The verdict in three sentences
For a 120-employee general contractor in New York, Procore is priced on annual construction volume and typically runs $15,000 to $60,000 a year for a firm this size, while lighter tools such as Fieldwire or Raken cost $40 to $90 per user per month. A custom field app with offline mode typically costs $50,000 to $120,000 from a US agency (2026 ballpark), delivered in 3 to 5 months. The core gain is 4 to 6 hours a week per superintendent or project manager, provided the tool is used on site, not at night in the trailer.
What a superintendent loses every week
A superintendent running 3 to 5 jobs writes daily reports in a notebook or spreadsheet, shoots photos on a personal phone, copies punch items from meeting minutes and collects crew hours on paper timesheets. On Friday everything is rebuilt for payroll, certified payroll on public jobs, and the monthly pay application.
Punch lists and safety records are the sensitive part: in New York City, Department of Buildings inspections and Local Law 196 site safety training records must be produced on demand, and a poorly tracked punch item can hold retainage, usually 5 to 10% of the contract, for months.
| Weekly task | Time today per superintendent | With a field app (2026 estimate) |
|---|---|---|
| Daily reports (weather, manpower, progress) | 3 to 4 h | 1 h, entered on site with photos |
| Punch list management | 2 to 3 h | 0.5 to 1 h, items pinned on drawings |
| Crew hours collection | 1.5 to 2 h | 0.5 h, mobile timecards by foremen |
| Meeting minutes | 1.5 h | 0.5 h, generated automatically |
| Finding documents and drawings | 1 h | 0.2 h, current set on tablet |
| Total | 9 to 11.5 h | 2.7 to 3.7 h, so 4 to 6 net hours saved after adoption |
Procore or custom: the comparison
Procore is the market reference and covers almost everything, at a price tied to your volume. Limits appear when you need your exact owner report formats, deep links to your payroll and accounting stack (Sage 300 CRE, Foundation, Viewpoint), union-specific timecard rules, or days of work in basements with no signal.
| Criterion | Procore or similar | Custom (US agency) |
|---|---|---|
| Upfront cost | $0 to $10,000 implementation | $50,000 to $120,000 |
| Recurring cost | $15,000 to $60,000 a year, volume-based | Maintenance and hosting, 10 to 15% of build per year |
| Time to go live | 4 to 10 weeks | 3 to 5 months |
| Offline mode | Partial, varies by module | Designed in from day one, deferred sync |
| Payroll and accounting link | Standard integrations | Certified payroll export, Sage 300 CRE or Foundation link |
| Report formats | Vendor templates | Exact formats of your owners and architects |
| 5-year cost (median scenario) | About $175,000 | About $120,000 to $135,000 |
Median scenario: $35,000 a year for Procore at this volume ($175,000 over 5 years) against an $85,000 build and $10,000 a year of maintenance. If your volume grows, the gap widens.
Kolonell prices custom applications on a fixed grid in FCFA and EUR: an offline field app falls into our medium tier, 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR), or complex tier, 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR) with payroll and ERP connectors. Maintenance runs 35,000, 75,000 or 120,000 FCFA a month (53, 114 or 183 EUR). Exact scope is set in the quote.

Over 46 weeks that is 1,840 hours. At a loaded $95 an hour for a superintendent, the gain reaches $174,800 a year. Add one avoided punch dispute a year at $15,000 and the total exceeds $189,000.
With an $85,000 build and $10,000 maintenance, payback comes in under 6 months, even counting only half the hours saved.
FAQ
Does the app work in a basement with no signal?
Yes, if it is built offline-first: data is stored on the tablet and syncs when signal returns. Budget $500 to $1,100 per rugged tablet.
Will foremen really fill in timecards on mobile?
Yes if it takes under a minute per crew. In practice 80 to 90% of foremen adopt it within 4 to 6 weeks with on-site coaching.
Can we send reports to owners?
The app produces PDFs in each owner's format with timestamped photos. A read-only link can also be shared with the architect.
Do we have to change payroll software?
No. An export of hours to your payroll or ERP, including certified payroll fields, typically costs $4,000 to $10,000 within a custom project.
How fast can a pilot job start?
A reports and punch list module can run on 2 pilot jobs within 8 to 10 weeks, with timecards and connectors following within 2 months.
