How to Add Postage to a Franking Machine: Top-Up Options Explained

You add postage to a franking machine by loading credit onto its meter, either directly on the machine or through your supplier's online account. The credit is then used up each time you print a frank, and you pay your franking provider for it, usually by Direct Debit, credit card or a credit account. The exact steps depend on your machine and supplier, but the process is broadly the same everywhere.

This guide explains how topping up works, what you need before you start, how to keep an eye on your balance and what happens to unused credit. It is written for UK mailrooms using a Royal Mail approved machine.

How postage credit works on a franking machine

A franking machine does not print postage for free. Instead, the meter inside holds a balance of prepaid postage, and every Mailmark frank deducts the correct amount. When the balance runs low you load more, and you settle up with your franking provider.

Royal Mail explains on its business franking page that you can pay for franking postage with Direct Debit, credit card and credit accounts with deferred payment terms. Which of those you are offered is down to your franking provider, so check your own agreement.

What you need before you top up

Before adding postage, make sure of two things:

• Funds are available. With Pitney Bowes, for example, you need funds in a PrePay account or be on a Pay As You Go arrangement.
• The meter can communicate. Modern machines connect to the supplier's data centre through a connection device, a PC link or a built-in connection, so the credit can be loaded securely.

If your machine will not connect, resolve that first. A weak or interrupted connection is the most common reason a top-up fails to appear.

Two ways to add postage

1. Top up on the machine

Most machines have a postage or funds option in the menu. You choose the amount, confirm it and wait for the meter to confirm the new balance. The screens differ between models, so follow your manufacturer's instructions for your machine. Supplier guides exist for popular ranges such as the Pitney Bowes DM110i and the Neopost IS290i.

2. Top up through your online account

Many suppliers let you add postage from a web account. As one example, Pitney Bowes explains that you sign in, choose Your Products and then Postage Meters, select Add Postage for the meter, enter the amount, choose Add To Meter and finally Confirm Refill. Wait for the confirmation message rather than closing the window early.

How to avoid running out at the wrong moment

A few simple habits keep your mailroom moving:

• Check your balance before the daily run. Mail that misses a collection because the meter was empty is an avoidable delay.
• Top up in sensible amounts. Base it on your typical weekly spend rather than a guess.
• Plan for busy periods. Our Christmas mailroom checklist covers what to prepare before the seasonal peak.
• Keep ink in stock too. A full meter is no use with an empty cartridge, so keep a spare from our best selling franking ink cartridges.

Get the amount right on each frank

Topping up only helps if each item is franked correctly. Choosing the wrong format wastes credit, so it is worth reading our guide to Letter, Large Letter or Parcel before you post. If you do over or under frank, see how to fix it before posting. For current prices, check our October 2026 postage rates update.

Remember too that Royal Mail says franked mail can be posted up to 7 days after the day the impression was printed, and that you must separate mail by destination, product and class to qualify for savings and avoid penalties. Our article on dating franked mail correctly explains the date side in more detail.

What happens to unused credit?

If you replace or cancel a machine, any credit left on the old meter should not simply vanish, but the process varies between suppliers. Pitney Bowes states that unused postage from an old meter is transferred to your Pay As You Go or PrePay account within 5 to 10 working days of the meter being returned, or immediately if you withdraw the meter yourself before returning it. Other suppliers have their own terms, so read your contract or ask your provider before you return a machine.
