Every sale, sealed at the source.
The point of sale and money-in platform for any business that takes payment: retail, hospitality, trade. Each transaction is written once to a tamper-proof ledger, reconciled to a Worldline-certified payment, and turned into data your accountant, your ERP and the tax office can trust.

The difference
A cash register records a sale.
Fizzy proves it.
Most tills store a number you have to trust. Fizzy writes every sale, void and refund to an append-only ledger, each entry sealed with a hash, timestamp and staff ID, then turns it into structured data on the way out. The money that came in and the record of it can never quietly disagree.
What Fizzy does
Three things a generic till can't.
The sealed ledger
Every sale, void and refund: hash-chained, append-only, impossible to quietly change. The daily close and the SAF-T export come out of the same record the tax office would ask for.

The platform
One immutable spine, from the first tap to the tax return.
Fizzy isn't a till with reports bolted on. It's a money-in operating system: every capability builds on the same sealed ledger, so the counter becomes the trusted source of truth for the whole business.

Sealed Ledger
The tamper-proof heart. Every sale, void and refund hash-chained and append-only: the foundation every other module writes to.

Also shipping
And the rest of what a counter has to do.
None of it is a separate subscription, and all of it writes to the same sealed ledger. Which means the day's takings, the staff hours behind them and the stock they consumed are one record, not three systems to reconcile on a Sunday.

Trust & compliance
Everything a generic till hopes it's doing, proven.
Immutable ledger
Append-only and hash-sealed. No sale is silently changed or deleted, and the sequence can be replayed end to end.
Worldline & PCI-DSS
Certified payment infrastructure. Card data is handled on the terminal and never touches your device or our servers.
Deterministic AI
Rule-driven, not model-generated. Every number traces back to a rule and the exact rows behind it.
EU and Nordic data
Hosted in the European Union, GDPR by design, with isolation enforced between tenants at the data layer.
SAF-T & Z-report
Standard audit files and daily closings, export-ready in the format the authority expects.
Offline-first
Sales never stop when the network does; everything syncs, sealed, the moment the counter is back.
One period, four ways, off the same sealed rows: how it was paid, which counter it came in through, the VAT each rate carries, and what actually sold. Nothing here is typed in or reconciled afterwards. It is the same events the register wrote.
