ConcretePro: Slab Calculator

Run your whole concrete business from your phone. ConcretePro is the all-in-one app for concrete and flatwork pros. Measure the pour, quote the job, get it approved on the spot, invoice it, and get paid. No per-user fees. No cut of your payments. Works offline.

MEASURE THE POUR, GET YARDS AND BAGS
Enter the slab, footing, column, or wall and ConcretePro figures the volume for you: cubic yards, bags of 80, 60, and 40 pound mix, and an optional gravel base, with your waste factor. Over a yard? It tells you when ready-mix beats bags. Add multiple pours to one job and it totals them.

CLOSE THE JOB AND GET PAID
- Approve and e-sign: hand the customer your phone to approve and sign the quote on the spot
- Deposits and discounts: take money up front, adjust pricing, and track the balance
- Review requests: ask happy customers for a Google review in one tap after they pay

WE NEVER TAKE A CUT OF YOUR PAYMENTS
Most field service apps run a card processor and skim a percentage off every payment you collect. ConcretePro does not. Your customer pays you straight through your own Venmo, Cash App, PayPal, or card link. You keep all of what the app touches.

FEATURE-COMPLETE AT A FRACTION OF THE PRICE
The big field service platforms charge forty to eighty dollars a month per user and take a percentage of every card payment. ConcretePro gives you the same job-closing tools — estimates, e-signatures, deposits, invoicing, and getting paid — for about ten dollars a month, with no per-user fees and no payment skim.

YOUR DATA STAYS ON YOUR PHONE
ConcretePro works fully offline and keeps your business data on your device, not on our servers. No account required.

Built by a one person shop, for the trades. If you pour concrete for a living and you are tired of doing yardage math on a notepad, this is for you.

Always confirm thickness, mix, and reinforcement against your project requirements. ConcretePro provides material estimates for convenience, not structural or engineering advice.
