Custom job management for project-based SMBs

The challenge

Norwegian project-based SMBs — construction and installation firms, trade businesses, technical contractors — sit in a gap between tools that are too complex and tools that are too generic. Microsoft Project is built for large projects with dedicated planners, while Trello and Asana lack time tracking, billable-hour management and accounting integration.

Jobbkontroll AS is building the platform that fills that gap. Before WOLLUM came on board, no existing tool in the market covered all three of the following at once:

• Time tracking that actually works on a phone in the field — not a desktop site shrunk into mobile, but an interface designed for one thumb and patchy reception.
• Real-time financial visibility per project, so project leads can see billable rate without waiting for monthly reports.
• Seamless flow from time entry to invoice via Norwegian accounting systems — without manual export-imports that introduce errors and delay.

Approach

WOLLUM owns the full delivery: product strategy, design, frontend, backend and operations. That lets the Jobbkontroll team focus on go-to-market and customer dialogue while we handle product and technology.

Mobile-first from day 1

We designed the flows for the field worker first, not the office manager. The result is that the most important tasks — logging hours, checking job status, reporting issues — can be done one-thumbed in a stairwell or a construction lift.

A stack chosen to scale

Next.js on Vercel for web and admin, React Native for the mobile app, PostgreSQL for data. A modern stack with no experimental choices — it scales from pilot to many thousands of users without rewrites, and it is staffed by the Norwegian developer market when Jobbkontroll eventually grows the team.

Norwegian integrations as a premise

The integration strategy starts with the public APIs from Fiken, Tripletex and Visma. That means an hour logged in the field can land as an invoice line in the customer's accounting system without manual handling — and the Jobbkontroll customer never has to leave their existing accounting setup.

Outcome

The platform is in delivery and pilot-ready in 2026. The numbers below are pilot targets, not measured production figures — they will be updated once the pilot has run for a full month.

• Mobile-first time-entry flow: three taps from app open to a saved entry, including offline (queued for later sync).
• Real-time financial dashboard per project, with billable rate and budget variance as primary KPIs.
• Two-way integration with Norwegian accounting systems — hours out, invoices in — built on the published APIs.
• Source code and operations owned by Jobbkontroll AS. WOLLUM delivers as a partner, not as lock-in.
