Short answer: what is drywall takeoff software?

Drywall takeoff software lets a drywall contractor measure quantities directly off a PDF plan set instead of a paper scale rule and a spreadsheet. ExitSaaS builds a browser-based takeoff and estimating tool that imports multi-page plan sets, calibrates scale per sheet, and measures square feet of board on walls and ceilings, linear feet of tape and bead. One trace drives a full material and labor assembly with coverage rates and waste built in, and every quantity traces back to a colored mark on a specific sheet. It costs $2,500 one time, and you receive the source code under a perpetual licence — so there is no renewal, no seat count, and no year-two invoice.

The problem: board is ordered in sheets, not square feet

  • Square footage is what you measure; 4x8, 4x10 and 4x12 sheets are what you buy, and the best sheet length changes with ceiling height.
  • Openings have to come out of the wall they sit in, not off the job total, or the deduction lands on the wrong condition.
  • Walls and ceilings take different board, different finish levels and different production rates — but they are on the same plan.
  • Tape and bead are linear, driven by the same wall lines you just measured for area, plus every inside and outside corner.

Counting sheets off a plan by hand is slow and it is the first thing to go wrong when a drawing is revised. One moved wall changes board, tape, bead, screws, compound and hours at the same time.

How the tool handles it

A wall condition gives square footage from one trace, converts it to sheet count at the sheet length you specify, and subtracts each opening from its parent wall. Tape and bead come off the same geometry, and inside and outside corner counts are derived from the traced polyline rather than tallied by hand.

One trace, the whole material list

A condition is a named, colored layer you trace on the drawing. An assembly turns that one condition into every part it drives, each with its own formula, coverage rate, waste percentage and rounding rule. A 1/2in board, level 4 finish condition looks like this:

Part Unit Driven by
Gypsum boardSHEETwall SF ÷ sheet coverage, + 10% waste, rounded up
Joint tapeLFseam LF from board layout + corner LF
Joint compoundGALboard SF ÷ coverage per gallon
Corner beadLFoutside corner LF — wall corners, jamb returns, soffits, bulkheads and columns
L-bead / J-beadLFtermination LF at finished edges
Control joint beadLFrun LF ÷ joint interval
Bead fastenersEAbead LF ÷ spacing
ScrewsLBboard SF × fasteners per SF ÷ screws per pound, rounded to the box
Hang laborHRboard SF ÷ hanging production rate
Tape and finish laborHRboard SF ÷ finishing production rate

Change a coverage rate, a waste percentage or a unit cost and every job using that assembly re-prices. You are not editing numbers in twelve places.

Openings deduct from their parent wall

A door or window is a deduction tied to the wall it sits in, so the square footage that drops is the square footage of that specific condition.

Walls and ceilings priced separately

Different board, different finish level, different production rate — traced as separate conditions on the same sheet so the labor hours are honest.

Bead comes from every outside edge, not just wall corners

Corner bead runs at wall corners, and also at door and window jamb returns, soffits, bulkheads, dropped ceiling perimeters and columns. Counting only full-height wall corners can leave you a third short on a house with soffits.

Every number traces back to a mark

When the sheet count is short on a Friday, you can see exactly which walls were traced, what sheet length was assumed, and which openings were deducted. The answer is on the drawing, not in someone's memory.

Every number on the report links back to a specific mark, on a specific sheet, at a specific place on the page. The marked-up PDF export draws every mark in its condition color with the quantity labeled — that is the file you attach to the bid.

Accuracy is held to a stated tolerance: linear measurements within 0.10% of true, straight-sided areas within 0.25%, and calibration repeatable within 0.20% across five separate calibrations of the same page. Geometry is stored in PDF units, never screen pixels, and rounding happens exactly once — at report time.

What it costs

A second delivery run to the supply house, priced honestly against the hours it burns, is most of what this tool costs.

$2,500, paid once. Nothing in year two. Nothing in year three. No per-seat bill and no renewal date.

