Letting one or more properties? The biggest cost is not the tool — it is the indexation you forget. One year of not indexing €800 rent at ± 3% inflation is about €290 you will never get back (max. 3 months retroactive).

Questions about Pro
How does the annual reminder work?
You add your property or properties once to your account. About a month before every indexation anniversary, we email you the exact new rent with a link to the ready-made letter — in time to meet the legal deadline.
How do I pay?
Securely via Stripe (Bancontact, credit card). You receive a payment confirmation immediately; logging in happens via an email link, without a password.
Can I cancel?
Yes, at any time before the annual renewal — one email is enough. You keep access until the end of the paid period.
