For a store full of one-of-a-kind used items, overselling is the biggest risk of selling online. When the only copy sells at the counter, it has to come off your website and marketplace listings right away. Here’s how to set up your channels so that happens automatically.
Keep one inventory, not three
Separate spreadsheets for your store, website, and eBay listings drift apart within days. Run every channel from one inventory in your POS so a sale anywhere updates stock everywhere.
Connect your online store
Link your Shopify store and marketplace accounts to your POS, then check that quantities match before you turn on syncing. GameSnapPOS keeps inventory in sync between your counter, Shopify, and online marketplaces.
List trade-ins the same day
Fresh trade-ins sell fastest. When a trade is accepted, the item should get a SKU and be ready to list online right away, with the condition and photos recorded at the counter.
Decide what stays in store
Some items are better sold in person, like high-value grails that customers want to inspect or bulky consoles that are costly to ship. Keep a clear rule for what gets listed online.
