Link invoice to a subcontractor

It's nice to have you in the Community, @kateacc. I'm happy to show you how you can link an invoice to a subcontractor. 

First, turn on the billable expense tracking. 

Here’s how: 

1. Go to Settings ⚙, then select Account and Settings.
2. Go to the Expenses tab.
3. From the Bills and expenses section, select Edit ✎.
4. Turn on the following:

• Show Items table on expense and purchase forms
• Track expenses and items by customer.
• Make expenses and items billable.

1. Enter Default bill payment terms.
2. Select Save.

From there, you can now enter a bill to a customer for an expense.

Here’s how: 

1. Select + New.
2. Select the transaction (Bill, Expense, or Check) you want to create.
3. Select the payee.
4. In the Category column, select the expense account for transaction.
5. Enter the description and amount of the expense, then select the Billable checkbox.
6. In the Customer column, select the customer you want to bill for this expense.
7. (Optional) Enter or make sure the markup % is correct, then select the Tax checkbox or choose a tax agency if you want to charge tax.
8. Select Save and close.

Also, please know that this feature is exclusive in QBO Plus and Advanced versions.
