Try to open new invoice and banner comes up unable to connect to our service try again later

Hello there, precisiontrim. I know how important it is to have a seamless process when creating invoices. 

Before anything else, please know that the error message "Unable to connect to our service. Please try again later" means there's a temporary problem with the connection between your device and the QuickBooks Online servers. This error can happen for various reasons, such as network connectivity problems, server maintenance, or issues with your internet service provider.

First, let's ensure you're connected to a strong connection. If the issue continues, let's open your QuickBooks account in a private window to rule out browser-related issues. Here are the keyboard shortcuts:

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

If you can create an invoice, return to your regular browser and clear your cache. Occasionally, the accumulated cache and cookies in the system can become outdated or corrupted, leading to unexpected behaviors. You can also switch to other installed supported browsers, which is a good alternative.

Once you successfully create an invoice and receive a payment from your customer, you can record it in QuickBooks to mark it as paid. 

You can always reach out by tapping the reply button below. I'd be available to assist if you need further help to access your invoices.
