Spindle is the background inventory sync engine built for vinyl sellers. It keeps your Discogs, Shopify, Square, WooCommerce, eBay and Amazon listings in lockstep so stock levels, prices and sale states stay accurate across every channel without manual updates. Instead of copying changes between platforms every time a record sells, Spindle watches your inventory and pushes updates automatically — meaning fewer oversells, fewer cancelled orders, and more time to run your store.

Vinyl Atlas was born from the same shop-floor experience: a map of the world's record stores built from years of digging, travel and community recommendations. It started as a way to help crate-diggers find the best shops wherever they landed, and it grew into the geographic spine that connects the whole Catalog Music platform. Today it powers local store discovery, the marketplace's "ships from" filtering, and the location data behind every seller's webstore. Spindle, the marketplace, the webstore builder and Vinyl Atlas all share the same catalogue and seller identity — so stock, listings, store pages and location-aware search stay linked without duplicating data or chasing multiple dashboards.
