Stop paying for SaaS

SaaS stack vs SharePoint SPFx
A fair look at where each approach wins. We have left in the one area where mature SaaS still leads.
| Capability | Typical SaaS stack | SharePoint SPFx by MStack360 |
|---|---|---|
| Monthly cost | $50 to $300 per user spread across many separate subscriptions | Already covered by the Microsoft 365 license you pay for today |
| Data residency | Vendor controlled, multi tenant, region depends on the SaaS provider | Your tenant, your region, your retention and DLP rules |
| Identity and access | Separate logins per tool, password sprawl, optional SSO add ons | Single sign on through Microsoft Entra ID, MFA and conditional access included |
| Microsoft 365 integration | Connectors and webhooks, often as paid extras | Native to Outlook, Teams, Excel, Power Automate, and SharePoint search |
| AI assistance | One assistant per vendor, each with its own data scope | Copilot for Microsoft 365 reaches across every app you replace |
| Customization | Limited to the vendor settings and roadmap | Fully tailored to your process, owned and extensible by your team |
| Compliance posture | Depends on each vendor SOC, ISO, and HIPAA stance | Inherits Microsoft 365 compliance, GDPR, HIPAA, ISO 27001 where licensed |
| Vendor lock in | High, exporting data and rebuilding integrations is painful | Low, data stays in SharePoint and Dataverse where you can reach it |
| Day one maturity | Polished feature set the day you sign up | Built to your spec, typical SPFx web part ships in 2 to 6 weeks Honest note: mature SaaS still wins on instant feature breadth. |
Six reasons SharePoint SPFx beats SaaS sprawl.
Beyond the cost savings, here is what changes when your apps live inside Microsoft 365.
Already paid for
Runs on Microsoft 365 licenses you already own. No new per user fees, no surprise renewals.
One identity, one security
Native Entra ID single sign on, conditional access, MFA, DLP, and Purview compliance from day one.
Data stays in your tenant
No third party servers, no data residency surprises. Everything lives in your SharePoint and Dataverse.
Branded for you
Your colors, your logo, your terminology. Not a generic SaaS dashboard.
Native M365 integration
Talks to Teams, Outlook, OneDrive, Planner, Power BI, and Copilot without custom connectors.
Scales with you
Add features, lists, workflows, and AI agents over time without changing platforms.
Honest considerations to share with clients
- Initial build cost is real. Custom SPFx work is an investment that pays back over 12 to 24 months.
- Not every SaaS fits. Highly specialized tools like advanced sales engagement, complex BI, or regulated platforms often stay on the SaaS.
- Maintenance shifts to your team or partner. SaaS includes the vendor's roadmap. Custom solutions need an owner.
- Best fit: companies with 10 to 250 users, multiple overlapping SaaS tools, and a mature Microsoft 365 footprint.
