Notes

Notes from custom development

Practical notes on pricing, interfaces, integrations, e-shops and working with AI. We write about decisions that affect day-to-day operations, not about general trends.

Deciding

A website, an e-shop, or a custom application?

When WooCommerce is enough and when it is not

The real limits are not in the product count but in the rules of the sale.
