Why Werkbriefje.app Connect with Yuki?

Yuki is different from most accounting packages. It was created based on the idea that the entrepreneur provides the data and the accountant processes it. Many construction companies did not choose Yuki themselves, but rather ended up using it through their accounting firm. And that works, as long as the data submission process runs smoothly.

That is precisely where the problem lies. Many small construction companies submit their hours and materials via Excel files, photos of paper timesheets, or sometimes even WhatsApp messages. The accountant has to process all of this manually in Yuki, and that takes time, that costs money, and occasionally causes a hassle at the end of the year. With the Werkbriefje.app With the Yuki integration, everything is automatically ready in Yuki, in the way your accountant prefers.
