Boutique Inventory Management: What to Reorder, Hold, Mark Down or Exit

Buying the inventory was the easy part. The money is made or lost in what you do after it lands: which styles you reorder, which you leave alone, which you discount, and which you finally let go of. This guide is the decision system for inventory you already own.

I'm Carina — boutique owner since 2013, Shopify Partner, and coach to 3,000+ Shopify boutique owners. Below is the lifecycle I walk owners through: measure, reorder, afford, hold, mark down, exit — plus the tracking that makes each call possible.

The inventory decision map

Every style you own sits in one of four places. Start here, then read the section that matches.

• Selling quickly → evaluate a reorder → then check whether your open-to-buy has room for it.
• Selling steadily → hold and watch → keep an eye on weeks of supply against vendor lead time.
• Slowing down → review season remaining and margin → consider a markdown.
• Stopped moving → stop waiting → run the exit options.

None of these are automatic. The same numbers read differently on a seasonal piece, a core basic, and a style you bought too deep on. The point is to put each style in a lane on purpose instead of letting the slow ones drift.

1. Measure what's actually selling

You can't make any of the calls below without a weekly number per style. A clean Google Sheet does this for stores under roughly $300K:

• SKU / product name
• Vendor
• Date received
• Units received
• Wholesale cost per unit
• Retail price
• Units sold (update weekly from Shopify)
• Units on hand (auto-calculated)
• Sell-through % (units sold ÷ units received)
• Rate of sale (units sold ÷ weeks in stock)

Update once a week and sort by sell-through, then sort again by rate of sale. The two lists are not identical, and the gap between them is where you bought too deep.

Sell-through, briefly

Sell-through % = units sold ÷ units received × 100, always over a stated window. It tells you what proportion of a buy has cleared — nothing more. It doesn't tell you how fast the remaining units will go, and there is no universal percentage that means "winner." The full formula, the measurement window, and the reorder framework live in sell-through rate for boutiques, and the Sell-Through & Reorder Calculator runs a single style for you. I won't repeat that math here.

2. How to decide what to reorder

A reorder case is built from several factors together, not one percentage:

• Sell-through — how much of the original buy has cleared, over a window you state.
• Rate of sale — units per week, which is what actually projects forward.
• Weeks of supply — units on hand ÷ rate of sale. This is the number that decides urgency.
• Vendor lead time — if weeks of supply is shorter than the time the vendor needs, waiting to decide is itself a decision.
• Full-price vs markdown-dependent — units that only moved after a discount prove demand at the sale price, not at your intended price. Separate those before you call it a winner.
• Seasonality — a reorder only makes sense if there's selling time on the other side of it.
• Supplier availability — the strongest reorder case is worthless if the vendor's cut off or out of the colorway.

Run a style through the Sell-Through & Reorder Calculator to see weeks of supply against your lead time before you commit.

3. Just because it deserves a reorder doesn't mean you can afford it

These are two separate questions and owners collapse them constantly:

• Sell-through tells you what deserves the money.
• Open-to-buy tells you how much buying room actually exists.

A style can earn a reorder and still not get one this month, because the cash is committed to orders already placed or to inventory you need on the floor at month-end. Set open-to-buy monthly: open-to-buy for small boutiques explains the formula, and the open-to-buy calculator runs it. If the number comes back tight, the reorder list becomes a ranking exercise rather than a shopping list.

4. What to hold

Holding is an active choice, not the absence of one. A style is usually worth holding at full price when it's still moving at a consistent rate, when the remaining units will clear inside the selling time left, and when depth is low enough that the cash tied up isn't blocking anything better. Set a date to look again — the risk with holding is that "watch it" quietly becomes "forget it."

5. When should you consider a markdown?

There's no day count that makes a markdown correct. Weigh these instead:

• Rate of sale is slowing — compare the last two weeks to the two before them. A falling rate means your remaining units will take longer than the average suggests.
• Season remaining — if the selling window closes before the stock clears at the current rate, discounting inside the season usually beats carrying it past the season.
• Weeks of supply — deep inventory on a slowing style is a different problem than two units left.
• Margin impact — know what the discount costs per unit before you set it, not after.
• Whether it's blocking better buys — cash sitting in this style is cash not buying the one that's selling out.

The markdown & sale calculator shows the financial side: sale price, gross profit given up per unit, and how many discounted units it takes to match one full-price sale. If the item never had enough margin to discount comfortably, that's a pricing problem — check it in the profit margin calculator.

