How the reminder system works

Rent follow-ups are the tail end of the payment flow: same states, same data.

1

Daily check across every apartment

Every morning the system reviews rents, pending confirmations, contracts and deadlines for all your apartments.

2

The right channel for each tenant

Tenants with the app get a push notification. Tenants without it get the same message on WhatsApp, using just a phone number.

3

Only what needs a decision

Confirmations, alerts and expiring deadlines reach you. Routine reminders go straight to tenants without involving you.

The life of an unpaid rent

A missed rent payment follows a fixed schedule, from due date to confirmation.

1st

Due date

The rent is due. The tenant already received the month’s rent notice on the 1st.

5th

First reminder

The unpaid rent turns late and the tenant receives the first automatic reminder.

10th

Second reminder + your alert

A second reminder goes to the tenant, and you are alerted that the rent is still unpaid.

Payment and confirmation

The tenant marks the rent as paid and attaches proof. If you don’t confirm within 7 days, the system reminds you.

What the system tracks

🔔

Rent follow-ups

Unpaid rent turns late on day 5 with a first reminder to the tenant; a second reminder and an alert to you follow on day 10.

👆

One-tap manual reminder

Send a reminder at any time with a standard message: “if you already paid, ignore this.”

💬

WhatsApp for tenants without the app

A phone number is enough. These tenants get the new month’s rent notice and late reminders on WhatsApp, and can opt out themselves.

📄

Contract deadline warnings

A warning fires 30 days before the contract end date, and a second, high-priority warning fires 7 days before.

Custom deadlines

Set your own advance notice per deadline, with a default of 30 days; a final warning always fires 7 days out.

Reminders for you

A payment marked by the tenant and awaiting your confirmation for more than 7 days is brought back to your attention.

Where deadlines come from

📄

Contract-generated deadlines

Renewal and registration deadlines are created automatically when the contract is created, with the reminder already set.

🔁

Custom and recurring deadlines

Add deadlines for registrations, maintenance or tax dates. Set them to repeat monthly, quarterly or yearly, so an annual boiler service returns on its own.

🗓️

One calendar per apartment

Every deadline for an apartment appears in a single calendar with days remaining. Completed deadlines are archived.

Who gets notified, and when

Every reminder starts from a concrete event — a due date, a late payment, a share assigned — never a broadcast.

Event Who When
Rent turns late Tenant Day 5 and day 10 after the due date
Rent still unpaid You Day 10 after the due date
New month’s rent Tenant without the app On the 1st, via WhatsApp
Payment awaiting confirmation You After 7 days unconfirmed
Contract expiring You 30 and 7 days before the end date
Custom deadline You Your chosen notice, and 7 days before
FAQ

Questions about reminders

Do I write the reminder messages?
No. Messages use a standard, factual format. The manual reminder includes “if you already paid, ignore this.”
Do tenants without the app get reminders?
Yes, on WhatsApp, using their phone number. No app installation is required on their side.
Can I choose how far in advance I’m warned?
Yes, for custom deadlines. Set the advance notice per deadline; the default is 30 days, and a final warning always fires 7 days out.
Do reminders cover bill shares too?
Bill shares notify tenants when a split is assigned. Scheduled day-5 and day-10 follow-ups apply to rent.
Do I get alerted, or only tenants?
Both, depending on the event. You’re alerted for persistent late rent, unconfirmed payments, and expiring contracts or deadlines.
Can tenants feel spammed?
Reminders fire only on concrete events, never as a broadcast. Tenants can opt out of WhatsApp messages themselves.
