Does anyone knows how to deduct or insert 10% hold back in a partial INVOICE

Hi @barrosocristian- 

it is great that you have reached out to the community for assistance. Knowing where to navigate things around QBO is important for a business.

If you are looking to set up a discount on the invoice, please see below:

All you have to do is follow these steps:

1. Click the Gear icon.
2. Select Account and Settings.
3. Click Sales tab.
4. Click the pencil icon under Sales form content.
5. Put a mark into the box next to Discount.
6. Click Save and Done.

If you're using an invoice template, you can edit the template by following the steps below:

1. Click the Gear icon.
2. Select Custom Form Styles.
3. Select the invoice template, and click Edit.
4. Click the Content tab, and then click the pencil icon at the bottom of the invoice.
5. Put a check mark into the box next to Discount.
6. Click Done.

I hope this has answered your question, if not reach out back.
