Sound familiar? This is what everyday life is like for construction companies in Norway.

If these situations are close to you, it's a sign that it's worth sorting out costs and reporting.

Money "leaks" through fingers

You run projects, but at the end you find that the profitability is much lower than you expected. “Again, at the end of the project, the budget didn’t come together, and I don’t know why.”

Fear of inspection and messy paperwork

Invoices get lost, contracts are in different places, and you are not sure if everything is billed correctly. “Are you sure I haven’t forgotten anything? What if an inspection comes?”

Management "in the fog"

You make key decisions without access to up-to-date financial data, relying on hunches. “I need those numbers yesterday, not three weeks from now.”

Every day without cost control is money you won't get back.

Why is it riskier than ever to ignore this problem NOW?

⚡ Tougher Skatteetaten and Arbeidstilsynet inspections and DiBK requirements increase the risk of penalties when records and accounts are not perfectly maintained. The construction market in Norway is changing dynamically. What worked yesterday can generate losses and serious legal risks today. Staying behind is not an option.

Growing pressure on margins

Material prices and labor costs are constantly rising. Companies that cannot accurately calculate and control the profitability of each project will simply go out of business. Competitors that do this will take your orders.

Tighter and tighter system

The Norwegian Tax Administration (Skatteetaten) and the Labor Inspectorate (Arbeidstilsynet) are introducing new requirements and tightening the system every year. The Direktoratet for byggkvalitet (DiBK) requires Sentral godkjenning, and the NAV controls the correctness of the posting of workers. Half-measures and “cheap accounting” are an easy route to severe financial penalties.

Digitization is a must

Modern tools give your competition an edge – access to real-time data. Basing decisions on hunches when others base them on hard numbers is a strategic mistake you can’t afford to make.

An investment in peace of mind that costs less than one major mistake.

⚡ Construction companies that have ongoing cost control save an average of NOK 40-80,000 per year in avoided penalties and tax optimization.

Many of our customers thought we were “expensive.” Today they know that the lack of control over margins and taxes has cost them much more. Let’s see the numbers.

The most common questions about construction accounting in Norway

We have collected the most common questions to clear up doubts before the launch.

How much does accounting cost for a construction company in Norway?

The cost depends on the number of projects, employees and subcontractors, and whether you handle Byggekort, delegations and payroll. We start with a brief diagnosis and cost simulation, so you have full predictability. In practice, the service pays for itself through better margins, cost control and avoided penalties.

How is construction accounting different from regular accounting?

In construction, it's the project that counts, not just the invoices. There is subcontractor billing, timeføring, solidaransvar, Byggekort/HMS-kort, MVA and payroll. We do the accounting so that you see project profitability and cash flow over time, not after the fact.

What does it look like to change an accounting firm in a construction company?

The change is simple and with no downtime. We take over 99% of the paperwork, contact with the previous office and document transfer. We determine the scope, implement the document transfer process and get your projects in order right away. You make the decision, we deliver a smooth transition.

Do you represent construction companies before Skatteetaten and Arbeidstilsynet?

Yes. We act as a formal representative before Skatteetaten, Arbeidstilsynet and NAV. We take over communications, respond to inquiries and keep an eye on MVA deadlines, payroll and industry obligations. This gives you peace of mind and minimizes the risk of penalties.

I already have an accounting office in Poland. How does the cooperation look like?

This is a common model. We act as the Norwegian financial branch of your construction company. We exchange data with the office in Poland, take care of consistency of documents and conformity of accounts in both countries. You have a single view of finances and a clear division of responsibilities.

How does uploading documents from construction sites work in practice?

We work 100% digitally. You send invoices, contracts and estimates from construction sites via an app on your phone or email. All you need is a photo, and the document goes into the system and we assign it to the project. This way nothing is lost and the reports are up to date.

What are the accounting requirements for a construction company in Norway (Byggekort, subcontractors)?

The construction company must keep timeføring, account for subcontractors with solidaransvar, have HMS-kort and often operate Byggekort. Skatteetaten especially controls MVA and wages. We keep records so that they are compliant and ready for inspection.

Do I need Sentral godkjenning and Byggekort?

Sentral godkjenning is not mandatory, but often makes it easier to win contracts. Byggekort/HMS-kort are required on many construction sites and must be billed correctly. We help with documentation and compliance to meet the requirements of principals and authorities.

How to account for employees posted from Poland in a construction company in Norway?

Posted workers must have an A1-attest, and the company must meet Norwegian wage requirements (minimallønn) controlled by Arbeidstilsynet. We ensure reporting and billing compliance and keep an eye on solidaransvar and documentation to reduce the risk of penalties.

P.S. Remember, every month without full control of your profitability is real money that you are irretrievably losing. Our 15-minute, free diagnosis costs nothing, and can be the beginning of recovering tens of thousands of crowns.
