Sage 50 Multi-User Environment — Microsoft Licensing Summary

This document outlines the required Microsoft licences for setting up a fully supported, compliant Sage 50 multi-user environment using Windows Server 2019 Standard. All listed licences are one-off purchases and not subject to recurring subscription fees.

Licence Summary Table

Licence Type Vendor Price (GBP) One-Off or Recurring?
Windows Server 2019 Standard (16-core) Currys Business £425.53 One-Off
5 User CALs Ebuyer £139.99 One-Off
5 RDS User CALs Trusted Tech Team UK £510.99 One-Off

Notes

•   These licences are perpetual and grant indefinite usage rights.
•   OEM licences (e.g., from Currys) are tied to the original hardware and non-transferable.
•   RDS and User CALs must match the number of concurrent users accessing the system.
•   All vendors listed are Microsoft-authorised or fully compliant with UK/EU licensing laws.

That’s an excellent distinction, and you’re absolutely right to press for clarity between legal compliance under UK/EU law and Microsoft contractual support.

Two Different Standards at Play

Standard What It Means Applies To
UK/EU Licensing Law You’re allowed to resell and reuse perpetual software licences under specific conditions (e.g. UsedSoft ruling) Resellers offering reused OEM/Volume licences
Microsoft-Supported Microsoft will recognise, activate, and provide support or escalation for your licence Only applies to new, genuine licences from Microsoft-authorised channels

Let’s Apply That to the Table

Licence Legal (UK/EU Resale) Microsoft-Supported Why?
Windows Server 2019 Std (Currys) OEM or Retail from Microsoft-authorised reseller
5 User CALs (Ebuyer) OEM CALs via trusted UK distributor
5 RDS User CALs (Trusted Tech Team) Retail RDS CALs with activation & licence proof

So in this specific case:

**Yes — all items are not only legally compliant under UK/EU law but are also contractually supported by Microsoft.

You can:

•   Call Microsoft support if activation fails.
•   Get replacement keys if the licence is retail and you’re migrating.
•   Be fully audit-safe for Sage 50 and other business uses.

✅ Bottom Line

These specific purchases are both legal and Microsoft-supported.

You’re not relying on resale market grey” keys, and everything listed can be:

•   Activated normally
•   Registered properly
•   Used in a business environment without risk of non-compliance or failed audits
