Short answer: what is acoustical ceiling takeoff software?

Acoustical ceiling takeoff software lets a acoustical 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 ceiling area, linear feet of perimeter wall angle. 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: grid does not scale with area the way tile does

  • Over the same 1,000 square feet a 2x4 ceiling takes about 125 four-foot cross tees. A 2x2 takes those same 125 plus another 125 two-foot tees, and doubles the tile from 125 panels to 250. Main runner quantity does not move at all.
  • The perimeter is a second, independent quantity. A 40 by 25 room and a 100 by 10 room are both 1,000 square feet, with 130 and 220 feet of perimeter. The narrow one needs about seventy percent more wall angle and far more cut tile.
  • Every device on the reflected ceiling plan displaces a tile and may demand its own support, with the obligation set by weight — one safety wire, two, or hung directly from the structure.
  • Hanger count comes from the plan and hanger length comes from the section. Plenum depth is never shown on the reflected ceiling plan, so it is possible to get the count exactly right and the footage badly wrong.

Carton coverage will not save you either. Across two manufacturers the same nominal tile ships at 48, 56, 64, 80, 96 and 112 square feet per carton, and the carton is usually the minimum buy.

How the tool handles it

Trace the ceiling, pick 2x2 or 2x4, and the system lays the actual grid — mains at four feet on centre, four-foot tees at two feet, and two-foot tees only where the module calls for them. Piece counts come from that layout, so switching a room from 2x4 to 2x2 changes the tee and tile counts correctly in one move. Each region carries its own perimeter and its own height, so a change in ceiling height starts a new region rather than extending the old one.

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 2x2 lay-in ceiling condition looks like this:

Part Unit Driven by
Main runnerLF / CARTONarea SF ÷ 4 = LF; mains at 4ft o.c. — 25 LF per 100 SF
4ft cross teeEAarea SF ÷ 8 pieces — 12.5 per 100 SF, same in 2x2 and 2x4
2ft cross teeEAarea SF ÷ 8 pieces in a 2x2 module, zero in a 2x4
Wall angleLFregion perimeter, summed over every region including soffits
Wall angle fastenersEA0.75 × perimeter LF at 16in o.c., plus 2 per stick end
Ceiling tileCARTONarea ÷ 4 (2x2) or ÷ 8 (2x4) pieces, ÷ SF per carton for that item
Hanger wireEAarea SF ÷ 16, one per 16 SF; length = plenum depth + 12in for wraps
Fixture support wiresEAby fixture weight — one wire, two, or direct to structure
Seismic bracingASSEMBLYSeismic Design Categories D/E/F only — bracing above 1000 SF, separation joint above 2500 SF
Install laborHRarea SF ÷ production rate by module
Hanger-wire attachment hardwareEAone per hanger wire — eye lag, shot pin or deck anchor

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.

The module changes the tees, not the mains

Mains run at four feet on centre in both 2x2 and 2x4. The only difference is a two-foot tee bisecting every four-foot bay — which doubles the tee pieces and the connections while the main count stays put.

Perimeter is a first-class quantity

Wall angle, molding fasteners, terminal-end support wires and border waste all come off the traced perimeter, so a long corridor prices differently from a square room of the same area. It is a different job.

Waste follows shape, not a flat percentage

A published environmental declaration used a seven percent installation waste factor. Border waste scales with perimeter over area, so a corridor at 0.22 generates far more cut edge per square foot than a room at 0.13. Tegular panels raise it again, since every cut border tile is field-routed or its edge painted.

Every number traces back to a mark

When a grid order is questioned, the takeoff shows each region traced at its own height with its module, perimeter and fixture count labeled, so the piece counts can be traced back to the layout that produced them.

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 ceiling ordered as 2x4 and built as 2x2 is short 125 tees and 125 panels per thousand square feet. That is a second delivery and a stalled crew.

$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

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.

Frequently Asked Questions

For a 2x4 layout: 25 linear feet of main runner and 50 feet of four-foot cross tee, which is 12.5 pieces. For 2x2: the same mains and four-foot tees, plus 25 feet of two-foot cross tee, another 12.5 pieces. Those come straight out of the geometry — mains at four feet on centre, cross tees at two.

Yes, and the gap is in the tees and the tile, not the mains. Main quantity is identical because mains stay at four feet on centre either way. But 2x2 adds a two-foot tee in every eight square foot bay and doubles the tile, so over 1,000 square feet you go from about 125 tee pieces to 250 and from 125 panels to 250.

One per 16 square feet, because hangers sit at four feet on centre along mains that are themselves at four feet. In Seismic Design Categories D, E and F, ASTM E580 additionally requires each terminal runner end supported within eight inches of the wall; elsewhere that is good practice rather than code. Length is plenum depth plus roughly twelve inches for the required wraps, and plenum depth comes off the section, not the reflected ceiling plan.

A published environmental declaration for one manufacturer's panels used a seven percent installation waste factor — a reasonable starting point, though newer declarations from the same maker use lower figures. It is not a safe universal, because ceiling waste is generated at the perimeter by border cuts. A long narrow corridor has far more perimeter per square foot than a square room of the same area. Tegular panels push it higher again.

By the piece, packed in cartons, and the carton is usually the minimum buy. A twelve-foot main carton commonly holds 20 pieces and 240 feet; a four-foot cross tee carton 60 pieces and 240 feet. Wall angle is the one to watch — ten and twelve foot sticks are both standard depending on the item, and carton counts range from 10 to 50 pieces because the heavier two-inch seismic profile takes more room in the box.

$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.
