Case Study: Replacing 3 spreadsheets with one dashboard, saving ~6 hrs/week in admin overhead.
Small businesses and founders in India manage HR through 3–5 separate spreadsheets — attendance in one file, payroll in another, petty cash in a third, field visits in WhatsApp messages. Every month, reconciling these takes 6+ hours of admin time and still produces errors. There's no single view of what's happening with the team.
BACKOFFICE OS v2.0 — a single-file, zero-dependency HTML dashboard that replaces all of it:
- Attendance Tracking — Clock In/Out, break deduction, live status
- Leave Management — Apply, approve, reject with leave wallet per employee
- Payroll — Salary config, auto-calculate, payslip generation, payout queue
- Expense Claims — Submit, review, and approve with audit trail
- Field Visit Logs — Location, mode, hours, and expenses for on-ground staff
- Petty Cash Ledger — Float tracking, category breakdown, voucher log
- HR Admin Panel — Employee management, payroll cycles, leave policy config
No install. No database. Open the file in a browser and it works.
