As the president of an IT consulting and cloud services firm, the most common cloud question I am asked is: “We want to move to the cloud – would you recommend Office 365 or G Suite?” Having observed a number of cloud migrations for small and mid-sized organizations, I believe there are a number of considerations necessary for selecting the appropriate cloud suite.

Both G Suite and Office 365 offer a comprehensive suite of collaboration capabilities with several important pros and cons. Looking at a company’s specific situation can help you determine which solution is better for an organization.

G Suite
Microsoft Office 365
Email, Contacts, Calendars, Tasks Pros: Simple, streamlined web experience.Cons: Creating well-formatted emails with pictures or attachments, or creating repeating calendar entries with invitations to external users. Pros: Single integrated app. More powerful software for complex email, contacts and calendar capabilities.
Google Drive OneDrive
File Sharing File storage and synchronization service that offers both online and offline access to files.Cons: It’s not as easy to save files to Google Drive from third-party cloud services. Shared file service.Pros: You can easily migrate thousands of folders to Office 365 while retaining existing Active Directory security group privileges.
Google Hangouts Skype for Business
Chat, Voice & Video Conferencing Chat, voice and video communications with seamless communications and strong user interface on mobile apps. Chat, voice and video conferencing with both internal and external contacts.Cons: Skype’s 2018 user interface overhaul is frustrating some users.

G Suite Office 365
Third-Party Add-Ons Google offers the ability to add third-party modules to G Suite, especially Gmail.

Most cloud services integrate with both G Suite and Office 365.

Microsoft’s Office 365 Store offers a wide range of third-party apps to enhance Office 365.

Most cloud services integrate with both Office 365 and G Suite.

There’s a much larger library of third-party modules, such as project management or purchase order approval, that you can incorporate into Office 365 and SharePoint.

User Acceptance, Ease of Migration

In general, Office 365 has a substantial edge over G Suite for most clients migrating from in-house Exchange and SharePoint environments. Users and IT staff are familiar with using and supporting the Microsoft Office suite and prefer staying with the same platform. Furthermore, Microsoft’s migration tools and processes have matured to enable seamless migration from Exchange servers to Office 365.

Marc Piparo, IT Director of Fortune Society, a 300-person nonprofit, moved from in-house Exchange servers to Office 365 email, calendars and SharePoint about two years ago. The organization’s primary motivation was improving reliability of email and communications during potential disasters. Piparo told Tom’s Hardware that he selected Office 365 in order to avoid retraining employees who are already familiar with Microsoft apps such as Word and Excel.

However, new organizations and clients migrating from non-Microsoft solutions are much more open to selecting G Suite. Brooks Ross, President of Leggiadro, a luxury women’s fashion retailer with 13 U.S. locations, migrated the company from an in-house Exchange server to Google G Suite two years ago because they wanted reliable communications without the cost of maintaining and operating in-house servers. He tells Tom’s Hardware Leggiadro chose G Suite because most store managers and staff need to work on iPads and wanted a simple, seamlessly integrated web-based solution.

Both Google and Microsoft offer built-in integrations to a variety of cloud services and extra features, including email archiving, CRM, marketing communications and more. Most cloud services today (CRM solutions, such as Salesforce, accounting/ERP solutions, like NetSuite, project management solutions, such as Slack) support integrations with both Office 365 and G Suite.

Piparo says Fortune Society was able to easily integrate their in-house CRM system to Office 365.  The nonprofit also integrates with AppRiver for email filtering and CloudAlly for third-party backup.

Ross tells us Leggiadro easily integrated their custom CRM app and email marketing solution with Gmail, as well as their client list.


In recent years, both G Suite and Office 365 have been reliable with minimal outages, and any outages I’ve seen have been fairly short (under an hour) and limited in scope (meaning only a few users or functions were affected).

Piparo attests to this, saying Fortune Society has had no outages in the two years they’ve been on Office 365. Meanwhile, Leggiadro has seen just one G Suite outage. According to Brooks, email was down for less than half-a-day, but the overall elimination of cost and hassles of in-house servers has been well worth it.

Security and Compliance

Both Microsoft and Google invest in security to protect their systems from hackers. However, they cannot protect you if your password is stolen. In addition to requiring staff to select strong passwords, IT can protect users by using built-in two-factor authentication capabilities. Google offers Google Authenticator, and Microsoft offers Microsoft 2FA.

Piparo says that because Fortune Society has access to personal and medical data, they enable compliance filtering on Office 365 and require staff to use encrypted emails when exchanging confidential personal data with partners or government agencies. They also improved security by greatly reducing the number of staff with remote access to the Fortune Society network since most information is now available on Office 365.

Google and Microsoft both have compliance options for monitoring the release of confidential data, also known as Personally Identifiable Information or PII, and also offer integrations with third-party archiving solutions.


Both Google and Microsoft offer an extensive online self-help knowledge base, along with telephone and chat help desk support. For the most common support issues, both companies offer suitable support services. For complex enterprise/integration issues, you may need to reach out to an experienced third-party IT provider for assistance.

Hardware Support

Google provides strong web-based functionality on Chromebooks and the Chrome browser on Windows and macOS. Its web-based functions on other browsers and other platforms, including tablets, are limited. You may also use the Google apps for iOS and Android, although they’re not as good as the Microsoft mobile apps for Outlook, Word and Excel.

Microsoft outshines Google in its support for complex spreadsheets and documents with its Office suite, which users can use on a Windows or macOS computer.


G Suite starts at $5/user/month for email, calendars, documents, spreadsheets, presentations, voice and video conferencing with 30GB storage/user. You can upgrade to G Suite Business for $10/user/month and gain unlimited storage, as well as email archiving. The most premium option is G Suite Enterprise, $25/user/month, which adds enterprise compliance and security alert capabilities.

Office 365 starts at $8/user/month for Office 365 E1, which includes web versions of its email, calendars, documents, spreadsheets, presentations, voice and video conferencing solutions with 50GB storage/user. You may upgrade to Office 365 E3, which adds the offline software suite (Word, Excel, Outlook, PowerPoint, Publisher and Access), as well as 100GB storage for $20/user/month, or Office 365 E5, which adds enterprise compliance and security alert capabilities for $35/user/month.

Bottom Line

If you’re moving a new organization over with connected mobile users mostly accessing productivity applications through web browsers, G Suite may be the right choice. G Suite offers a stronger web-based experience on Chrome browsers with seamless integration with its various components, with decent mobile apps. It’s also often preferred by smaller organizations for its simplicity and lower cost.

If you’re migrating an established organization with many users familiar with Microsoft Office’s more sophisticated capabilities, or have users who wish to work offline on their Windows or Mac laptops, Office 365 is a better fit.  Experienced Office users prefer the advanced software features of Microsoft Office software installed on their Windows or Mac, as well as the ability to more productive while disconnected. Office 365 has a good web-based experience, as well as high quality apps for iOS and Android.The Microsoft suite is usually preferred by larger organizations, because most IT departments are already accustomed to managing and supporting it.
