Compliance
Operating a cash register comes with legal obligations that vary by country. Some countries require integration with a certified fiscal control unit, while others only require a digital record of transactions. Avvyr supports both scenarios.
How fiscal registration works
When using Register mode, Avvyr can integrate with a control unit — a certified hardware device that fiscally registers each transaction. The control unit generates a control code, sequence number, and register ID that are printed on every receipt, as required by local regulations.
This data is included on every receipt and can be audited by tax authorities. The control unit information is also stored on the order for record-keeping.
Where Avvyr is certified
Avvyr holds fiscal certification with hardware control unit integration in the following countries. Expand each country to see details about requirements and registration.
Status: Fully certified with control unit integration.
Sweden requires all cash registers to be connected to a certified control unit that fiscally signs each transaction, per Skatteverket's regulations.
What you need to do:
- Register your cash register with Skatteverket before you start using it. This is a legal requirement. You register via Skatteverket's e-service or by submitting form SKV 4705.
- Connect a certified control unit — Avvyr integrates with certified control units that handle the fiscal signing of every transaction.
- Display your registration certificate — After registration, you receive a certificate that must be visible at the point of sale.
- Ensure receipt compliance — Every receipt must include the control unit's control code, register ID, and sequential receipt number. Avvyr handles this automatically.
Avvyr handles automatically:
- Fiscal signing of every transaction via the connected control unit.
- Control code, register ID, and sequence number on every receipt.
- Z-reports with correct VAT breakdown (25%, 12%, 6%).
- Audit-ready transaction logging and journal export.

Countries without control unit requirements
Many countries do not require integration with a certified hardware control unit to operate a cash register. In these countries, Avvyr's POS can be used directly without additional fiscal hardware.
In all of the above markets, Avvyr's built-in transaction logging, receipt generation, Z-reports, and journal export provide the digital record-keeping needed for tax compliance.
Expanding to new markets
Avvyr is actively expanding fiscal compliance support to new countries and regions. If you operate in a country not listed above — or in a country with specific fiscal device requirements — we want to hear from you.
We evaluate new markets based on customer demand and regulatory requirements. In many cases, we can work with you to assess what's needed and prioritize certification for your region.
Control unit fallback
In certain situations where the control unit is temporarily unavailable (e.g., hardware malfunction or connectivity issues), the system falls back to a cash invoice mode. When this happens:
- The receipt is marked to indicate that the control unit was not accessible.
- The transaction is still recorded in the system.
- Normal fiscal registration resumes automatically when the control unit becomes available again.
This ensures that sales can continue even during temporary hardware issues, while maintaining a clear audit trail.
What appears on receipts
When a control unit is active, every receipt includes:
| Field | Description |
|---|---|
| Control code | The fiscal control code for this transaction. |
| Register ID | The fiscal register identifier. |
| Receipt number | Sequential receipt number from the control unit. |
| Manufacturer | Control unit manufacturer. |
| Model | Control unit model. |
This information is required for tax audits and must be present on all fiscally registered receipts.
VAT handling
Receipts display VAT broken down by the applicable rates for your market. The specific VAT rates depend on the country and product categories in your catalog. Avvyr calculates and displays the correct VAT breakdown automatically based on your market and product configuration.
