Restaurant FIFO: How to Implement First In, First Out

What Is FIFO and Why Does It Matter?

First In, First Out (FIFO) is the inventory management principle that ensures older stock is used before newer stock. When a delivery arrives, new product goes behind existing product. When cooks pull ingredients, they take from the front — the oldest items first.

Without FIFO, the opposite happens naturally: cooks grab the most accessible product, which is often the newest. Older stock sits at the back and expires. Avocados, dairy, proteins, and prepared items all have limited shelf life — FIFO is the system that ensures they get used before they spoil.

Where FIFO Applies in a Restaurant Kitchen

FIFO applies to every storage area:

• Walk-in refrigerator: proteins, dairy, produce, sauces, prepared items
• Dry storage: canned goods, grains, pasta, oils, condiments
• Freezer: proteins, dough, pre-portioned items, ice cream
• Bar stock: spirits, mixers, garnishes, ice
• Prep containers: stocks, sauces, dressings, and mise en place

The Practical Implementation: Step by Step

Step 1: Date Label Everything

Every item that enters your kitchen must be date-labeled with the received date. This is non-negotiable. Without labels, FIFO is impossible — no one can tell which case of chicken arrived first.

Use blue painter's tape and permanent marker (cheap and effective) or purpose-made dissolvable date labels (cleaner and food-safe). The label must show: item name, received date, and use-by date.

Step 2: Designate a Receiving Protocol

When deliveries arrive, the receiving process determines whether FIFO is possible. The receiving team must: check delivery quantities and condition, label everything immediately upon receiving, and place new stock behind existing stock in every storage area.

If new stock gets stacked on top of old stock (the path of least resistance), FIFO is broken before it starts.

Step 3: Organize Storage by Use-By Date

In the walk-in, organize shelves so the oldest items are at the front and at eye level. New deliveries go to the back or bottom. For prep containers, put the newest container at the back; cooks always reach for the front.

Step 4: Train the Entire Team

FIFO is only as strong as the newest cook's compliance. Train every team member on the system during onboarding. Make it a line walk standard — the opening sous chef checks storage areas to verify rotation during their morning inspection.

Step 5: Build It Into the Prep Process

Incorporate FIFO checks into prep routines. Before starting any prep, cooks should check what is already made and use the oldest portion first. Before morning prep begins, a quick walk-in review identifies items approaching their use-by date that should be prioritized or incorporated into staff meals.

FIFO and Inventory Counts

FIFO makes inventory counts more accurate because it enforces order. Items are consistently located in logical positions (oldest front, newest back), making counts faster and more reliable.

When running inventory in Karu, storage areas are organized by location — the same layout as your physical walk-in. This connection between how you store and how you count eliminates the confusion of random product placement.

Common FIFO Failures and How to Fix Them

• Deliveries not labeled: Make labeling mandatory before any product enters storage. Hold receiving staff accountable.
• New product placed in front: Walk-in shelves should physically require placing new stock behind old (use depth guides or shelf dividers)
• Prep containers stacked randomly: Date-label every prep container and organize chronologically
• Staff ignoring the system: Post signage, include FIFO in shift briefings, and make it part of line checks
