Retail Stock Replenishment: Keeping Best-Sellers Available Without Overbuying
A promotion makes a denim style look like a best-seller. The next refill follows that sales spike, but by the time it arrives demand has fallen back. The store now has more stock than it needs. Merchmix is a retail planning platform; Core Plus connects replenishment rules, store needs and the stock available to supply them.
INSIDE MERCHMIX / CORE PLUS
A best-seller changes.
Does its refill?
Follow Bulk refill from the style list into the store-by-size model matrix. Compare the rule with current stock and incoming supply.

Bulk refill
Find the style and check its replenishment rule.
The range has three apparel styles. An unassigned rule is a question to resolve, not a refill quantity.
THE KEY IDEA
Check the demand after the promotion, the stock already due and the gap before arrival. Replenish that need rather than repeat the best week’s sales.
The best-seller trap: replenishing yesterday’s spike
In this example, City sells 40 Straight Denim units during a promotion. Normal demand then returns to 20 a week, but another 40-unit refill is still being considered. The earlier selling rate has become an assumption that nobody has challenged.
City holds eight units and already has twelve due Thursday. Over a week, eight on hand plus twelve due equals the twenty units of expected demand. Adding the extra forty would leave forty units after twenty sales, before other movements. That is two more weeks of stock at the normal rate.
The weekly total is not the whole answer. Assume Thursday’s delivery is four days away and demand is spread evenly. Four days needs about twelve units, rounded up from 20 ÷ 7 × 4. Eight on hand leaves a four-unit timing gap. The task is to bridge that gap, not repeat the promotional refill.
Separate sustained demand from a short event
A spike is a reason to investigate. Check the promotion dates, price and availability before using the selling rate for another refill. A popular item can still be overbought when the quantity assumes the promotion will continue.
In Core Plus, establish the style, store and sizes before choosing the replenishment basis. The refill workspace makes the current rule visible. If that rule no longer fits the selling pattern, change the policy deliberately rather than leave the next run to repeat the old assumption.
For the denim example, the relevant rate is the assumed twenty units after the promotion. The forty-unit promotional result explains why the refill needs attention; it is not itself an instruction to send forty more.
AN APPAREL PLANNING SCENARIO
A 40-unit sales spike becomes a 40-unit surplus
City sells forty denim units in a promotion, then returns to twenty a week. It holds eight and has twelve due Thursday. Over the week, 8 + 12 − 20 leaves zero before other movements. Adding another forty-unit refill would leave forty. The timing still matters: with delivery four days away, even daily demand needs about twelve units before arrival, leaving a four-unit gap against the eight held. A bridge transfer is a different decision from repeating the forty-unit refill.
Illustrative situation, not a customer case study.Check the stock already due before adding another refill
For City, the twelve units due Thursday belong in the supply calculation. Check their current status and expected arrival before placing another order. Do not count a late receipt as stock available today.
The timing gap is a separate question. An illustrative four-unit transfer could bridge it if the correct sizes can arrive before the existing stock runs out. A nearby support store holds twenty units and sells four a week; releasing four would leave sixteen, or four weeks of cover, assuming no sales during the move.
Check that source position and transit timing before approving a supported action. If the transfer cannot arrive in time, it does not solve the gap simply because the quantities add up.
Use Bulk refill to find the rule behind the quantity
Core Plus Bulk refill lists styles, on-hand stock, size counts and replenishment rules. Open a style to inspect Properties, Size Detail, Stores and Summary. Those panels help establish which stock and policy the next decision concerns.
The screen animation uses warehouse stock: 120 Straight Denim units, 48 Everyday Knits and twelve Summer Dresses. The denim’s size breakdown is thirty small, sixty medium and thirty large units. These source quantities are different from City’s eight units already on hand.
A style without a replenishment rule needs a deliberate decision. It might need a rule for continuing trade or No Refill for an exit plan. Do not treat missing configuration as an instruction to top up every store.
Choose a model that fits the store and selling window
Rate of Sale uses the selling rate as a replenishment basis. It is a useful question for a continuing style after checking that recent sales represent ongoing demand. In the example, check the return to twenty units rather than preserve the promotion’s forty.
Safety Stock Buffer provides a buffer-based approach; establish the intended protection and applicable settings. Demand Curve Refill concerns the shape of expected demand over time. Neither model name removes the need to check current stock and confirmed incoming quantities.
