The challenge

Freelancer hours were tracked through a patchwork of Excel files, handwritten notes and emails.

That produced a steady stream of errors, confusion and a heavy administrative load for the Lantis invoicing team.

Our approach

We built a custom web app where freelancers log their hours digitally in a few clicks. The tool handles different profiles and approval flows.

The invoicing team got one clear central overview, connected to Business Central and secured with Microsoft SSO. The solution went live in three months.

The result

Every timesheet is now processed centrally and without errors. The back-and-forth emailing is over, and payments are prepared faster and more accurately.

Everyone uses the app without friction, and it saves the admin team dozens of hours a week.

Thanks to this solution we now save hours and have more control. Thank you!

Jan de Bruin Project Manager, Lantis

At Lantis everything came down to clarity: who approves, what goes to invoicing, where the time goes. The team thought sharply about every flow. Timesheets now come in centrally and without errors, and the email traffic is a thing of the past. A pleasant, professional collaboration.
