What you need to know
An online store is more than a product grid. Variants, checkout rules, payment providers, delivery, taxes, stock, customer accounts, and fulfillment add build and testing work.
How to apply it
List product types, payment and delivery needs, inventory tools, and launch essentials. Request separate estimates for setup, migration, and recurring platform fees.
Common mistake to avoid
Comparing quotes by product count ignores checkout, returns, stock updates, and integrations.
