Extensiv
Integration-focused order and inventory management for multi-channel sellers
About Extensiv
Extensiv (formerly Skubana and CartRover) offers a suite of e-commerce operations tools centered around its Integration Manager — a middleware platform that syncs orders, inventory, and shipment data between shopping carts, marketplaces, warehouses, and fulfillment providers. Unlike platforms that try to be the system of record, Extensiv specializes in connecting the tools sellers already use. The platform's Integration Manager handles unlimited order volume on all plans, passing data between order sources (Amazon, Shopify, eBay, Walmart) and order destinations (3PLs, warehouses, dropship vendors) in a standardized format. Its Order Management product (formerly Skubana) adds advanced inventory allocation, demand forecasting, automated purchasing, and profitability analytics for brands that need a central command center for their multi-channel operations.
Pros & Cons
Pros
- Unlimited order volume on all plans — no surprise charges when sales spike during peak seasons
- Integration Manager at $39/month is the most affordable entry point for connecting sales channels to fulfillment providers
- Specializes in connecting existing tools rather than replacing them — works alongside your current tech stack
- Custom field mapping ensures data integrity when syncing between platforms with different data structures
- Free trial with no credit card required lets sellers test integrations before committing
Cons
- Integration Manager is middleware, not a full inventory management system — sellers still need a separate platform for warehouse operations
- Order Management product pricing is custom/enterprise-only, making it inaccessible for smaller sellers
- Initial integration setup can be technical — connecting complex fulfillment workflows may require support help
- Fewer direct marketplace listing features compared to all-in-one platforms like Linnworks
