How do you plan stock for long events?

Long events need thorough stock planning that accounts for duration, guest numbers and the type of catering. Calculate roughly 20 to 30% extra stock as a safety margin, and spread deliveries across the day so everything stays fresh. Good stock planning prevents shortages and spoilage during the event.

How much stock do you actually need for a long event?

For a long event, you calculate your stock based on the number of guests multiplied by the portion size per person, plus a safety margin of 20 to 30%. For an event of 8 hours or longer, plan on 1.5 times the normal amount, because guests consume more over that time.

The basic calculation works like this: number of guests x portion size x event factor x safety margin. For a wedding of 100 people lasting 10 hours, for example, you'd calculate 100 x normal portion x 1.5 x 1.25. That's the basis for your purchasing.

For different types of events, the factors vary. Business events need less stock than parties, because people eat less there. Festivals and outdoor events need more, because of the informal atmosphere and visitors staying longer.

Also take into account the type of catering you're delivering. Buffets need more stock than table service, because guests at a buffet serve themselves more than they actually eat. For walking dinners, plan on roughly 6 to 8 bites per person per hour.

What factors determine your stock needs during long events?

Weather has a big influence on what gets used during long events. In hot weather, guests drink far more and eat lighter, while cold weather increases demand for hot dishes and reduces drinking. Plan your menu and your stock around that.

The time of the event also decides your stock needs. Events that fall during meal times need more food, while events between mealtimes mainly need snacks and drinks. An event that starts at 14:00 and runs to 22:00 overlaps with both lunch and dinner.

Your audience plays an important role. Younger people generally eat and drink more than older people. Business guests are more restrained than party-goers. For family celebrations you need more variety, because you're catering to different age groups.

Alcohol changes your planning too. If drinks are served, people often eat less but stay longer. That calls for more snacks and fewer main courses. At events without alcohol, more soft drinks go through and guests eat more heartily.

Season matters too. In winter, people want hearty, warm dishes. Summer events call for lighter food, more salads and cold drinks. Adjust your stock planning accordingly, and less ends up in the bin.

How do you stop your stock spoiling during long events?

Spread your deliveries across the day, and have perishable products delivered only shortly before use. Cold products like meat, fish and dairy can be out of the fridge for a maximum of 4 hours, so time your deliveries and preparation around that. Keep hot dishes at a minimum of 65 degrees.

Make sure you have enough cooling capacity for long events. A refrigerated van is essential if the venue has little cold storage. Keep product groups in separate cooling, to prevent cross-contamination and keep each group at the right temperature.

Rotation matters at long events. Use the FIFO principle: First In, First Out. Use the products that were delivered first, first. Label everything with times, so your team knows what goes first.

Plan your prep windows smartly. Cook in small batches that you serve within 2 hours. That way nothing sits waiting too long, and quality stays up. For events longer than 6 hours, plan several prep windows.

Also watch storage during the event itself. Use hot-holding equipment for hot dishes and cooling elements for cold products. Cover everything, check temperatures regularly and write them down.

What do you do if your stock unexpectedly runs out during an event?

Always have a backup plan ready with the numbers of suppliers who can deliver on short notice too. Make arrangements for rush deliveries in advance, and keep a list of nearby supermarkets or wholesalers. If you run into trouble, you can also contact us.

Have alternative menu options ready that you can make fast with basic ingredients you always have in stock. Think pasta, soups or simple salads that you can stretch with whatever's left. Train your team in those few backup dishes.

Build a relationship with other caterers in your area. In emergencies you help each other out with stock or staff. A number like that in your phone is worth more on a Saturday night than any list.

Prevention still beats fixing things afterwards. Count your stock every hour during long events, and reorder as soon as you see something running out faster than expected. Reordering too early costs you a few tenners, too late costs you the evening.

Call your client as soon as something goes wrong. Explain what's happening and what solution you're offering. Most clients value honesty more than perfection. Offer something to make up for it where you can.

Which software helps you track stock during events?

With a stock system on your phone or tablet, you see straight away how much you've got left during the event. You can update the count anywhere, including from the venue. Link ingredients to dishes, and you see immediately how many portions you can still make.

Spreadsheets remain popular because they're flexible and accessible. Make templates for different types of events and share them with your team through the cloud. That way everyone updates the stock and everyone sees the same count.

Paper inventory lists are useful as a backup and for team members who'd rather not work with an app. Make clear lists per product group and put one person in charge of keeping them. Transfer them into your records after the event.

Catering software ties your stock to your quotes and your plan. You see per dish how many ingredients you need, and tick off during the event what's being used. Afterwards you know exactly what you actually used.

For large events, a system that alerts you the moment a product is nearly out helps a lot. Some systems even pass that order straight on to your regular supplier. If you run large events often, that pays for itself quickly.

A long event lives or dies by your stock planning. Calculate sharply, stay flexible and track what's being used during the day, so you don't have to improvise in the evening. Catermonkey works out your purchasing list from your recipes and the number of guests, so you can see what you need and what it costs before the event even starts.

Frequently asked questions

How do I calculate exactly how much extra staff I need to track stock during long events?

Plan on one extra person per 50 to 75 guests to track stock at events longer than 6 hours. That person counts stock, arranges deliveries and keeps in touch with your suppliers. For more than 200 guests, put someone on it who does nothing else.

What are the biggest mistakes caterers make with stock planning for long events?

The three biggest mistakes are: underestimating consumption in the final hours (people eat more once they're drinking), not accounting for weather changes during outdoor events, and leaving it too late to discuss possible reorders with your suppliers. Always plan 15% extra for the final 3 hours of the event.

How do I handle different dietary needs with large stock orders for long events?

Ask for specific dietary needs at least 2 weeks in advance, and plan on 10 to 15% vegetarians, 5% vegans and 8% gluten-free if you don't have exact numbers. Order separate ingredients for these groups and keep them clearly separated during preparation, to prevent cross-contamination.

What legal aspects do I need to watch for food safety during long events?

Keep temperature logs for your cold and hot products (hold hot food at a minimum of 65°C), note delivery times and work to HACCP principles. For events longer than 8 hours, you're required to measure and record temperatures every 2 hours. Keep those records for at least 2 years as evidence.

What's the best way to prepare my suppliers for possible rush orders during the event?

Let your suppliers know a week in advance that the event is coming up, and ask if they can stand by during those hours. Make concrete agreements on delivery times (usually within 2 to 3 hours) and agree a maximum amount for rush deliveries. Give them your running order, so they know when the peak falls.

What should I do with leftover stock after a long event?

Check the shelf life and food safety of all products first. Unused, properly chilled ingredients can be used for another event within 24 hours. Throw away prepared food that's been out of the fridge for more than 4 hours. Whatever's still good, you can donate to a food bank.

How do I make sure my team is well trained in monitoring stock during stressful moments?

Practise monthly with situations that really happen, like cooling failing or a delivery not showing up. Make short checklists your team knows by heart. For every event, assign one person as the main point of responsibility for stock, and make sure at least 2 team members can take over completely.
