Shoud I use a credit account with PPI (Printed Postage Impression)?
If you spend more than £5,000 a year on Royal Mail services, you qualify for a Royal Mail credit account. This is an ideal way to pay for many of our services. If you don’t have space for a franking machine, you can pre-print the envelopes or labels, and place your order via our Online Business Account (OBA) system. As an account customer, you also have the added benefit of our credit terms.Back to top
