Which SunSystems version are you running and is it still supported?
Having worked with SunSystems for nearly 30 years, we've seen the product evolve significantly. One of the most common questions we get asked is: "Which versions of SunSystems are still supported, and what are my upgrade options?"
If you're currently running an on-premise version of SunSystems, it's important to understand where your system sits in the product lifecycle and what that means for your business.
Which SunSystems versions are currently supported?
- SunSystems Cloud – Infor's fully managed Software-as-a-Service (SaaS) solution
- SunSystems 6.4 On-Premise – The latest supported on-premise release
There is also a SunSystems 6.4 Hybrid deployment. This combines a traditional on-premise SunSystems installation with selected cloud-based Infor services.
The hybrid approach was introduced following the retirement of several on-premise Infor technologies, including components such as Infor OS and ION. By moving these services into the cloud while keeping the core SunSystems application on-premise, organisations can benefit from much of the additional functionality available in the cloud without fully migrating their ERP system.
For many businesses, this provides around 80% of the additional capability while allowing them to continue running their existing on-premise environment.
What happened to the older versions?
Legacy versions, including SunSystems 6.3, 6.2 and 6.1, have now moved to Sustaining Maintenance under Infor's extended maintenance lifecycle (2025). Earlier releases, such as 5.4 and 5.3, have also transitioned to Sustaining Maintenance.
Although Infor still provide basic support if you log a call, these versions no longer receive:
- Software patches
- Bug fixes
- Maintenance releases
- Product enhancements
This means that if you encounter an issue, it's unlikely that a permanent software fix will be developed.
It is important to note that Infor does not classify products as "end of life" while customers continue to pay for maintenance. Instead, these versions move to a different stage of the product lifecycle, where the level of maintenance and support changes rather than ending altogether.
SunSystems and Microsoft
Another important consideration is the technology underneath your ERP system. Many older SunSystems versions rely on versions of Microsoft Windows Server and Microsoft SQL Server that are themselves approaching, or have already reached, end of support.
For example:
- SunSystems 6.2 was commonly deployed on Windows Server 2012, which is already out of Microsoft support
- SunSystems 6.3 can run on Windows Server 2019, giving it a little more lifespan
- SunSystems 4.4.2 surprisingly supports newer Microsoft platforms such as Windows Server 2022 and SQL Server 2022, despite being an older application
While the underlying operating system may still be supported, the SunSystems application itself is not. Running unsupported software increases operational and security risk over time.
Why consider moving to SunSystems Cloud?
Beyond remaining on a fully supported platform, one of the biggest advantages of SunSystems Cloud is the licensing model.
Traditional on-premise installations are licensed by module and user.
Many organisations only licensed the core modules, typically:
- Ledger Accounting
- Multi-Currency
Adding modules such as:
- Sales Order Processing
- Purchase Order Processing
- Fixed Assets
often meant purchasing licences for every user, even if only one or two people needed access. For smaller organisations, this often made additional functionality difficult to justify.
With SunSystems Cloud, all core modules are included within your subscription. This opens up opportunities to take advantage of functionality that may previously have been too expensive to implement.
For example, organisations can:
- Register and control purchase invoices using Purchase Order Processing
- Use Sales Order Processing for low-volume invoicing without significant additional licensing costs
- Introduce more structured financial processes without investing in additional user licences
For many businesses, this allows them to gain far more value from their ERP system than was practical with their legacy on-premise deployment.
Is it time to review your SunSystems roadmap?
If you're running anything earlier than SunSystems 6.4, it's worth reviewing your upgrade strategy.
Moving to a supported platform doesn't just reduce technical risk- it also gives you access to ongoing product innovation, new functionality and a simpler licensing model that can unlock capabilities your organisation may never have considered using before.
At Millennium Consulting, we've been helping organisations get the most from SunSystems for decades. Whether you're planning an upgrade, considering SunSystems Cloud, or simply want to understand your options, our experienced consultants can help you build the right roadmap for your business.

