Between the spreadsheet and enterprise software sits Inventoros, a self-hosted system for tracking stock, orders, and suppliers across warehouses. A replenishment panel on the dashboard flags products below their minimum, and purchase orders go to suppliers by email and are received into stock. Products carry SKUs, variants, kits, batches with expiry dates, and serial numbers, with barcodes and QR labels for products and locations. Warehouses nest aisles, shelves, and bins, stock moves between them, and staff can be limited to the sites they work in. Orders handle approvals, payments, refunds, PDF invoices, partial shipments, and returns, and a customer portal shows invited contacts their orders, shipments, and balances. Twelve built-in reports cover valuation, turnover, dead stock, profit margin, and ABC analysis, and a custom report builder exports to CSV, Excel, or PDF on a schedule. Webhooks, a REST API, GraphQL, signed plugins, and an MCP server connect it to the rest of your stack and to AI clients acting with a user's token. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
