No one wants to open a box of spoiled snacks, expired meds, or out-of-season products.
And yet, that’s exactly what happens when warehouses lose track of what came in when, or when teams are too busy doing other things rather than picking stock in the right order.
If you’ve ever dealt with a pile-up of dead stock or had to write off products that never made it to the shelf, you know how quickly things can spiral. Good inventory flow isn’t just about saving money; it’s also about optimizing warehouse efficiency. It’s about staying ahead of problems before they cost you customers.
FIFO (or First In, First Out) is one of the simplest ways to stay in control. It’s a method that helps you move older inventory first, so nothing sits too long or gets forgotten at the back of a rack.
In this guide, we’ll explain how FIFO works in a warehouse, when to use it, and how smart tools like Da Vinci WMS help teams apply it at scale without the guesswork.
What Is FIFO in Warehousing?
FIFO stands for First In, First Out—a simple but powerful method used to manage inventory movement inside a warehouse. It means that the items received first are also the ones picked, packed, or shipped first.
In warehousing, this approach ensures that products don’t sit too long on shelves, collect dust, or worse, expire before they’re ever used. It’s a strategy designed to keep inventory flowing in a logical, time-based sequence.
Let’s say a food distributor receives two pallets of canned soup; one on July 2nd and another on July 10th.
With FIFO in place, the system (or warehouse worker) ensures the July 2nd stock gets picked before touching the newer pallet. That way, nothing reaches its expiration date before it’s sold or consumed.
It’s worth noting that FIFO in warehousing is not the same as FIFO in accounting. While both follow the same “first in, first out” logic, accounting FIFO deals with cost valuation, whereas warehousing FIFO deals with physical stock movement and operational control.
Most warehouses use FIFO either by design or necessity, especially in industries where shelf life, freshness, or regulatory compliance plays a key role. But even in less time-sensitive environments, FIFO can help reduce overstock, improve space usage, and create more predictable inventory turnover.
How FIFO Works in a Warehouse (Step-by-Step)
At a high level, FIFO is about moving the oldest stock first. But making that happen consistently requires more than just good intentions. It needs structure, visibility, and coordination across receiving, storage, and picking.
Here’s how FIFO typically works inside a warehouse:
Step #1: Inventory is received and dated
Every item that enters the warehouse is logged with a receive date, or, in some cases, an expiration or production date. This timestamp is critical for FIFO to work. Whether done manually or automatically via barcode scanning, the system needs to know when each unit arrived.
Step #2: Stock is stored in FIFO-friendly locations
To make FIFO possible, warehouses often use specific storage layouts that support forward product flow. Think pallet flow racks, drive-through racking, or floor staging that allows new stock to load from one side and old stock to leave from the other.
Even with standard shelving, teams can apply FIFO logic by placing newer inventory behind older inventory or by slotting items in separate zones by receive date.
Step #3: The system identifies the oldest available stock
When an order comes in, the WMS checks available inventory and flags the items with the earliest receive date. The best WMSs (like Da Vinci WMS) allow you to configure FIFO rules based on the receive date, lot number, batch code, or expiration date, depending on your product type.
Step #4: Pickers are guided to the correct inventory
With FIFO enabled, pickers receive instructions that guide them to the oldest qualifying item first. This reduces the chance of human error and helps maintain product freshness without relying on memory or guesswork.
Step #5: Inventory levels are updated in real time
Once the item is picked, the system updates inventory counts and records the movement. This closes the loop and ensures that the next pick reflects the updated FIFO priority.
In a smaller warehouse, FIFO can be managed manually, but as volume increases, it quickly becomes difficult to track without system support. A cloud-based WMS, such as Da Vinci, facilitates the setup, automation, and scaling of FIFO workflows with precision.
Benefits of Using FIFO in Warehousing
FIFO isn’t just a best practice for food and pharma brands. When done correctly, it enhances operational efficiency across the board, from inventory rotation to order fulfillment accuracy.
Here are some of the biggest advantages of using FIFO in your warehouse:
1. Reduces spoilage and waste
Products don’t get left behind or forgotten at the back of a shelf. By ensuring older items are used or shipped first, FIFO helps teams avoid costly write-offs and product recalls. This is especially critical for perishables, chemicals, and anything with a strict shelf life.
