The document discusses when businesses should upgrade their systems to enterprise resource planning (ERP) software and the benefits of cloud-based ERP software over on-premise ERP. Specifically, it recommends upgrading to ERP when a business has offices, warehouses, factories, or sales points across multiple locations or branches to help integrate operations and share information. It also introduces cloud ERP software, which stores data on remote servers rather than local hardware, allowing access from any internet-connected device.
