We build the app with people who send their own invoices

Online Erhverv is a small Danish company. We make one app for trade businesses: quotes, calendar, crew app, hours, invoicing and bookkeeping in one place. It is used every day in a real construction company, and what does not work there does not make it in.

Built on a real building site

We saw skilled tradespeople spend their evenings at the kitchen table on quotes, timesheets and invoices, spread across three or four programs and a spreadsheet.

So we built one system for the whole business. Every week we fix and build based on what our users write to us. Many of the features exist because a tradesperson asked for them.

What we stand for

Four things we hold on to when we build.

Only tradesWe make software for tradespeople and no other industries. That is why the language, the jobs and the workflow fit the way you work.
Built together with tradespeopleThe features are shaped by owners and employees who use the app every day and write to us when something gets in the way.
A person on the phoneWhen you call, you talk to Lucass or Frederik, who know the system. Weekdays 8am-4pm (Danish time).
