## Frequently Asked Questions

**Is Inventory Manager really free?**

Yes! The extension is completely free to install and use. There are no hidden fees, no feature gates, and no registration required.

**Does it work offline?**

Yes! Because it relies on local-first data storage directly in your browser, you can access your product catalog and make adjustments even without an active internet connection.

**What types of businesses is this for?**

It is a universal system perfect for retail, wholesale, manufacturing, e-commerce, and 3PL businesses of any size.

**Can I track customers and suppliers?**

Absolutely. It includes comprehensive directories for both customers and suppliers, allowing you to link customer orders and manage complete purchase workflows with receiving.

**Do you support multiple warehouses?**

Yes, you can track inventory across unlimited warehouse locations, perform stock transfers, reservations, and adjustments seamlessly.

**Is my data safe and can I export it?**

Your data stays 100% private in your browser. You can export key data to CSV and XLSX formats at any time, and use the built-in backup and restore functionality to keep it secure.

**What languages are supported?**

The Inventory Manager interface is fully multilingual and currently supports English, Russian, and Spanish.

**Is there a mobile app?**

Yes! InventoryMod is available for Android on Google Play. It offers the same local-first inventory management as the Chrome extension, so you can count stock and update balances directly from your phone. You can use the extension and the app independently — each keeps its data on its own device.

**Can I use it online without installing anything?**

Yes. There is a web version you can open right in your browser — no installation and no sign-up required (sign-up is needed only for team work). It gives you the same inventory manager as the extension and the Android app, so you can start working instantly from any operating system.

**Can my whole team work in it?**

Yes, in the web version. The owner invites staff by email and assigns a role: manager, warehouse clerk, viewer, or a custom role with exactly the permissions you need. Access can be limited to specific warehouses and purchase prices can be hidden. If two people edit the same document, nobody's changes are silently overwritten.

**Does it support kits, assembly and manufacturing?**

Yes. Define a bill of materials for a product; assembly consumes the components and adds the finished product to stock at a cost rolled up from its components. A virtual kit is sold in orders — its components are reserved and shipped automatically. Assemblies and disassemblies can be undone as a whole.

**How do I manage products with sizes and colors?**

Create a model, add axes (e.g. Color and Size) and their values — variants for every combination are created with one button. Each variant has its own SKU, barcode, price and stock, and they are grouped under the model in the product list.
