Purchase Power Transaction Fee
Purchase Power® is a line of credit extended to you from Pitney Bowes. You are charged a transaction fee for borrowing the money for postage, with the advantage of being billed for the amount instead of having to prepay your postage account. Pitney Bowes must pay back the United States Postal Service for every refill at the end of every business day. The transaction fee covers the cost of extending postage immediately.
For detailed information about Purchase Power, see Understanding Your Purchase Power Account
If you have prepaid funds available in a USPS or Reserve Account, in addition to available credit in Purchase Power, your funds will be drawn from their prepaid accounts first when you refill postage.
