Company
Built in Espoo, for the counters we know.
Fizzy is made by a small, hands-on team at Fidanet Solution Oy. We're building the sealed, tax-authority-ready point of sale we wished existed, and shipping it to the retailers, restaurants and shops we know personally.

The story
It started at the counter.
Every small business knows the quarterly panic: sales that were guessed rather than recorded, receipts lost on the way to the accountant, and a tax office that expects the numbers to add up. Fizzy started there: with a till that records every sale once, seals it, and never lets it be quietly changed. Then we certified the payments with Worldline so the money and the record can never disagree. We keep it simple on purpose. Our whole job is making an operation this simple stop feeling this hard.
What we stand for
Four principles. Everything else is opinion.
Audit-safe by default
Every sale is sealed and every classification shows its rule. Re-run any decision a year later, same answer.
EU-only data
Servers in the EU. Your data never leaves the region: no US sub-processors, GDPR by design.
Deterministic AI
Fizzy applies a rule and shows the work. It doesn't make a creative guess about your numbers.
Product over projects
One platform; every improvement ships to every customer. We're a product company, not an agency.
A small team, building trust into every sale.
Six people. Small enough that the person who answers your email is the person who wrote the code, and no counter problem gets handed down a queue.
Fidanet Solution Oy.
Fizzy, and its sister product Baslic, the auditable tax engine, are built by Fidanet Solution Oy, a Finnish company registered in Espoo. Bootstrapped, hands-on, and currently a small team. Together the two products form one auditable money trail: from the money coming in at the counter to the tax return going out.