2. Improves inventory turnover
FIFO helps maintain a steady flow of stock, ensuring that nothing sits idle for too long. This not only frees up space but also reduces the risk of holding onto outdated or obsolete inventory—two common problems in poor inventory management workflows.
The result? Faster inventory cycles and more predictable replenishment.
3. Supports regulatory compliance
In highly regulated industries like healthcare, cosmetics, and food and beverage, FIFO supports traceability and product safety. If there’s ever a recall, you’ll have a clear audit trail of what was picked, when, and where it went.
4. Boosts customer satisfaction
Customers expect quality, consistency, and fresh stock, especially when ordering consumables. FIFO helps make sure that what arrives at the customer’s door is exactly what they paid for, within the expected shelf life, and in good condition.
5. Streamlines stock audits and forecasting
When you know that older stock is moving first, it’s easier to forecast demand, plan purchasing, and spot anomalies in your stock flow. It gives warehouse managers more confidence in their numbers and reduces last-minute surprises.
All these benefits are true and tested, but when FIFO is supported by a smart WMS like Da Vinci, these benefits compound. Da Vinci WMS eliminates the guesswork of picking, ensures FIFO rules are applied consistently, and provides teams with the visibility they need to move quickly and stay in control.
When Should You Use FIFO?
FIFO is a reliable go-to for many warehouse environments, but it shines brightest in industries where shelf life, freshness, or product integrity are non-negotiable.
Here’s when FIFO makes the most sense:
1. When you’re storing perishable or time-sensitive goods
If you’re handling products that can spoil, expire, or degrade over time, FIFO is essential. That includes food and beverages, pharmaceuticals, cosmetics, supplements, and even certain chemicals. Moving older stock first helps reduce waste and avoid compliance issues.
2. When your products have batch or lot tracking requirements
Many businesses that deal with serialized or lot-controlled items use FIFO to ensure traceability and meet quality control standards. It makes recalls and audits smoother and reduces the risk of expired goods reaching customers.
3. When you want a predictable inventory flow
Even if your products don’t expire, FIFO helps create more consistent movement across SKUs. This makes forecasting, warehouse replenishment, and storage planning more accurate and efficient, especially in high-volume operations.
4. When customer satisfaction depends on freshness
Customers expect what they order to be in top condition. Whether it’s packaged snacks, over-the-counter vitamins, or seasonal products, FIFO helps make sure that the inventory you ship is timely, clean, and exactly what they’re expecting.
When FIFO might not be ideal
There are a few cases where FIFO isn’t the best fit. For example, warehouses that manage high-value goods with volatile prices, such as electronics or commodities, may use LIFO for cost control. And in some fast-moving environments, FEFO (First Expired, First Out) may be more suitable if expiry dates are more important than receipt dates.
However, for most use cases, especially where freshness is a priority, FIFO is a proven strategy that’s easy to implement and scale.
FIFO vs. LIFO vs. FEFO
There’s more than one way to move inventory through a warehouse. FIFO is often the go-to, but depending on your product type and operational goals, you might use other inventory management strategies like LIFO or FEFO.
Here’s the difference between these three at a glance:
Comparison Table: FIFO vs. LIFO vs. FEFO
| Method | What It Prioritizes | Best For | Common Industries |
| FIFO (First In, First Out) | Oldest received items | Reducing spoilage, rotating inventory | Food, pharma, cosmetics |
| LIFO (Last In, First Out) | Most recently received | Stable-cost items, financial reporting | Manufacturing, accounting |
| FEFO (First Expired, First Out) | Closest expiry dates | Regulatory compliance, product safety | Pharma, grocery, healthcare |
Now, let’s break each one down with examples to show how they work in practice:
What Is FIFO?
First In, First Out means the oldest inventory gets picked, packed, or shipped first.
This method is commonly used for products with a limited shelf life, such as dairy, cosmetics, or over-the-counter medications. For example, if a grocery warehouse receives a pallet of yogurt on June 1st and another on June 8th, the FIFO (First-In, First-Out) method ensures that the June 1st batch is picked and shipped first. That way, nothing expires while sitting in storage.
