How Redress Compliance helped a major Spanish retail group with 8,000 employees and €2.5 billion in revenue save €1M over three years by right-sizing Microsoft 365 licences, shifting 2,000 frontline workers from E3 to F3, eliminating 300 inactive accounts, negotiating a 10% annual flex clause, and simultaneously improving store-level productivity through better adoption of included Microsoft tools.

The client is a major Spanish retail group headquartered in Madrid, operating a chain of supermarkets and retail stores across Spain and Southern Europe, plus a growing online marketplace. With approximately 8,000 employees and €2.5 billion in annual revenue, the company operates in an industry defined by razor-thin margins where every cost line is scrutinised.
The IT function supports both a corporate headquarters workforce of approximately 1,500 knowledge workers and a distributed frontline workforce of over 6,000 store-based employees including cashiers, stock clerks, supervisors, and regional managers.
The existing Microsoft environment reflected a complex history of incremental licensing decisions rather than a deliberate strategy. Corporate office staff and store managers (approximately 2,000 users) were on Microsoft 365 E3 licences. The remaining frontline store employees were on a mixture of F3 and E1 licences, though many had been assigned E3 licences during earlier roll-outs because it was simpler than differentiating between role types.
The retailer had also acquired a smaller competitor the previous year, absorbing approximately 500 additional employees whose licences had been folded into the EA on an ad hoc basis. This acquisition compounded the licensing complexity: the new stores brought different usage patterns, many accounts were inactive or duplicated, and the integration had not included a systematic review of which Microsoft services the acquired workforce actually needed.
Frontline over-licensing. Over 600 store employees held E3 licences (€30+/user/month) but only used email and Teams occasionally on shared kiosks. These workers needed web-based access, not the full Office desktop suite. A classic case of enterprise-grade licences deployed to roles that require frontline-grade tools.
Ghost accounts. Approximately 300 inactive accounts, from employee turnover, the acquisition, and seasonal workers who had left, remained assigned to paid licences. Every ghost account was a pure waste line item, costing hundreds of thousands of euros annually for users who no longer existed.
Shelfware and low adoption. Features included in E3 (Yammer, SharePoint, advanced compliance tools) had negligible adoption in stores. Meanwhile, tools that could genuinely improve frontline operations, Teams Shifts for scheduling, SharePoint for training materials, were not deployed because the company had never enabled them.
EA rigidity for retail. Standard EA terms locked the company into fixed licence counts for three years. In retail, store counts change (openings, closures, seasonal peaks), staffing fluctuates by hundreds, and the acquired competitor's stores might be divested. The EA offered no mechanism to flex down without paying for licences no longer needed.
Microsoft's renewal proposal made things worse. The Microsoft account team proposed upgrading all E3 users to E5, citing advanced security and analytics capabilities, and adding more Power BI Pro licences. This would have increased the EA cost by approximately 30% while delivering features that the vast majority of the workforce neither needed nor would use. The proposal contained no analysis of actual usage patterns, no right-sizing recommendations, and no flexibility provisions for the retail operating model.
| Metric | Before Engagement | After Redress Advisory |
|---|---|---|
| Annual Microsoft EA cost | €1.67M/year (previous EA) | €1.33M/year (20% reduction) |
| 3-year savings | Microsoft proposed a 30% increase | €1M saved vs prior EA; €1.5M+ vs E5 upsell |
| Frontline licence tier | Mix of E3, E1, F3 (many over-licensed) | 2,000+ users standardised on F3 at ~1/3 of E3 cost |
| Inactive accounts | ~300 ghost accounts consuming paid licences | All identified and deprovisioned; licences reclaimed |
| Licence flexibility | Fixed counts; no ability to flex down | 10% annual flex on F3/F1; CSP for seasonal workers |
| Frontline tooling | Scheduling done manually; low digital engagement | Teams Shifts, SharePoint training hub, Walkie Talkie deployed |
| Strategic position | Microsoft dictating upsell roadmap | Client controls adoption timeline; E5 available as option, not obligation |
In a retail environment where net margins typically range between 2% and 4%, a €1 million cost avoidance is equivalent to the IT budget for several new store openings. Over 2,000 frontline employees shifted to F3 without any loss of productivity. Store managers retained full E3 capability. The 100 power users gained E5 features they genuinely needed. The result was zero waste: every licence tier matches the actual requirements and usage patterns of the role it serves.
