There is a cost in your restaurant that rarely appears as its own line in the accounts but is there every week: waste. Produce that spoils, prep that is never used, a "just in case" order that ends up in the bin. Every kilo thrown away is something you paid for and never sold.
The good news is that waste is one of the few costs you can cut without customers noticing anything, except perhaps fresher food. It comes down to buying closer to what you sell and moving stock through the kitchen in the right order.
Why waste hurts so much
Restaurant margins are thin, and waste comes straight out of them. Raising prices is visible and customers may push back. Reducing waste improves your margin quietly, and often improves quality at the same time, because fresher stock means better plates.
The three usual culprits
- Buying by eye. Without knowing what sells on which days, it feels safer to order extra. The extra spoils.
- Stock that sits. Products that stay too long in the store room or freezer lose quality and end up thrown away.
- Weak forecasting. Not anticipating strong and quiet days leads to too much on Monday and running out on Saturday.
The common thread is a lack of information about what you actually sell.
What stock rotation means
Stock rotation, or stock turnover, measures how many times your stock is used up and replaced in a period. A simple version:
Stock turnover = cost of food used in the period ÷ average value of stock held
Say that last month you used €12,000 of food and your stock was worth about €3,000 on average. Your stock turned four times in the month, roughly once a week. In other words, the average item sat with you for about a week.
These numbers are just an illustration, and the right figure depends on what you cook. Fresh fish should move in days; dry goods can sit longer. What matters is your own trend. If turnover slows month after month, stock is sitting longer and waste usually follows.
How to cut waste in practice
- Buy from your sales history. If you know roughly how many portions of each dish you sell on each weekday, you can order closer to the real need.
- Plan for strong and quiet days. Look at the same weekday over recent weeks, then adjust for holidays, events and weather.
- First in, first out. Label everything with the date it arrived or was prepped, and store new stock behind the old.
- Prep in smaller batches for slower items, topping up during service rather than making a full tray at the start.
- Watch single-use ingredients. An ingredient used by one slow dish is a waste factory. Either find it a second use or reconsider the dish.
- Give surplus a planned outlet. A dish of the day or staff meal can use stock that is still perfectly good, always within your food safety rules.
A worked example
Say you keep a waste log for one week and find most of the value comes from three things: fresh herbs, a speciality cheese used only in one starter, and bread. Herbs get smaller, more frequent orders. The starter moves to a weekend special, so the cheese is only bought for the days it sells. Bread is baked or ordered in two smaller batches. Nothing on the plate gets worse; less goes in the bin.
The missing link: sales data
Every habit above depends on knowing what sells and when. That is why stock and sales belong together: once you know what went out of the kitchen, you know much better what to bring into it.
Where GetFoodies fits
GetFoodies is not a stock management tool. What it gives you is a clear view of the orders on your own channel, which show what sells and when, alongside the sales reports from your POS. And when you have surplus to move, GetChef can suggest a promotion, such as a dish of the day, ready for you to approve and send to your customers. If that helps, you can create your free site.
Start with one week
For seven days, write down what you throw away and roughly what it cost. Most owners are surprised by the total. That number is your motivation, and your baseline for cutting it month after month.
