My first six months monitoring rent arrears – what I’d change

Renting out flats in Poland is no longer a niche – more and more people are managing several units at once. And that’s where the trouble starts. Because the more units you have, the more deadlines to keep track of, and the more chances something will go wrong. Rent arrears can eat into your yield faster than you’d think. Over the past six months I tested a receivables monitoring system myself and went through quite the survival course. Some things worked from day one, others had to be fixed yesterday. Below – concrete takeaways from six months, no fluff. What shortened my response time, what turned out to be a dud, and what not to repeat.

The starting point – what arrears management looked like before the system

Spreadsheets. Manually checking the bank account. Tapping in deadlines from memory. That’s how it looked. The lack of automatic reminders meant I’d find out about a late payment days – sometimes weeks – after the fact. Every new unit in the portfolio added more deadlines to remember and deepened the mess. The history of conversations with tenants? Scattered across email, WhatsApp and a few notes on my phone. Reconstructing who promised what to whom – mission impossible.

Utility billing and operating costs were a separate problem. With room-by-room rentals, shortening the billing periods isn’t always an option – especially water, sewage and heating. Many landlords (I did this myself) use monthly flat-rates or settle usage by meter readings. Discrepancies in the calculations generated disputes, and disputes delayed payment of the base rent. A vicious circle.

Typical headaches? Missed deadlines, no record of contact with the tenant, reacting only once the debt had grown really serious. Every situation handled ad hoc, without any repeatable scheme. Firefighting instead of managing.

• The tenant regularly asks to push the payment date back by a few days
• Payments cover only part of the rent due, with no explanation
• No reply to messages about settlements for more than a week
• Sudden questioning of the operating charges or utility advance payments
• Avoiding in-person and phone contact once the payment deadline has passed
• Recurring delays in settling amounts due in consecutive months

What worked in the first six months

Automatic notifications. That was a game changer. The system sent a reminder three days before the due date, and if the money didn’t come in – further messages at set intervals. I didn’t have to check my account every day and manually compare incoming payments against the schedule. Interestingly, tenants liked it too. A few openly admitted the automation saved them from accidentally missing a deadline. Well, there you go.

Everything in one place – tenant data, agreements, current balances. No more digging through five sources at once. I open the unit’s panel and see the full payment history, a scan of the agreement, a record of the correspondence. In disputed situations that’s a huge difference – you’re not hunting for an email from three months ago, you’ve got everything at your fingertips.

Generating documents from within the system – payment demands, interest notes, balance confirmations – took more off my plate than I expected. SaaS solutions on the Polish market already have this in their basic packages, from 9.84 PLN per unit per month. But the real change? The average response time to a late payment dropped from weeks to a few days. And that did the job. The sooner I got in touch after a missed deadline, the better the chance of a quick payment without escalation. Simple, but I had to see it in numbers to really believe it.

Three areas that needed immediate correction

First mistake – too soft an approach. I assumed a polite reminder would suffice and that a formal demand was a last resort. Naive. The data from the first six months revealed the brutal truth – the recovery rate on amounts due drops dramatically after 30 days past the due date. Every week of delay worsened the chances of an amicable settlement and increased the risk it would end up with a lawyer. Lesson learned.

Second problem – no integration with KSeF and automatic utility billing. Issuing documents manually and re-keying data between systems ate up time I could have spent on normal work with tenants. In 2026, when the National e-Invoicing System (KSeF) is already standard, skipping this integration generates accounting errors and delays in your documentation. A silly mistake on my part not to have sorted it out straight away.

The third matter – tenant vetting. Or rather the lack of it. A chat and a “general impression” are no substitute for systematic screening. I found that out the hard way. Industry sources say it plainly: require proof of income, set a deposit higher than one month’s rent, and get a guarantee from a third party. These things genuinely reduce the risk of payment problems.

Tip: It’s worth launching the reminder procedure no later than the fifth business day after the deadline passes. First contact – a polite phone call or text, to find out what’s going on. A formal payment demand should reach the tenant no later than 14 days after the due date. Such a scheme lets you preserve a good relationship with someone who simply forgot about the transfer (it happens), while at the same time disciplining those who tend to drag things out.

The cost of rent arrears vs rental profitability

The yield on long-term rentals in big Polish cities is 5-7% a year. A decent result, sure. But just one quarter with no income from a flat at 3000 PLN a month and you lose 9000 PLN. Over the year your yield drops by nearly half. And the fixed costs keep rolling – the administrative service charge, the renovation fund, utility advance payments. Those bills don’t wait for the tenant.

