Who doesn't love pizza? It's cheesy, it's saucy, and you can dress it up with any array of toppings. Because pizza is so well loved, it is the perfect food choice for a large party or gathering. However, ordering pizza for a huge group of 100 or more people does come with its unique challenges. Follow these five tips to ensure it goes off without a hitch.

Call ahead... way ahead.

If you're ordering more than a couple of pizzas, it is nice to give the pizza restaurant more than an hour or two's notice. This way, they don't have to dedicate their entire kitchen to preparing your order and turn away other customers—and you don't have to worry about them running out of ingredients. Call a few days before you need the pizzas so they have time to order extra supplies if needed. Let them know when you want the pizza delivered, and just ask them to call and confirm the order the morning of the event to ensure you don't need to make any last-minute changes.

Have cash on hand for the tip.

When you're ordering a whole stack of pizzas, the restaurant may have to send more than one driver to carry the pizza inside, and the driver will have to work a lot harder than when they only deliver a pizza or two. Since drivers rely on tips, it's nice to give your driver a substantial tip for handling such a large order. Tipping 15% of the order is common convention, though you may want to tip even higher if the weather is bad, the delivery person has to navigate a busy parking lot to reach you, or your event is on the third floor with no elevator access. Ask how much your pizza order will cost when you call to order the pizza so you can take cash out for the tip and have it ready upon delivery.

Take dietary needs into account to some extent.

Surely, you cannot cater to everyone's dietary needs with the pizza order, but you can order a variety of pizzas to hopefully satisfy the most common dietary restrictions in the crowd. For instance, you can order one gluten-free pizza, one vegetarian pizza, and one pizza without cheese. Label these clearly when you put the pizza out for attendees to serve themselves. You may also want to provide some basic sides, like a big bowl of salad or some apples, for attendees who are not comfortable eating the pizza and don't want to appear rude by not eating.

Select toppings wisely.

When feeding such a large crowd, it's usually best to stick to one or two toppings per pizza. This way, you will satisfy the largest number of guests. For example, if you put pineapple, mushrooms, pepperoni, and anchovies on a pizza, then anyone who dislikes any of those ingredients won't want to eat it. If you get separate pizzas with each of those toppings, then there's probably something for everyone. Get a few plain, cheese pizzas to round out the selection and satisfy the pickiest eaters.

Have the pizza cut into smaller slices.

Your pizza will go further if you have it cut into smaller slices. Guests who want to try more than one pizza can do so without indulging in quite so much. People often judge pizza consumption by the number of slices they eat. So for instance, some people may eat three slices whether those slices are four inches wide or 6 inches wide.

With the tips above, you should have an easier time satisfying your guests and ordering pizza for a big event.
