Inventory Aging Visibility: Preventing Dead Stock, Surprises, and Cash Getting Stuck on Shelves

Aging inventory is not just a warehouse issue, it is a cash issue

Inventory aging visibility matters because inventory that sits too long quietly taxes your business. Research shows that dead stock ties up cash, increases storage costs, and raises the odds of damage, obsolescence, and write-offs. When you cannot see what is aging, you cannot act early. You end up discounting in a panic, donating in a rush, or writing off inventory that could have been sold with better planning.

Many brands come to G10 after realizing their inventory visibility stops at total counts. They know how many units they have, but not how long those units have been sitting, where the oldest units are located, and whether the warehouse is following first-in, first-out behavior when it matters. Inventory aging visibility is how you stop discovering dead stock the hard way.

As Maureen Milligan said, "Most of the customers who come to us from another 3PL, their challenges have always been access to their data, order accuracy and efficiency, and basically just meeting the committed requirements. So we've seen a lot of people come disillusioned by their last 3PL, where their orders weren't getting fulfilled in time, their inventory accuracy was not there, and they were not able to satisfy customer orders." Aging visibility helps solve the access-to-data problem because it adds a time layer to inventory truth.

Aging visibility depends on real time receiving and movement history

You cannot see inventory age if you cannot trust the timestamps behind it. Inventory aging visibility starts with accurate receiving timestamps and continues with accurate movement history. Research shows that when receiving is delayed or recorded inconsistently, age reporting becomes unreliable, and teams end up making the wrong decisions about what to sell first.

Bryan Wright described the kind of timestamped tracking history that supports real time visibility when he said, "Absolutely. We have portals that show you the data. We have history that shows you all of that tracking. It shows the product landed on the dock at 8 o'clock. At 8:10, John picked it up and took it to location XYZ, and at 10 o'clock, we picked two items off of that pellet in the location 1, 2, 3, 4, order, you know, ABC, and at 11 o'clock, we packed it, we put it in this box and put this label number on it, and all the way through the process onto the truck and to the customer." Inventory aging visibility relies on the same idea: a clear timeline of when inventory arrived, where it went, and how it moved.

Scan-based execution keeps aging data believable

Aging visibility falls apart when inventory can move without being recorded. If a pallet relocates without scans, the system can no longer connect age to location and status. Scan-based execution is what keeps aging data aligned with reality.

As Connor Perkins said, "You want everything to be scanned in the warehouse, nothing done on paper. You can lose a lot of money in this industry by you know having people ship stuff wrong, or store it wrong, and now it's lost somewhere. So having a 3PL and WMS that is 100% scan-based is crucial." Aging visibility depends on this because scans preserve the record that links inventory to timestamps.

Connor also said, "One of the pain points our clients have experienced with previous 3PLSs is inventory accuracy; maybe their previous 3PL wasn't great at picking the orders accurately. So they were losing money by shipping wrong items or wrong quantities of items." When accuracy breaks, aging visibility breaks too, because the system cannot reliably tell which units are actually present and which units are old.

Aging visibility should support FIFO and lot discipline when it matters

Not every product requires strict FIFO, but many do. Research shows that items with shelf life, packaging changes, seasonal relevance, or regulatory constraints require tighter control over what ships first. Inventory aging visibility supports this by showing which units are oldest and where they sit.

Aging visibility should make it easy to identify aged inventory by SKU, by location, and by status. If aged inventory is stuck in bulk while newer inventory is being picked first, the system should surface that pattern because it signals a process problem.

Aging visibility should separate sellable age from non-sellable age

Aged inventory is not always available inventory. Some aged inventory is quarantined, damaged, or reserved. Inventory aging visibility should show age by inventory state so teams do not make decisions based on the wrong pool. Research shows that state confusion is a common driver of bad planning decisions because teams assume inventory is available when it is not.

When age is visible by state, brands can decide whether to rework damaged inventory, liquidate aged inventory, or reallocate inventory across channels.

Portals make aging visibility usable for planners and operators

Inventory aging visibility is most useful when brands can access it directly. A portal that surfaces inventory levels and related metrics makes age-based decisions practical instead of theoretical.

As Maureen said, "We're in the last stages of developing a new portal that will give customers real-time visibility to their on-time order fulfillment, inventory accuracy, and even inventory levels so that they can monitor those things directly in our systems." Aging visibility becomes more valuable when brands can monitor inventory levels directly, because age reporting depends on accurate inventory levels.

She added, "A lot of the 3PL customer expectations are that order fulfillment is happening extremely timely, that our inventory is accurate, that we're able to execute on their orders very quickly, and get them shipped the same day. So what these real-time portals provide our customers is 100% visibility." Aging is part of that visibility because it adds a time dimension to the inventory story.

Transaction history explains why inventory got old

Seeing that inventory is old is helpful. Understanding why it got old is more helpful. Transaction history helps explain how inventory became aged: slow sales, poor replenishment planning, mis-slotting, returns inflating counts, or channel changes that reduced demand. Research shows that root-cause analysis reduces repeat dead stock because teams can fix the planning and merchandising decisions that created the aging.

As Connor said, "Our clients get best-in-class visibility and transparency. They can see their daily orders, they can see KPIs, and they can see historical transactions. They can look at a daily level or go into the more granular version where they're looking at transactional history on an item." That transaction history supports aging investigations because it shows how inventory moved and why it did not move.

He also said, "You have easy access to reporting and you can export to Excel, or really any format that you like you know directly from our WMS portal." Exportable reporting helps brands analyze aging patterns and align decisions across teams.

Aging visibility reduces dead stock and prevents last-minute discounting

When you can see aging early, you can act early. You can run promotions while inventory still has value. You can shift channel strategy before a season ends. You can adjust replenishment before cash gets stuck. Research shows that proactive aging management reduces write-offs because it prevents inventory from crossing the point where it becomes unsellable.

As Maureen said, "We will take in your inbounds, we will get them received and reported back to you within our SLAs, and oftentimes more quickly than what we contracted for. We will ship your orders out the day they're required. And our inventory accuracy is generally right there at that 99.7% that we agreed. So that's one of the areas where we really do excel, and where we've been able to win business." Aging visibility supports better decisions on top of accurate inventory because it helps brands act before inventory becomes a write-off.

Aging visibility rebuilds confidence after bad inventory data

Brands often switch 3PLs because they lost confidence in inventory. Aging inventory can be a surprise when data is unclear, and surprises are expensive. Inventory aging visibility rebuilds confidence by making the age profile visible and explainable.

As Maureen said, "For customers who have come to us from a bad 3PL relationship, they experience relief. They're suddenly seeing their business scaling, that the data supports what we agreed to, and then the trust begins to build." Aging visibility contributes to that relief because inventory truth becomes actionable instead of mysterious.

Inventory aging visibility is now essential

As catalogs grow and demand patterns shift faster, dead stock risk rises. Inventory aging visibility requires accurate receiving timestamps, scan-based execution, portals that expose inventory levels, and reporting that links age to transaction history.

As Connor said, "This is one of our strengths. G10 is on the cutting edge for this kind of transparency and feedback for clients." If your brand wants less cash trapped in dead stock and fewer unpleasant surprises, inventory aging visibility is a practical place to focus.
