I've registered my customer and the services I am providing. But when I make an invoice or sales receipt, it wont show up. What should I do?

Welcome to the Community.

I'll help you resolve issues you encountered when creating an invoice or sales receipt.

The stored files in your browser are typically the source of unexpected behavior or failures in QBO. Your cache saves the files from many websites you visit, so you can quickly load the pages the following time. The browsing speed of websites like QBO may be impacted if the cache is retaining too much data.

It's a good idea to check for issues brought on by a full cache when browsing anonymously because doing so prevents the cache from recording your browsing data.

• Chrome: Press Ctrl + Shift + N
• Internet Explorer and Mozilla Firefox: Press Ctrl + Shift + P
• Safari: Press Command + Shift + N

If the steps above will not work, you can use supported browsers as an alternative.

If the given procedures are successful, I advise you to clear the cache in your browser to avoid utilizing outdated forms, safeguard your data, and improve the performance of our programs on your computer.
