This hub covers two things that are usually treated as separate departments and are almost always the same person's problem: how the storefront is built, and whether you can trust what it reports.
On architecture, the recurring question is headless, which gets discussed as a tier rather than a trade. Decoupling the storefront from the commerce backend gives you control over rendering, payload, and integration; it also gives you a frontend to maintain that a hosted theme was maintaining for you. Worth it for some catalogues, clearly not for others, and the guides here try to say which is which rather than recommending it generally.
On measurement, the problem most stores actually have is that the ad platform, the analytics tool, and the actual order count all disagree, and the gaps widened as browser tracking restrictions tightened. Server-side event forwarding is the usual response, and the guides cover what it involves and what it costs to set up. It is worth being clear that it changes how events are collected and attributed, which is not the same as changing how many orders happen.
The link between the two halves is that both are measurement problems before they are engineering problems. Use your own baseline; published conversion statistics were measured on someone else's traffic and cannot tell you what yours is doing.
PandaCodeGen builds from $1,500 at a fixed price agreed before work starts, has no minimum project size, and the source code, design files and production accounts are yours at the end.

Speed is the usual suspect because it is the easiest thing to have an opinion about. A diagnostic order that finds the funnel stage which actually changed, including the problems WooCommerce creates that no hosted platform does.
Understand headless commerce architecture, Shopify and Medusa options, performance evidence, cost, operating tradeoffs and when a custom storefront is justified.
Checked against each platform's own API documentation rather than its marketing. Shopify, WooCommerce and Wix genuinely support it, Webflow runs the idea in the opposite direction, and Squarespace does not mention headless once.
Join route-level field performance to your funnel, build bounded opportunity scenarios, test the least disruptive remedy and separate measured outcomes from assumptions.
Segment the Shopify funnel by route, device, traffic source, and field performance before attributing conversion changes to speed or choosing a rebuild.
Plan Meta Conversions API cost from events, systems, consent, matching, deduplication, QA and monitoring, with a carefully labelled Panda Patches screenshot.
Reconcile platform events with the system of record, diagnose browser and server coverage, and improve consented measurement without assuming attribution or performance lift.
A consent-aware method for reconciling orders and Meta events, debugging browser and server delivery, and preventing duplicate events.
