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

- Leads, documents, photos, mileage, time, receipts and job costing work offline
