For a fast-food chain , the challenge isn’t finding cheap products, but ensuring that the same product is available in exactly the same way at every location. A customer expects the same burger they ate at the Kadıköy location to be available at the Başakşehir location as well; it is not the menu but the repeatability of the supply chain that meets that expectation. Since 1995, Santral Gıda has ensured this consistency for chain restaurants by making deliveries six days a week to all 39 districts of Istanbul using its own vehicles.

How does wholesale food supply for a fast-food chain work?

The supply chain differs from a single-store supply chain in three ways: product specifications are standardized, the delivery schedule is planned on a store-by-store basis, and pricing is determined based on total volume. Even if stores place orders separately, pricing and the product list are defined centrally.

In practice, it works like this: the brand, weight, and case configuration are specified in writing for each item on the menu. If a product cannot be supplied, a random substitute is not sent—the customer is notified in advance, and an approved alternative is used. The most costly mistake in the chain is when a branch uses a different product.

The real issue with the supply chain isn’t price—it’s standards

The difference between two different brands of the same product is reflected in the cooking time, serving weight, and flavor profile. If the cut size of the potatoes changes, the frying time changes; if the fat content of the cheese changes, its melting behavior changes; if the consistency of the sauce changes, the amount used per serving changes. All three directly affect the unit cost.

That’s why, in chain restaurants, the right question isn’t “How much does this item cost?” but rather “What will my cost per serving be for this item, and will that figure remain constant for six months?”

Frozen potatoes: The cut determines the menu

The best-selling item on a fast-food menu is usually french fries, and the thickness of the cuts is no accident. As the cuts get thicker, the surface-to-volume ratio decreases and oil absorption decreases, but cooking time increases and the crispiness is lost more quickly.

For the full product line, as well as information on fryer temperature, oil management, and portion sizing, please refer to our guide for frozen potatoes. Products: Bonfrit 7×7, Bonfrit 9×9, Bonfrit 9×18. The entire product line is available in the Frozen Foods category.

What kind of cheese is used in a burger?

What makes a burger great isn’t the name of the cheese, but how it melts. Sliced cheddar and sliced sandwich cheese melt quickly and spread evenly over the patty; when block cheese is cut to size, the thickness of the slices cannot be standardized, and each burger turns out differently. In a chain restaurant, sliced cheese is practically a must for consistent portion sizes.

With pizza and open-faced toast, however, the problem is the opposite: the cheese releases oil or turns brown. We’ve explained in detail how this relates to temperature and cheese composition in our pizza cheese guide. For product options, check out the “Cheeses” category: sliced cheddar, sliced toast cheese, block cheddar.

Why are sauce and base supplies managed separately?

The sauce is the only item on the fast-food menu that embodies the brand identity. Potatoes are similar everywhere; it’s the sauce that sets them apart. That’s why switching sauce suppliers should be the last cost-saving measure to consider.

From an operational standpoint, the choice of packaging is important: tubs and jugs lower the unit cost but shorten the shelf life once opened. For sauces with low daily consumption, small packages are the right choice, while large packages are best for those with high consumption. The “Sauces & Bases” category offers both branded and generic options; for chains serving Asian menus, our Asian sauces guide explains which sauce is used where.

Branch-based delivery or bulk shipment to a single location?

Both options are possible, and the decision depends on the branches’ warehouse space. Bulk shipments to a central warehouse reduce the number of deliveries and generally offer better prices; however, this requires the chain to have established its own internal distribution system. Branch-based delivery, on the other hand, allows each branch to maintain its own inventory and is better suited for branches with limited warehouse space, where goods are delivered more frequently in smaller batches.

Since we make deliveries 6 days a week within Istanbul, it is possible to reduce the inventory holding period to 1–2 days even under a branch-based model. For frozen products, this directly translates to savings in freezer space.

Packaging decision: box or pallet?

A simple rule: if you can’t finish a package within its shelf life after opening it, the package is too big for you. Any savings on the unit price are easily wiped out by waste. With frozen products, frequently opening the freezer door after a package has been opened also reduces the product’s quality.

When it comes to supplies and cleaning, the situation is the opposite: since cleaning supplies and other consumables don’t spoil, bulk packaging is almost always the right choice. In a fast-food restaurant, napkins, wrapping paper, gloves, and dishwashing detergent are used just as regularly as the menu items, but they’re often left at the bottom of the order list.

Supply preparations when opening a new branch

The most common mistake made when opening a new branch is placing the first order on opening day. The correct sequence: menu items and portion sizes are finalized, the product list and prices are set, a test order arrives at least one week before the opening, and staff work with those products to establish consistent portion sizes. You don’t want any surprises on opening day.

How do orders and deliveries work?

You place your order by phone, WhatsApp, or email; we prepare a quote based on the product list and quantities. Once you approve it, the order is added to the next day’s delivery route. We deliver to all 39 districts of Istanbul 6 days a week using our own vehicles; products requiring a cold chain are transported in refrigerated vehicles.

Since 1995, we have been exclusively serving corporate clients—we do not offer retail sales or online payments. Prices are determined on a quote basis, and special volume-based pricing is available for regular purchases. You can view our entire product lineup in our catalog and contact us for a quote.
