Concrete Calculator

Concrete Calculator helps contractors and sales reps create fast, accurate concrete quotes and submit jobs for full installation. The app lets you enter slab dimensions and location to generate instant pricing, produce professional proposals, obtain signatures, and hand the project off for scheduling, foundation drawings, site checks and concrete installation.

Key Features

Instant location-based pricing with automatic frost-wall depth by city and county for accurate local estimates. Support for both 4-inch and 6-inch slab calculations with quick material and volume estimates. Generate clean, professional quotes, collect signatures, and submit jobs directly through the app. A handoff workflow lets you submit closed deals to a partner for scheduling, foundation drawings, site checks, and full installation while keeping proposal and signature records in the app.

Advantages

Concrete Calculator speeds quoting by producing accurate bids in seconds without manual calculations, reduces overhead by allowing a partner to manage crews and materials after the sale, and improves close rates with professional, signable proposals generated on site. The interface is designed for sales reps and contractors who need to quote anywhere and close faster.

Disadvantages

Concrete Calculator is limited to 4-inch and 6-inch slab presets, so projects that require other thicknesses need external calculation. The app requires location access to determine frost depth and local pricing, which limits some offline use. Jobs are handed off to a partner after submission, which reduces direct control over scheduling and crew selection.
