How we think about technology

Practical experience from product development, POS and payment integrations, AI agents and operating our own systems.

We write about things we solve, test or use ourselves.

How to connect POS, payments and fiscal systems without replacing everything

A practical explanation of the integration layer between POS, payments, fiscal systems, devices and cloud services.

How to distinguish a prototype, proof of concept, pilot and production — and what must be tested beyond the ideal scenario.

The difference between answering and acting, the architecture of an agentic system, and control over its tools.

What makes up the price of a first version, which line items to check in a quote, and how to compare budgets from different vendors.

Where AI tools genuinely help during development, what stays the vendor's responsibility, and what to clarify before placing an order.

A finished app is not proof of interest. How to choose the smallest meaningful test and what to look for.
