Labour & Attendance
Phase 1
Record daily attendance, compute wages, and track payment status for all workers.
📋 Daily Entry
📅 History
💰 Pay Summary
Daily Entry — How It Works
Each day, open Daily Entry, select the date (default = today), and tap each worker card to cycle their status. The app auto-calculates wages based on the worker's rate and presence.
| Field | Type | Notes |
|---|---|---|
| Status | Toggle button | Cycles: Present → Half Day → Absent |
| Block | Dropdown | Which block the worker was in (optional) |
| Activity | Dropdown | Harvesting, Weeding, Pruning, Spraying, Fertilising, Irrigation, Planting, Transport, General |
| Kg Cherry | Number | Only shown for piece-rate workers; enter kg harvested that day |
| Rate ₹/kg | Number | Default from worker profile; can be overridden per day |
| Pay Preview | Calculated | Live: Day Rate × fraction + Piece Rate × kg |
Pay Calculation Logic
| Worker Type | Formula |
|---|---|
| Day Rate only | day_rate × days_fraction |
| Piece Rate only | piece_rate × kg_cherry |
| Both | (day_rate × days_fraction) + (piece_rate × kg_cherry) |
Days fraction: Present = 1.0 · Half Day = 0.5 · Absent = 0.0
Pay Summary Tab
Shows unpaid wages per worker across all dates. Tap Mark Paid to mark all unpaid attendance records for that worker as paid. This also creates/updates a payroll_monthly record for the current month.
⚠️
You cannot navigate to a future date. The ▶ (next) button is disabled when you are on today's date.
Harvest Records
Phase 1
Log daily per-block yield by crop type and track seasonal totals.
🍒 Daily Entry

Summary Tab
Shows current season totals by crop (total kg and estimated % share), plus a bar chart of the top-producing blocks. Top 20 blocks are shown; remaining are indicated as a count.

| Gross (monthly worker) | monthly_wage |
| Gross (daily worker) | Σ total_pay from attendance, or day_rate × days + piece_rate × kg |
| PF Deduction (employee) | 12% × min(gross, ₹15,000) |
| ESI Deduction (employee) | 0.75% × gross (if gross ≤ ₹21,000) |
| Net Payable | gross − pf_emp − esi_emp |
| Employer Cost | gross + (13% × min(gross, ₹15,000)) + (3.25% × gross) |
