An Overview of Inventory Source
Inventory Source is dropshipping automation software with an integrated supplier network of over 180 pre-integrated suppliers. With Inventory Source, you can automatically upload products, sync your inventory, and route orders with dropship suppliers to your online store or marketplace platforms.
However, there are several limitations to using Inventory Source as your dropshipping automation solution, including:
- Limited vendors: Inventory Source only works with their predefined list of vendors rather than allowing you to work with any vendors you like.
- Only one vendor per product listing: The solution links products to one vendor rather than allowing you to link one product to multiple vendors. This means you must have a product listing for each vendor.
- Pricing: Vendor markups will not change automatically if products are out of stock. This can impact your profit margins.
- Inventory: Your inventory is based on one product per vendor rather than having multiple products with various vendors.
- Order routing: This solution doesn’t allow for intelligent order routing, meaning orders aren’t automatically sent to, for example, the cheapest in stock vendor after they are placed in your online store.
- Electronic data exchange (EDI): EDI integrations are not available with Inventory Source, and orders aren’t automatically sent to vendors in the format they require.
- Fitment support: Inventory Source doesn’t offer fitment support, so you may experience catalog and inventory errors, and customers can’t search for auto parts by year, make, and model.
