01 · CONTEXT

Portuguese taxi fleets run on a certified taximeter that is the legal source of the fare, and a software chain that should carry that figure through to the invoice. In practice the chain is broken in the middle.

02 · THE PROBLEM

The existing flow keeps the total and discards everything else: distance, duration, tolls, supplements, route, and the taximeter's own trip number. The driver retypes the fare by hand into a second app while the passenger waits.

03 · WHAT WE BUILT

Capture straight from the meter.The trip arrives in the app already complete, deduplicated and correlated, so nothing is retyped and nothing is lost between the meter and the invoice.

Immediate, editable, auditable receipt.The full breakdown appears in seconds, with distance computed from device GPS. The driver can adjust the fare, and the system stores both the meter value and the charged value.

Built to fiscal requirements.Built to Portuguese fiscal requirements: invoices carry the SAF-T hash chain, QR and ATCUD the regulation asks for. Certification with the Tax Authority is in progress.

Works without coverage.An idempotent local queue and a complete on-device trip ledger. Offline, the passenger gets a provisional receipt and everything syncs when the connection returns, so a shift in a dead zone loses no trips and nothing duplicates.

04 · WHAT HELD

The architecture separates two things most implementations conflate: printing and invoicing. A printer failure cannot lose an invoice, and a network failure cannot stop the passenger walking away with a provisional receipt. Every trip is logged locally, including the ones the driver discards, so the fleet owner's reconciliation always balances.
