How we work
- The conversation and the prototype are free. We show a working demo within a week, and the price comes only after it.
- A business website starts from 1000 zł net, care after launch from 100 zł net per month. Stores, apps and systems are quoted after the prototype.
- For a month after launch we fix bugs and make changes within the agreed scope at no extra cost.
- We do not design boards or housings, and we do not promise the first place in Google for a given phrase. If a website builder is enough for a company, we say so.
Website audit
The only service with a fixed price list: a scored report for 249 zł net, ready in 2 working days from payment. Ordered on the site, no call needed.
