A2000 is a warehouse management system (WMS) developed by GCS that provides inventory management, order processing, and fulfillment capabilities for e-commerce businesses. ## What Does the Integration Do? A2000 has built a native integration with Redo directly into the A2000 package. This integration is managed within A2000 itself. The integration connects Redo and A2000 through two key touchpoints: **RMA Import** When a customer initiates a return through Redo, the RMA (Return Merchandise Authorization) is automatically imported into A2000, notifying the warehouse that items are being returned. **RMA Receipt Export** When returned items are received and processed in your A2000 warehouse, A2000 exports the receipt confirmation back to Redo, which automatically triggers the appropriate return outcome—whether that's a refund, exchange, or store credit. This eliminates manual data entry between systems and keeps your warehouse team and customer service team in sync. ## How to Set It Up The Redo integration is built into the A2000 package and is available to customers on the current release. To enable the integration, contact A2000 support at [A2000support@gcsnet.com](mailto:A2000support@gcsnet.com). ## Support For issues with A2000 access, warehouse operations, or the Redo integration, contact your A2000 account manager or support team.
