Optimize Your Restaurant Supply Chain Using Square

A restaurant supply chain is every step between your suppliers and the plate: who you buy from, how often, how much, and what happens when something goes wrong. Optimizing it means fewer stockouts, less waste and more predictable costs. Square helps on the demand side, because your sales data shows exactly what you sell and when, and on some plans it also lets you track vendors, purchase orders and stock.

This guide focuses on supplier strategy and purchasing. For counting stock, par levels and day to day inventory, see our guides on managing restaurant inventory and tracking inventory with Square.

Step 1: map your supply chain

Start with a one-page map. For each major category (produce, proteins, dairy, dry goods, beverages, paper and packaging, cleaning supplies) write down:

Your main supplier and a backup supplier
Delivery days, order cutoff times and minimum order
Lead time from order to delivery
Your sales rep's name and phone number
Payment terms

Most restaurants discover at least one category with no backup, or a supplier whose cutoff time does not match when the kitchen actually places orders.

Step 2: choose and manage suppliers deliberately

Broadline distributors versus specialty suppliers

A broadline distributor can cover most of your needs in one delivery, which saves time at the back door. Specialty suppliers (a local bakery, a coffee roaster, a fish purveyor) often bring better quality and a story you can put on the menu. Most independent restaurants use a mix: a broadline distributor for staples and two to four specialty suppliers for signature items.

What to agree with each supplier

How price changes are communicated, and how often prices are updated
Substitution rules: can they swap a brand or size without asking?
Credit process for short, damaged or wrong deliveries
Delivery windows that fit your prep schedule

Put the important terms in writing. For contracts with minimum purchase commitments or exclusivity, it is worth having an attorney review them.

Step 3: forecast orders from Square sales data

Ordering by gut feel leads to the classic cycle of running out on Saturday and throwing food away on Tuesday. Use Square to order from demand instead:

Pull item sales by day of week for the last four to eight weeks from Square Dashboard.
Convert items to ingredients using your recipe cards. If you sell about 120 burgers on a typical Saturday and each uses one 6 oz patty, you need roughly 45 lbs of ground beef for that day.
Adjust for what you know is coming: holidays, local events, weather, a new menu item or a catering order.
Order to cover until the next delivery, plus a small safety buffer for items with long lead times or no backup supplier.

Step 4: use Square to track stock and purchasing

Depending on your plan, Square can do more than report sales:

Stock tracking and low stock alerts. You can track inventory on items and set low stock alerts, and Square can send a daily email listing items that are low or sold out. This works best for items sold as units, like bottled drinks, packaged snacks and retail coffee bags.
Vendors and purchase orders. Square lets you create vendors and purchase orders, then receive deliveries in full or in part and add shipping or other fees, which flow into cost reporting. Square's help center lists purchase orders for Square for Retail Plus and Premium, Square Plus and Premium subscribers with advanced inventory capabilities, and sellers using retail mode. Check whether your plan includes it.
Unit costs. Adding unit costs to items gives you better cost and margin reporting.

If your plan does not include purchase orders, a shared spreadsheet with order guides by supplier works well, as long as everyone uses the same one.

Step 5: tighten receiving

Many supply chain losses happen at the back door. Make receiving a routine:

Check every delivery against the invoice and your order: counts, weights, brands and prices.
Check temperatures on cold and frozen deliveries, following your local health department's guidance.
Note shorts, substitutions and damage on the invoice before the driver leaves, and request credits right away.
Put deliveries away using first in, first out, so older stock is used first.

Step 6: monitor prices and plan for disruptions

Track your top 20 ingredients. Record their price on every invoice. A small increase on a high-volume item matters more than a big increase on a garnish.
Get comparison quotes once or twice a year on your biggest categories.
Plan menu flexibility. Know which dishes can switch to an alternative ingredient if a supplier runs short, and how to mark items as unavailable quickly in Square.
Keep a backup list of local stores or cash and carry options for emergencies.

Common mistakes

Relying on a single supplier for critical items.
Accepting deliveries without checking them.
Ordering the same quantities every week regardless of sales trends.
Never renegotiating with long-time suppliers.

Keep online menus in sync when supply runs short

When an ingredient runs out, your online menu needs to know too. With Orda, your branded app and web ordering pull the menu from Square, and you can hide items or set availability from the Orda dashboard, so customers do not order something the kitchen cannot make. Orders flow straight into Square POS, and more than 10,000 Square businesses have used Orda.
