Your inventory is just cash you’ve already spent

The end of the year is approaching, which means it’s time to roll out the Q4 reorder spreadsheet. If you’ve heard all the “top” inventory management tips and tricks a hundred times before, and still don’t know how much stock to send in this time around, you’re not alone.

Tell me if this scenario sounds familiar: Last Q4 looked great on paper. “Brand X” pulled off the year's largest restock with record sales. When it was time to fund the next round of production, Andy, Brand X’s founder, realized he couldn’t afford the runway. What happened?

Here’s the part nobody talks about: Andy wired $40,000 to his manufacturer back in July. Poof. That money was gone, and it didn’t magically reappear when the units sold in November. It came back in pieces, two weeks at a time, minus fees and returns. And 20% of his units didn’t even move. By year-end, Brand X's working capital was slim to none.

Personally, I have watched this play out many times.

What if I told you there’s an easier way to figure out this year’s restock and find out where your money is getting stuck along the way? The truth is, you can streamline this process, and it all starts with a simple reframe: Inventory is a cash decision.

Why an inventory decision is really a cash decision

Inventory is a cash decision because it depends on working capital at every stage of its life. First, you need cash to buy the stock. While you wait for units to sell, you need cash to keep your business running. After inventory sells, you need that new cash influx to repeat the cycle. Cash is king, especially when you’re running a business through Amazon.

When deciding how much to purchase for Q4, ask yourself these questions first:

• How much capital can I afford to have parked and illiquid this quarter?

• What happens to my business if some of that cash sits unmoving longer than I planned?

• Where does my cash (inventory) most often get stuck in Amazon’s system?

When I work with Evolved Commerce clients, most brand owners can answer the first two questions pretty easily, but often overlook the third. Where is my money getting stuck? And what can I do to mitigate potential losses?

Frozen inventory is frozen cash, and it’s time to get a firm grasp on where it’s stalling out and why. Your profitability depends on it.

Where Amazon freezes your cash: aged, stranded and reserved inventory

If inventory represents cash you’ve already spent, let’s find out where some of that cash could be hiding. I don’t know everything, but I strongly believe every operator looking to improve P&L should watch these three areas: aging inventory, stranded inventory, and reserved inventory.

Aged inventory and the aged inventory surcharge

It’s no secret that most Amazon sellers struggle with aging inventory. Maybe you run a tight restocking schedule to avoid low-inventory fees and end up with too much overlap. Or maybe you’re dealing with market saturation because of a demand-forecasting error. Either way, units that sit for longer than 181 days (about six months) can become a big cash problem.

You can find your aged inventory in the FBA Inventory tool, which flags the ASINs that are already subject to the surcharge or will be within 60 days.

Since January 16, 2026, the Amazon aged inventory surcharge rates are as follows (assessed on the 15th of each month, on top of monthly storage fees):

• 181–210 days: $0.50 per cubic foot

• 211–240 days: $1.00 per cubic foot

• 241–270 days: $1.50 per cubic foot

• 271–300 days: $5.45 per cubic foot

• 301–330 days: $5.70 per cubic foot

• 331–365 days: $5.90 per cubic foot

• 366–455 days: $6.90 per cubic foot or $0.30 per unit, whichever is greater

• 456 days or more: $7.90 per cubic foot or $0.35 per unit, whichever is greater

Clothing, shoes, bags, jewelry and watches are exempt from the 181–270 day tiers.

These charges add up fast, especially when combined with peak season storage fees. Let’s do some basic unit economics: Say you’ve been storing 15 cubic feet of compression socks at an FC for about $12/month ($0.78 base storage). Once October hits, the peak rate kicks in and that number jumps to $36/month ($2.40 base storage). Now add the 181–210 day aged inventory surcharge of $0.50 per cubic foot, and that $12 becomes $43.50. Bigger accounts pay more on top: once you average 25 or more cubic feet a day and hold more than 22 weeks of supply, Amazon adds a storage utilization surcharge starting at $0.44 per cubic foot.

Aged inventory often intersects with excess inventory as well, so you’re not just incurring exponential fees with stuck units; you may also be hurting your Inventory Performance Index (IPI). Additionally, food, supplements, and any aged items with an expiration date become a compounded problem because these units have to be destroyed. That cash is no longer just delayed. It’s gone.

