Norway’s Cash Register Rules: What POS Suppliers and Retailers Need to Know

Norway requires compliant cash register software, traceable sales records and a supplier’s product declaration. A September webinar explained the roles of POS providers and retailers, the move to the renewed Altinn portal, and the separate B2B e-invoicing and digital bookkeeping deadlines.

Norway’s fiscalization model places considerable responsibility on the cash register system supplier. A POS system offered to businesses with bookkeeping obligations must meet technical requirements, record transactions in an electronic journal and be covered by a product declaration submitted by its supplier. Retailers, in turn, must use a compliant system and follow the rules for recording cash sales.

These responsibilities were the focus of Fiscal Solutions’ September webinar on Norway. The session also addressed a practical question for retailers developing their own POS software and explained how upcoming e-invoicing rules fit alongside the existing cash register requirements.

What counts as a cash sale?
For Norwegian cash register purposes, a cash sale is broader than a payment made with banknotes or coins. It generally involves payment when goods or services are delivered and can include payment by card or a mobile payment method. The way a customer pays therefore matters, but so does when the payment takes place.

The webinar distinguished these transactions from credit sales and internet sales. It also discussed cash on delivery, where an order and its payment flow do not necessarily amount to a cash sale at the retailer’s POS. Businesses should assess the actual sales process before deciding which transactions belong in the cash register.

Norway does not require each POS transaction to be transmitted to the Tax Administration for real-time approval. Instead, the system must create reliable records that can be examined later. This makes the integrity of the software, its reports and its electronic journal central to compliance.

The POS system must preserve an audit trail
The webinar described several functions that a compliant system must support, including issuing receipts, registering returns, producing required reports and maintaining an electronic journal. Transactions must be digitally signed in accordance with the technical rules. The system must also be able to export relevant data in the SAF-T Cash Register format for inspection.

The electronic journal covers more than completed sales. Depending on the system’s functions, it can record events such as opening a cash drawer, checking or changing prices, and continued use of the register. These records help an auditor understand what happened at the till, including actions that did not result in a sale.

System designers have room to add functions, but that flexibility has limits. An additional feature must not undermine mandatory controls or introduce a prohibited function. Suppliers also need to describe relevant functions clearly in their product declaration so that the Tax Administration can understand and examine how the system works.

The supplier is responsible for the product declaration
The Declaration of Conformity, also referred to as the product declaration, is submitted by the cash register system supplier. It identifies the supplier and system and describes how the product meets Norway’s requirements. The Tax Administration publishes a list of systems with product declarations, which retailers can consult when selecting a solution. Foreign suppliers offering systems on the Norwegian market are also subject to the declaration rules.

The declaration is an ongoing supplier responsibility. If a change to the system affects its declared functions or compliance, the supplier must assess whether the declaration needs updating before the changed product is offered. Retailers should therefore ask their provider how changes are controlled and how the declared product relates to the version they use.

During the webinar’s question session, a participant asked whether a supplier could market a system immediately after submitting its declaration. The speaker, Ivana Picajkić, Medior Legal Consultant at Fiscal Solutions,  advised waiting for the Tax Administration’s response: if the declaration or system requires correction, early sales can create problems for customers. That was the speaker’s practical recommendation, rather than a stated waiting period in the rule.

In-house development requires attention to legal roles
A retailer developing a POS system for its own stores may face a particular difficulty: the webinar explained that the business using the system and the entity supplying and declaring it must have distinct legal roles. One approach discussed was to establish a separate legal entity to develop, supply and declare the system, while the retailer uses it in its stores.

This is a structural decision, not simply a change to a company department’s name. A retailer considering in-house development should establish who legally supplies the product, who submits the declaration and who remains responsible for compliance and subsequent changes.

Submitting the declaration also requires the right digital access. The webinar explained that Altinn manages the authority to act on behalf of the supplier, while the declaration itself is submitted through the Tax Administration’s service. Following changes to Altinn access management in June 2026, suppliers should check that their representatives have the permissions needed to submit on the company’s behalf.

E-invoicing is a separate change
The webinar closed with Norway’s next digital obligations. From 1 January 2027, businesses within the scope of the bookkeeping rules must send structured electronic invoices for covered business transactions. From 1 January 2030, the rules introduce the requirement to use a digital accounting system and receive electronic invoices. Norway enacted the changes in June 2026, with the bookkeeping provisions taking effect on those respective dates.

An ordinary PDF is not, by itself, a structured e-invoice that accounting software can process automatically. Businesses should therefore review their invoicing and accounting systems ahead of the deadlines. The new obligations concern business invoicing and bookkeeping; they do not replace the cash register rules for retail sales.

For POS suppliers, the immediate priorities remain a compliant product, a clear declaration and an electronic journal that can produce the required records. Retailers should confirm that their system is covered by a product declaration and review how their sales are classified and recorded. Businesses that also issue B2B invoices have a second workstream: preparing those invoice and accounting processes for 2027 and 2030.
