Multichannel
Multichannel (multi-channel selling) describes selling in parallel across several largely separately managed sales channels – such as your own online shop, marketplaces, the brick-and-mortar store and phone sales. The goal is to reach customers where they shop, with each channel potentially running its own processes, stock and, in some cases, its own prices.
Multichannel (multi-channel selling) describes a sales strategy in which a company sells its products in parallel across several sales channels – for example through its own online shop, marketplaces such as Amazon or eBay, a physical retail store and classic phone or catalog sales. Each of these channels potentially addresses different customer groups and is often run largely independently. The basic idea: whoever is present on more channels reaches more customers and becomes less dependent on any single sales route.
What is characteristic of multichannel is that the channels exist side by side but are not necessarily interlinked. Each channel can have its own processes, its own prices, its own assortments and even its own stock. A customer who buys online and a customer who buys in the store are often treated as separate transactions. It is precisely this separation that marks the difference from the omnichannel approach, which merges the channels into a seamless shopping experience. Multichannel is therefore the starting stage of cross-channel commerce – broad in reach, but not yet fully integrated.
At a glance
- Parallel selling across several, usually separately managed channels (shop, marketplace, store, phone)
- Goal: greater reach and independence from any single sales route
- Channels can have their own prices, assortments and stock
- Distinction: with omnichannel the channels are fully integrated and share data
- Central challenge: keeping stock and orders in sync across all channels – a job for the ERP
What does multichannel mean in retail?
Multichannel describes a company's deliberate decision to offer the same or similar products across more than one sales channel. A channel here is any touchpoint through which a purchase happens: your own web shop, an online marketplace, the store, the field sales team, phone sales or a social commerce channel. Instead of relying on a single route, the company spreads its offering across the portfolio and thereby increases the number of contact points with potential buyers.
The motivation behind it is usually twofold: reach and risk diversification. On a marketplace a retailer reaches millions of visitors it would never address through its own shop; the retail store captures local walk-in customers. At the same time dependency drops – if one channel falls away, for example through a suspension of the marketplace account or seasonal fluctuations, the remaining channels keep revenue going. This robustness is an important strategic argument, especially for small and medium-sized retailers.
How multichannel works: channels and building blocks
A multichannel setup consists of the individual sales channels and the infrastructure behind them. The channels typically include your own online shop built on a shop system, one or more marketplaces, the physical store with a point-of-sale system, and B2B channels such as phone or quotation sales. Each channel has its own requirements for product presentation, data formats and commission models.
For the same products to appear consistently across all channels, unified product data is needed. A PIM (Product Information Management) maintains texts, attributes and images centrally and delivers them to each channel in the right format. The channels are connected via interfaces: orders from the shop and marketplaces flow into a lead system, from which stock and prices are reported back. Without this technical bracket, isolated solutions arise that must be maintained manually – error-prone and not scalable.
Typical channels at a glance
The most common multichannel channels include: your own online shop as a brand-owned channel with full control over presentation and customer data; marketplaces such as Amazon, eBay, Otto or Kaufland with high reach but commissions and strong competition; the physical retail store for local customers and advice; as well as classic direct channels such as phone, catalog or B2B field sales. Increasingly, social commerce channels are added, through which selling happens directly out of social networks.
Why multichannel matters – benefits and limits
The central benefit of multichannel lies in extended reach: every additional channel opens up new customer segments and buying situations. Customers today expect to be able to find a product where they already are – on the marketplace, in the shop or in the store. Whoever serves only one channel gives away revenue potential and hands reach over to the competition.
The opportunities come with challenges. More channels mean more complexity: stock must be kept in sync across all channels, otherwise overselling looms when the same item is sold simultaneously in the shop and on the marketplace. Prices, assortments and product data need to be maintained consistently, and orders from different channels processed uniformly. Without central control, the manual effort grows with every channel – this is where it is decided whether multichannel scales profitably or ends in maintenance chaos.
Multichannel in the ERP system
In multichannel retail the ERP system is the central hub that brings all channels together. It holds the shared data foundation – item master, stock, customers and orders – and ensures that every channel accesses the same, up-to-date stock. When a channel sells a product, the ERP posts the stock down and reports the new availability back to all other channels. This prevents overselling, which in multichannel operations would otherwise lead to cancellations and poor reviews.
Via interfaces, the ERP connects shop systems, marketplaces and, in some cases, point-of-sale systems. Orders converge channel-independently in a unified order processing flow: picking, shipping, invoicing and returns follow the same process, no matter which channel the order came from. This drastically reduces manual effort and makes the business scalable. Many ERP and merchandise management systems are designed specifically for this multi-channel selling and come with ready-made connectors to common shops and marketplaces.
Inventory management as the critical point
Cross-channel inventory management is the nerve center of every multichannel setup. Available stock must be mirrored to all channels in real time or near real time. If the marketplace sells the last unit, the shop must immediately mark it as "unavailable". Advanced systems additionally allow stock to be allocated deliberately to channels – for example holding back a safety buffer for the retail store or assigning marketplaces only part of the stock to cushion overselling.
Distinction: multichannel, omnichannel and cross-channel
Multichannel, cross-channel and omnichannel describe stages of increasing channel integration and are often confused. With multichannel the channels exist side by side but are largely separate from one another: a customer moves within one channel, and cross-channel switches are not intended. With cross-channel, individual channels are selectively linked – for example "buy online, pick up in store" (click & collect) or returning an online order at the store.
Omnichannel takes the final step: all channels are fully integrated, share a common data and stock foundation, and the customer experiences a seamless transition between them – from the shopping cart on the smartphone to advice in the store. The customer is at the center, not the individual channel. Multichannel is therefore the preliminary stage: it creates reach across many channels without necessarily merging them into a single experience. For many retailers, a cleanly set-up multichannel with central stock control is the pragmatic and economically sensible entry point before they evolve toward fully integrated omnichannel.
Example
Example: A mid-sized company expands from shop to multichannel
A manufacturer of outdoor equipment initially sold exclusively through its own online shop. To grow, the company gradually opened up further channels: an Amazon marketplace for reach, an eBay shop for remaining stock and a small retail store at the company headquarters for local customers. At first the team maintained stock and prices in each channel by hand – with the result that popular items were sold multiple times even though only one unit was in stock. Cancellations piled up and the marketplace reviews suffered.
As a solution, the retailer introduced an ERP system as a central hub. The item master and stock now sit centrally in one place, a PIM supplies all channels with unified product data, and connectors link the shop, Amazon and eBay. When one channel sells, stock drops immediately across all the others. For the retail store the system holds back a fixed buffer. The result: no more overselling, considerably less manual effort and an assortment that can be rolled out to further marketplaces without additional staff.
