Per-Trade vs Per-Seat
Takeoff Pricing

How per-seat pricing works

Per-seat licensing is the default across most established takeoff platforms. You purchase a named-user license for each person who needs access, and that fee recurs annually regardless of how much or how little each seat is used. Because cost ties directly to headcount, it compounds quickly as estimating teams grow.

According to MeltPlan’s 2026 benchmarks, per-seat takeoff tools commonly run $1,700–$3,500 per seat per year. STACK Pro sits in the $2,499–$2,999 range per seat annually; On-Screen Takeoff runs around $3,500 per seat per year. A three-person team on any of these tools lands between $5,100 and $10,500 a year before add-ons. The predictable result: teams share logins to avoid paying for an extra seat, or delay onboarding a new estimator because the license cost is hard to justify against uncertain project volume.

How per-trade pricing works

Per-trade pricing decouples cost from headcount. Instead of paying per user per year, you pay per trade per plan set. Pilars charges $100 per trade per plan with no per-seat fees. A three-trade project costs $300 regardless of whether one estimator runs it or five are reviewing it simultaneously. If the team grows from two estimators to six, the cost for that same set stays at $300.

One underappreciated benefit: login sharing disappears as a cost-avoidance behavior. With no per-seat fee, there is no financial incentive to crowd three people onto one account. Project managers, owners, and field leads can access the takeoff without the firm incurring additional license costs, which tends to improve review quality and reduce errors between estimating and execution.

• Pilars: $100 per trade per plan, no per-seat fees
• Whole-team access with no login-sharing incentive
• Cost scales with project scope, not with headcount

The legacy-license complication

A third pricing shape catches many estimators off guard: the perpetual license migrating to a subscription. PlanSwift’s 2025 move from perpetual licenses to a roughly $1,749-per-year subscription drew significant backlash (Bidi, 2026). Users who had paid a one-time fee expected to continue using the software indefinitely; instead they found themselves on an annual billing cycle without a meaningful change to the product.

Perpetual licenses are not free to own either. Most carry annual maintenance fees of roughly $400 per year to stay on current versions. That fee converts what looks like a one-time purchase into an ongoing obligation — and it is easy to overlook when comparing headline rates. The pricing model at purchase is not necessarily the one you will face in year three.

• PlanSwift: perpetual to ~$1,749/yr subscription (2025), widespread user backlash
• Perpetual tools often carry ~$400/yr maintenance fees regardless
• Subscription migrations can change your cost without changing the product

Where the models cross over

For a single estimator running one trade on a single plan, per-seat and per-trade pricing can look roughly equivalent. At $100 per trade, Pilars and a $1,800 annual per-seat license look comparable if that estimator runs fewer than eighteen plans a year. The economics shift decisively once you add people or volume.

Multiple estimators are where per-seat cost multiplies fastest. Add a second seat at $2,500 and you’re at $5,000 before running a single plan. On per-trade, a second estimator costs nothing extra. Multi-trade GC work adds another dimension: when the same plan covers electrical, plumbing, mechanical, and structural, compare trades-per-set against seats rather than just headline price. Four trades on Pilars cost $400 per plan regardless of how many people touch it.

• One estimator, one trade: models can look similar at low plan volume
• Multiple estimators: per-seat multiplies; per-trade does not
• Multi-trade GC work: compare trades-per-set against seats, not just headline price

Hidden costs to check on either model

Both pricing structures carry line items that do not appear in the headline rate. On perpetual and legacy tools, annual maintenance fees are the most common omission. At around $400 per year per seat, a five-seat shop pays $2,000 annually just to stay on supported software versions before anyone runs a takeoff.

Many lower-cost tools impose project or page caps that only surface during active use. A tool at a low monthly rate may limit you to twenty active projects or five hundred pages per month; exceeding those caps triggers overage charges or forces an upgrade. Collaboration features and integrations are often sold as add-ons rather than included in the base rate. The listed per-seat price may be the floor, not the ceiling — sum the base license, maintenance, and module fees to see your actual total.

• Maintenance and support fees on perpetual licenses (~$400/yr per seat)
• Project or page caps on cheaper and free tiers
• Add-on charges for collaboration features or extra integrations
