Byggdagboken is the construction industry’s easiest digital project tool. Here you can gather timesheets, logbook, ÄTA, self-inspections, quotes, and invoicing in one system, directly on your mobile or tablet. With over 30,000 users, it’s an ERP system for the construction industry already used every day, out on real job sites and not just in the office.
Loose notes, texts, and Excel files are replaced by one shared tool the whole crew can access. The site manager gets an overview of time, costs, and status in every project. The tradesperson reports in seconds. The office doesn’t have to chase documentation. You spend less time on admin and more time building.
Byggdagboken follows the entire flow: estimating, quotes, work orders, ÄTA, invoicing, and ROT. Timesheets and Change Orders automatically become invoice documentation, and through integrations with, among others, Fortnox, Björn Lundén, and Hogia, you avoid duplicate work with your accounting and payroll system.
Byggdagboken was first in the industry with online purchase, so you can get started today. Free onboarding, training, and support are included in all packages, whether you’re two tradespeople or a larger contracting company.
We free up more time and create more value for our customers.
