ERP and Business Central
Exchange orders, items, customer data, and documents between apps, flows, and Microsoft Dynamics 365 Business Central.
Integrations & APIs
Your systems. Connected at last.
The best processes do not stop at the boundary of Microsoft 365. I connect Power Automate and Power Apps with ERP, accounting, CRM, signature services, and your own applications - via existing connectors, HTTP calls, or custom connectors.
- REST · SOAP APIs of all kinds
- Custom connectors reusable and secure
- PL-400 Power Platform Developer
01Use cases
What I use integrations & APIs for
Accounting
Automatically send invoices, accounting documents, and contacts to accounting systems such as sevDesk or Lexware, or retrieve them from those systems.
Digital signature
Send contracts and documents for signature via Adobe Acrobat Sign, track the status, and file the result.
CRM and sales
Synchronize contacts, inquiries, and cases between CRM and Microsoft 365 - including through older SOAP APIs.
Microsoft Graph and Power BI API
Manage users, groups, teams, calendars, files, and reports programmatically.
Custom connectors
Your API as a custom connector with OAuth 2.0 or an API key: built once, usable in all apps and flows.
02Approach
From the first conversation to a solution in production.
Consulting and implementation from a single source: whoever writes the concept also builds it - with no friction between consultant and developer.
-
Initial consultation
Free and without obligation via Microsoft Teams: What is the challenge, what is the goal, and which licenses do you already have? Afterward, you will know whether and how the Power Platform fits your needs.
-
Process analysis
Together with the people who run the process every day: How does it work today, and where do manual handoffs between systems or media, delays, and errors occur?
-
Solution concept
Data model, screens, flows, permissions, and licensing - in writing, easy to understand, and with a clear effort estimate.
-
Implementation in stages
Short iterations, each with a working interim result. You see early on what is being built and can adjust course.
-
Rollout and handover
Acceptance, deployment to production, documentation, and handover to your team - so the solution does not depend on me.
-
Further development
If you wish, I will continue to support the solution afterward: enhancements, new requirements, and updates from Microsoft.

Specialist retailer of fireplaces and stoves with delivery and installationsince 02/2022
Order processing for a stove retailer with Power Apps and SharePoint
For almost five years, I developed the central order processing system for a fireplace and stove retailer with several companies and locations, based on SharePoint, Power Automate, and Power Apps, and I still support it today. Quotes with digital signatures, invoices and payment reminders via sevDesk, Planner tasks, customer surveys with Forms, Power BI, and a mobile installation report on tablets all work together. The solution gave rise to the industry platform FLAMOX365.

Digital quality inspection with Power Apps in precision machining
For a manufacturer of precision turned and milled parts, I designed and implemented a responsive canvas app for quality inspections in production. It determines which inspection characteristics are due for each machine, part, and inspection trigger, evaluates measured values against tolerances, and stores the results in an auditable form in SharePoint, with versioning and restricted editing rights. In addition, I advise on migrating an existing production app that has evolved over time into separate environments.

Procurement and employee training with Power Apps at an automotive supplier
For an automotive supplier, I digitized internal request processes with the Microsoft Power Platform. A canvas app for purchase requests to procurement has been in use company-wide since 2023; a second app covers seminar requests from application to feedback. Around 100 cloud flows control approvals, reminders, Planner tasks, and the automatic synchronization of HR data.

05Questions and answers
Frequently asked questions
Our system has no ready-made connector - is it still possible?
Usually yes. If the system has a REST or SOAP API, I build a custom connector or call the API directly from Power Automate. If there is no API, a desktop flow (RPA) can serve as a bridge.
How are integration credentials protected?
Credentials do not belong in flows or apps. I use connections with OAuth, environment variables of type "Secret" with Azure Key Vault, and service accounts with only the permissions they need.
