Where each one falls short

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

Kojo

  • Benefits depend on distributors providing electronic catalogues and pricing, and a contractor whose main supplier will not participate is left keying quotes by hand.
  • It serves speciality trade contractors; general contractors procure subcontracts rather than materials and get almost nothing from it.
  • Enterprise resource planning integration quality varies by system and version, so confirm the depth for your exact configuration rather than accepting the logo on the website.
  • Field adoption is the whole game, and foremen who lose signal in a plant room or basement revert to phoning the office within days unless offline capture genuinely works.
  • It changes purchasing process as well as software, so contractors whose buying authority is informal have to formalise who can commit money before the system produces clean data.

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

Kojo: Is this for general contractors?

No. It is built for speciality trade contractors buying materials. General contractors procure subcontracts and would get little from it.

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.

Source
Kojo: What if our suppliers will not connect?

You lose most of the quoting benefit and keep only the internal workflow. Check distributor participation before purchase, because it determines the return.

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
Kojo: Does it work without signal on site?

Field requests are designed for site use, and offline behaviour should be tested with your own crews in your worst locations, because that is where adoption is won or lost.

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
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.
