This page teaches how to set a working rule that decides, order by order, whether a specific store is allowed to fulfill a specific online order from its own shelf stock, for a retail buyer who has already sized each store's own shareable pool. Lesson 4.1 decided how much stock a store may share; this lesson decides when a specific online order actually draws on that shared pool. This lesson mainly teaches a decision, applied every time an online order arrives.
A retailer that lets every online order in a region default to the nearest store's own shelf, without a stated rule, risks a store's own staff spending unplanned time picking and packing instead of serving walk-in customers, and risks the shared pool running out mid-day with no warning. A retailer that never lets a store fulfill from its own shelf at all misses genuine savings in shipping time and cost that a nearby store's own stock could otherwise provide.
You need: each store's own shareable pool from Lesson 4.1, and to know roughly how much staff time a store can spare for picking and packing an online order without disrupting its own shop-floor service.
By the end of this lesson you can:
Not covered here: sizing the shareable pool itself (Lesson 4.1), protecting that pool once online orders are running against it (Lesson 4.3), and choosing between a nearby store and a central warehouse for a specific order (Lesson 4.4).
| Term | Meaning |
|---|---|
| Ship-from-store | Fulfilling an online order by picking the item from a store's own shelf stock and shipping it to the customer, instead of from a central warehouse. |
| Fulfillment rule | A stated condition that decides whether a specific store is allowed to fulfill a specific online order from its own shelf. |
| Pick-and-pack time | The staff time a store spends finding and packing its own shelf stock for an online order, taken away from serving walk-in customers. |
| Shared inventory pool | The part of a retailer's own store stock that is shown as available and sold through both the store and its online channel. |
| Make to Order (MTO) | Production starts only after a specific buyer confirms a specific order. |
Having a shareable pool at a store, from Lesson 4.1, answers "how much stock may the online channel draw from this store," but it does not answer "should this specific store actually pick and ship this specific order right now." A fulfillment rule checks a small set of conditions, such as remaining shareable pool, current staff capacity for pick-and-pack time, and distance to the customer, before a ship-from-store decision is made; skipping this check and defaulting every order to the nearest store with any stock left can overload that store's own staff or empty its shared pool faster than planned.
| What can differ | The shapes you meet | Why it matters |
|---|---|---|
| Export vs. domestic customer distance | An export-facing order shipped from a store to a customer outside Fairway Stores' own home market usually costs more and takes longer than a domestic order a nearby store can reach quickly | A fulfillment rule may set a wider distance threshold for domestic orders than export ones, since the shipping cost and time trade-off differs |
| Make to Order stock vs. a reorderable Make to Stock line | A Make to Order style, like Fairway Stores' own T-shirt, has a fixed shareable pool that cannot easily be topped up mid-season, so its fulfillment rule needs a lower pool floor than a reorderable line | Applying the same fulfillment rule to MTO and reorderable stock risks emptying the harder-to-replace MTO pool faster than intended |
| A store with spare staff capacity vs. one already stretched | A quieter store can absorb pick-and-pack time for several online orders a day without affecting its own shop floor; a busy flagship store may only absorb a handful | A fulfillment rule that ignores staff capacity can turn ship-from-store into an unplanned burden on a store's own service |
| A single order vs. a batch of orders arriving together | A single online order is a simple check against the rule; a batch of orders arriving in the same hour needs the rule applied to each in turn, since fulfilling the first can change whether the rule is still satisfied for the next | A retailer that checks the rule once for a whole batch, rather than order by order, can approve orders that collectively breach the shareable pool or staff capacity |
| Product families | The same fulfillment-rule logic applies whether the stock is apparel, socks and hosiery, knit-to-garment, terry and towels, or home textiles and bedding | A retailer new to ship-from-store often starts with one product family before extending the same rule to others |
Fairway Stores' flagship store carries the 15,000-piece T-shirt order from Northline Apparel, made to order at Delta Garments, and its shareable pool, sized in Lesson 4.1, is 200 pieces. Fairway Stores' buyer now has to set a fulfillment rule for that store: at what remaining shareable pool level, staff capacity and customer distance does the flagship store actually pick and ship an online order from its own shelf, rather than the order being routed elsewhere.
The buyer wants a rule specific enough to apply automatically, order by order, not a manual decision repeated for every single online order the flagship store might receive.
The worked numberThe worked number shows a two-part rule at work: the flagship store stops fulfilling online orders from its own shelf once its shareable pool falls to 40 pieces, protecting the last part of the pool as a buffer, and separately stops once 15 orders have already been fulfilled that day, protecting staff time regardless of how much stock remains. Either condition alone would miss part of the risk; both together cover stock risk and staff-capacity risk at once.
A common mistake is writing a fulfillment rule around the shareable pool alone, assuming that as long as stock shows as available, the store can keep fulfilling online orders indefinitely. A store with plenty of shareable stock left can still be overloaded if pick-and-pack time for a run of online orders pulls staff away from the shop floor at a busy hour, which is a cost the stock-only rule never sees coming. The fix is a rule that checks staff capacity alongside the shareable pool, not stock alone.
Knowing how much stock a store can share with the online channel is not the same as knowing when that store should actually pick and ship a specific online order. A working rule checks the store's own remaining shareable stock and its own spare staff time before deciding. At Fairway Stores' flagship store, the rule stops ship-from-store once the shareable pool falls to 40 pieces, or once 15 online orders have already been fulfilled that day, whichever happens first. Checking stock alone would miss the staff-capacity risk that can overload a store even while stock still shows as available.
Mona, the merchandiser at Delta Garments who tracks Fairway Stores' own T-shirt order, notices the flagship store's own reorders against remaining stock have become frequent and small, a pattern consistent with a busy online fulfillment day rather than shop-floor selling alone. She flags this to Fairway Stores' buyer and mentions that a regional manager has separately asked whether the flagship store can keep fulfilling online orders past its own daily cap of 15, since its shareable pool still shows 80 pieces. The facts in front of the buyer:
The message passed on by Mona:
Should the buyer approve fulfilling two more orders from the flagship store today, since stock is still available? Decide before you open the decision.
No, the flagship store should not take two more orders today; the daily cap protects staff capacity, a separate limit from remaining stock.
Two facts decide this. First, this lesson's own rule sets two separate conditions, a stock floor and a staff-capacity cap, and reaching either one pauses fulfillment regardless of the other; the 80 pieces remaining satisfies the stock floor but does not override the staff-capacity cap already reached. Second, this lesson's own trap warns exactly against checking stock alone; approving two more orders because stock looks available repeats that mistake and risks pulling staff from shop-floor service at a busy store.
Routing the two orders to a different store with spare capacity, or to a central warehouse, remains available; the point is that the flagship store's own daily cap should not be overridden simply because its shareable pool still shows stock.
The USD 48.60 figure is a working estimate, not a guaranteed loss, since not every minute of pick-and-pack time necessarily displaces a shop-floor sale. It illustrates why a daily cap set for staff capacity should not be waived just because the stock floor has not yet been reached, since the two limits protect against different risks.

1. Why is a shareable pool alone not enough to decide whether a store should fulfill a specific online order?
2. A store's shareable pool is 150 pieces with a 20% fulfillment floor, and it has already fulfilled 15 of its 15-order daily cap. Should it fulfill one more order?
3. Why might an export-facing online order need a different distance threshold in a fulfillment rule than a domestic order?

You now know how to set a rule that decides whether a store fulfills a specific online order. The next lesson adds the protection this rule needs once online orders are actually being fulfilled, so the shareable pool itself is never quietly emptied below a safe floor. Back to the course map
