TakumiCloud — the construction-business cloud that unifies everything from on-site attendance to payroll and billing

On-site staff clock in by smartphone; the office totals automatically. Attendance through payroll, costing, and billing—all in one cloud.

Takara Komuten Group — On-site workers enter clock-in/out and photo daily reports on their smartphones, and everything from attendance totaling, payroll (with allowances/insurance), per-site costing, and billing to the revenue dashboard is linked automatically. We built a new multi-tenant business platform that eliminates the office's manual totaling and double entry.

Challenge
Before

On-site attendance arrived scattered across paper and chat, and the office totaled it by hand in Excel. Payroll—including each worker's allowances and insurance—depended on specific individuals, and per-site profitability was never visible in real time.

  • We want to collect on-site attendance and reports accurately by smartphone, not on paper or chat
    Manual paper & Excel totaling effort
  • We want each worker's pay, allowances, and insurance calculated automatically, without errors
    Payroll dependent on individuals + calculation errors
  • We want to grasp each site's costs and revenue in real time
    Lack of profitability visibility
  • Attendance, payroll, and billing are split across disconnected tools
    Double entry & transcription errors
