We fix the gaps SAP FSA customers actually hit.
Altiwerk builds focused extensions for SAP Field Service and Asset Management (formerly SAP FSM). Useful additions that fit inside the FSA Shell — not platforms, not replacements, not "rip and replace" projects.
Why we exist
SAP FSA is a strong core for field service operations. But every real customer eventually hits the same kind of wall: "if only it could also show this view", "if only this UDO had a proper screen", "if only we could see the live S/4 stock figure without bouncing tabs."
These gaps are too small to justify a custom development project, and too specific for SAP to ship. The result: customers either pay consultants for one-off iframe hacks, or just live with the gap.
We think there's a better path — products, not projects. Each of our extensions is a real product: licensed, supported, maintained across customers. You get the fix without the consulting bill.
What we won't do
- No tenant data on our servers. Our backend validates licenses. FSA API calls go straight from the browser to your FSA cluster, and S/4 calls go through an engine running on your own BTP.
- No lock-in. Screens you build are stored in your FSA tenant as FSA records, not on our infrastructure. If you stop renewing, your data stays.
- No surprise expansion. We don't auto-upgrade you onto a bigger SKU. You bought Single? You stay Single until you tell us otherwise.
- No consulting bait-and-switch. The price is the price. We'll help you get installed, but we don't sell hours.
How we work
FSA Shell first
Every extension lives inside the FSA UI your users already use — on the desktop Shell and in the mobile Web Container. No separate logins, no separate hosting decisions on your side.
Customer-driven roadmap
What we build next is shaped by what current FSA customers ask for. We don't build features in a vacuum — we build them because a paying customer needed them yesterday.
Product, not project
Everything we ship is maintained across customers. Bug fixes you got? Every other customer gets them too. Improvements they paid for? You get them for free.
Honest about scope
We're small and focused. If your problem is bigger than what an FSA extension can solve, we'll tell you instead of selling you one.
