Should you build or buy SaaS Workspace Administration (Microsoft 365 & Google Workspace)?
SaaS Workspace Administration software manages the operational and security configuration of Microsoft 365 and Google Workspace tenants: user provisioning, license assignment, security baseline enforcement, sharing and permission audits, and delegated administration. IT and security teams use it to keep large tenants consistent and auditable across two admin consoles without hand-running scripts for every change.
Buy the governance layer you actually lack and script the rest. Graph PowerShell, the Admin SDK, ScubaGear and Maester cover baselines and lifecycle automation in production today, and CIPP shows how far open source reaches, but request portals, recurring access reviews and audit-ready delegation are a product your team would have to own, and AvePoint or GAT+ cost less per user than that ownership at typical scale.
Build it, buy it, or bridge?
When building makes sense
Building SaaS Workspace Administration works for bounded jobs: baseline assessment, license reporting, drift detection, and bulk lifecycle operations against Microsoft 365 or Google Workspace. Graph PowerShell and Google's Admin SDK expose every operation a governance product wraps around them. Maester, an open source test-automation project built by a Microsoft Entra engineer together with security MVPs, turns Microsoft's own security guidance into runnable Pester tests, and it now protects more than 60,000 tenants. CISA published ScubaGear on the same pattern: it verifies that a tenant's configuration matches CISA's own SCuBA baselines, and any team can run it for free. A team with spare scripting capacity can cover this slice directly. What a script does not replace is the request portal a budget owner opens without filing a ticket, the recurring access recertification an auditor wants proof of, and the approval chain that ties a change to a name. Build the bounded automation; do not try to rebuild the workflow around it.
When buying makes sense
Buying earns its place because the governance layer costs little and covers exactly what scripts leave open. AvePoint and GAT+ charge a modest per-user fee for the workflow layer: a budget owner requesting access without a ticket, an approval chain that runs itself, and a recertification cycle an auditor can inspect without asking your team to reconstruct history from log files. CoreView and ShareGate add configuration backup and drift detection across a tenant for teams managing many sites at once. None of this is strategic work. It is IT hygiene performed the same way at every tenant, and a product that has already built the governance layer beats maintaining one yourself once you need more than baseline scripts.

Frequently asked
Can IT manage Microsoft 365 and Google Workspace without buying a governance platform?
Yes, for bounded jobs. Graph PowerShell and Google's Admin SDK expose the same operations vendors wrap, and open tools like Maester and CISA's ScubaGear run production baseline checks against real tenants today. What native tooling does not give you is a self-service request portal, recurring recertification, or an audit-ready delegation model.
When does buying workspace governance software make sense?
Once budget owners need to request access without filing a ticket, or an auditor wants proof that permissions get recertified on a schedule. AvePoint and GAT+ charge a small per-user fee for that workflow layer, and it usually costs less than building and staffing the equivalent internally.
When does scripting your own tenant administration make sense?
When the job is bounded: baseline assessment, drift detection, license reporting, or bulk provisioning. A team with spare scripting capacity can run these directly against Graph or the Admin SDK and skip the license for that slice, the way ScubaGear already does for CISA baselines.
What's the practical difference between CoreView, GAT+, and AvePoint?
CoreView and ShareGate focus on configuration backup, drift detection, and change management across a tenant. GAT+ built its reputation on Google Workspace reporting and delegation. AvePoint centers on lifecycle governance for Teams and SharePoint sites. Most buyers use a slice of any one platform's full bundle.
