Common ERP integration problems include data inconsistency, system compatibility issues, and a lack of standardisation between platforms. Businesses often find it hard to sync real-time data across systems, especially when using old or custom-built software. If you don’t plan well, don’t know who owns the data, and don’t test thoroughly, you might end up with delays, errors and higher costs. There are also security and compliance problems when connecting multiple systems, so it is essential to have a well-defined integration strategy and the right technical expertise.
