Monthly P&L tells you what happened. Weekly P&L tells you what's happening. The difference is 3-4 weeks of margin bleed before you can react. Here are the six lines every restaurant owner should review every Monday — and what the monthly close misses.
Why weekly beats monthly
- Food cost spikes — onion, tomato, chicken price moves show up in week 1-2 purchases. Monthly P&L averages them across 4 weeks.
- Labour overruns — overtime, extra shift, agency labour added mid-month. Weekly catches it before it compounds.
- Aggregator settlement lag — T+7 to T+14 settlement means last week's revenue hits this week's bank. Weekly reconciliation prevents cash surprises.
- Covers trend — a 15% week-on-week covers drop is invisible in monthly averages until month-end.
The six weekly lines
| Line | Source | Target / alert |
|---|---|---|
| Gross revenue | POS daily close | Track vs same week last month |
| Food cost % | Purchase invoices ÷ revenue | Within 2 points of recipe theoretical |
| Labour cost % | Payroll ÷ revenue | Within format ceiling (see prime cost post) |
| Aggregator net settlement | Platform CSV | Match POS aggregator channel revenue |
| Cash position | Bank balance | Cover next 2 weeks fixed costs |
| Covers / AOV | POS | Flag if covers drop >10% WoW |
The Monday 20-minute ritual
- Pull POS revenue — last 7 days, split dine-in vs aggregator.
- Pull purchase total — vendor invoices + cash market buys. Divide by revenue for food cost %.
- Check payroll — actual hours vs roster. Flag overtime >5% of labour.
- Reconcile aggregator — settlement received vs POS aggregator revenue. Gap >3% means refunds or pending.
- Note one action — if any line is red, write one fix for this week. Not three; one.
What to leave for monthly
Rent, EMI, insurance, licence renewals, depreciation, and owner draw belong in monthly P&L — they don't move week to week. GST reconciliation, vendor payment scheduling, and full roster review are monthly tasks. Weekly is for the variable lines that kill you if ignored.

A simple spreadsheet with 6 rows and 4 weekly columns is enough. You don't need accounting software for weekly tracking — you need discipline. The restaurants that survive year one review this every Monday without exception.
