Ecommerce inventory — the model build-off

Best choice for the deepest ecommerce inventory build.

Best at

The most complete build here. It tracks stock six ways at once — what you hold, what is promised to orders, what is actually sellable, what is on order, what is in transit, and what sits with partners — with permissions enforced on the server and connections to sales channels that admit when they are not connected instead of pretending. The deepest evidence trail of the set, across two locations and two channels.

Watch for

Honestly not finished: the connections to outside sales channels are waiting on credentials rather than live.

Best when breadth across operational screens matters.

Best at

The widest set of screens here — thirteen of them covering stock, products, sales channels, orders, returns, purchasing, transfers, partners, content and finance, plus a mobile view that works offline — on a real database where changes either fully happen or not at all.

Watch for

It undersells itself. Its handover says permissions are not enforced, but the finance screens are in fact restricted to the owner in the server code — the paperwork is more pessimistic than the app.

Best for correctness-critical stock math.

Best at

The most trustworthy stock maths. If you promise more than you hold, it says so — the sellable figure goes negative instead of quietly showing zero — every reserve, ship and cancel is recorded as a movement that can be undone, and owner-only settings are enforced on the server.

Watch for

A security check was too strict once hosted, and it refused to let anyone sign in.Fixed since audit — the check was loosened correctly, and the live demo now signs in cleanly.

Best order-commitment flow among the focused builds.

The best order-commitment flow among the focused builds — reserve, ship and cancel, each showing you exactly what will change before you confirm it, with reasoned low-stock warnings and working exports.

Watch for

Its two roles were never actually tested: every visit signed you in as the owner, the second role could only be invited and never used, and it shared a business name with an already-published build.Fixed since audit — both roles now sign in with passwords and the restricted role is genuinely refused by the server rather than just having buttons hidden, and the app was renamed.

Strong presentation, but as delivered it had no backend — treat the audit score as the starting line.

Best at

The best-looking of the set — a dashboard across sales channels showing what you hold, what is promised and what is sellable, with stock-risk panels and a clean layout on a phone.

Watch for

As delivered it only existed in the browser: no server, nothing saved, no real sign-in. Refreshing the page wiped every change, and there was nothing for permissions to protect.Fixed since audit — rebuilt properly over four rounds — a real database, real sign-in, permissions enforced on the server, and sixty products loaded — so the live demo now performs in the low nineties.
