Click and collect, ship from store, endless aisle: choosing your omnichannel fulfilment model

Selling online is easy. Fulfilling it is the business

Putting a catalogue online takes weeks. Getting the right item, at the right quality, to the right customer at an acceptable cost takes operational discipline. That is the difference between omnichannel as a slogan and omnichannel as a profitable channel.

The fulfilment model you pick shapes your costs, the staff you need and how customers feel about you. These are the main options.

The five models

Model	How it works	Best when	Main challenge
Click and collect	Customer orders and pays, then collects from a store	Stores are close to customers, and you want low delivery cost	Picking quickly and keeping a staging area tidy
Curbside pickup	Staff bring the order to the customer's vehicle	Parking is available and customers value convenience	Staffing at peak times and timing the handover
Delivery from store	A rider or courier delivers from the nearest branch	Dense urban areas, grocery and convenience	Delivery cost and delivery windows
Ship from store	Stores ship parcels when stock is not at a warehouse	Spread inventory, longer-range items	Packing standards and carrier handling
Endless aisle	Staff or customers order items that are not on the shelf, from another branch or warehouse	Wide ranges and specialist stock	Clear lead times and transfer tracking

Most retailers use a mix. A supermarket may offer click and collect and local delivery. A hardware chain may add endless aisle for bulky items.

Stock accuracy comes first

Every model above promises something about availability. If your system shows ten units and the shelf has two, you will cancel orders, disappoint customers and waste labour. Before you scale omnichannel:

Run regular blind cycle counts on fast sellers.
Fix receiving discipline so stock is booked when it arrives.
Record damage, expiry and shrinkage promptly.
Show customers availability by store, not just a global total.

Our guide on reducing shrinkage covers the controls that keep stock records honest.

Order sourcing: which store fulfils which order

When an order can be fulfilled from several places, rules decide where it goes. Common factors:

Stock availability of every line in the order
Distance to the customer or the chosen pickup store
Cost, such as the cheapest delivery route
Capacity, so one branch is not swamped while another is idle
Freshness and expiry, which matters for perishables
Priority, such as same-day orders or high-value customers

Simple rules work well at the start: prefer the customer's chosen pickup store, then the nearest store with all items, then split the order. As volume grows, you can add cost and capacity into the rules.

Reserve stock when the order is placed

The most common omnichannel failure is overselling: two customers buy the last item, in different channels, at the same moment. The fix is stock reservation. When an order is placed and paid, the engine reserves the quantity at the chosen location. The reservation is released if the order is cancelled or not collected within the window. Without this, availability numbers are only guesses.

Picking, packing and handover

Operations decide whether the customer experience is good.

Pick on a handheld, guided by a route through the store, and scan every item.
Agree a substitution policy. Offer the closest alternative, ask permission when possible and never substitute allergen-sensitive items silently.
Keep chilled and frozen items cold. Use a separate staging area and time limits.
Set cut-off times and promise windows you can keep. A realistic window beats a fast one that fails.
Make handover simple. A clear collection point, a code or a QR, and staff who know where the order is.

Returns across channels

A customer may buy online and return in store, or buy in store and return by courier. Plan for it from the start:

Refund to the original tender, or issue store credit under clear rules
Restock the item to the right location, or mark it for inspection
Apply the same tax and fiscal handling as the original sale
Keep an audit trail linking the return to the original order

Count the cost

Omnichannel can destroy margin if you do not count what it costs. For each model, calculate:

Picking and packing labour per order
Packaging and delivery cost
Payment fees
Substitution and cancellation losses
Space used by staging

Compare that with the basket margin and any extra sales from new customers. Many retailers charge a delivery or service fee, set minimum order values or limit the hours when orders are accepted to protect economics.

Measure the right things

Measure	Why it matters
Order accuracy	Wrong or missing items drive refunds and churn
Pick time per order	Shows staffing and store-layout problems
Fill rate and substitution rate	Reveals stock accuracy
On-time collection or delivery	The promise customers remember
Cancellation rate	Often a sign of overselling
Cost per order	Tells you whether the channel pays
Repeat order rate	Shows whether customers are coming back

A practical rollout

Pick two or three strong stores with accurate stock and good space for a pickup point.
Launch click and collect with a limited range, clear cut-offs and a staging area.
Measure for four to six weeks and fix accuracy, speed and cost.
Add curbside or delivery where demand exists.
Extend to more stores and add ship from store or endless aisle for the right ranges.
Add channels, such as the app, web store and WhatsApp, on the same engine.
