A store is more than WordPress plus a shopping-cart plugin. Checkout, payments, shipping, taxes, email, subscriptions, caching, customer accounts and extensions all interact.
Changes around checkout deserve deliberate testing because failed payments affect revenue directly.
Custom pricing, product behavior and catalog requirements can become scoped development projects.
Third-party services and extension conflicts often sit inside the purchase workflow.
Account, membership and subscription behavior can be customized around your store model.
Payment gateways, CRMs, fulfillment systems and APIs may require custom development.
Store performance needs to be considered alongside caching, plugins and dynamic checkout behavior.
The Business care plan is designed for more important WordPress environments. Checkout customization, new integrations and larger WooCommerce changes remain project-based work so the scope stays clear.