No Refill can fit a product that is deliberately leaving the range. The Core Plus interface assigns models by store and size, so City and Outlet do not have to use the same policy. Check the size cells before saving a change; the demonstration only illustrates a draft selection.
FROM THE SIGNAL TO THE MERCHMIX DECISION
What to check before the next action
| What you see | Where to look in Merchmix | The decision to review |
|---|---|---|
| Promotion: 40 sold; ongoing demand: 20 a week | Core Plus / style and replenishment model | Use a demand basis that reflects the post-promotion selling rate. |
| 8 on hand + 12 due − 20 weekly sales = 0 | Store stock and confirmed incoming supply | Do not add another 40 simply because the promotion sold 40. |
| Four-day need: about 12; on hand: 8 | Yukti / supported transfer proposal | Check a four-unit bridge and its arrival time before approving. |
Compare the model with the store’s physical stock
The style workspace includes Model, CSOH and Sell-Through Rate views. CSOH means current stock on hand. Switching views lets the team compare the rule with the units actually held rather than interpret the model badge as the stock position.
In the matrix, City holds two small, four medium and two large denim units, totalling eight. Neighbourhood holds twenty-four and Outlet twelve. Those are location-specific positions, not a reason to distribute the warehouse’s 120 units evenly.
When demand changes, check the affected stores and sizes first. A policy adjustment for City should not silently become a refill instruction for Outlet, especially if Outlet’s selling plan calls for No Refill.
Use Yukti to propose the smaller, timely response
Yukti is the assistant inside Merchmix. It helps identify a stock problem and prepares supported actions for a person to approve. Available actions depend on connected capabilities and the user’s permissions.
For this example, the Yukti conversation explains the twelve units due Thursday and City’s four-unit timing gap. It proposes a four-unit bridge transfer, split one small, two medium and one large, rather than another forty-unit refill.
The planner checks the source, sizes and arrival time before approving the supported move. A transfer proposal is not a confirmed receipt. Keep the authorised action and its operational status connected to the supply question it is meant to solve.
Measure whether the refill solved the right problem
After the supply progresses, check City’s availability and whether the promotional quantity has been removed from the next decision. The aim is to serve the current twenty-unit rate without rebuilding a forty-unit surplus.
Keep the arrival of Thursday’s twelve units separate from the proposed four-unit bridge. Confirm what actually arrived, then use current stock and sales for the next replenishment calculation.
Retail stock replenishment works when the quantity follows the present need. Core Plus makes the store and size policy visible; Yukti can prepare a supported response for approval. The planner still needs to decide whether that response arrives in time and fits the selling window.
BEFORE REPEATING THE PROMOTIONAL REFILL
- Is demand sustained, or is a temporary uplift driving the alert?
- What stock is already due, and when will it be available?
- Does the proposed refill fit the remaining selling window?
- Does the replenishment rule still fit this product and store?
- Did the last refill protect availability or leave excess?
A CLEARER NEXT STEP
Common questions
Why can replenishing a best-seller create excess stock?
A short event can inflate the rate used for the next refill. In this illustration, a forty-unit promotional week falls back to twenty. Sending another forty on top of the eight held and twelve due leaves forty after twenty sales, before other movements.
What does CSOH mean in the refill screen?
CSOH means current stock on hand. In the store-size matrix, City holds two small, four medium and two large denim units. Those eight units are separate from warehouse stock and confirmed quantities still due.
Does the animation save a replenishment rule or create a transfer?
No. The screen sequence uses data and shows a draft model choice. The Yukti example presents a four-unit bridge transfer for a person to approve. Neither illustration writes to a live Merchmix system.
THE DECISION TRAIL / YUKTI
A refill with a reason.
A response with limits.
Yukti includes the twelve units already due, explains the four-unit timing gap and proposes a smaller bridge for approval. The promotional sales spike does not become another forty-unit order.
- 01Understand the exception
Check the demand behind the low-stock signal.
- 02Check incoming supply
Check the twelve units due and the four-unit bridge proposal.
- 03Close the loop
Confirm receipt before counting stock as available.
FROM CURRENT DEMAND TO THE RIGHT REFILL
Keep the best-seller.
Lose the excess.
Check the demand after the promotion, the stock already due and the gap before arrival. Replenish that need rather than repeat the best week’s sales.
