Hi there, -g. Let me assist you in updating your invoices in QuickBooks Online (QBO).
We can modify invoices without contacting customer service. Since QuickBooks won't allow you to update your transaction, let's make sure to access your account as an admin to avoid restrictions.
Additionally, you can try performing the process through a private window to narrow down the result. This procedure can help eliminate any cache-related concerns that might be causing the behavior. You can save time by using one of the following keyboard shortcuts:
- Google Chrome: Press Ctrl+ Shift + N
- Safari: Press Command + Shift + N
- Mozilla Firefox: Press Ctrl+ Shift + P
If it works fine, switch to your default browser and clear the cache to refresh the system.
