The short version

  • Only STACK Construction Technologies has a free tier, so it costs nothing to try first.
  • Each has a real cost: Adaptive revenue-band pricing means a company with high turnover and thin margins, such as a materials-heavy trade, pays as if it were far more profitable than it is, and there is no seat-count lever to bring the cost down.; STACK Construction Technologies takeoff and Estimate is priced per user at $249 per user per month, so cost scales linearly with estimators
  • They diverge on capability: Adaptive covers AI invoice capture, STACK Construction Technologies covers Digital takeoff.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Adaptive

  • Revenue-band pricing means a company with high turnover and thin margins, such as a materials-heavy trade, pays as if it were far more profitable than it is, and there is no seat-count lever to bring the cost down.
  • Back charge handling is a recurring complaint; contractors that routinely back charge subcontractors find the workflow does not model it cleanly and end up tracking it outside the system.
  • Budget structures are rigid relative to a full construction ERP, so companies that need to restructure cost codes mid-project or run multiple budget versions hit walls.
  • The QuickBooks sync has documented gaps, and because Adaptive sits alongside rather than replaces the ledger, any sync failure produces two sets of numbers that someone has to reconcile by hand.
  • It is a young company on a month-to-month contract with a Series A behind it, which cuts both ways: easy to leave, but the buyer carries the risk that a core accounting dependency changes ownership or direction.

STACK Construction Technologies

  • Takeoff and Estimate is priced per user at $249 per user per month, so cost scales linearly with estimators
  • The full platform combining takeoff, estimating and field management starts at $298 per user per month
  • Field and project management is sold as a separate Build and Operate product starting at $49 per user per month rather than bundled with takeoff
  • The Build and Operate product offers only a two-week free trial, with the free version limited to Takeoff and Estimate

STACK costs $49 to $298 per user per month depending on the plan. Build & Operate starts at $49/user/month, Takeoff & Estimate at $249/user/month, and Full STACK Platform at $298/user/month. Pricing is quoted per-user and scales with team size.
