Market Monster is inventory and profit software for online and retail arbitrage resellers who sell on Amazon, Walmart and eBay. It keeps inventory by location and works out true profit per item after marketplace fees, shipping and storage. It is in early access: accounts, teams and roles work today, and the reseller features are being built.
Every unit, where it actually sits.
One count per location instead of a spreadsheet per location: the Amazon FBA warehouse, the prep center, the storage unit and the garage. Each unit carries its own landed cost into the receipt.
Two things work today.
You can create a workspace, invite your team and assign roles now. Every reseller feature says In Development until it works in production.
