KhanaOSRunning out of milk at 9:15am on a Tuesday is not just an inconvenience. It is a revenue event. Every customer who arrives between 9:15am and whenever your delivery arrives — typically 45–90 minutes if you're lucky — either leaves or switches to a non-milk drink at a lower price point. A café doing 50 orders in the morning rush loses 30–40 of them if milk runs out. At an average ticket of ₹200, that is ₹6,000–8,000 in a single morning.
Running out mid-rush is almost always a systems failure, not bad luck. It happens because the café does not have a formal par stock level for milk, or because the daily stock count was skipped the previous evening, or because the backup supplier's number is not saved on anyone's phone. Every mid-rush stockout has a preventable root cause.
The second hidden cost of poor inventory management is wastage — ingredients purchased but not used. Industry data shows that the average coffee shop wastes 20–25% of its milk, which at Indian café scale (15–25 litres per day at ₹60–70/litre) amounts to ₹5,500–11,000 per month of milk poured down the drain.[1] Combined with pastry wastage, expired syrups, and over-ordered supplies, poor inventory management typically adds 3–5% to a café's COGS without generating a single rupee of revenue.
Average coffee shop milk wastage rate: 20–25% of total milk purchased.
A café using 20 litres/day of milk (₹65/litre): monthly milk spend ₹39,000. At 22% wastage: ₹8,580/month wasted.
