Word, Excel, PowerPoint, Outlook, Access, Publisher, and OneNote — the complete Professional Plus suite.

One-time purchase. You pay once — no monthly or annual fees. This is NOT Microsoft 365.

An Online Key is activated by entering a 25-digit product key directly into Office. A Bind Key links to your Microsoft account for easier reinstallation. Both give you the same software.

Send our support team your order number and a screenshot of the activation error. Most problems are an edition mismatch or a typo, and we'll help you fix it. If the key really is faulty, we send a free replacement within 24 hours — or a full refund if we can't replace it.
