Frequently asked questions
Does SellSync optimize my eBay listings and pricing?
Yes. SyncCortex keeps your eBay listings and prices sharp so you compete for Best Match placement without touching each listing by hand. On eBay, price, handling time and seller rating all feed the Best Match algorithm that decides who shows up first, and falling behind there quietly costs you views and sales. SyncCortex tracks the competition and adjusts your price inside the margin floor you set, so you compete for position without selling at a loss. It also keeps inventory synced across your channels in real time, so you never list what you cannot ship and never take a cancellation for being out of stock, which on eBay counts as a transaction defect against your account and pushes you down in search.
Does SellSync handle eBay shipping and handling time?
Yes. SyncLog manages eBay shipping end to end: labels, handling time, dispatch and tracking, from the order to delivery. On eBay, hitting your stated handling time and adding tracking is what protects your detailed seller ratings and your Top Rated Seller status, because a late or untracked shipment turns into a defect on your account. SyncLog watches every order and warns you before a deadline slips, so you keep your metrics clean. It also keeps stock synced with your other marketplaces, so the same item sells on eBay, Amazon and Walmart from one shared pool, with no overselling. You run the whole shipping flow from one place, without spreadsheets and without printing labels one at a time.
How does SellSync handle sales tax on eBay?
eBay is a marketplace facilitator, so it collects and remits sales tax on your marketplace orders for you in every US state with a facilitator law, and you do not charge tax per order yourself. SyncTax handles what remains your responsibility: it reconciles the tax eBay collected against your orders, tracks where your sales and inventory create nexus, and keeps your records ready for your filings. There is no per-order tax document for you to issue on eBay. If you also sell direct through your own site, SyncTax flags the states where you may need to register and collect on your own. The result is clean, audit-ready tax records across every channel, without the manual reconciliation that eats time as your order volume grows.
Can I run eBay alongside other marketplaces?
Yes. SellSync runs eBay next to Amazon, Walmart, Etsy, TikTok Shop and your other channels from one platform, with inventory and pricing synced in real time. When a product sells on one channel, stock drops everywhere at the same moment, so you never oversell or take a cancellation for a stockout, which on eBay counts as a defect against your account. SyncCortex adjusts price per channel against each one competition, SyncLog handles labels and handling time, and SyncVox answers buyers in your store voice to protect your seller rating. In practice, you operate several storefronts as if they were one, without multiplying the work each time you open a marketplace, and you add channels without hiring more people.
