Executive Summary

About 2 million subcontractor businesses today rely on paper sheets, text messages and clubbed-together spreadsheets to track crew hours, leading to routine payroll errors, delayed approvals and leaky margins that are especially painful when labor and material costs are rising. Field supervisors and office accountants both pay the price: supervisors struggle to get verified time from crews working offline, and office teams spend hours reconciling entries and chasing approvals before payroll and job costing close. You could build a mobile-first time capture and approval workflow that works offline, stamps GPS/photo verification, lets supervisors queue approvals with one tap, and syncs to payroll and project-accounting systems through partner APIs. Targeting a $3,000 average customer lifetime value across 2 million subcontractors implies a $6.0B serviceable market, and the opportunity is supported by an 88/100 market score and a strong 84/100 revenue potential. This is an attractive moment: crews already carry smartphones and expect crew-friendly apps, margin pressure makes contractors willing to pay for accuracy, and vendors in payroll and accounting increasingly expose integrations that amplify retention. To stand out you must nail low-friction UX for nontechnical crews, offline reliability, prioritized integrations with the top 5 payroll and job-costing platforms, and a go-to-market that minimizes CAC for small firms; realistic challenges include building trust for payroll-grade data, handling jurisdictional compliance, and competing with mid-market vendors that already bundle time tracking.

Market Opportunity

Streamline subcontractor time tracking and approvals with mobile-first workflow targets a $6.0B = 2M subcontractor businesses × $3K ACV total addressable market with medium saturation and a year-over-year growth rate of 8% CAGR — construction technology and field data adoption growing as reported by industry analyses (Dodge Data & Analytics; McKinsey estimates of construction digitization).

Key trends driving demand: Mobile-first field tools — crews increasingly use smartphones and tablets on site, creating an opportunity for offline-capable time capture apps.; Pressure on margins — rising material and labor costs push subcontractors to tighten control over labor hours and approvals, increasing willingness to pay for time accuracy.; Integration-first ecosystems — payroll and project accounting vendors publish APIs and partner programs, making integrations a primary value driver for time-tracking startups.; AI-assisted data validation — lightweight AI models can flag anomalies and auto-fill repetitive entries, reducing admin time and dispute resolution costs..

Key competitors include Rhumbix, ClockShark, Procore (Time & Workforce modules).
