Welcome to SECND

What SECND does, who it's for, and the three things to know before you start.

TL;DR

SECND is one inventory system for everywhere you sell. Connect your marketplaces and POS, import your products, and SECND keeps quantities, prices, and listings in sync across every channel.

What SECND does

SECND connects your existing sales channels — eBay, Etsy, Shopify, Poshmark, Square, Lightspeed and others — into a single inventory and listing system. When you sell on one channel, the others update. When you list once in SECND, the listing appears on every channel you choose.

Beyond sync, SECND adds an AI assistant you can ask anything about your shop — what's in stock, what sold last week, what to price an item at — plus a weekly forecast that recommends what to restock.

Who SECND is for

SECND is built for independent resellers and brick-and-mortar shops that also sell online. You'll get the most value if you sell on two or more channels, or you run a physical store with a POS like Square or Lightspeed that you want kept in sync with your online listings.

Wait for the first import

SECND starts pulling your listings as soon as the connection completes. When the Products page shows your inventory, you're ready to cross-list or edit in bulk.
