Smart timesheets that save Lantis dozens of hours

10+ h

less admin per week

0

back-and-forth emails about hours

3 mo

from kickoff to live

01

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.

A member of the invoicing team overwhelmed at a desk covered in paper timesheets, with Excel on the screen

02

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.

03

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.

In their words

Dankzij deze oplossing besparen we nu uren tijd en hebben we meer controle, bedankt!

Jan De Bruyn Project Manager, Lantis

From Build More

At Lantis everything came down to clarity: who approves, what goes to invoicing, where the time sits. The team thought hard about every flow with us. Timesheets now come in centrally and error-free, and the emailing is over. A pleasant, professional collaboration.
