ProJobCalc vs. CoConstruct.

Contractors searching for CoConstruct because someone recommended it years ago — but who actually want a simpler, cheaper, bidding-focused tool rather than full construction management.

Competitor
CoConstruct
merged into Buildertrend in 2022 (~$499/mo)

Construction-management platform for custom-home builders and remodelers. Merged with Buildertrend in 2022 — the brand still gets searched, the product now lives under the Buildertrend umbrella.

ProJobCalc
ProJobCalc
Free · Pro $19/mo · Agency $49/mo

AI proposal generator + voice estimator + 40+ free trade calculators. Built for the solo contractor and small-shop bidding workflow.

Where CoConstruct is stronger.

  • Multi-phase project management with selections, schedules, change orders, and warranty tracking for ground-up custom builds.
  • Sub-contractor coordination across long-running jobs.
  • Mature client-facing portal for design selections (cabinets, fixtures, finishes).
  • Integrated with QuickBooks for full-build accounting.

If any of these is the load-bearing reason you’d buy this software, CoConstruct is probably the right tool. We’d rather you use what fits.

Where ProJobCalc is stronger.

  • Built for the proposal-and-quote phase that comes before the build, priced at $19/mo instead of $499/mo.
  • AI proposal generator and voice estimator — neither tool has equivalents in CoConstruct/Buildertrend.
  • No implementation, no onboarding fee, no 6-month learning curve.
  • Free tier with 40+ calculators — CoConstruct/Buildertrend has no free path.

Common questions.

I was looking for CoConstruct specifically — is it still a separate product?
No. CoConstruct merged with Buildertrend in 2022 and the combined product is sold as Buildertrend. If you were looking at CoConstruct for the design-selections workflow, that lives in Buildertrend now. If you were looking at it because someone said 'it's like Buildertrend but for smaller builders' — that distinction is gone.
I'm a custom-home builder. Buildertrend or ProJobCalc?
Buildertrend if you need real construction management: daily logs, schedules, selections, sub coordination across long builds. ProJobCalc if your pain point is 'writing proposals is killing my evenings' and you handle the actual build management with paper/Word/calendar.
Can I use both?
Plenty of shops do: ProJobCalc for the bid → win → proposal layer (because the AI generator is genuinely faster), then Buildertrend for the run. Manual handoff today; exports and the public /integrations contract make the connection easier to plan.

Try ProJobCalc before you decide.

The free tier is real — 40+ trade calculators, unlimited estimates, up to 5 saved. No card to enter, no trial countdown. If you want the AI proposal generator + voice estimator, Pro is $19/mo with a 14-day trial.
