How to Reduce Cash Tied Up in Inventory

A balance sheet calls inventory an asset. A bank account does not: every unit on the shelf is money that has already left, and it does not come back until someone buys the thing. That gap is why a store can be profitable on paper and still unable to fund the order it knows it should place.

This post covers three things in order: how to work out how much cash is actually tied up, how to release some of it from stock you already own, and how to stop the pile rebuilding itself over the next two buying cycles.

How much cash is actually tied up

Start with the number, because most stores have never calculated it. It is the sum, across every SKU, of units on hand multiplied by unit cost. Not retail price. Retail is what you hope to convert it into; cost is what left your account.

That total on its own is not very useful, because some of it is doing a job. Split it three ways. First, the cover you need: enough stock to sell through your supplier's lead time plus whatever buffer you have deliberately sized. Second, the cover you do not need, which is everything above that level. Third, stock that is not selling at any rate worth planning around.

Work it on one SKU. "Cedar & Fig, 250g" sells about 5 units a day, costs $7 a unit, and has a 12-day supplier lead time. Its target stock level is 240 units, which is 48 days of cover. There are 420 units in the warehouse.

That last figure, 36 extra days of cover on one candle, is the part of this SKU's cash you could have somewhere else. The per-unit method for arriving at it is in how to calculate excess inventory; this post is about what to do once you have the number. Run it across the catalog and the sum is the honest size of the problem.

There is a second number people reach for here, and it is worth being careful with. Holding stock costs you something beyond the purchase: storage, insurance, the interest or opportunity cost on the money, and the share of it that eventually gets written down. You will find that expressed as a tidy percentage of inventory value in a lot of places. Do not borrow one. Those figures come from warehouses and businesses that are not yours, and applying someone else's percentage to your stock produces a number with no evidence behind it. Build your own: add up what you actually paid last year for storage, financing and write-offs, and divide it by your average inventory value. Working out your own carrying cost takes that calculation component by component, and the inventory metrics guide has the formula. What write-downs mean for your tax position is a question for your accountant, not for a blog post.

The cash conversion cycle

The cash conversion cycle is the time between paying your supplier and being paid by your customer. For most Shopify stores the customer end is short: they pay at checkout and the payout lands a few days later. Almost all the length is on the other side.

Two consequences follow. Shortening the middle bar, the holding period, is the same thing as raising inventory turnover, and it releases cash without touching a single price. Moving the left-hand marker later, by negotiating payment terms, releases cash without touching a single unit. Neither one requires selling more.

Release cash from what you already hold

These are in order of what they cost you in margin, cheapest first. Most stores start at the bottom of this list, which is why the recovery hurts more than it needs to.

One thing not to raid: safety stock. It looks like idle cash and it is the cheapest place to find some, right up until a supplier slips and the buffer that would have covered it is gone. If the buffer is genuinely oversized, resize it deliberately against that SKU's own variability, the way the safety stock guide sets out. Do not spend it by accident.

Stop adding to the problem

A clear-out is a one-off. The pile rebuilds unless the ordering habits that built it change, and they are usually three.

Order quantities decided as round numbers rather than as days of cover. A minimum order quantity treated as a target instead of as the supplier's floor. And a price break taken on unit cost alone, without asking how long the extra units will sit: cheaper per unit and more expensive in total is an easy trade to make by accident. The overstocking prevention guide covers the ordering side of this in full.

The habit that holds all three together is checking, before every purchase order, how much cover the SKU already has. That takes a couple of minutes per line and stops happening somewhere around the point a catalog outgrows one person's memory. StockCue keeps the cover figure current per SKU from your own order history and applies MOQ and case-pack rounding to what it suggests you buy, with forecasting on every plan including Free. The buying planner and purchase orders start at Starter.

Supplier terms and order cadence

Two levers left, and they work on the cycle rather than on the stock.

Payment terms move the left-hand end of the timeline. Prepayment means your cash is gone before the goods exist; a deposit with the balance on shipment, or net terms with a supplier you have a track record with, moves the same purchase weeks later in the cycle without changing what you buy. Suppliers do not usually volunteer this. Ask after a few clean orders, when you have something to point at.

Cadence moves the middle. Splitting the same annual volume across more, smaller orders lowers your average stock level, and the cash standing behind it drops in proportion. The bill is more freight, more admin, and losing access to volume breaks or falling under a minimum order value. How often you should reorder works through that trade-off properly, including the cases where it is not worth making.

Neither lever sells one more unit. Both change how much of your money has to sit still while the units that do sell make their way through.

Frequently Asked Questions

How much cash should be tied up in inventory?

There is no defensible general answer, and any single percentage quoted for stores at large was measured on a different kind of business. The version you can actually use is built from your own numbers: the stock you need to cover demand through your lead time plus your buffer is working capital doing its job, and everything above that level is cash sitting still. Calculate the second figure per SKU and you have a target that belongs to your store rather than to someone else's.

What is the cash conversion cycle?

It is the stretch of time between paying your supplier for stock and collecting the money from the customer who eventually buys it. For a Shopify store, the customer pays at checkout and the payout follows a few days later, so the cycle is dominated by two things you influence: when your supplier requires payment, and how long the stock sits before it sells. The longer that stretch, the more cash you need standing behind the same level of sales.

How do you free up cash from inventory without discounting?

The largest lever is a decision not to spend: stop reordering the SKUs that are not moving and let the existing units sell through at full price. After that, redirect the next order's budget from over-covered products toward the ones that are actually short, check whether your supplier accepts returns or exchanges on unsold stock, and bundle slow units with fast ones so they leave at close to full margin. Discounting works, but it is the lever that costs the most margin, so it belongs last rather than first.

Does ordering more often improve cash flow?

Usually yes, in the sense that smaller, more frequent orders lower the average amount of stock you are holding at any moment, which lowers the cash standing behind it. What it costs is more freight, more supplier admin, and less access to volume price breaks or a supplier's minimum order quantity. Whether the trade is worth it depends on the size of those costs against how tight your cash actually is.
