The question asked, verbatim: best ecommerce platforms for retail shops

Brands named, in the order the engine gave

1. Shopify recommended
   Shopify - The default recommendation, and for most retail shops the right one.
2. Shopify POS mentioned
   Shopify POS syncs inventory, customers, and orders with the online store in one system, so a sale at the counter decrements the same stock as a web order.
3. Shopify Payments mentioned
   Downside: transaction fees if you don't use Shopify Payments, and app costs add up.
4. Square mentioned
   Square - Best if you're small, budget-conscious, or just getting started.
5. Online mentioned
   The POS is genuinely free, payments are built in, hardware is cheap, and Square Online gives you a serviceable storefront attached to the same catalog.
6. Lightspeed mentioned
   Lightspeed Retail - The pick for inventory-heavy specialty retail: bike shops, apparel, jewelry, liquor, anything with variants, serialized stock, or heavy purchasing.
7. Lightspeed Retail mentioned
   Lightspeed Retail - The pick for inventory-heavy specialty retail: bike shops, apparel, jewelry, liquor, anything with variants, serialized stock, or heavy purchasing.
8. BigCommerce mentioned
   BigCommerce - Worth a look if your catalog is large or structurally complicated (many variants, B2B pricing tiers, multi-currency).
9. WooCommerce mentioned
   WooCommerce - Only if you already run WordPress and want content/SEO and commerce on one site.
10. WordPress mentioned
    WooCommerce - Only if you already run WordPress and want content/SEO and commerce on one site.
11. Wix mentioned
    Wix - Fine for a small shop that's mostly a brochure site with a modest product list.

The answer, as recorded

For a retail shop - meaning you have a physical store *and* want to sell online - the thing that matters most is how well the platform unifies in-store POS with the web storefront. Here's who I'd actually name, in order: **1. Shopify** - The default recommendation, and for most retail shops the right one. Shopify POS syncs inventory, customers, and orders with the online store in one system, so a sale at the counter decrements the same stock as a web order. Massive app ecosystem (16,000+), easy themes, and it scales from one location to a hundred. Downside: transaction fees if you don't use Shopify Payments, and app costs add up. **2. Square** - Best if you're small, budget-conscious, or just getting started. The POS is genuinely free, payments are built in, hardware is cheap, and Square Online gives you a serviceable storefront attached to the same catalog. Setup is the fastest of anything here. The common complaint is that businesses outgrow it - reporting and inventory depth are thin once you're managing serious SKU counts. **3. Lightspeed Retail** - The pick for inventory-heavy specialty retail: bike shops, apparel, jewelry, liquor, anything with variants, serialized stock, or heavy purchasing. Real purchase ordering, supplier catalogs, multi-location stock transfers, and much stronger retail analytics than Shopify or Square. Costs more and takes more effort to run, so only worth it if inventory complexity is your actual pain. **4. BigCommerce** - Worth a look if your catalog is large or structurally complicated (many variants, B2B pricing tiers, multi-currency). It bundles features that are paid apps elsewhere, charges no platform transaction fees, and supports 65+ payment gateways. Weaker on the in-store side, so you'd be pairing it with a separate POS. **5. WooCommerce** - Only if you already run WordPress and want content/SEO and commerce on one site. Maximum control, no platform fees, but you own hosting, security, and updates. It's a real ongoing maintenance commitment, not a set-and-forget option. **6. Wix** - Fine for a small shop that's mostly a brochure site with a modest product list. Easiest builder of the bunch. I wouldn't build a serious retail operation on it. Short version: **Shopify unless you have a specific reason not to** - Square if you're tiny and want free, Lightspeed if inventory management is the real problem you're solving.
