Enterprise software powers the operations of the world’s biggest companies and none more so than SAP’s ERP systems. Ninety-nine of the world’s 100 largest companies are SAP customers, and an estimated 77% of global transaction revenue touches an SAP system. This ubiquity has given SAP a central role in enterprise IT, but also a reputation for high costs.
Many IT leaders today are asking whether SAP’s licensing and maintenance fees have effectively become a hefty “enterprise tax” on doing business. Meanwhile, a new generation of low-code platforms, led by Microsoft Power Platform Services, promises to change the game, helping enterprises deliver business solutions faster and at lower cost.
This article examines the economics behind SAP’s licensing model and explores how Microsoft Power Platform is redefining the cost-to-value equation for modern enterprises.
The Cost of SAP: A Heavy Burden on Enterprises
For decades, SAP’s ERP software has stood for reliability, scale, and integration depth. But it has also stood for steep license costs and rising support fees.
Maintenance alone can consume around 20–22% of the license price every year. Over five years, most enterprises end up paying their full license fee just to stay supported.
This recurring expenditure has earned SAP’s support model the label “support tax”, a yearly obligation that rarely scales with innovation.
The Multiple Funnels of SAP’s “Enterprise Tax”
1. High Annual Maintenance
- SAP Enterprise Support averages 22% of the license value annually.
- Fees have continued to rise as SAP introduced yearly support price increases (up to 5%), citing inflation and operating cost.
- For large deployments, that easily translates to millions of dollars in recurring expenses just to maintain compliance.
2. Shelfware and Over-Licensing
- Many organizations discover unused or over-provisioned licenses.
- One global manufacturer found 300 of its 800 SAP users were classified as full “Professional” users when only self-service access was needed resulting in $500,000 saved upfront and $110,000 annually by downgrading licenses.
- Without regular audits, enterprises keep paying for maintenance on idle licenses.
3. Indirect Access Fees
- The most unpredictable cost comes from indirect access when third-party systems (like Salesforce or web portals) interact with SAP data.
- In the well-known Diageo case, SAP demanded an additional £54 million in fees after the company integrated Salesforce with SAP, despite having already paid £50–60 million in license costs.
- The case forced CIOs worldwide to rethink integration strategies and license compliance.
4. Complex, Rigid Contracts
- Traditional perpetual licenses tie users to named metrics and usage models, making adjustments cumbersome.
- Newer cloud contracts (such as RISE with SAP) bundle software and infrastructure into subscriptions but Gartner notes some renewals have seen 10%+ cost hikes when escalation caps were not pre-negotiated.
- Discounts on on-prem licenses are also shrinking as SAP pushes customers toward its cloud ecosystem.
Why CIOs Call It a Tax
The cumulative effect of maintenance fees, unused licenses, indirect access penalties, and inflexible contracts feels like a recurring levy on digital operations.
In industries such as manufacturing where every basis point of margin matters CIOs often see SAP costs as a dent on innovation budgets. A 2025 analysis reported that SAP’s pricing and maintenance policies will likely continue to increase annually, and many organizations have postponed moving to S/4HANA due to these economics.
Gartner estimates that by 2030, over 40% of SAP clients will still be running legacy ECC 6.0 systems, forcing SAP to revisit its support deadlines. In short, many enterprises are staying put not out of preference, but out of cost containment.
This is where the shift toward Microsoft Power Platform Services begins to make strategic sense.
The Economics Behind Microsoft Power Platform : Where the Money Starts Coming Back
The emergence of low-code development is reshaping enterprise IT. It allows organizations to build business applications and automations with minimal coding effort turning weeks of development into days.
According to analysts, 70–75% of all new enterprise apps will be built using low-code or no-code platforms by 2026, up from just 25% in 2020.
Microsoft leads this movement with the Power Platform ecosystem, which includes:
- Power Apps for rapid app creation,
- Power Automate for workflow and process automation,
- Power BI for data visualization, and
- Power Virtual Agents, Copilot, Syntex, and Fabric as extensions for automation, AI, and content intelligence.
Its adoption curve is staggering Microsoft reported 48 million monthly active users in 2024, up from 33 million the previous year. Ninety-five percent of Fortune 500 companies now use Power BI, supported by over 5.8 million developers and citizen creators worldwide.
Why Enterprises Are Choosing Microsoft Power Platform Services
Organizations are drawn to Microsoft Power Platform Services because they directly address the inefficiencies that traditional ERP extensions failed to solve.
Faster Time-to-Solution
Low-code development reduces application delivery time by up to 50–70%, according to Forrester and Gartner. Pre-built connectors and reusable templates mean teams can deploy working prototypes within days, not months.
Lower Software Licensing Costs
- A Power Apps per-user license ($20–$40/month) is exponentially cheaper than a full SAP professional license (often ~$3,000 per user).
- Enterprises can deploy lightweight Power Apps as front-ends to SAP systems, extending capabilities to more employees without expanding SAP license counts.
- By integrating expert UX design services, organizations can ensure these Power Apps deliver not only functional efficiency but also an intuitive, user-centered experience that enhances adoption and productivity.
- This approach is fully compliant under SAP’s Digital Access framework but still significantly more cost-efficient.
Demonstrable ROI
- Forrester’s Total Economic Impact study recorded an average 206% ROI within three years of adopting Power Apps, with payback in under six months.
- Savings arise from reduced development time, automation of manual work, and avoidance of redundant third-party tools.
Real-World Proof Points
- PwC built a cybersecurity compliance app in six weeks using Power Automate Consulting, achieving 85% lower cost and 30% time savings compared to traditional methods.
- Ernst & Young automated financial documentation through Power Platform, cutting processing time by 95% and reducing associated costs by 30%.
Legacy Reduction and IT Simplification
Enterprises often run dozens of small point solutions for workflows, reports, and forms each carrying its own maintenance bill. With Power Platform:
- Multiple applications can be consolidated under a single Microsoft ecosystem.
- Companies have retired $50k/year BI tools and per-user SaaS fees by recreating equivalent functions in Microsoft Power BI Development Services and Power Apps.
- The result: simplified IT landscapes and significant reductions in total cost of ownership (TCO).
The Human Element: Empowering Citizen Developers
Beyond the numbers lies a cultural shift. The Power Platform enables business users not just IT teams, to participate in solution creation.
- 86% of IT leaders say low-code improves insight accuracy because business experts are closer to the process.
- 84% of organizations have already adopted or plan to adopt low-code tools to relieve IT backlogs.
- With Microsoft Copilot Automation, even non-technical staff can use natural language prompts to create workflows and dashboards.
This movement bridges the long-standing gap between business users and developers, accelerating innovation across departments.
