For Norwegian contractors and subcontractors

Norwegian construction runs on calls, texts, and spreadsheets.It doesn't have to.

Constratto replaces the back-and-forth with a structured platform for posting assignments, comparing bids, signing contracts, and tracking milestones — built for how jobs in Norway actually work.

Free for subcontractors. 30-day free trial for contractors. No credit card required.

Common questions

Do my subcontractors need to be on Constratto?
Yes — but it's free for them and takes about two minutes to set up. Subcontractors actively browse open assignments, so many are already looking for the kind of work you're posting.
We already use project management software. Do we need another tool?
Most project management tools start after the contract is signed. Constratto handles what comes before: sourcing subcontractors, comparing bids, and generating a signed contract. Many teams use both.
Is this suitable for a sole trader or very small company?
Yes. Constratto works for a one-person operation as well as larger teams. You only need an active Norwegian org.nr. to register.
Who can see the documents I upload?
Only the parties on the contract can access its documents — the contractor who posted the assignment and the subcontractor whose bid was accepted. No other users, companies, or Constratto staff can view your files.
Are the contracts generated by Constratto legally binding in Norway?
Yes. Contracts are signed digitally by both parties and timestamped. They reference the agreed scope, price, and milestones, making them enforceable under Norwegian contract law (avtaleloven). We recommend involving a lawyer for high-value engagements, but the contract structure covers the fundamentals.
What file types can I upload to the document vault?
PDF, Word (.docx), Excel (.xlsx), images (PNG, JPG), and CAD exports are all supported. Each file is versioned so you can track changes over time and always access previous revisions.
What happens to my documents if I cancel my subscription?
Your data is yours. You have 30 days after cancellation to export all contracts, documents, and project history as a ZIP archive. After that, data is deleted from our servers in accordance with our retention policy.
Can subcontractors see each other's bids?
No. Bids are sealed — only the contractor who posted the assignment can view incoming bids. Subcontractors never see competitor pricing or terms.
How does milestone sign-off work?
The subcontractor marks a milestone complete and optionally attaches photos or delivery notes. The contractor receives a notification and approves or requests changes with one click. Every action is timestamped and stored on the contract record, giving both sides a clear audit trail.
Is Constratto free for subcontractors?
Yes. Subcontractors can browse assignments, submit bids, and manage contracts at no cost. Contractors pay a subscription to post assignments and access advanced project management features.
