Where each one falls short

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

Foundation Software

  • No pricing is published anywhere, so shortlisting requires sitting through a sales process before you know whether the product is within budget at all.
  • Implementation, data conversion and training are billed separately from the licence and routinely run into five figures, which buyers comparing monthly software subscriptions do not budget for.
  • The payroll compliance engine is built for United States federal and state law, so the product has essentially no value to contractors outside the US.
  • The interface is a long-lived Windows-style application, and staff hired from cloud-native tools find it slow to learn compared with Buildertrend or Procore.
  • Project management, document control and field collaboration are weaker than the dedicated construction platforms, so most sites end up running Foundation for money and something else for the job, and paying twice.

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
