The short version

  • Only STACK Construction Technologies has a free tier, so it costs nothing to try first.
  • Each has a real cost: HCSS HeavyBid pricing is quoted per estimator seat with modules layered on top, so a firm comparing it against a published per-user product cannot make a like-for-like comparison until it has a proposal in hand.; 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: HCSS HeavyBid covers Crew and production rate estimating, 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.

HCSS HeavyBid

  • Pricing is quoted per estimator seat with modules layered on top, so a firm comparing it against a published per-user product cannot make a like-for-like comparison until it has a proposal in hand.
  • The crew and production rate model suits self-performed civil work and fights you on vertical building estimates where most cost sits in subcontractor quotes, which pushes mixed contractors into running two estimating systems.
  • Historical cost databases built up over years are the reason firms stay, and there is no clean export of that structure into a competitor, so the switching cost grows every year you use it.
  • The Windows client is where the mature functionality still lives and the web version has been rolling out gradually, so a firm buying for browser access should confirm which specific modules it needs are actually available there.
  • Getting value depends on disciplined field cost coding flowing back from HeavyJob; contractors that do not close that loop end up estimating from vendor-supplied rates and get little more than a spreadsheet with better import filters.

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

Answered from the vendors’ own pages

HCSS HeavyBid: Does HCSS publish HeavyBid pricing?

No. HCSS quotes per company based on estimator seats, modules and implementation. Third-party figures circulating around four thousand dollars a year describe a single-estimator entry point, not a team.

STACK Construction Technologies: How much does STACK Construction cost?

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.

HCSS HeavyBid: Can HeavyBid estimate building work?

It can, but poorly compared with its civil strength. If most of your cost is subcontractor quotes rather than self-performed crew production, a takeoff-led estimating tool fits better.

STACK Construction Technologies: Does STACK offer free options?

Yes, Takeoff & Estimate includes a free version, and Build & Operate includes a two-week free trial. Full STACK Platform offers a Build Your Price option for custom configurations.

Source
HCSS HeavyBid: Do I need HeavyJob as well?

No, but the estimate-to-field-cost loop is the main argument for HCSS as a suite. HeavyBid alone is just an estimating tool.

STACK Construction Technologies: Can I get custom pricing from STACK?

Yes, STACK offers a Build Your Price option for the Full STACK Platform and Takeoff & Estimate to accommodate specific business requirements. Custom pricing requires direct consultation with their sales team.

Source
HCSS HeavyBid: Is there a perpetual licence?

HCSS sells subscription licensing. Older perpetual arrangements exist in the installed base but new buyers should expect an annual contract.

STACK Construction Technologies: How quickly can STACK be implemented?

STACK promises quick implementation measured in hours rather than weeks, though the exact timeframe depends on your configuration and team size.
