Chapters
- Chapter 1 of 8 · Bills & AI
Photograph the bill. The rest happens.
Take a photo with the app or upload a PDF in the browser. ImmoAktas reads the sender, amount, period and cost type, and splits bills that run over the turn of the year across both years, to the day.
- Insurance 1 Oct to 30 Sep: €388.16 lands in 2025, €1,151.84 in 2026
- Every recognised field can be changed, the bill stays linked
- A checklist shows which bill is still missing for the year
- Chapter 2 of 8 · Properties & timelines
Everything has a date. Even the floor area.
Floor area, occupants, advance payments and tenants are timelines, not fixed values. If something changes on 1 July, ImmoAktas splits the year exactly there. You do not have to convert anything. Floors (attic, upper floors, ground floor, basement) can still be added or removed after you create the house.

- Baby on 15 September: 4 people from that day, 1,203 person days
- Vacancy is charged to you automatically, not to the tenant
- Chapter 3 of 8 · Tenancies & chronicle
Every flat tells its story.
The current agreement on top, all earlier ones below, with addenda, deposit and handover report. The chronicle answers every question of the kind “How did things stand on …?”.

- Corrections are logged, nothing is silently overwritten

- Chapter 5 of 8 · Statements
Every figure has a “Why?” button.
ImmoAktas produces the statement per flat with costs, advance payments and result. The calculation is visible to you and your tenant. That saves questions.
