All for One and VINCI: What SAP Customers Can Expect
7 min read
The SAP partner that thousands of SMEs rely on to transition to S/4HANA is set to get a new owner. VINCI Energies is offering €67.50 per share for All for One and plans to integrate the company with its ICT brand Axians. For existing customers, the purchase price matters less than whether the promises of autonomy will survive the deal.
Key Takeaways
- Familiar partner, potential new owner: All for One remains the SAP service provider for more than 4,500 SMEs, but if the offer succeeds, it will belong to the French VINCI Group.
- Continuity is contractually guaranteed: The Filderstadt headquarters will remain, and a domination agreement is ruled out until 2029. Ongoing projects will not be affected initially.
- Expanded reach and portfolio: Axians brings networks, cloud and cybersecurity to the table, along with access to a pan-European customer network.

On 16 July, All for One signed a business combination agreement with a subsidiary of VINCI Energies. The French group is launching a public takeover bid, which the board of directors and supervisory board have already endorsed. For the many SMEs that rely on All for One as their SAP partner, this is at first a matter for careful consideration-though not a cause for concern. What matters is what lies behind the offer and what has been contractually secured.
What’s driving the offer
All for One is one of the leading SAP service providers for SMEs in Germany, Austria, Poland and Switzerland. Behind the offer is the French VINCI Group, which posted €75 billion in revenue across 120 countries. Through its VINCI Energies division and its digital brand Axians, it consolidates fibre-optic networks, data centres, network infrastructure and cybersecurity.
The group does not aim to replace what All for One already delivers; instead, it seeks to complement it. Axians provides the technical backbone, while All for One supplies SAP consulting and the operation of business applications on top of it. Combined, the two should be able to serve customers from network connectivity all the way to finished business processes. For SMEs, that means, in perspective, more services from a single partner backed by a larger organisation.
What is a business combination agreement? A business combination agreement-known in English as a Business Combination Agreement-is a contract between a buyer and the target company. It sets out the terms of a proposed takeover, including price, autonomy guarantees and future governance. It is not yet a closing document. The takeover only becomes effective once shareholders have accepted the bid and regulatory approval has been granted.
What SMEs see in All for One
All for One’s value lies in its proximity to the German Mittelstand. The company supports more than 4,500 customers through the switch to S/4HANA, the digital core of modern SAP landscapes. Migration is handled via the CONVERSION/4 programme, moving clients away from legacy ERP systems whose maintenance is nearing its end. Anyone facing this transition knows the pressure of tight deadlines.
It is precisely this close customer relationship that makes the firm attractive to a potential buyer. Once customers hand their SAP processes to a partner, they tend to stay for years. The business model delivers recurring revenue because maintenance and operations run continuously. For existing customers, that is good news: their partner is in demand, not in distress.
Why Axians is interested
In 2025, Axians generated €3.8 billion in revenue with 18,300 employees. The larger share comes from digital infrastructure such as networks and data centres, while a growing portion is derived from services like data analytics, the digital workplace and cyber-security-areas many SMEs previously had to source elsewhere.
All for One itself views the move as an opportunity for growth rather than a loss of independence. CEO Michael Zitz frames it this way:
“For All for One, the takeover offer marks the beginning of a new chapter.”
– Michael Zitz, CEO All for One Group, in the company press release dated 16 July 2026
Why autonomy pledges matter most
For existing customers, the most important clause is the one on autonomy-not the price tag. All for One will keep its headquarters and main administration in Filderstadt. A domination and profit-and-loss transfer agreement is ruled out until 1 January 2029. As long as VINCI does not own every share, at least one independent supervisory-board member will remain on the board.
These pledges are more than symbolic. They guarantee that, for the next few years, All for One will make its own decisions with familiar contacts and stable structures. For customers in the middle of an S/4HANA migration, this predictability is crucial. Whether the larger group will exert more influence later remains to be seen, but the framework for the coming years is now set.
What existing customers should do now
No immediate action is required. Existing contracts and projects remain unchanged until the deal is finalised. Still, it makes sense to keep a close eye on developments and keep an eye on a few key points.
Keep calm
- Ongoing S/4HANA projects and service contracts remain valid.
- Headquarters and contacts in Filderstadt are guaranteed.
- Autonomy is contractually secured until 2029.
Keep watching
- Will your fixed contacts remain after closing?
- Does the performance and pricing model change with the expanded portfolio?
- Are new network and security offerings on the table that you might want to use?
If you have an SAP-related decision coming up in the next few months, raise these points in your next conversation with your contact. A new owner will not immediately alter day-to-day operations, but asking the right question at the right time can spare you surprises down the road.
Frequently Asked Questions
Has All for One now been taken over by VINCI?
Not yet. A merger agreement has been signed that outlines a planned takeover offer. It will only take effect once enough shareholders accept and the antitrust authorities approve.
Will anything change for me as an SAP customer?
Not in the short term. Contracts, projects, and contacts remain unchanged. The agreement also guarantees All for One’s independence and its Filderstadt site until at least 2029.
What does Axians bring to me as a customer?
Axians expands the SAP offering with networking, cloud, data centers, and cybersecurity. In the long run, this allows bundling services that many mid-sized companies currently source from multiple providers.
Why is the offer so much higher than the stock price?
The premium reflects the value of a stable mid-market customer base with recurring revenue. Such relationships are hard to build and therefore highly sought after.
Should I postpone an upcoming SAP migration?
There’s no reason to do so. Migrations follow SAP’s maintenance schedules, not ownership changes. It’s wise, however, to document fixed contacts and terms in your current project.
