Quick books has been very slow in loading for the last couple of days. Invoicing is taking me twice as long as usual. Anyone having the same problem or any suggestions/

Let's make sure to fix your QuickBooks loading issue, DJI.

QuickBooks Online (QBO) is a web-based service that relies on your computer or device processing power, the amount of available memory (RAM), and the bandwidth of your internet connection to perform as intended.

You'll want to ensure your system meets the basic requirements to help narrow down the reason for slow performance. Ensure your operating system is up to date for faster and smoother operation of your device and applications, new features and functions that enhance your user experience and productivity, improved protection from malware, viruses, and hackers, more compatibility with other devices and software, and bug fixes.

Aside from that, may I know what browser you are using? Intuit recommends Chrome to get the best experience. If you're using Chrome ensure to use the latest release by going to the Chrome menu and selecting Help, then About Google Chrome.

Also, verify your internet speed is not limiting your QBO experience. Run a Google Speed Test to confirm your bandwidth and the speed of your connection. To better understand the results of the Google Speed Test, read over how the results are determined and what they mean.

However, if the same thing happens, use an incognito mode. This mode can slow down performance for QuickBooks Online as each new session visit to the site causes all site elements to be fetched again. Subsequent page loads in the same session should be faster but the initial page loads will be slower.
