The number of records you can sync at one time can vary depending on the module and the type of integration (e.g., QuickBooks, Xero, etc.). However, there is no fixed limit in CORE. The sync process is designed to handle large volumes of data efficiently. For best results, you can sync data in batches if you are working with a large volume of records or apply filters for selective syncing. If you experience timeouts or delays, try syncing fewer items at a time or contact BQE Technical Support for assistance.
