[Billing](https://info.certificateofservice.com/knowledge/account-setup?hsLang=en#billing) # Understand your invoice ## Your invoice reflects the actual costs of processing and mailing your project. Each invoice is broken down into the following charges. **Printing** Printing is billed on the number of pages uploaded, multiplied by the number of recipients. For example, a 2-page document sent to 10 recipients results in 20 billable pages. **Postage** Postage is billed at the current USPS rate based on the weight of the envelope. This cost may vary by job depending on document length and the number of enclosures. We offer a postage discount via our Postal Acknowledgment Form.

As of the writing of this article, the fee is $.10 per page and is capped at $3.00 per job. This is a pass-through cost from PACER. **Payment Processing** - **Credit card:** A 3% convenience fee applies to payments made by credit card. - **ACH:** There is no processing fee for payments made by ACH. **Total Charges** Your invoice will show each of these charges broken out individually, along with the total amount due.