It’s also widely used in general retail and e-commerce to rotate stock and reduce aging inventory.
What Is LIFO?
Last In, First Out is the reverse. The newest inventory is used or shipped first, and the older stock stays in storage.
LIFO is rarely applied in physical warehouse operations because it’s difficult to set up storage systems that support it. But it’s often used in accounting to calculate the cost of goods sold during periods of inflation.
For instance, a metal parts supplier might purchase copper inventory in January at $ 3 per pound and again in March at $ 4 per pound. Under LIFO, they account for the $4/lb inventory first when calculating profit margins, even though older inventory still exists in storage. Operationally, the stock may still be processed in FIFO order, but LIFO is applied behind the scenes for cost tracking purposes.
What Is FEFO?
First Expired, First Out focuses on expiry dates rather than the date the stock was received.
This is especially useful when products with the same SKU arrive at different times with different expiration dates.
A pharmaceutical warehouse, for example, might receive two lots of allergy medication. One batch expires in 6 months, the other in 12 months. Even if the 6-month batch was received later, FEFO ensures it’s picked and shipped first because what matters is how soon it expires, not when it was received.
FEFO is highly precise, but it requires a WMS that can track expiry data at the lot or batch level. Systems like Da Vinci support this level of detail with configurable picking rules and real-time alerts.
Common FIFO Challenges in Warehouses
FIFO might seem easy on paper, but making it work on the warehouse floor is a different story. Especially when you’re dealing with thousands of SKUs, shifting demand, or a team that’s juggling multiple priorities at once.
Here’s a closer look at the operational roadblocks that often get in the way of effective FIFO execution:
1. Manual processes leave too much to chance
In warehouses without a WMS, FIFO often relies on memory, labels, or handwritten notes. A worker might guess which pallet came in first or go for the one closest to the aisle. These shortcuts are understandable when you’re under pressure to make quick decisions, but they lead to missed stock, expired items, and frustrated customers.
One mislabeled box can sit untouched for months, while newer stock continues to be pulled. And by the time someone realizes, it’s often too late to salvage the product.
2. Warehouse layouts that fight the process
FIFO-friendly movement requires an intentional setup, such as flow-through racking or staging areas that allow teams to access older stock first. However, many warehouses evolve reactively, rather than strategically. If space is tight or racking systems aren’t optimized, newer items get stacked in front of older ones. That makes proper rotation difficult, especially for bulky or slow-moving goods.
Even well-trained teams can’t pick FIFO if the layout doesn’t support it.
3. Incomplete or inaccurate data at receiving
FIFO lives and dies on accurate intake data. If your team misses a receive date, fails to log a batch number, or doesn’t scan an expiration date correctly, the system can’t enforce FIFO. And in manual setups, it’s easy for those details to get skipped, especially during peak receiving hours.
Once the data is wrong, every pick after that is a gamble.
4. Too many SKUs, not enough visibility
Managing FIFO for a handful of products is doable. But when you’re tracking hundreds or thousands of SKUs with varying shelf lives and turn rates, it’s nearly impossible to keep up manually. Small mistakes compound fast. You might move through some SKUs correctly, but others sit idle and get overlooked.
Without system-generated FIFO prompts or inventory aging reports, it’s hard to know what’s falling behind until it becomes unsellable.
5. Inconsistent execution across shifts or teams
Warehouse turnover can be high. Add in seasonal workers, different shift leads, or unclear SOPs, and you get wildly inconsistent execution. One picker might follow FIFO by the book. Another might skip steps to hit speed targets. And unless someone’s monitoring every pick in real time, these inconsistencies quietly erode FIFO compliance.
These are precisely the kinds of problems Da Vinci WMS is designed to solve.
It takes the pressure off your team by automating FIFO logic from receiving through to picking. The system tracks expiration dates, enforces date-based rules, and directs workers precisely where to go, eliminating second-guessing and risky shortcuts. You achieve better compliance, faster pick times, and significantly fewer write-offs.
How a WMS Helps You Apply FIFO (And Why Da Vinci Makes It Easier)
Applying FIFO consistently across every SKU, every shift, and every picking zone requires more than a warehouse policy. It requires a system that thinks ahead, sees everything, and guides your team with precision. Warehouse management systems (WMSs) are specifically designed for this purpose.
