The challenge

A game without rules — who wins?

No one. Clients, project managers, contractors and designers need the same rules for everyone to reach the finish line. Bonsli is the rulebook that takes the vision to precision.

Almost three in four building projects go over budget.Source: Flyvbjerg et al., Project Management Journal (2026) — 186 building projects from a database of 11,011 projects.
Defects, errors and damage in the Swedish construction sector cost between SEK 59 and 111 billion a year.Source: Boverket, Kartläggning av fel, brister och skador inom byggsektorn (2018).
In 2024, 2,032 Swedish construction companies went bankrupt — almost forty a week.Source: Tillväxtanalys, Konkurser och offentliga ackord 2024.
Trade and craft services are the market where Swedish consumers lose the most money — SEK 4 billion a year.Source: Konsumentverket, Konsumentskadan i Sverige (2024).

It is rarely down to poor craftsmanship. It is down to no one seeing the same thing at the same time.

One vision. Two paths. Different outcomes.

From vision to precision

One goal. Four teams. One playing field.

Bonsli is the playing field.

Scattered→Unified

Unclear→Traceable

Unpredictable→Predictable

Same goal, same rules, same playing field.

No one has to carry the whole project in their head anymore.

How it works

One project. Six steps. One platform.

Every document in place and reviewed before the next step.

Every bid on the same terms.

Plans, meetings and decisions in one single thread.

Every payment is checked against the contract and the build — before it is made.

The final inspection becomes a reconciliation, not an investigation.

The home's costs and documents stay with it, for good.

Unified. Traceable. Predictable.

Who it's for

Everyone sees their part.

Where do we stand?

ClientIs the budget holding?

Project managementWhat's waiting for a decision?

ContractorWhen do I get paid?

DesignWhich revision applies?

In Bonsli, the same platform answers all four, at the same moment.

We'll show you Bonsli in your project.

It takes 30 minutes.

Bring your vision – we'll show you how to reach precision.
