What we need from you

• Your order information so we can match the delivery to the correct purchase
• The email address or contact method used for delivery, if required by the checkout process

• The Windows PC details if you are unsure whether your device is ready for activation

Delivery & turnaround

Delivery is typically completed within 1 to 48 hours after the order is received. In many cases, it is processed much sooner, but timing can vary depending on order volume, verification checks, and communication speed. If additional information is needed from you, the delivery may take longer.

Because this is an online service, the key is sent digitally rather than by post. Please make sure your contact details are accurate and that you can receive messages during the processing period.

Frequently asked questions

Is this a physical product?

No. This is a digital service. You receive an online activation key and any necessary instructions by message or email, depending on how your order is handled.

Can I use the key on more than one PC?

No. This product is for one PC only. If you need activation for another device, a separate license is required for that machine.

Do I need to install Office before activation?

In most cases, yes. You should have Microsoft Office 2021 Professional Plus installed on the target PC before entering the key. If you are not sure whether your installation is ready, we can help you confirm the next step.

What if my PC already has another Office version installed?

That can affect activation or compatibility. If you already have a different Office edition on the device, you may need to remove it first or follow the correct installation process for Office 2021 Professional Plus.

What happens if delivery is delayed?

Most orders are completed within the stated time window, but delays can happen due to verification, high order volume, or missing order details. If that occurs, we will continue processing and keep you informed as needed.