Investment calculations need to factor in fixed operating costs. Managing a property isn’t limited to collecting the rent. You have to pay the administrative service charge, cover utilities, water and electricity usage. The way settlements are handled depends on the provisions of the agreement. These costs can be passed on to the tenant in full or in part. The investor needs to know the exact amount of these charges in order to correctly calculate the yield.

The real losses aren’t only the lost rent. On top come the time spent on correspondence, preparing demands, compiling documentation. If the matter escalates – lawyer’s fees, court costs, the bailiff. And then there’s the opportunity cost. Those hours spent chasing arrears I could have devoted to growing the portfolio or negotiating better terms. There’s no kidding ourselves – arrears cost a lot more than meets the eye.

I tested both approaches in practice. The reactive one – you wait for the problem to blow up, then put out the fire – generates higher costs and delivers worse results. The proactive one – solid tenant vetting, automatic monitoring, a quick response – lets you limit the losses before they start threatening the profitability of the investment. Systematic receivables management isn’t a whim. It’s a condition for maintaining your target yield. Full stop.

Tools and processes worth implementing from day one

The foundation is a SaaS system with automatic payment monitoring, document generation and KSeF integration. There are plenty of options on the Polish market – utility billing, remote signing of agreements, creating invoices, addenda and protocols from within the platform. The per-unit pricing model means even an owner of one or two flats can use it without straining the budget. I tested a few and I’d recommend starting with a free trial before you commit.

The handover protocol with photographic documentation. Underrated, yet it makes a difference. It protects against disputes at the end of a tenancy, but it also works psychologically – a tenant who knows the condition of the unit is documented down to the centimetre takes settling their obligations more seriously. Solid initial documentation also makes it easier to pursue claims when the damage goes beyond normal wear and tear.

Article 675 § 1 of the Civil Code provides that, after the tenancy agreement ends, the tenant is obliged to return the item in an undeteriorated condition; however, they are not liable for wear and tear resulting from proper use.

Tenant screening – verifying income, rental history, references from previous landlords. Don’t skip this step, seriously. And as for the agreement – an occasional lease with a notarised declaration of voluntary submission to enforcement is the strongest safeguard you have. This arrangement eases the restrictions arising from the Tenants’ Rights Protection Act and speeds up the procedure for recovering the unit in cases of persistent arrears or a refusal to move out after the agreement expires. I use it myself and can’t imagine doing it any other way.

Frequently asked questions

How quickly should you react to a first late rent payment?

At most five business days after the deadline passes – after that it only gets worse. Start with a polite phone call or text. No reproach, just establish what happened. If the money doesn’t come in over the next seven days – a formal payment demand with a set deadline. The sooner you react, the smaller the chance the matter ends up in debt collection. Most delays are plain forgetfulness and one phone call sorts it out.

Is an arrears monitoring system worth it when managing 1-3 units?

Do the maths yourself. Basic SaaS packages start at 9.84 PLN per unit per month. Three flats – about 30 PLN. The price of a coffee and a cake. That amount pays for itself by avoiding a single case of dragged-out arrears a year. Automatic reminders, all your data in one place, ready-made documents – that’s a saving of several hours a month. It’s especially worth it when you combine managing units with a full-time job or another business. You don’t have the headspace then to handle everything manually.

Which documents should you prepare before sending a payment demand?

A specific list: a copy of the tenancy agreement with the provisions on payment dates and rent amount, a payment history confirming the arrears, and documentation of the correspondence with the tenant so far. The demand itself should state the exact amount of the debt broken down by individual months, the payment deadline and a note about the consequences of continuing to dodge payment. Send it by registered mail with acknowledgement of receipt – that’s your proof of delivery should the matter go to court. Don’t skip this step, even if it seems excessive.

Summary

Six months with an arrears monitoring system taught me three things. First – automation (reminders, documents, centralised data) eliminates human error and drastically shortens response time. Second – early intervention, within the first days after the deadline, delivers results many times better than waiting a month. Third – solid prevention, meaning thorough tenant screening and a well-drafted agreement, heads off problems before they even appear.

The biggest mistake landlords make? Putting off implementing systematic monitoring “for later”. Every month without an organised process is a risk of missing a growing arrears balance, losing documentation and seeing your yield slip. The cost of having no system – lost rent, legal expenses, wasted time – far exceeds the price of even the most comprehensive tools on the market. Tried and tested.

The market offers packages with two months of free access for portfolios of up to 30 units. Two months – enough to test the automatic notifications, check the integration with your existing settlement process and see whether tenants start paying on time. Better to do it now than wait until the next arrears force you to act in emergency mode. Because by then it’s already too late for calm planning.
