SellersSense is built for sellers, not enterprises. The same tooling the big platforms charge $1k+/month for, priced for the people who actually run the warehouse — with a free tier for new sellers and repricing bundled into every paid plan instead of being a $300/month add-on.
Under the hood it's a multi-tenant .NET 10 SaaS: 13 modular subsystems (catalog, listing, order, repricing, automation, billing, shipping, marketing, analytics, notification, marketplace, admin, tenancy) running on the same Evolved Sense platform as the rest of the suite.
