Professional Productivity Suite

The suite is suitable for business users, professionals and organisations that rely on locally installed Office applications and do not need the continuously updated feature set included with Microsoft 365 Apps.

Word, Excel and PowerPoint 2021

Word 2021 is designed for documents, reports, contracts, letters and other professional content. It includes familiar editing, formatting and review tools for everyday business work.

Excel 2021 supports spreadsheets, formulas, charts, financial calculations and data analysis. It can be used for budgets, reports, inventory tracking and other structured business information.

PowerPoint 2021 provides tools for creating presentations for meetings, training, education and sales or business communication.

Outlook, Access and Publisher

Outlook 2021 provides desktop email, calendar, contact and scheduling tools. Service connectivity depends on the email platform and Microsoft’s support requirements.

Access 2021 is included for Windows and can be used to create and manage relational databases for business records, inventory, contacts and other structured information.

Publisher 2021 is also included for Windows and provides desktop publishing tools for brochures, flyers, newsletters and other print-oriented documents.

One-Time Purchase vs Microsoft 365

Microsoft Office Professional Plus 2021 is a one-time-purchase Office edition and does not include the ongoing subscription benefits of Microsoft 365. It does not automatically receive the continuous stream of new features that Microsoft 365 Apps receives.

If you prefer a subscription with ongoing updates and cloud-connected services, see our Microsoft 365 Personal – 1 Year Subscription option.

Digital Delivery

This is a digital software product. After payment confirmation, product information and installation or activation guidance are delivered electronically. No physical disc or boxed product is shipped.

Install the correct Office edition on a compatible Windows PC and complete activation according to the supplied instructions. Activation and usage rights depend on the specific licence supplied and Microsoft’s applicable licence terms.

Before You Buy

Please confirm that Office Professional Plus 2021 matches your required applications, Windows environment and support needs. Because support ends on 13 October 2026, organisations that require ongoing Microsoft security updates should consider a newer supported Office release.
