing you
- Payment schedules: a deposit, milestones and a final payment, each invoiced from the contract
- Sales tax at the rate you enter, plus customer credits and refunds
- Every status in one place: sent, signed, invoiced, outstanding, paid
- Punch lists that close the job out, shared by text or PDF

DESCRIBE THE JOB. GET AN ESTIMATE.
- Type the job the way you would say it out loud and get an itemized, priced draft back
- Remodels and new homes: one estimator detects which you described
- Every line broken out by trade, with assemblies, quantities, rates and labor hours you can inspect
- Revise the draft with a follow-up prompt, then save your own rates and templates

CUSTOMER PORTAL AND E-SIGNING (ASSISTANT AND TEAMS)
- The homeowner opens a link and sees their job. No password, no app
- E-signing on their phone, with up to five signers per document
- Project updates, photos and decisions they answer from their phone
- Appointment reminders by email that customers can confirm
- Bounced emails flagged Not delivered so you can fix and resend

MILEAGE AND TIME ON SITE, TRACKED FOR YOU
- Drives detected by GPS in the background; you review each trip before it counts
- Time on site logged automatically when you arrive at and leave a saved job site
- IRS mileage rates applied, ready for tax time

KNOW WHAT THE JOB COST
- Receipts, purchase orders and vendor bills tied to the job that caused them
- Budget from the estimate against what you have spent, by labor, materials and subs
- An accountant export package at tax time

THE SCHEDULE (ASSISTANT AND TEAMS)
- Installs, deliveries, inspections and work days on each job in the Jobsites tab
- Custom schedule types and email reminders
- With Teams, crew and subs on the shared schedule: they confirm or propose dates and share photos

KNOW WHERE EVERYTHING STANDS
- A daily briefing of overdue invoices, follow-ups, appointments and open proposals
- Sales on Home: close rate, revenue won, open pipeline and why leads were lost
- Close rate by lead source, so you know which sources turn into work
- Five-factor lead scoring before you drive: a clear yes, no or maybe

WORK AS A TEAM (TEAMS)
- Up to 10 accounts on one business, each with their own sign-in and one of five roles
- Unlimited subs, free for them and never a seat

YOUR DATA
- Leads, documents, photos, mileage, time, receipts and job costing work offline
- AI estimates, the portal, e-signing, email, Teams, cloud backup and the web view need a connection
- No account needed to start
- Backup, restore, CSV export and bulk import

PLANS
Solo: the full job workflow, offline, with device backup and 3 free AI credits. Assistant adds the customer portal, e-signatures, the job schedule, cloud backup, email reminders, a read-only web view and 25 AI credits a month. Teams adds up to 10 accounts, the shared schedule, unlimited sub invites and 50 AI credits a month shared by the team. An estimate is 1 credit; a revision is half.

### 5/5 — Remarkable replacement over mileiq

*2026-05-22*

As a business owner tracking mileage is essential for my consulting business. The tracking on this app alone is worth the download. I have found it to be more intuitive design wise than mileiq. This app is way more affordable and I am looking forward to leveraging the leads portion of this app as well

### 5/5 — Great app for business owners

*2026-04-20*

If you are looking to organize your leads, invoices, and track profit/expenses this is the way to go

### 5/5 — Better leads, faster

*2026-04-18*

The app’s qualifying function is excellent, and it continues to improve with new features being added regularly. It’s a valuable tool for small business owners who want to stop wasting time on unqualified leads and focus on the ones that are the right fit.

### 5/5 — Clean workflow

*2026-04-18*

Great way to keep track of my entire workflow in one spot. Able to gain extra insights out of each lead on why I didn’t close and and can quickly add reminders when I need to follow up.

### 4/5 — What would I do without it?

*2026-04-17*

So here I thought I understood all the ins and outs of running my plumbing company but thank God this app really does structure the ins and outs of what it means to be on top of things, especially stuff I overlooked in the past. This is my new favorite app to guide our projects and has special creatures attached like invoice creating, financial tracking, mileage tax and more. Well worth it, especially if you’re just getting started with your business.
