What is the difference between multichannel and omnichannel?

Multichannel means selling in several places that operate separately. Omnichannel connects those channels so inventory, customers and pricing are unified across all of them.

Do I need omnichannel if I am mostly in-store?

Even a small online presence benefits from shared inventory and customer data. Omnichannel prevents overselling and gives you one view of every customer.

Store, website and pop-up connected in one system

The short answer

Omnichannel retail connects your physical store, website and pop-ups so inventory, customers and pricing are shared in one system. It enables buy-online-pickup-in-store, consistent stock, and a single customer view, without juggling disconnected tools.

What omnichannel really means

Omnichannel isn't just "having a website too." It means your channels share one source of truth: the same inventory, the same customer profiles, the same pricing and promotions. A sale online instantly reduces in-store stock, and a loyalty point earned in person counts online.

The experiences it unlocks

With unified systems you can offer buy-online-pickup-in-store, ship-from-store, easy cross-channel returns, and consistent promotions. These conveniences are now expected by shoppers and directly increase sales and loyalty.

One customer view

When in-store and online data merge, you finally see the whole customer, what they buy, how often and through which channel. That powers smarter marketing and a better loyalty program.

Making it work

The key is a POS and gateway that connect to your ecommerce platform. Armour Payments unifies in-person and online payments and connects to 100+ platforms. See integrations and retail POS.
