Honest comparison
ProJobCalc vs. Knowify.
Contractors who haven't yet outgrown the proposal → bill cycle into multi-phase progress billing. If you don't draw AIA progress payments on long jobs, Knowify's biggest advantage doesn't apply to you.
Construction-management platform built for small contractors (2-50 employees). Strong on time tracking, job costing, AIA progress billing, and QuickBooks integration.
AI proposal generator + voice estimator + 40+ free trade calculators. Built for the solo contractor and small-shop bidding workflow.
Where Knowify is stronger.
- AIA progress billing for long-running jobs (G702/G703 forms).
- Time tracking + job costing for W-2 employees on multi-week builds.
- Bi-directional QuickBooks Online + Desktop sync, mature.
- Sub-contractor management with lien-waiver tracking.
If any of these is the load-bearing reason you’d buy this software, Knowify is probably the right tool. We’d rather you use what fits.
Where ProJobCalc is stronger.
- AI proposal generator vs. Knowify's manual estimate builder.
- Voice estimator for field-walked jobs.
- Cheaper for solo operators: $19/mo vs $99/mo entry.
- Built for the proposal layer, not full job costing — if your jobs run days/weeks (not months), Knowify's complexity is overhead.
- 40+ free trade calculators with no setup.