Amazon’s own suggestions are an Outlet deal (minimum 20% discount) or a removal order. Submit the removal by 11:59 p.m. PT on the 14th and those units skip that month’s surcharge. Whether you want to weigh surcharge fees against the possibility of a larger profit in the Q4 rush is up to you, but we’ll dive more into strategy later.

The main takeaway here is: aged inventory is a critical spot for frozen cash. Pay close attention to the number of aged units you have before a reorder.

Stranded inventory

Another common spot for frozen cash is stranded inventory. This includes any product stored in an Amazon Fulfillment Center without an active listing. Sometimes, stranded inventory results from a simple user error, like accidentally archiving a product or switching it from FBA to FBM. Other times, you have to dig through the Fix stranded inventory page to find out why your stock is inactive.

Amazon lists 30+ possible reasons for a Stranded designation, including Miscategorized ASIN, Restricted ASIN, Missing SKU, and Product recall.

Usually, stranded inventory fixes are quick and painless (and can even be done in bulk), but you might have to open a case with Selling Partner Support for unresolved issues. Also, enabling “auto-removal” gives Amazon permission to either dispose of stranded units or ship them back to your business address after a certain number of days. If you haven’t checked these settings recently, it’s definitely worth taking a look.

Regardless of the reason, these units aren’t doing you any favors. In fact, they incur storage fees, hurt your IPI, and can prevent you from restocking. You should receive notifications when units become Stranded, but I’ve seen brands operate for weeks on end before realizing a chunk of their inventory is stuck. Make the Fix Stranded Inventory page highly visible on your dashboard, just in case. You could be sitting on a pile of potential Q4 earnings.

Reserved inventory

The third place to check for frozen cash is in your Reserved Inventory report. Amazon lists three reasons a unit can sit in reserved status: a customer order (including orders still waiting on payment verification), FC processing (dimension checks, investigations, pending removals), and Staging, which Amazon describes as units temporarily held “to ensure optimal fulfillment speed.” Units moving between fulfillment centers no longer count as reserved; they stay available to buy.

The catch here is that Amazon sometimes takes longer than expected with processing, flags products for investigations you’re unaware of, or even loses units listed in Reserve. I recommend scheduling an automatically generated Reserved Inventory report every 7 days from your Schedule tab to monitor reserved SKUs. If something smells off, it probably is.

Payment verification alone can hold customer-order units for up to 21 days. If any of your reserved inventory has been sitting in this category for 30+ days during Q4, it’s time to escalate.

Building an Amazon inventory management strategy you can actually run

As a brand owner, you understand the importance of an Amazon inventory management strategy. The challenge is building one that lasts. As a founder and fellow operator, these are the boxes I always check before a reorder:

Step 1: Resolve aged inventory

Before peak season, I want to gather as much working capital as I can from my existing stock. I do find Outlet deals to be worth it occasionally, especially for items beyond the 270-day bucket. It can be a quick way to move units for cash. That said, I always check demand forecasts for specific SKUs. If it makes more sense to eat surcharge fees for another month, because I know holiday shoppers are coming, I’ll wait.

Step 2: Fix stranded inventory

Never move forward with a reorder without checking your stranded inventory first. If I have hundreds of units just waiting to be “unlocked” with a simple fix, those sales could carry a lot of weight propping up my business for the busy season. I also need to get rid of any dead stock storage fees ASAP.

Step 3: Track reserved inventory

Rather than taking my Reserve number at face value, I’m going to investigate it. How many units are in customer reserve, and what will the net margin be once they’re out? I’ll also cross-reference every SKU that's been in reserve for more than a couple of weeks. If I find items Amazon has lost or forgotten about, that’s even more cash flow for Q4.

Step 4: Order based on total estimated working capital

Once I know how much take-home to expect from these inventory categories, I have a much clearer picture of my buying power. I add these inventory cash flow estimates plus my current bottom line, and use that number to inform my order.

And that’s pretty much it. Eliminate unnecessary fees, find frozen funds, and make inventory decisions with confidence. Of course, so much more goes into operating an eCommerce business, but this inventory checklist is a huge part of my strategy, and it always helps me prepare for a big reorder.
