Obra for Concrete and hardscape contractors

Job costing for concrete and hardscape contractors: yards, tons, hours and the pour that decides the margin

Expense tracking for concrete and hardscape contractors: ready-mix by the yard, base by the ton, equipment rentals per job, and weather delays as costs you can see.

Concrete and hardscape jobs are bought in units nobody else uses: yards of ready-mix, tons of base, pallets of pavers, days of a skid steer. The estimate turns those into a price. The job then turns weather, soil and an inspector into costs the estimate never saw, and the receipts for all of it arrive as delivery tickets on a dashboard.

Obra records each job's tickets as they arrive, by photo or forwarded invoice, and confirms them to the job and code. Rentals are costs per job, split when they span two. The wall that needed engineering goes into the forecast and becomes a change order the day the city says so. The page shows the job's expected margin before the last paver is set.

Tickets are receipts

The ready-mix ticket, the aggregate weigh slip, the rental agreement: each is a photo from the crew's phone to Obra's WhatsApp number, read into a draft with the amount and vendor, confirmed by a reviewer. Nobody in the field needs a login. The receipt tracking guide is the five-second habit that makes it work.

The rental line tells the truth

A skid steer at $450 a day is cheap until the rain week makes it $1,800. Recording rentals per job, with their own code, does two things: it shows the job's real cost while the rental is still running, and at year end it shows whether owning would have been cheaper. The overhead calculator handles the owning side.

Engineering, footings, and the change order

A retaining wall crosses the height where the city wants a stamped drawing. The afternoon that happens: quote the engineering and the bigger footing, add them to the forecast's remaining to spend, write the change order, get it signed, then dig. The committed costs guide explains why the forecast counts the quote before the invoice, and the change order guide gets the paper out the same day.

What Obra isn't for a concrete contractor

Not an estimator, not a scheduler, not a fleet tracker. Obra is the money on each job, from the tickets and hours the crew sends, in English and Spanish, exported cleanly to the accountant.

The change orders that eat the margin

The wall that needed engineering
A retaining wall crosses the height where the city wants a stamped drawing and a bigger footing. Engineering, rebar and an extra pour are a change order the day the inspector says so, or they're yours.
Soil that wasn't soil
Clay, an old slab, a buried stump. Extra excavation, extra base, extra haul-off and a rental extended by two days. Each is a receipt on the job and a line on a change order, or each is absorbed.
The rain week
Equipment on rent, crew on standby, concrete rescheduled with a fee. Weather isn't billable, but recording its cost on the job is how you learn what to put in the next bid.

Questions people ask

Can I track equipment rental per job?
Yes. The rental invoice is a cost on the job with its own code; a rental that spans two jobs is split when confirmed. At year end the code shows what renting cost against owning.
Ready-mix and aggregate come on delivery tickets, not receipts. Does Obra read those?
Yes. Photograph the ticket or forward the supplier's emailed invoice; Obra reads the amount, date and vendor into a draft on the job for a person to confirm.
How do I record weather delay costs?
As the real costs they produce: extended rentals, standby labor, rescheduling fees, each confirmed to the job. Obra doesn't track days; it tracks what the days cost.
Does Obra estimate by the yard or the square foot?
No. Estimate as you do now; Obra records what the job was sold for, what it cost by the ton and the hour, what was collected, and where the margin landed.
