Automations & developments
Tailor-made for the client.
Where available software reaches its limits, we build our own: tailored to the client's processes.
Personalised DATEV export
Every booking lands automatically on the correct advita cost centre, neatly prepared for financial accounting. Verifiable for both sides via checksum and running without a single failure since the first run.
live since day 50
Digital tenancy agreement
Modelled on the client's letting process: property presentation, unit selection by type of use, graduated rent and documents per person. The on-site care team concludes contracts directly in digital form.

Reporting & dashboards
Occupancy, vacancy rate, move-ins and move-outs and cost centres updated daily in the portal, plus a movements dashboard. Fully replaces the manual analysis. Additional reports on request are delivered within a few hours, and have been from the start.
automated since month 3
One data foundation
Master data and accounting run in a closed loop. We checked all 13,000 rent charges of the first month before the first direct debit collection, and the data arrives in the client's financial accounting exactly as usual.

Voices
From the project.

Maximilian Werner
CTO
With regular operation, the real work was only just beginning. Since day one we have been developing further together with advita: from the digital tenancy agreement to individual reports. Every solution grows out of a real process on site.

“Our collaboration with advita was built on mutual trust from the very beginning. We wanted to repay that advance with results: with a takeover that went smoothly for the residents, and with a management service both sides can rely on every day.”

“After 25 years in operations, I know that in senior living, reliable processes and clear communication count more than anywhere else. Residents, relatives and on-site teams have to be able to rely on them. That was especially important to us from the very beginning.”
