Direct answer
WooCommerce can be a good shop if you already run WordPress well and keep plugins few. Custom e-commerce is preferable when checkout, COD rules or catalogue behaviour would otherwise require a fragile plugin chain, or when you want a small, fast storefront without CMS overhead.
How it works
Count paid extensions, page speed after plugins, and who patches WordPress. Custom still needs patches — just of your application, not of an entire CMS ecosystem.
Key considerations
- Content marketing sites may still want WordPress; the shop can be separate.
- Do not claim custom is always faster; poor custom code is slow too.
Avid’s approach
Avid e-Commerce is a purpose-built store (checkout, pincode, WhatsApp OTP login, partial COD as implemented for merchants who need them).
