A shop needs more than a brochure site.
WHAT MATTERS
Memory. Set memory_limit to at least 256M. WooCommerce with a page builder and a few extensions will use it. Entry processes and CPU. Every checkout runs uncached PHP, so a busy shop consumes far more than a static site. Disk space and inodes. Product images multiplied by generated sizes add up quickly. Reliable cron, since WooCommerce depends on scheduled actions.
STARTING OUT
A mid-tier shared plan handles a small shop comfortably. Do not over-buy before you have traffic.
WHEN TO MOVE UP
Consistent resource limit warnings after caching is correctly configured Checkout slowing at peak times Hundreds of orders a day Large product catalogues with heavy filtering
WHAT UPGRADING DOES NOT FIX
A shop that is slow because of unoptimised images, a heavy theme, or twenty extensions will be slow on any plan. Fix those first.