Here’s how a WMS like Da Vinci helps put FIFO into action:
1. Automates FIFO logic at every stage
With a WMS, FIFO isn’t something your team has to remember; it’s built into the workflow. From the moment inventory is received, the system logs receive dates, batch numbers, or expiration data. When it’s time to pick, Da Vinci applies FIFO rules automatically, ensuring the oldest stock is selected first.
Whether you’re using the receipt date or expiry date as the primary rule, the logic is enforced without room for error.
2. Guides pickers to the right product
Da Vinci generates optimized pick paths that take FIFO into account, directing pickers to the exact location of the oldest inventory. There’s no need to guess or search; just follow the instructions. This enables teams to move efficiently while adhering to inventory rotation rules.
For high-volume operations, that means less training, fewer mistakes, and faster fulfillment.
3. Tracks inventory by lot, batch, or expiration
For industries that require tighter traceability, Da Vinci allows you to configure FIFO based on lot numbers or expiration dates, in addition to the receive date. This is especially useful for pharmaceuticals, cosmetics, or food products, where shelf life matters more than when the product arrived.
If one lot expires earlier than another, the system flags it for priority picking, ensuring compliance and reducing waste.
4. Reduces aging inventory and dead stock
Da Vinci gives warehouse managers real-time visibility into inventory age across all locations. You can generate reports that show which stock is approaching expiration, how long items have been in stock, and whether FIFO rules are being followed.
That makes it easier to act before a product becomes unsellable and keep inventory flowing across the board.
5. Adapts to your warehouse layout
Whether you’re using standard pallet racking, flow-through shelves, or custom zones, Da Vinci adjusts to your physical layout. It supports location-based picking strategies and smart slotting, so FIFO can be applied even in complex or space-constrained environments.
A WMS like Da Vinci doesn’t just make FIFO possible; it makes it scalable, reliable, and fast. Instead of asking your team to remember every rule, the system applies them for you in real-time, with total visibility from dock to delivery.
FIFO in Warehousing FAQs
What does FIFO mean in a warehouse?
FIFO stands for First In, First Out. It’s an inventory method where the oldest stock is picked or shipped first. This helps prevent spoilage, reduce waste, and improve inventory turnover.
Is FIFO the same as FEFO?
No. While FIFO prioritizes the oldest received inventory, FEFO (First Expired, First Out) focuses on expiration dates. FEFO is used when expiry matters more than the receive date, such as in pharmaceuticals or food production.
Why is FIFO important in warehousing?
FIFO ensures that stock doesn’t sit too long or expire before it’s used. It helps maintain product quality, reduce dead stock, and meet compliance standards in regulated industries.
Can FIFO be applied manually?
It can, but scaling it without a system in place is difficult. Manual FIFO tracking often leads to errors, missed dates, and inconsistent picking. Most high-volume operations utilize a WMS, such as Da Vinci, to automate FIFO workflows.
What happens if FIFO isn’t followed correctly?
You risk product spoilage, customer complaints, write-offs, and compliance issues. Over time, poor FIFO execution can lead to shrinking margins and damaged brand trust.
Is FIFO required by law?
Not always, but in regulated industries like food, healthcare, and cosmetics, following FIFO or FEFO is often expected to meet safety and quality standards. Even when not legally required, it’s widely considered best practice.
FIFO Is Simple, But Only When Your System Supports It
The idea behind FIFO is straightforward: move older inventory first, minimize waste, and maintain a steady stock flow. However, in the real world, where teams are racing to meet deadlines and SKUs are spread across multiple zones, FIFO becomes increasingly difficult to enforce without the right tools.
Manual tracking leads to mistakes. Poor layouts create bottlenecks. And without real-time data, teams are left guessing what should go out next.
That’s where a warehouse management system like Da Vinci WMS makes all the difference.
With Da Vinci, FIFO becomes an integral part of your process, not something your team has to think about separately. From intake to picking, the system automatically applies FIFO rules, guides workers to the correct products, and provides managers with full visibility into inventory age and movement. It’s fast, reliable, and built for scale.
If you’re serious about reducing waste, improving turnover, and keeping customers happy, it starts with better inventory flow.
