That 8-second delay when adding a sub-customer to a parent account with many existing sub-customers is a known performance limitation in QuickBooks Online (QBO) due to the large list size, @virna1.
QBO must load and render the entire list to preserve the correct hierarchy and enable selecting the bill with the parent feature, which inherently slows the process.
While there isn’t a single setting to eliminate this delay, there are effective workarounds and best practices to speed things up:
- Ensure you have a stable internet connection. QBO is web-based, and performance depends on your computer’s processing power, available RAM, and bandwidth. A shortfall in any area can impact speed.
- Avoid having multiple browser tabs or apps open while using QBO, as this can consume resources and slow performance.
