Why the record matters more than the reminder
Most rent disputes are not about money a tenant refuses to pay. They are about money nobody can prove was paid: a transfer with no narration, cash handed to a caretaker, a part payment that one side remembers differently. Without a receipt and a running balance, it becomes your word against theirs.
Three habits prevent most of it. Give a numbered receipt for every payment, including part payments. Keep one balance per unit for the current rent year. Send each tenant a statement before renewal, so the conversation about what is owed happens before the rent year ends, not after.
If it does reach the point of notices and court, the same records are your evidence: the tenancy agreement, the amount due, each payment with its receipt number, and the balance.
Questions landlords ask
How do I keep proper records of rent payments?
Log every payment on the day it arrives, including part payments, give the tenant a numbered receipt, and keep one running balance per unit for the current rent year. When a tenant disputes what they owe, a statement listing each payment and receipt number usually settles it.
Can I use it for estate service charge?
Yes. Each unit has columns for rent, service charge and other charges, and each payment says what it was for. An estate that only collects service charge can leave the rent column at zero.
Will it remind me when rent is due?
The Tenants sheet shows the days left in each rent year and flags 'Renew soon' 90 days before the end, so you can start the renewal conversation early. It does not send messages; a property system can send reminders on its own.
Does it work on a phone?
Yes. It uses formulas that work the same in Excel, Google Sheets and LibreOffice. Upload it to Google Drive to log payments from a phone, and save the statement or receipt as PDF to send on WhatsApp.
What should I do if a tenant still refuses to pay?
Do not lock them out or remove the roof; self-help eviction can cost you damages. Serve the correct notices and go through the court, with your statement of account and receipts as evidence. Speak to a lawyer about the notice periods in your state.

Let tenants see their own statement
FASS builds property systems with rent and service-charge records, numbered receipts, statements tenants and residents can open themselves, reminders before renewal, and repair requests in one place. Each one is quoted after we understand how your properties are run.
