How we build an ecommerce website and mobile app: the six phases, in order.
Most projects pick the platform first. The catalogue should decide it - how many products,
how they vary, how often prices change, who edits them.
01 Discovery - catalogue shape, payment rails, who buys and how
02 UX and UI - storefront, product page, checkout
03 Storefront - the stack that fits the catalogue, not our favourite one
04 Mobile app - one codebase, both stores, same backend as the web
05 Payments - gateway, tax, shipping, refunds
06 Launch and care - ship, watch, fix, keep improving
The one that costs people the most: building the app later as a separate project, then
finding the web and the app disagree about stock and prices.