"For the first time, our Microsoft licensing aligns perfectly with our business, and it is saving us a fortune. Redress Compliance revealed that we were overspending in areas that added no value, particularly in our stores. By right-sizing our licences, we reduced costs by approximately 20% (€1M) and enhanced collaboration among our staff using Microsoft 365. It is rare to save money and enhance productivity at the same time, but Redress made it possible. They truly acted in our best interest, pushing back on Microsoft's upsell and tailoring the agreement to fit our retail operations." IT Director, Spanish Retail Group
Microsoft 365 E3 is designed for knowledge workers and includes the full Office desktop suite (Word, Excel, PowerPoint, Outlook desktop), advanced security features, compliance tools, and 100 GB of OneDrive storage. Microsoft 365 F3 (Frontline) is designed for shift-based and frontline workers. It includes Outlook web and mobile, Teams (with Shifts, Walkie Talkie, and Tasks), SharePoint, and limited OneDrive storage, but excludes the Office desktop applications. F3 costs approximately one-third of E3. For employees who only access email through web or mobile and do not need desktop Office apps, F3 delivers all necessary capabilities at a fraction of the cost.
The 20% reduction (€1M over three years) came from three complementary actions: licence tier right-sizing (shifting 2,000+ frontline workers from E3 to F3, reducing per-user cost by approximately 65%), ghost account elimination (deprovisioning 300 inactive accounts that were consuming paid licences), and negotiation leverage (using detailed usage analytics to reject Microsoft's blanket E5 upsell, secure volume discounts on F3, and negotiate a retail sector incentive).
A flex clause allows the customer to increase or decrease a specified percentage of licences at each annual EA anniversary without penalty. Standard EA terms lock you into fixed counts for three years. In retail, staffing levels fluctuate due to store openings and closures, seasonal hiring, and M&A activity. The 10% annual flex clause Redress negotiated means this client can reduce up to 10% of its F3/F1 licences each year if its workforce shrinks, or add up to 10% if it grows, without renegotiating the agreement.
No. The 2,000+ workers moved from E3 to F3 experienced no loss of day-to-day functionality because they were already using only the capabilities included in F3: Outlook web and mobile for email, Teams for messaging and video, and SharePoint for accessing company information. Most workers did not notice the change. Several workers actually gained new functionality through the rollout of Teams Shifts and Walkie Talkie, which were included in F3 but had never been enabled.
Rather than including permanent annual licences in the EA for workers present only during the holiday period, Redress recommended procuring temporary F3 licences through a Cloud Solution Provider (CSP) on month-to-month terms. The retailer pays for approximately 200 seasonal licences for only the months they are needed (typically November and December), then cancels them in January. This ensures Microsoft spend correlates directly with actual workforce size.
Three frontline tools that were already included in F3 but never activated: Teams Shifts for scheduling and shift management, SharePoint training portals for centralised distribution of training materials and corporate announcements, and Teams Walkie Talkie for push-to-talk communication replacing physical walkie-talkies. These tools were deployed at zero additional licensing cost, improving frontline productivity while overall EA cost decreased.
E5 includes advanced security features that provide genuine value for security teams, IT administrators, and executives handling sensitive data. However, deploying E5 organisation-wide is rarely cost-justified. Most organisations find that fewer than 10% of users benefit from E5 security features. The recommended approach is to assign E5 selectively to the security team, IT administrators, and high-risk users, while keeping the broader workforce on E3 or F3. In this case, only approximately 100 users (out of 8,000) moved to E5.