6. How to think about inventory age

Days in stock only means something relative to your own business. Judge age against:

• Season length — 45 days is nothing on a core basic and most of the window on a holiday piece.
• Vendor lead time — if a replenishment cycle has come and gone without a reorder case forming, that's information.
• Normal selling cycle for the category — occasion dresses, denim, and impulse accessories don't clear on the same clock.
• Current rate of sale — an old style that's still moving steadily is not the same as an old style that's stopped.

Skip the universal day-30 / day-60 / day-90 schedule. It will mark down things that were always going to take longer and leave alone things that died in week two.

7. Exiting true dead stock

Dead stock isn't a day count — it's a pattern. Treat a style as finished when several of these are true at once:

• A full replenishment cycle has elapsed with no reorder case forming
• The selling season for it has largely or entirely passed
• Movement is negligible, not just slow
• It only moves when you promote it, and it stalls again after
• You would not buy it again at any price

Once it's there, stop waiting for it to magically sell. Options, in order of preference:

1. Bundle 2–3 dead pieces together at a sharp price ("Mystery Box: 3 dresses for $45")
2. Run a private "VIP loyalty sale" — email-list only, deeply discounted
3. Offer as gift-with-purchase over a spend threshold
4. Donate to a charity that matches your customer (write off the wholesale cost)
5. Wholesale-out to a clearance reseller (last resort — expect cents on the dollar)

The opportunity cost of storing dead stock is bigger than the discount. Move it, then look at the vendor: one supplier can quietly account for most of your dead stock, which is a buying decision, not a clearance one.

8. Inventory turn, and what it actually tells you

Inventory turn is how many times you sell through your average inventory in a year (cost of goods sold ÷ average inventory at cost). It's a whole-business health read, not a per-style one: a low turn means a lot of your cash is sitting still, a high turn means your cash is recycling quickly but you may be stocking out on winners.

Ignore borrowed "healthy retail" targets. Turn varies enormously by category, price point, and business model — a $19 accessories mix and a $180 occasion-dress mix should not turn at the same speed. What's useful is your own trend: compare this quarter to the same quarter last year, and watch whether turn is improving as you get better at the reorder and markdown calls above.

9. The rest of the numbers worth watching

• Days on hand — average days a unit sits before selling. Useful directionally, per category.
• Gross margin % — (retail − landed cost) ÷ retail, per style. This sets how much markdown room you actually have.
• Stockout rate — how often your top sellers are unavailable. Every stockout is a sale the rate-of-sale data will never show you.
• Sell-through by vendor — the fastest way to see who deserves more of the budget next season.
• Open-to-buy — set monthly, before market, not after.

10. The review cadence and the tools behind it

Weekly: update units sold, re-sort by rate of sale, and move anything that changed lanes on the decision map. Monthly: set open-to-buy. Quarterly: do a real physical count — your Shopify numbers drift, and you don't want to make buying decisions on drifted data.

On tooling: Shopify's built-in tracking plus the spreadsheet above is genuinely enough under roughly 200 SKUs on a single channel. You graduate to an app when you're selling in person and online and constantly out of sync, when you add channels (Etsy, Amazon, TikTok Shop, wholesale), or when the spreadsheet stops getting updated. Then: Stocky (free with Shopify POS Pro, best if you have a physical location), Sortly (from $29/mo, lightest "real" app), Trunk (from $35/mo, multi-channel sync), and Inventory Planner or Katana only once forecasting errors are costing you real money.

Storage still matters to the decisions: label shelves by category then SKU range, keep the top 20 sellers accessible, photograph new arrivals the day they land, and process returns back into inventory within 48 hours — untracked stock can't be measured, and unmeasured stock becomes dead stock by default.

Your next step

Pick your slowest ten styles this week and put each one in a lane: reorder, hold, mark down, exit. Then run the reorder candidates through the Sell-Through & Reorder Calculator and check the budget in the open-to-buy calculator.

If footwear is part of the assortment, track it separately from apparel: preset packs and size-level sell-through can hide slow inventory inside an otherwise successful style. Use this shoe case-pack and size-run planning guide before setting the first shoe reorder point.

Sizing a buy that hasn't been placed yet is a different job — the Boutique Inventory Buy Planner handles the before, and how much inventory to start a boutique covers the very first order.

If you want me to look at how your inventory is currently set up, the Boutique Store Audit covers it.

Inventory is boring. Review it weekly and it stops eating your cash.
