Hello - I use QB ONLY for invoicing and would like to enter my jobs as they are completed to streamline - they are flat rate - not hourly - how do I enter those?

Welcome to the QuickBooks Community, @nikkiboulay-cox-.

You can create an expense or check to your Job/Project's transaction to enter the flat rate. Let me guide you through the steps.

1. In your QuickBooks Online account, click the + New button and select Expense or Check.
2. Select the Job/Project from the Payee drop-down.
3. Fill out the necessary information.
4. Click Save and close.

However, if you're using timesheet for your jobs, there isn't an option to enter a flat rate. You might want to check this article to learn more about the Project feature in QuickBooks Online: Projects FAQ.

Please let me know if you need clarification about this, or there's anything else I can do for you. I'll be standing by for your response. Have a great day.

He means for invoicing customers not for paying suppliers. I need to know the same information. How do I go in and calculate sales taxes on the back end without my customers seeing it because we are flat rate. 

Thanks for joining this thread, dodsonplumbing.

Allow me to provide some information on how the Automated Sales Tax feature works in QuickBooks Online (QBO).

The Tax section on the invoice is built-in and designed for the customers to see the sales tax amount. That’s why the functionality to hide it on the sales form is unavailable.

If you’re unable to set up the flat rate in QBO, let’s go to the Sales Tax Settings section to add it. Let me show you the steps to get there.

Here’s how:

1. In your company, tap the Taxes menu on the left panel to select Sales tax.
2. In the Sales Tax Center, click the Sales tax settings link to open the Edit settings page.
3. From there, click the Add rate button to open the Add a custom sales tax rate window.
4. Select Single or Combined.
5. Fill in the field boxes with the right information.
6. Once done, press the Save button.

When you create an invoice, you can now use the newly created custom rate. For detailed instructions on how to add this to the transaction, check this article: Use custom rates to manually calculate taxes on invoices or receipts. Then proceed to How to use custom tax rates when you make a sale section.
