Enterprise Web Applications and Portals You Can Rely On
Connected to SAP, ERP and CRM. With access control and audit logging from day one.
When a company portal is slow or shows the wrong data, it costs money and trust. We build portals and internal tools that connect to your existing systems. For LANXESS, we have run a procurement catalog system with more than 5 million items since 2014.
- Security from the start: We build in access control, logging and compliance requirements from day one. Retrofitting costs more
- Cleanly integrated: We connect SAP, ERP and CRM. Your data then matches across all systems
- Start with an audit: After two weeks you know where your platform stands and what makes sense next. The audit costs €3,000 to €6,000 at a fixed price
Portals that speed up your business processes
When SAP, CRM and ERP are separate islands, your team retypes data from one system into another. Details get lost along the way. We build portals and tools that connect these systems. Customers, employees and partners then work with current data and stop copying things by hand. With well-planned integrations and easy-to-use interfaces, you save time and avoid errors.

A slow portal costs your employees time every day. An insecure portal costs trust and puts compliance at risk. We build portals that load fast and bring SAP, ERP and CRM together in one interface. At LANXESS, a catalog system with more than 5 million items runs this way.
We plan, build and operate. The platform grows as your business grows. We pay attention to load times, clean interfaces and security from the start. We host in Germany (Hetzner) or in your own infrastructure.

What we do best
Engineering overviewModular architecture
Independent components that you can maintain and extend one at a time. A monolith, by contrast, piles up technical debt every year.
Enterprise security
We implement single sign-on, roles and permissions, and audit logging, and we follow your compliance requirements.
Speed that matters
Every second of load time costs your employees working time. We build fast interfaces that also work on tablets and phones.

Built from modules
An enterprise solution that maps every process into one single block is hard to maintain and hard to change. We build portals from modules. Each module is tested and updated on its own while the rest of the system keeps running. Changes go live faster, and the risk stays small.
Two ways to start: an audit or an intro call
The Software Audit takes two weeks and costs €3,000 to €6,000 at a fixed price. You get an integration map, a risk backlog and a 90-day roadmap. In a free 30-minute intro call, we find out whether Onveda is the right fit. We work in English and German.
