SaaS without an API
When a vendor provides no interface, we go via export files, web services or direct database access.

Custom Interfaces & APIs
Whether SaaS tools, legacy systems or industry solutions. We build custom interfaces and APIs for almost any combination. Including data transformation, error handling, logging and monitoring. Operated in the cloud or on-premise.
Interfaces & APIs at a glance
Most companies run a dozen systems that work well individually but don't talk to each other. The result is media breaks: data is exported, reformatted, transferred by hand — error-prone and slow. We close these gaps with custom interfaces that map exactly the fields, rules and edge cases that actually occur in your business.
The hard part of an integration is rarely the happy path but everything around it: different data formats, time zones, rounding, partial failures, retry logic. We develop interfaces with clean data transformation and robust error handling, including logging and monitoring so problems surface before they reach daily operations.
Where an API is missing, we find a way via web services, file import or database access. The result is continuous data flows between ERP, shop, CRM, accounting, logistics and production — maintainably documented and without dependence on a single provider.
Interfaces & APIs: what we deliver
ERP ↔ webshop / marketplace
CRM ↔ marketing automation
Warehouse ↔ logistics provider
Accounting ↔ bank / payment provider
Industrial machines ↔ cloud dashboards (IoT)
Data transformation, logging and monitoring
Use cases
Interfaces & APIs in practice
// 02
Machine data to the cloud
Values from production land in a dashboard instead of being read off the machine and typed into Excel.
// 03
Reconciling payments
Bank movements are matched to open items automatically, with exceptions going to a review list.
How we proceed
Interfaces & APIs: step by step
Record the systems, the data fields and the edge cases
Define the transformation, the failure cases and the retries
Build against test data, then run in parallel
Switch over, monitor, hand over the documentation
FAQ
Interfaces & APIs: frequently asked questions
Still have open questions? We're happy to clarify them in an initial call.
- Then we use alternatives such as web services, file import/export or direct database access. Even older systems can usually be connected reliably this way.
- Every interface receives error handling, retry logic and monitoring. Faults are reported and logged so they can be fixed quickly — instead of silently losing data.
- You do. You receive the source code, the configuration and the documentation. If you later take over operation yourself or move it to another provider, that works without our involvement.