UK confirms Peppol as the standard for mandatory B2B e-invoicing
The UK government has confirmed (June 2026) that the Peppol network will be the core interoperability framework for its mandatory Business-to-Business (B2B) e-invoicing rollout.
The requirement will follow a phased rollout, beginning with large businesses and later extending to small and medium-sized enterprises. The initiative also aligns with HMRC’s Transformation Roadmap, which sets out the objective of a digital-first tax system by 2030. The model closely resembles Belgium’s first phase e-invoicing regime introduced from 2026.
Businesses may wish to begin internal planning ahead of 2029, including reviewing invoicing systems for structured invoice capabilities, assessing interoperability with ERP or accounting platforms. Early preparation will help organisations minimise implementation risk, avoid last-minute compliance challenges and unlock the wider operational benefits of digital invoicing.
At Millennium Consulting, we're already helping organisations prepare for this change, including delivering digital invoicing for a global Insurance business, multi-national Logistics company, and a plethora of European high street Retail businesses. Our experience enables finance teams to implement compliant, scalable solutions that improve efficiency while reducing manual processing and administrative overhead.
Get ready for mandatory e-invoicing
Whether you're planning your Peppol strategy, reviewing your finance systems or looking to automate your invoice processes, Millennium Consulting can help.

The Millennium Raising Futures KenyaGolf Day
£5,000 Raised at Millennium’s 20th Anniversary Charity Golf Day for Raising Futures Kenya
On Wednesday 17th June 2026, Millennium celebrated the 20th anniversary of its annual Raising Futures Kenya Golf Day at Ashford Golf Club in Kent. Marking two decades of fundraising and support for charitable causes, the event brought together clients, partners, suppliers, and friends for a memorable day on and off the course.
The weather was certainly on our side, providing perfect conditions for a competitive and thoroughly enjoyable day of golf whilst supporting a wonderful cause. Thanks to the generosity of everyone involved, the event raised an impressive £5,000 for Raising Futures Kenya.
After the golf, players gathered for post-round drinks and dinner, followed by an update from Leela Shanti of Raising Futures Kenya. Leela shared inspiring stories about the charity’s work and the incredible impact it continues to have in Kenya. She explained how funds raised through Millennium’s Golf Day directly support young people by providing training, education, and opportunities to help them build brighter, more secure futures.
Guests also enjoyed a Q&A session with rugby legend Peter Winterbottom MBE, alongside signed memorabilia, a lively game of Heads and Tails, a raffle, and the prize-giving ceremony, all of which contributed to a fantastic fundraising total.
A huge thank you goes to our generous supporters and sponsors, including Icorp, Infor SunSystems, IFS, Ashford Golf Club, Orsett Golf Club, Sene Valley Golf Club, Littlestone Golf Club, Balfour Winery, Florences, Wildwood, Kathmandu, and Tropic Skincare, whose support helped make the day such a success.
Thank you also to everyone who attended, donated prizes, purchased raffle tickets, and supported the event. As we celebrate 20 years of our Charity Golf Day, we are incredibly proud of what has been achieved together and grateful for the continued support that enables us to make a meaningful difference.

Millennium Digital Invoicing live in Belgium

Millennium Digital Invoicing live in Belgium
Digital invoicing is no longer optional — it is fast becoming a regulatory requirement across Europe.
Over the last six years Millennium has built deep, hands-on expertise supporting digital invoicing in Italy, one of Europe’s earliest and most demanding adopters. When Italy introduced mandatory electronic invoicing in 2019, Millennium was already in production, helping customers comply from day one. That experience is now paying off elsewhere.
We’re pleased to announce that Millennium Digital Invoicing now supports Belgium, enabling customers using Unit4 Financials by Coda to produce Peppol-compliant electronic invoices. From January 2026, we are live with our first Belgian customer.
Why this matters
Italy set the benchmark for digital invoicing in Europe with a complex, highly regulated, and fully mandatory model covering both inbound and outbound invoices. Millennium’s experience operating successfully in this environment demonstrates proven capability at scale, supporting multinational organisations by integrating Unit4 Financials by Coda data with third-party invoice sources in real-world, high-volume finance operations. From January 2026, Belgium will follow this trajectory, with B2B transactions legally requiring the issuance of structured electronic invoices via the Peppol network—making early preparation essential.
Looking ahead
Belgium is not an exception — it’s part of a broader European shift toward mandatory e-invoicing, driven by VAT control, fraud reduction, and tax transparency initiatives. Countries such as France, Germany, Spain, and others are already on the same path.
Millennium’s approach is simple:
- stay ahead of legislation
- minimise disruption to finance teams
- integrate seamlessly with existing Unit4 Financials by Coda processes
If your organisation is preparing for Peppol or future European e-invoicing mandates, now is the time to get ready.
