Focus areas

API and ERP integration

Systems that knew nothing about each other exchange data. Inventory management to CRM, incoming invoices to accounting, online shop to ERP.

Azure Functions, REST, GraphQL, gRPC, Prisma

Web applications

Business applications from the form through the map view to the report. Currently WebGIS for general drainage planning and water supply.

Vue, Nuxt, Quasar, Node.js, TypeScript

Services and operations

Breaking grown monoliths into parts that can be run on their own, and running them in containers, in the cloud as well as on the client’s servers.

Go, Kubernetes, Docker, PostgreSQL

Plugins

UID check

WordPress plugin: validates the Swiss UID (company ID) in the WooCommerce checkout against the federal UID register. Version for bexio: contact and check note in bexio, free for 30 days, then CHF 79 per year and shop.

bexio form connector

WordPress plugin: website enquiries become contact and quote in bexio, no retyping. One-time price, no subscription.

bexio ↔ HubSpot

Integration with nothing to install: a won HubSpot deal becomes a quote or invoice in bexio, and the payment status flows back into the deal. Free for 30 days, then CHF 29 per month.

KLARA shop connector

Plugin for WooCommerce and Shopware: every order becomes customer and invoice in KLARA, with Swiss VAT. CHF 149 per shop and year.

AbaNinja shop connector

WordPress plugin: every WooCommerce order becomes address and invoice in AbaNinja, total exact to the centime. CHF 149 per shop and year.

5-centime rounding for WooCommerce

Free plugin: total rounded to 5 centimes, difference as a separate line without VAT.

All plugins at a glance

What an integration looks like

Existing system

Client’s ERP

Invoices arrive as PDF and have to be entered by hand.

Invoice PDF
structured JSON

built by me

Service on Azure

Reads the document and returns it as structured JSON.

This lets the ERP book incoming invoices itself instead of having them retyped. Users can train the service on the invoices that matter. Built with TypeScript, Node.js and Prisma.
