I’m launching an online business that revolves around live card breaks and sports memorabilia, and I need a full-featured e-commerce site that seamlessly connects to both my Whatnot and eBay seller accounts. The store will be the heart of the operation—handling inventory, live-break spots, and one-off memorabilia listings—so clean product pages, real-time stock updates, and automated order syncing across the two marketplaces are non-negotiable. Platform-wise, I’m flexible as long as the final build can push and pull listings, images, prices, and tracking data to Whatnot and eBay without manual overlap. If that steers us toward Shopify, WooCommerce, or a purpose-built solution that taps into each API, I’m open to your guidance—just demonstrate that the integration will stay reliable when inventory turns over quickly. Beyond the storefront, I want a marketing foundation put in place: basic SEO on every product page, a lightweight blog section for break recaps, and email capture tied to a welcome sequence so fans get alerted to upcoming streams. If you’re comfortable drafting an initial social ad or two, even better; I’ll supply creative assets of the cards and memorabilia you can work with. Key deliverables • Fully responsive e-commerce website with branded theme • Live, bidirectional integration with both Whatnot and eBay (listings, orders, inventory) • Payment gateway set-up, shipping rules, and tax configuration for U.S. buyers • On-page SEO and schema for each product • Email capture and automated welcome series (Klaviyo or similar) • Quick-start marketing guide covering social ads, basic analytics, and content calendar Once the site is live and the first few breaks run smoothly through the new system, I’ll consider the project complete and tip for any stretch advice that helps scale faster. If you have proven experience syncing multi-channel inventory—especially with fast-moving collectibles—let’s talk about timelines and get this store breaking cards right away.
