Turn your store into a predictable, profitable sales machine on marketplaces.

SellSync is not a self-serve tool you wire up alone. You sign up through the form on this site and our team reaches out to onboard you: we connect your marketplaces, configure your operation and get SyncOS running for your store. The setup is done with you, not dumped on you, so you do not spend nights wiring integrations or reading manuals. Because the team handles the technical side, the time to go live depends on your channels and catalog, not on your tech skill. You go from the form to an operating store with the team guiding each step, instead of buying software and hoping you figure it out alone.

No. SellSync is built so a seller runs the whole operation without writing code or understanding APIs. You command it in plain language through SyncChat, and the AI specialists execute: SyncCortex optimizes your listings, SyncVox answers your buyers, SyncLog handles shipping and SyncTax handles the fiscal side. The technical setup, connecting your marketplaces and configuring the rules, is done by our team during onboarding, not left on your plate. Day to day, you ask for what you want the way you would ask a person, and the team of agents does the work. If you run your store today on spreadsheets and marketplace dashboards, you can run it on SellSync with far less effort and zero engineering.

SellSync currently integrates with Amazon, eBay, Walmart, Etsy and TikTok Shop, and we add new channels regularly based on what our sellers ask for. Each integration is native and real-time: your listings, pricing, inventory and orders stay in sync across every channel from one platform, so a sale on one marketplace updates the others on the spot. You do not rebuild a listing per channel or reconcile stock by hand. When you sign up through the form, our team confirms which of your marketplaces to connect and sets them up during onboarding. Opening a new channel later stops being a project, because SellSync takes over the operation on it the same way it runs the ones you already sell on.

Yes. You can try SellSync, and getting started is free. Instead of a self-serve credit-card trial, you fill out the form on this site and our team gets in touch: we understand your operation, show you how SellSync would run it for your store, and send you the link to test it. That short conversation is where we map your marketplaces, your volume and your goals, so the test fits your real operation instead of a blank dashboard. We do it this way because SellSync takes over a real operation, not just a tool, so it is worth a real conversation first. Sign up through the form and the team reaches out to you, with no commitment to start.

Yes. Your data is yours, and SellSync treats it that way. Connections to your channels use the official authenticated marketplace APIs, your data is encrypted in transit and access is controlled. As a Brazilian company operating for sellers across Brazil and Latin America, we handle personal and order data under the LGPD, the Brazilian data protection law, and the equivalent local rules. SellSync uses your data to run your operation, not to resell it. If you ever leave, your store, your listings and your history stay yours. Security is not something bolted on at the end; it is how the platform connects to your channels and handles every order.

Support works on two levels. For your buyers, SyncVox answers their questions on every channel, 24 hours a day, in your store's own tone, so a customer never waits and your reputation stays protected. For you, the seller, our team is involved from onboarding onward: we set the operation up with you and stay reachable as you grow, so you are never alone with a help center. You command the day to day through SyncChat in plain language, and when something needs a human, the team is there. The whole point of SellSync is to replace the operational team you would otherwise have to hire, so support is the operation running for you, with people behind it.
