Overview
Billing Details is where you keep your payment information current and see what you've been charged. From one page, you can add or update a payment method, manage the address and contacts we use for invoicing, and review or download your billing history.
If a credit card payment has already failed, see Fix Credit Card Payment Issues.
📝 Note: Every month, we will send you a receipt referencing this information to the email address you provided at sign-up. Please note you can always change that email address.

From Billing Details, scroll down to the Billing History table.

Add Or Update A Purchase Order
Some organizations require a purchase order (PO) number to appear on their invoice before payment can be processed. PO numbers are added at the invoice level.
Before your invoice is generated, contact MNTN Support and provide:
Your Account ID (AID)
The PO number
The related campaign or billing details
⚠️ Warning: If a PO number isn't provided before the invoice is generated, your payment timeline may be affected.
After your invoice is issued:
From Billing Details, scroll down to the Billing History table.
Find the invoice you want to update.
In the PO Number column, click Add PO.
Enter the PO number and press enter.
Download the invoice again if you need an updated copy.
