PlanProof vs Square Takeoff vs PlanSwift

Three tools, three philosophies

PlanSwift is on-screen takeoff in its classic form: you work through the sheets, click the boundaries and runs, and the software keeps the counts, lengths, and areas accurate. Square Takeoff, at a published $249/mo, is the same philosophy delivered in the browser, with assist features for the clicking. In both, the measurement judgment is yours — which is precisely what their users value about them.

PlanProof automates the measurement itself and attaches a proof status to every line of the output: proved (traced to drawn geometry at a proved scale), bounded (held between stated limits), flagged (needs review, with the reason), or refused (no number, with the precise reason one could not be measured) — plus an overlay showing where each proved quantity was measured on the drawings.

None of the three removes human work; they place it differently. Manual tools put your hours into measuring, with control at every click. Automated proved takeoff puts your hours into review, concentrated on the lines that carry flags or refusals. Everything else in this comparison follows from that placement.

Pricing, side by side

• Square Takeoff — publishes $249/mo, about $2,988 a year per seat.
• PlanSwift — licensed software; it publishes current pricing on its own site, so check there rather than trusting third-party numbers, ours included.
• PlanProof — $299–$499 per single project, $199–$299 one-time for owner-builders, and builder plans at $499–$2,499/mo by project volume.

The useful anchor is the outsourced takeoff at $200–$500 per plan set, because that is the make-or-buy alternative all three tools compete with. A builder bidding a few times a year is better served by per-project pricing than by a seat that bills through the slow months; a busy estimating desk earns a seat back easily. Around ten projects a year the annual totals converge, and the deciding cost stops being the license — it becomes the hours each takeoff takes and the checking each one needs.

Where your time goes in each tool

In PlanSwift or Square Takeoff, your hours are the takeoff. You walk the sheets, set the scale, click the wall runs and areas, read the schedules, and the software keeps the math and the organization. The output is as good as your reading of the plans that day — which is exactly the control a careful estimator wants, and the measuring pass doubles as a review pass.

In PlanProof the measuring is machine time — in our internal gauntlet across 33 real public plan sets, runs took 2s–74s per plan set — and your hours move to review: working the flagged lines, resolving or escalating the refusals, applying judgment on waste, substitutions, and pricing. That review is real work, and no honest vendor claims otherwise. The difference is where it points: at the specific lines that carry stated uncertainty, rather than spread evenly across every line you clicked.

Which placement is better depends on you. Estimators who want hands on every number already have a review built into their clicks. Builders without a full-time estimator — or estimators who would rather spend the afternoon resolving six flags than measuring forty sheets — want the review concentrated where the uncertainty lives.

Evidence and audit trail

PlanProof publishes its evidence model: every line carries a proof status, every proved quantity traces to a spot on the drawings through the proof overlay, an adversarial audit runs before any status ships, and exports are signed so a third party holding only the file can verify what was measured, what was flagged, and what was refused.

Square Takeoff and PlanSwift do not publish per-line proof status, evidence trails, or refusal behavior, and neither publishes what its exports record about where each quantity came from. That is a question to ask on a demo, not a conclusion to assume: open the export each tool produces and ask what a supplier could verify from the file alone.

The reason to care is the timeline of a bid. A quantity gets questioned weeks or months after it was measured — by a supplier pricing the package, a customer contesting a change order, a lender auditing a draw. Whoever holds the file then was not in the room when the measurement happened. The file has to answer for itself, or you do.

Residential fit

Residential plan sets make specific demands: window and door schedules that must reconcile against elevations and floor plans, framing packages built from wall runs at proved scales, and — routinely — plan-set problems: sheets that contradict each other, scale statements that are missing or wrong, raster-only pages inside an otherwise clean set.

The manual philosophy handles all of this through you. In PlanSwift or Square Takeoff, reconciling a schedule against the elevations is your process, and catching a contradiction between sheets is your read — genuine control, and also a genuine dependency on the person doing the clicking that week.

PlanProof is built for residential specifically, and plan-set problems are first-class output rather than surprises: a schedule that conflicts with the plan surfaces as a flag instead of the tool silently picking a side, and a sheet whose scale cannot be proved produces refusals with that reason, not confident numbers. In our internal gauntlet across 33 real public plan sets, 85% of plan sets were takeoff-ready and 0 do-not-bid lines shipped — the rest of the story was flags and stated refusals, which is the designed behavior on imperfect sets.

Who should pick which

• Pick PlanSwift if you want full manual control, your estimators already know an on-screen workflow, and your own process is the audit trail you trust.
• Pick Square Takeoff if you want on-screen measurement at a published flat $249/mo and are standardizing a team on one assisted-measurement workflow.
• Pick PlanProof if you build residential, bid in bursts that fit per-project pricing, and need quantities you can defend line by line — with flags and refusals pointing your review at the lines that need it.

Whichever way you lean, put one messy plan set from your own backlog through the demo and ask the same two questions of every tool: where did this number come from, and what happens when a number can’t be measured? The answers are the comparison.
