Stitch Labs is a simple order and inventory management solution for tracking parts, purchase orders, vendors, and inventory. Stitch Labs is a good solution for small merchants who manufacture their own products and need to manage the retail and wholesale side of their business. To sell across multiple channels and expand to new storefronts, you’ll still need to go to each channel and create your marketplace listings yourself.

Sellbrite also manages inventory across sales channels, but is built around deep channel integrations and a simple listing process for expanding your business. Sellbrite has an interface that’s fast and easy to use and allows you to store rich product data in a single, unified catalog. Linking your listings in Sellbrite happens automatically whenever you import something new into the system, unlike in Stitch Labs, where you must manually link products together even if your SKUs match.
