What a Concrete job looks like in SideWRK.
The concrete job as the app lays it out — your own cost sitting on it, and the estimate your customer approves from their phone.
Built for concrete side work — in one app
Branded estimates & invoices
Send clean, itemized estimates and numbered invoices with your business name, logo, and license number on them — text or email, straight from your phone. You look like a real shop because you are one.
Customers approve from their phone
Send a branded approval link. Your customer reviews the estimate, sees the photos, and taps Approve — logged with their name, the time, and the amount, with re-authorization if the job grows.
Real profit, not just revenue
Every material carries a private "your cost" the customer never sees — so the Money tab shows what you actually made on each job, not just what you charged.
Photos that document the work
Snap the before, the problem, and the finished job and text it to the customer — proof that gets jobs approved and a record of the work after you leave.
One flow, start to paid
Estimate → approve → invoice → paid, all on one job, all on your phone. Jobs flip to Paid automatically when the balance hits zero.
811 & silica, flagged
Every dig needs an 811 utility-locate, and cutting concrete means silica control. SideWRK flags both on the job and tracks your permit — the rules surfaced, the ticket and controls left to you. Never legal advice.

What should a concrete contractor charge?
Concrete flatwork is priced by the square foot, and the finish plus the prep drive the total. Here's how it's priced, plus a free concrete cost calculator to price it.
Flatwork per square foot
Standard flatwork — driveways, patios, walks — commonly runs about $6–$12 a square foot installed, depending on your market and the spec.
Finish upgrades
Stamped, colored, and exposed-aggregate finishes price well above a broom finish — the decorative work is where margin lives.
Demo, thickness, access
Tear-out and haul-off, extra thickness and rebar, grading, and hard access all add to the base square-foot price.
Concrete cost calculator
Price a driveway before you leave the truck — square footage in, honest number out.
The concrete rate behind SideWRK's estimating defaults is $8/sq ft, with 50% of a typical ticket paying for time rather than materials. Both numbers come from our 2026 Side-Work Rate Report, which publishes the same figures for all 42 trades.

Nothing above is behind a higher tier. There is no higher tier.
The slab cured.
The coating job was in the pour all along — same floor, two tickets.
One app, every trade.
Every trade — all 42 on one $19/mo plan.
Add epoxy flooring — you poured the slab, now coat it so it lasts.
The garage and shop floors you pour are the same floors that get eaten by oil, road salt, and hot tires. Coating them in epoxy or polyaspartic is a natural add-on: you already know the concrete, and both jobs price by the square foot, so it's the same estimate you already run. The customer who paid for a fresh slab wants it protected, and you are the one standing on it. Both trades are already in your plan — one login, one client list, nothing more to pay. Plans are month-to-month — add a trade for the season and drop back after, right from Billing.
SideWRK for Epoxy Flooring →Add masonry — the slab and the wall, same truck.
The customer who calls about a cracked driveway points at the crumbling steps and the chimney on the way out. Brick and block work bills by the square foot like your flatwork does, the big masonry outfits won't roll a truck for a patch job, and you're already parked in the driveway. Both trades are already in your plan — one login, one client list, nothing more to pay.
