Clean data flows between your systems
ERP, CRM, PIM, DMS, or your custom tool: Data flows automatically, bidirectionally, and traceably. No manual copying, no CSV imports.
LEAN Stability: API Integrations for ERP and CRM
Systems connected.
Without drama.
Your ERP says A, your CRM says B, and somewhere in between, data is lost. We build clean integrations – SAP, Dynamics, Salesforce, Odoo – with clear API contracts instead of Excel mappings.
What's it about?
For companies whose systems do not communicate with each other. For teams that manually synchronize data between ERP, CRM, and third-party systems. For IT departments that worry about their interfaces after every update.
We bring you:
- Connection speed ↑
- Data quality ↑
- Production errors ↓
Do you know this?
What does this bring you?
Faster connection of new systems
Once set up cleanly, every additional system can be easily added. The architecture scales instead of breaking apart with every new requirement.
Fewer production errors
Validation, error handling, and logging for every data flow. Erroneous records are caught, not silently passed through.
Interfaces that survive updates
Clear API contracts with versioning and error handling. If a system changes, you know immediately what breaks – not just through a customer call.
Pilot Phase
Deliver first, then commit. That’s what the pilot is for.

Frequently Asked Questions
FAQ
Which systems can you connect?
SAP, Dynamics 365, Salesforce, Odoo, HubSpot, Navision – and anything that has an API. If no standard API exists, we build adapters. In the assessment, we clarify what your target system can and cannot do.
Do we have to replace our existing integrations?
Not necessarily. If existing interfaces work, we leave them. We start where it burns – the fragile, undocumented, manual flows. Replace step by step instead of a big bang.
What happens if a system changes its API?
For this, we build API contracts with versioning. If an endpoint changes, the test fails – not production. Monitoring and alerting immediately show where something breaks.
Do we need middleware or is a direct connection sufficient?
It depends on the complexity. For 2-3 systems, a direct connection may suffice. From 4+ systems or bidirectional flows, we recommend a middleware layer – for decoupling, error handling, and scalability.
How do you ensure data consistency?
Validation at every interface, error handling with retry logic, dead-letter queues for unprocessable records, and logging for every flow. In the pilot, we demonstrate this with 3 concrete use cases.
What is the pilot phase?
A clearly defined project with a defined scope – typically 4-12 weeks. At the end, you don’t get a concept paper, but a functioning result: real code, tested and deployed. The pilot shows you what we can do before you decide long-term.
What happens after the pilot phase?
After the pilot comes the proof: We look together at the results – what worked, what was worthwhile, where are the gaps? Everything measured against defined KPIs, not gut feeling. Based on this, you decide: scale, adjust, or stop. No pressure, no upselling. If the proof convinces, we go into scale – your project grows, your team grows with it, the knowledge stays with you.
Do I have to start with a pilot phase?
No. The pilot is our recommended entry point because it creates clarity for both sides – but it’s not a must. If you already know what you need and want to get started right away, we can also join an ongoing project or start directly with a larger scope. We adapt to your pace.
Do you work T&M or fixed price?
Start as a timeboxed pilot in T&M (optionally with a cap). No fixed price risk, no lock-in. You see at any time what you are paying for – and can stop at any time. But very few do.
