What is a dark store?

It is called “dark” because the shop floor is closed to the public: there are no customers, tills or displays, and the shelves are laid out for pickers, not shoppers.

How a brand’s stock reaches a dark store

Brands rarely deliver to dark stores themselves. Stock usually travels in two legs:

1. Brand to platform warehouse. The platform raises a vendor PO. The brand picks, packs and delivers to the platform’s larger city warehouse (often called a mother hub), where it is checked and recorded on a GRN.
2. Platform warehouse to dark stores. The platform splits that stock across its dark stores by each store’s sales, usually in frequent small transfers.
3. Dark store to buyer. When an order comes in, a picker collects it from the shelves in minutes and a rider delivers it.

So a brand’s PO is the sum of many small, store-level demands. That is why quick commerce POs can swing week to week.

Dark store, warehouse, micro-fulfilment centre and mother hub compared

Facility	What it does	Size and range	Open to shoppers?
Dark store	Picks online orders for delivery in minutes to nearby buyers	Small, narrow fast-moving range	No
Warehouse or fulfilment centre	Stores bulk stock and ships orders or replenishment over a wide area	Large, wide range	No
Micro-fulfilment centre (MFC)	A small fulfilment site in or near a city, often with more automation, sometimes attached to a store	Small to medium	Usually no
Mother hub	A platform’s city warehouse that receives brand stock and replenishes its dark stores	Medium to large	No
Retail store	Sells over the counter; may also pick online orders	Varies	Yes

The terms overlap: some companies use “dark store” and “micro-fulfilment centre” for the same kind of site.

Example: from one dark store’s shelf to the brand’s PO. One SKU sells about 12 units a day at a dark store. If the platform aims to hold 4 days of cover at the store, its target is 48 units; with 20 on the shelf, it sends 28 more from the mother hub. Now scale up: 40 dark stores in a city averaging 12 units a day is 480 units a day. If the mother hub keeps 7 days of cover (3,360 units) and holds 2,000, its next PO to the brand is about 1,360 units. All figures are illustrative; each platform sets its own cover targets.

Common mistakes

• Reading one PO as steady demand. Store-level sales roll up into POs that swing; plan stock on the trend, not one order.
• Sending short-dated stock. Dark stores turn stock fast but can’t sell expired goods. Pick batches by expiry using FEFO.
• Unscannable cartons and units. Missing or wrong barcodes slow inward at the platform warehouse and can lead to rejection.
• Ignoring the platform’s GRN. It, not your dispatch note, says what was accepted and what you are paid for.

Related metrics

• Days of cover = stock on hand ÷ average daily sales. Example: 20 ÷ 12 = 1.7 days at the store in the example.
• On-shelf availability = store-days the SKU was in stock ÷ store-days it was listed.
• Sell-through = units sold ÷ units received, over a period.

Dark stores in the Indian context

• Quick-commerce platforms run them. In Indian cities, dark stores are mostly operated by quick-commerce platforms. A brand supplies the platform; the platform runs the store. Each platform agrees its own vendor terms, so confirm them with its partner team.
• Dated goods. Food labels carry “Date of manufacture or packaging” and “Expiry/Use by” under the FSS (Labelling and Display) Regulations, 2020 (regulation 5(10)). If a platform sets a minimum remaining shelf life for stock it receives, choose batches to meet it before dispatch.
• E-way bills on the first leg. CBIC’s e-way bill guide says an e-way bill is generated for movement of goods of consignment value more than ₹50,000, whether the movement is a supply or not. A replenishment consignment above that value needs one when it moves between states; for movement within a state, some states set a higher limit, so check your state’s rule.
