Here's a uncomfortable truth: the average restaurant wastes 4–10% of purchased food before it ever reaches a customer. That's not a rounding error — for a restaurant spending Rp 50 million/month on ingredients, that's Rp 2–5 million going straight to the bin. Every single month.
Poor inventory management is one of the top 3 reasons restaurants fail. The good news? It's also one of the most fixable.
Why Inventory Management Matters
Cash flow protection — Over-ordering ties up cash in stock that might spoil before use
Waste reduction — Expired ingredients, over-prepped items, and spoilage are silent killers
Theft detection — If 50 chicken breasts came in but only 40 can be accounted for, you have a problem
Never run out — 86'ing your signature dish during Saturday dinner service is devastating
Accurate food cost — You can't price your menu correctly if you don't know what ingredients actually cost
Key Concepts You Must Know
Par Level
The minimum quantity of each ingredient you must have on hand. When stock drops below par, it's time to reorder. Calculate par levels using:
Par Level = (Average Daily Usage × Lead Time in Days) + Safety Stock
Example: You use 5kg of chicken daily, your supplier takes 2 days to deliver, and you want 1 day of safety stock. Par level = (5 × 2) + 5 = 15kg.
FIFO (First In, First Out)
The golden rule of food storage. Always use older stock before newer stock. When deliveries arrive, place new items behind existing inventory. Label everything with the received date using masking tape and a marker — low-tech but effective.
Weighted Average Cost (WAC)
When ingredient prices fluctuate (and they always do), WAC gives you a fair valuation by averaging the cost of existing stock with new purchases. It's more accurate than simply using the latest invoice price.
How to Do a Proper Inventory Count
Schedule consistently — Same day, same time, every week. Sunday morning before the week starts is common
Walk the same path — Count in the same order every time: walk-in → dry storage → bar → prep area
Use a digital tool — Never count from memory. A spreadsheet works; integrated inventory software is better
Two-person verify — Have two people count independently, then compare. Discrepancies reveal either counting errors or shrinkage
Record quantity AND value — "3 bags of flour" is useful. "3 bags × Rp 45,000 = Rp 135,000" is actionable
Red Flags That You Need Software
If any of these hit close to home, it's time to move beyond clipboards:
Spending 2+ hours/week on manual counting
Food cost percentage consistently above industry benchmarks
Items run out unexpectedly at least twice a month
You can't answer "which menu item has the best profit margin?" in under 10 seconds
You have multiple locations with no centralized view
Modern inventory tools like Makan integrate directly with your POS — when an item sells, stock is automatically deducted. When stock hits par level, you get an instant alert. No more guessing, no more surprise stockouts.
