Hi there, SuperStar777.

I'd be glad to lend a hand with setting up retention to add to an invoice.

I recommend first creating a retainage account. Here's how:

1. Click the Gear icon in the top right corner.

2. Select Chart of Accounts.

3. Choose the green New button.

4. Click the Account Type drop-down arrow, then choose Other Current Assets.

5. Select the Detail Type drop-down arrow, then choose Retainage.

6. Enter a desired name, then click Save and close.

Once the account is created, you can then make a Retainage item to be included on invoices:

1. Click the Gear icon, then Products and Services.

2. Choose New, then Service.

3. Enter a name.

4. Check the I sell this product/service to my customers box.

5. Select the Income account drop-down arrow, then choose the Retainage account you created.

6. Click Save and close.

That should do it. I recommend talking this over with your accountant to make sure this would work for you, considering each business setup is a bit different. I'll be here if you have any other questions.
