Frequently asked questions
Does SellSync keep my TikTok Shop catalog and stock in sync?
Yes. SyncCortex keeps your TikTok Shop catalog, pricing and stock synced across all your channels in real time, which matters most on TikTok Shop because a product can go viral overnight and sell out in hours. When a video drives a sudden surge, stock has to stay accurate to the second, or you oversell and rack up cancellations that hurt your shop rating and your reach in the feed. With SellSync, when an item sells on TikTok Shop, Amazon or eBay, stock drops everywhere at the same moment, so a spike on one channel never leaves you selling what you do not have. SyncCortex also keeps your pricing competitive inside the margin floor you set, so a trend converts into profit instead of a margin you regret.
Does SellSync handle TikTok Shop fulfillment when orders surge?
Yes. SyncLog handles TikTok Shop shipping end to end: labels, dispatch and tracking, from the order to delivery, and it is built to keep up when a viral moment sends orders through the roof. On TikTok Shop, shipping within the platform deadlines and adding tracking is what protects your shop rating and your eligibility for promotion, because late dispatch during a spike turns into cancellations and poor reviews fast. SyncLog watches every order and warns you before a deadline slips, even at high volume. It also keeps stock synced with your other marketplaces, so the same item sells on TikTok Shop, Amazon and eBay from one shared pool, with no overselling. You run the whole fulfillment flow from one place, without drowning in labels when demand hits.
How does SellSync handle sales tax on TikTok Shop?
TikTok Shop is a marketplace facilitator in the US, so it collects and remits sales tax on your orders for you in every state with a facilitator law, and you do not charge tax per order yourself. SyncTax handles what stays your responsibility: it reconciles the tax TikTok Shop 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 TikTok Shop. If you also sell direct through your own store, 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 gets harder as your volume grows.
Can I run TikTok Shop alongside other marketplaces?
Yes. SellSync runs TikTok Shop next to Amazon, eBay, Walmart, Etsy 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 a viral spike on TikTok Shop never leaves you overselling on another channel or taking cancellations that hurt your ratings. SyncCortex adjusts price per channel against each one competition, SyncLog handles fulfillment and deadlines even when orders surge, and SyncVox answers buyers in your store voice. 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.