Estimators using it A per-seat subscription, five years Ours, one-time licence
1$8,745 – $10,000$2,500
2$17,490 – $20,000$2,500
3$26,235 – $30,000$2,500
5$43,725 – $50,000$2,500

Their column multiplies by headcount and then repeats every year. Ours does neither. Put a fourth estimator on it and the number is still $2,500, because you are not licensing seats — you are buying the software.

And it does not repeat

Year 1$1,749 – $2,000 × seats$2,500
Year 2$1,749 – $2,000 × seats$0

What you actually receive

  • The source code. Not access to it — a copy of it, running on your infrastructure.
  • A one-time perpetual licence. It does not expire, it cannot be revoked, and there is no renewal date in your calendar.
  • No seat count. Put every estimator in the company on it. There is no user tier to outgrow and nothing that counts logins.
  • No dependence on us. Sixty days of support are included. After that you can hire any developer to change it, because you have the code. Most vendors cannot make that offer, because with them you are renting.

Subscription figures are publicly reported PlanSwift prices from software review sites, shown as a representative example of per-seat takeoff pricing. Check any vendor's current pricing directly before you compare. See the full PlanSwift comparison.

What is being built next

  • DXF and DWG import is in active development. Today the tool reads PDF. If your drawings arrive as CAD files, ask on the call and we will give you honest timing rather than a guess on a web page.
  • Auto-count symbol recognition — box a symbol once and find every match on the sheet — is a later release.
  • Multi-estimator assignment, so a supervisor can hand work to specific people, is still being built out.

See it run on your own plan set.

Bring a PDF you have already bid. We will take it off live on a 30-minute call and you can check our numbers against yours. $2,500 one time. Nothing in year two.

Frequently Asked Questions

Yes. Set the sheet size you buy — 4x8, 4x10, 4x12 — and board square footage converts to a sheet count with your waste percentage applied and the result rounded up. Change the sheet length and the count updates.

As deductions attached to the wall they sit in. The square footage comes off that specific wall condition rather than off a job total, which keeps each room's board count and labor hours correct.

Yes. Trace them as separate conditions with their own board type, finish level and production rate. They show in different colors on the marked-up plan and produce separate labor lines.

Both. Tape linear feet come from the seam and corner geometry. Corner bead comes from every outside edge in the trace — wall corners at full height, plus jamb returns, soffits, bulkheads and columns, which are the ones hand counts miss — and it rounds to the stick.

Yes — level 4 in the living space and level 2 in the garage are two conditions with different compound coverage and different finishing production rates, traced on the same drawing.

$2,500 once. $0 in year two and $0 every year after. It is not a subscription — it is a one-time perpetual licence, and you receive the source code and run it on your own infrastructure. Sixty days of support are included after launch. For comparison, PlanSwift is now sold as an annual subscription reported at roughly $1,749 to $2,000 per seat per year, which comes due again every twelve months and again for every estimator you add.

Everyone in your company. There is no seat count, no user tier and nothing that counts logins, because you are not licensing access — you are buying the software. Adding a fourth or a tenth estimator does not change the price. This is the whole difference between owning a tool and renting one per head.

Yes. You receive the source code under a perpetual licence and it runs on your own infrastructure. That is what makes the licence meaningful: after the included 60 days of support you can hire any developer to change it, and nothing we do afterwards can switch it off or raise its price.

Yes. It runs in the browser, so it works on Windows, Mac, iPad and Android tablets with no install and no virtual machine. Pen and touch input share the same code path as the mouse, so tracing with a stylus behaves the way tracing with a mouse does.

Linear measurements land within 0.10% of true value, straight-sided areas within 0.25%, and calibration repeats within 0.20% across five independent calibrations of the same page. Geometry is stored in PDF units at full precision — screen pixels never touch the database — and rounding happens once, at report generation.

Not yet — DXF and DWG import is in active development. Today the tool reads PDF plan sets, which is how drawings almost always arrive. If CAD files are how your work comes to you, raise it on the call and we will give you honest timing instead of a promise on a web page.
