My estimate aren’t working it keeps lagging going back and forth with out me being able to type or add any context to the page

Hi, cyamil505. I'm here to ensure you can work on your estimates in QuickBooks Online (QBO) successfully. 

When our browser becomes overloaded, it can cause lagging and formatting issues while working on your QBO company. This can be the reason why you're unable to process your estimates seamlessly. To address this, we can open your account in incognito mode to determine if this is a browser-caused issue.

This window won't save your browsing activity, cache and cookies, or site data. To use one, here are the keyboard shortcuts you can follow:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P
• Edge: Ctrl + Shift + N

Once there, open your account and create an estimate. If you're able to process this successfully using a private browser, please clear your browser's cache for a fresh start. Also, I suggest using an updated browser so you can utilize QBO to its full potential. 

Once your customer accepts your estimates, you can transform them into an invoice. You can read this article to learn how: Convert an estimate into an invoice in QuickBooks Online.

Feel free to get back to this post if you need further assistance with your estimates in QBO. I'll be sure to get back to you as soon as possible.
