# Purchase order configuration

# Purchase order configuration

There are multiple ways you can customize your purchase orders. In this article, we will cover the main setup and configuration options.

## Add your company logo
You can upload your company logo under Settings --> Company

## **Add default terms & conditions**
**I**f your company has default terms & conditions that should be included on every purchase order, you can include this under Settings --> Purchase order setup --> Message to supplier. 
Here you can also select a file that will follow every purchase order.

In this section, you can also set up a default message to the supplier for emails that are sent from CostTracker to the supplier so that the user doesn't have to do this for each purchase.

## Add project number 
Some project-based companies want the project number to be included on the purchase orders. This is a separate field that can be activated under Settings --> Purchase order setup --> Project list (in the top right corner)

This is how the project number will appear on the PO (in the top right section).
