Ive updated the settings on my invoices to remove the service date, but when i create a new invoice that field still shows, how long til this updates?

Hope you're doing good, @vixaguilera-gmai.

Let's make sure you can create a new invoice without the Service Date.

When you create a new sale transaction, you have to apply the appropriate template (the one that doesn't have a Service Date field). Make sure you select the correct template by clicking the Customise button. Please take a look at the sample screenshot below.

If the same thing happens, probably, this is a browser-related issue. You can follow the steps below:

Step 1: Use an incognito window:

 It's a way to check issues caused by a full cache.
 

Step 2: Delete cache and temporary internet files:

If it works, you can clear cache and temporary internet files to optimize the browser's performance. It will also help delete the information stored in the cache. Another way is to use compatible browsers with QuickBooks Online.
