Overview
MNTN offers flexible billing methods to suit your business needs. This article explains how billing cycles work, the available payment methods, and how to apply for invoice billing.
Billing Cycle
Each month, your bill will be delivered to the email address you have provided in your account profile. Every bill will include the amount charged for the previous month's ad buying, the date it was generated, the card used, and a reference number.
Payment Methods
MNTN offers two billing methods:
Credit Card: Monthly automatic credit card payments made with the card on file.
Invoice: Monthly invoices generated and sent on Net 30 terms, which can be paid by ACH, wire transfer, check, or credit card (requires credit card authorization form).
All customers start with credit card billing. Select customers can switch to invoice billing.
Credit Card Billing
We run credit card billing typically by the 10th of the following month. The main email contact on your account will receive a credit card receipt. If you wish to change this contact, please submit a request to our Platform Experience Team by selecting the "Support" icon from within the Platform.
If you ever want to confirm that you are opted into Credit Card billing, you can look in the Billing Info section of the platform. There you will see the credit card information displayed. This can be done by navigating to the drop-down next to your account name in the upper right > Billing > Billing info.
When there is an issue with the credit card on file, you will receive an automated email from [email protected] with the subject line "Advertiser Payment Unsuccessful" to the main email contact on your account, asking you to update your credit card information in the MNTN platform. This can be done by navigating to the drop-down next to your account name in the upper right > Billing > Card.
Once you update the credit card on file within the platform, the payment will be re-run automatically. If you wish for MNTN to re-try the same credit card, you must submit a request to our Platform Experience Team using the steps described. If we are unable to process a successful payment by three business days after the first failed transaction, your campaigns will be paused automatically.
Once a bill has been successfully paid, it can be viewed in your account by selecting the drop-down next to your account name in the upper right > Billing > Billing History.
Invoice Billing
We invoice monthly on Net 30 terms, with invoices sent to anyone listed as an invoice contact in our system, typically by the 10th of the following month. Once an invoice has been sent out via email, it can also be viewed in your account by selecting the drop-down next to your account name in the upper right > Billing > Billing History.
Should you need MNTN's payment remittance information or ACH payment details, you can reach out to a member of the MNTN support team.
View Your Billing History
Select Billing History from the drop-down menu on the nav bar. Here you can view a full list of previous invoices:
Invoice Status
Once you pay your invoice, the platform may still show "Overdue" — this status is only updated once a month, typically at the end of the month or beginning of the next month, depending on the day of the week the month ends.
📘 Example: If you pay your invoice on the 25th, it may continue to show "Overdue" until the platform refreshes between the 30th–3rd. At that point, the status will update to "Paid", or you’ll receive an email notification if the payment was missed.
📝 Note: Invoicing is billed as a total amount based on your total spend for that month. Individual campaigns are not itemized; instead, charges are aggregated into a single monthly invoice.
Month to Date Spend
To view your campaign's month to date spend in a visual graph you can access this by visiting the Performance Tab within your campaign. In this view you will be able to see your campaigns month to date spend.
Spend Per Day
Or if you are more interested in the specific spend per day and would like to view this on a table of data points, you are able to view this in the Reporting Dashboard and selecting the 'Detail' tab in the Table widget to view a day by day breakdown.

Washington State Sales Tax Requirements (Effective October 1, 2025)
Washington State Sales Tax Requirements (Effective October 1, 2025)
On May 20, 2025, Washington Senate Bill 5814 was signed, expanding existing Washington sales tax to include advertising services. The legislation specifically includes online advertising services as taxable retail sales and encompasses all aspects of online advertising production and placement services.
The legislation went into effect on October 1, 2025, which means customers with billing addresses in Washington will see sales tax included on their invoices for advertising spend with MNTN.
How Washington sales tax is calculated
Washington sales tax will be calculated on the final sale price of each individual product or service. The amount of tax collected depends on many factors, including, but not limited to, the type of product or service you purchase, and your location/addresses within Washington. The address associated with your billing
profile will be used to determine the tax location for applicable taxes. Once your bill is finalized, sales tax to be collected will be displayed as a line item on your invoice.
Washington sales tax exemptions
If you have a valid Washington tax exemption certificate that applies to your purchases of advertising services from MNTN, you can submit it to [email protected]. Example of valid exemption certificates for advertising services include:
Reseller certificates: you are an agency or reseller that purchases advertising services from MNTN for
the purpose of resale to advertisers.Multiple points of use (MPU): you use the advertising services you purchase from MNTN across
multiple jurisdictions.
Your exemption will remain active until the expiration of your tax exemption certificate. To retain your tax exemption, you must submit an updated exemption certificate before the expiration of the current certificate. Applicable expiration dates are noted in our records.
Quick Answers

What happens if I miss a payment?
For clients billed by credit card, we understand that if an updated payment is not received within 3 days of the initial decline, campaigns will be automatically paused. For clients billed by invoice, unpaid invoices after 90 days will have their campaigns paused.
Why is my campaign's spend slightly higher than my campaign's set budget?
Why is my campaign's spend slightly higher than my campaign's set budget?
Due to industry assumed discrepancies, we have designed our system to always continue to spend past the budget to win valuable inventory. This also helps ensure that we fulfill your campaign's maximum budget. MNTN will ONLY charge the amount budgeted for the given month and will absorb the cost of these discrepancies. Please be assured that we will never charge your credit card more than the budget inputted into your campaign's budget.
Why does my account still say overdue when I paid my invoice already?
Why does my account still say overdue when I paid my invoice already?
The invoice status in the platform will be adjusted by the end of the invoice due month/beginning of the following month. Therefore, if you pay your invoice on the 15th, it should reflect 'paid' in the platform by the 3rd of the next month at the very latest.
