Built for Electrical, Plumbing, and HVAC

From the plan to the paid invoice.

C- Stack is job management for trade contractors, with plan takeoff built right in. Measure a drawing, send the quantities straight into an estimate, and carry that same job through work orders, timesheets, and the final bill — without retyping a single number.

Free for one or two people. No card required to get started.

Most job software makes you take off somewhere else.

Measure in one tool, write the numbers down, retype them into an estimate in another. Every step is a chance to fat-finger a quantity and eat the difference. C- Stack keeps takeoff and estimating in the same place.

1

Upload the plan

Drop in a plan sheet — one page or the whole set.

2

Set the scale

Click a known dimension and enter it in feet and inches.

3

Measure and count

Trace runs, drop count markers. Totals add up as you go.

4

Send to estimate

Quantities land in a new estimate, ready to price.

Everything the job touches, in one place.

Bid it, schedule it, work it, bill it. The job carries its own history the whole way through.

Takeoff on the plan

Upload a plan sheet, set the scale off a known dimension, then measure runs and count fixtures right on the drawing. Multiple pages, each with its own scale.

Estimates that build themselves

Send takeoff quantities straight into an estimate — no retyping numbers off a notepad. Approve it and convert it to an invoice in one click.

Jobs that hold everything

Every estimate, work order, and invoice stays attached to the job it belongs to, so nothing goes missing between the bid and the final bill.

Work orders for the field

Dispatch work to your techs. They see only what's assigned to them and move it through scheduled, in progress, and complete from wherever they are.

Timesheets and payroll

Crew logs hours against the job they worked. You approve them, payroll totals hours and pay by tech, and exports to CSV for your bookkeeper.

Your whole crew

Invite your people as management or technician. Technicians see their work orders and their own hours — nothing else. Seats scale with your plan.

Straightforward pricing.

Start free and move up when your crew grows. Takeoff is included on Pro and above.
