QuickBooks is that slow that it cant calculate my saved pay run and i cant send to tax department

Hi sjo12997,

I appreciate your time for trying out other options in resolving the performance in your QuickBooks Online account. 

We are committed to maintaining QBO's waiting time at 10 seconds and continuously monitor our systems to ensure we achieve this target. However, it's important to consider that the web-based nature of the program means its performance is also affected by your computer or device's processing power, available memory (RAM), and the bandwidth of your Internet connection.

I recommend checking this link Why is my QuickBooks Online slow? and verify if your browser and system requirements meets QBO guidelines.

Also, let's try to clear cache on your browser to remove saved cache and refresh the browser settings.

If the above has been verified and the issue persists, I recommend contacting our Customer Care Team. That way, they can check your account in a secure form.

Post again in the Community if you have other QBO concerns.
