An Australian retailer sold the same inventory through its own storefront and several marketplaces. Orders were handled by hand, tracking was retyped, and the last unit could sell twice. Across six years, Mark Philippe Mirasol built the connectors, live stock push and deployment spine the retailer still runs while replatforming around them.
Catch, Kogan and MyDeal had no ShipStation integration. Each marketplace order took its own manual route into fulfilment, and every tracking number had to be written back by hand.
Underneath that sat the larger exposure: the storefront and marketplaces all sold from one physical stock pool, but none had a live shared availability figure. Overselling depended only on timing.
Mark built one authenticated PHP connector per marketplace using ShipStation's custom-store contract. The export action returns open orders as ShipStation-formatted XML; the ship-notify action writes carrier and tracking data back and marks the marketplace order shipped.
SkuVault became the single stock master and pushed live quantities to Catch and Kogan, so a sale on one channel immediately changed availability on the others. He also generated Amazon bulk listings from product data and images.
The integration layer connects order intake, fulfilment, stock and the new storefront.
The custom code stayed small at the boundary: translate marketplace orders into ShipStation's contract, then translate shipment events back. Keeping the connector narrow is why the retailer could replace the storefront without replacing the integration spine.
Marketplace orders now arrive in one ShipStation queue, and tracking returns to each channel without manual re-entry.
The real-time stock push closed the obvious overselling window on the shared pool. Six years after the first connector, the ShipStation, SkuVault and storefront integrations remained the layer being wired into the next platform.
No unsupported revenue or conversion figure is claimed. The proof is operational continuity across three contracts and 951 hours and thirty minutes of tracked work.
