Katana

Katana is a cloud manufacturing ERP from Tallinn, Estonia. It tracks inventory in real time across sales channels and locations, including serial, batch and expiry tracking. It also covers bills of materials and subassemblies, production and shop floor management, purchase orders, demand planning, and warehouse work such as barcode scanning, bin locations and stocktakes. Stock is valued at moving average cost, and Katana calculates cost of goods sold when a sales order is packed or delivered. It suits small and midsize discrete manufacturers and e-commerce brands that make their own products, especially those selling on Shopify, WooCommerce or Amazon. Katana does not include its own general ledger. Instead it syncs with QuickBooks Online or Xero, creating invoices from sales orders, turning purchase orders into bills, and optionally posting COGS and operation costs. Other integrations cover BigCommerce, eBay, HubSpot, Salesforce, Pipedrive, ShipStation, ShipBob, Shippo and Zapier, alongside an open API and an MCP server for AI assistants. The current pricing page shows a free plan with all features, unlimited users and locations, but a cap of 30 SKUs, and an Advantage plan quoted on a scoped annual contract. Advantage adds unlimited SKUs, assigned implementation and customer success managers, custom integrations and reports, and 24/7 priority support. Older published pricing, starting at 299 USD per month with paid add-ons, no longer appears on the vendor's site. The main limitation is that Katana is not a complete finance system. Buyers still need a separate accounting package, and reviewers say it falls short for large, complex or heavily regulated manufacturers.
