I can see how having access to your Vendor search field could help you really streamline your day-to-day tasks, so I'm determined to help you restore it. The missing feature may be due to outdated cache files stored in your web browser. QuickBooks Online collects these files so you don't have to load repetitive text and images every time a page is loaded, greatly increasing the software's performance.
These files can often become corrupted or outdated, which may be leading to the missing search field. Clearing these temporary files is a breeze, just follow the steps at the links below corresponding to the browser you use:
Once you've cleared these files, close and reopen your browser, sign in to QuickBooks, and try accessing the vendor search bar again. We also offer an extensive guide on QBO's search functions that you may find helpful. Please keep me posted on whether or not this helps to resolve the issue. Thanks for coming to the Community, I look forward to hearing from you.
