Overstock Management: How to Stop Tying Up Cash in Excess Inventory

Overstock rarely comes from a single bad purchasing decision. It accumulates gradually through a combination of small optimistic choices. You order 20% extra because you got a better per-unit price at the higher MOQ. You bring in a new colourway because the supplier showed you a nice sample. You order based on last Q4's sales without accounting for the fact that you ran a 30% off promotion that inflated the numbers. Each decision seems reasonable in isolation. But across 150+ SKUs and 6-8 ordering cycles per year, these small optimistic biases compound into a significant overstock position. The average ecommerce brand carries 25-35% more inventory than it needs at any given time. For a brand turning over £500K annually with 30% COGS, that is £37,500-£52,500 in excess stock sitting in the warehouse.

The most dangerous aspect of overstock is invisible: opportunity cost. Every pound locked in excess inventory is a pound you cannot use for marketing, new product development, or — critically — purchasing stock for products that are actually selling well. This creates a vicious cycle. You are overstocked on slow movers, so your cash is tied up. Your fast movers start running low, but you cannot afford to reorder because your capital is locked in the slow stock. Your fast movers stockout. Revenue drops. Now you have even less cash to address the problem. Meanwhile, the slow-moving stock is depreciating — either literally (seasonal products losing relevance) or through storage costs eating into already-thin margins. Warehousing in the UK costs £5-15 per pallet per week. If you have 10 pallets of overstock, that is £50-150 per week in pure holding cost on products that are not generating revenue.

Bailey & Coco discovered their overstock problem when they analysed their weeks cover across all 2,845 SKUs. The results were stark: 340 SKUs (12% of their catalogue) had over 52 weeks cover — more than a year's supply at current sell-through rates. These SKUs represented £23,000 in tied-up capital. The worst offenders were seasonal products ordered at the wrong time: summer cooling bandanas ordered in bulk in April that arrived in August (after peak demand had passed), and limited-edition Christmas collar patterns from 2024 that sold well that year but had been reordered in 2025 on the assumption that demand would repeat. It did not — customers wanted the new 2025 patterns instead.

The overstock also included products where the minimum order quantity from their China supplier exceeded realistic demand. Their supplier required a minimum of 500 units per colourway. For niche patterns that sell 200 units per year, that meant 2.5 years of stock from a single order. The per-unit cost saving from hitting the MOQ was dwarfed by the carrying cost of 18 months of excess inventory.

If you already have overstock, the goal is to convert it back to cash as quickly as possible, even at a margin loss. The longer you hold it, the less it is worth.

Progressive discounting: Start at 20% off, move to 40% after 30 days, 60% after 60 days. This captures price-sensitive customers at each tier while maximising your recovery on units sold early.

Bundle with fast movers: Pair overstock items with popular products as a "bonus item" or "starter kit." This adds perceived value to the bundle while clearing dead inventory without visible discounting.

B2B liquidation: Companies like Zoro and B-Stock specialise in buying excess ecommerce inventory at 10-30% of retail price. The margin is painful but the cash recovery is immediate.

Donation with tax benefit: Donating excess stock to registered charities provides a tax deduction on the cost value of the goods. For products with no resale path, this is often the most economically rational option.

Marketplace channels: List overstock on Amazon, eBay, or TK Maxx Marketplace at discounted prices. Different customer base, different price expectations, and it keeps discounting off your main brand site.

Canopy's weeks cover dashboard makes overstock visible before it becomes a problem. Every SKU is colour-coded: red for critically low stock, green for healthy levels, and amber for approaching overstock territory. When you create a purchase order, Canopy shows you exactly where the new stock will take your weeks cover — before you submit the order. If adding 500 units of a pattern would push it from 10 weeks to 35 weeks cover, you see that warning before the order goes to your supplier. This pre-order visibility is the single most effective overstock prevention tool. Most overstock happens because founders did not have this information at the moment they were making the purchasing decision. They had it in a spreadsheet somewhere, or they could calculate it if they spent 30 minutes pulling reports, but not at the point of decision. Canopy puts it in front of you when it matters.
