I'm building a SaaS product for construction companies and wanted to share the journey. The product is bygglog.se — a digital construction diary (byggdagbok) for Swedish contractors.
The Problem
In Sweden, construction companies are required to keep project logs. Most still use paper or Excel spreadsheets. This creates problems:
- Logs get lost or damaged on job sites
- Hard to search past entries
- No photo documentation linked to entries
- Difficult to share with clients or inspectors
The Solution
ByggLog is a web-based construction project logger where firms can:
- Create daily logs with photos and notes
- Track project timelines and milestones
- Generate reports for clients and authorities
- Manage multiple projects from one dashboard
Tech Stack
- Frontend: React with responsive design (works on phones at job sites)
- Backend: Node.js API
- Payments: Polar.sh for subscription management
- Hosting: Railway for the backend
Building in Public Stats
After a few months:
- 36 registered firms (27 external)
- 43 total users
- 0 paying customers (still in growth phase)
Honest numbers. The product works and people sign up, but converting free users to paid is the real challenge.
What I've Learned So Far
1. Construction workers aren't early adopters
They need to see the value immediately. A fancy UI means nothing — it has to be faster than their current process.
2. Mobile-first is mandatory
Most logging happens on-site from a phone, often with dirty hands and bad lighting. Big buttons, simple forms.
3. Swedish market nuances matter
Swedish construction regulations have specific requirements for project documentation. Generic project management tools don't cut it.
Pricing Model
We went with:
- Project owner: Free (30-day trial)
- Employee accounts: 200 SEK/month
Keeping the barrier low for project owners to get started, then monetizing through team usage.
Next Steps
- Gather feedback from registered firms
- Improve onboarding flow
- Add inspection checklist templates
If you're building B2B SaaS for traditional industries, I'd love to exchange experiences. Check out the product at bygglog.se.
