Sweden (SIGN SE)
Sweden requires every cash register receiving cash payments to issue receipts signed by a certified control system. Traditionally this meant dedicated hardware Control Units (kontrollenheter) physically attached to each POS. With the introduction of cloud-based control systems by Skatteverket, the same compliance can now be achieved purely through software — and fiskaly replaces the physical control unit with a cloud-based API: same compliance, no hardware.
At a glance
Section titled “At a glance”| Regulation | Real-time signing of cash register transactions through a certified cloud-based control system, governed by SFS 2007:592 (Cash Register Act) and SKVFS 2020:9 (Control System Regulations). |
| What it requires | An organisation number (organisationsnummer), registration of the control system and cash register with Skatteverket, a stable internet connection, and printing of mandatory receipt fields including the tillverkningsnummer and control code. |
| Integration effort | Standard UAPI integration — same resource model as SIGN DE, SIGN IT, SIGN FR. Sweden-specific payload fields and compliance artifacts are the only differences. |
SIGN SE is built on the fiskaly Unified API. Integrate once, and adding Italy, France, Germany, or Portugal means changing the payload schema — not rewriting your integration.
