Property management platform: how to choose
Do you have two flats in different cities, rent in one spreadsheet, meter readings in another and leases buried in your email? A good property management platform puts all of this in one place, but only if it fits the way you actually rent. Instead of a list of products, you get a list of criteria here: what to check for each one, what to ask the vendor and where it is easiest to go wrong.
What a property management platform should do
A platform should take repetitive work off your plate: tracking deadlines, calculating what is due, looking for documents and answering the same tenant questions over and over. Everything that happens with a unit should be visible in one place, not stored in the owner’s memory.
In practice this means several areas that are worth assessing separately. A platform can be great at generating leases and weak at handling utilities, or have no way to contact the tenant at all. So before you compare prices, decide which areas are a must for you and which are just nice to have.
- Rent and utility billing - calculating charges, meter readings, splitting costs between tenants.
- Payment reminders - automatic notifications before the due date and a view of overdue payments.
- Leases and documents - templates, lease dates, an archive of annexes and handover reports.
- Tenant communication - a tenant portal, maintenance requests, contact history.
- Invoices, KSeF and accounting - whether you issue invoices in the platform or separately, and how data reaches your accountant.
- Data security - where tenant data is stored and who has access to it.
- Cost for your portfolio - how much you will pay for your current number of units and after adding more.
Selection criteria in one table
The table below is a cheat sheet for your call with a vendor offering a property management platform, or for the first day of a trial. We go through each row in more detail later in the article.
| Criterion | What to check | Question for the vendor |
|---|---|---|
| Utility billing | Flat fee or meter readings, splitting costs by room | How do I bill utilities in a flat rented out room by room? |
| Payment reminders | Notification channel, timing, overdue view | When and how does the tenant get a rent reminder? |
| Leases and documents | Templates, dates, archive, occasional lease | Does the system warn me about leases that are ending? |
| Tenant communication | Tenant portal, maintenance requests, contact history | What does the tenant see after logging in, and do they need to install anything? |
| KSeF and accounting | Issuing invoices, exporting data for the accountant | Do you handle invoices and KSeF, or do I do them separately? How do I export data for my accounting office? |
| Data security | Where data is stored, data processing agreement, roles | Will you sign a data processing agreement? |
| Cost | Pricing model, unit and user limits, extra charges | How much will I pay after adding another unit or a collaborator? |
Rent and utility billing: flat fee or meters
Check whether the platform bills utilities the same way your lease with the tenant does. Some systems only handle a fixed amount added to the rent, while others let you enter water, electricity, gas and heating readings and calculate the charge for you.
The difference shows most clearly when you rent by the room. When costs are split between several tenants, working out shares by hand in a spreadsheet is a quick way to end up in an argument over a few złoty that sours the relationship for the whole year. If the system calculates shares, check whether it shows each tenant their part and keeps a history of readings. If it doesn’t, keep the settlement in a spreadsheet and record readings in protocols you can go back to for the annual settlement.
Also pay attention to advance payments and adjustments. If you collect an advance for utilities and once a year settle it against actual usage, ask whether the platform will show the overpayment or shortfall, or whether that settlement stays in a spreadsheet.
Question for the vendor: “I have a flat rented out as three rooms with one shared electricity meter. Show me how I would bill one month in your system.” A specific case from your own portfolio will tell you more than a general feature list.
Payment reminders and tracking overdue rent
An automatic reminder before rent is due is the feature that pays back the setup time fastest. Instead of writing to each tenant separately, you set a rule once and the system sends the message for you.
Check three things: which channel the notification uses (email, SMS, a message in the tenant portal), whether you can set when it goes out, and whether after the due date you immediately see a list of overdue payments with amounts. A reminder without a view of who has paid and who has not solves only half the problem. You will find more on how to set up rent payment reminders and what tone to use in a separate guide.
For example, in Tenanto the rent has a set due date, and before it the system sends the tenant an automatic email reminder. That should be the minimum in any tool you are considering.
Question for the vendor: “Can I change the wording of the reminder, and does the tenant see the amount and the bank account number in it?” A message without these details prompts more questions instead of a bank transfer.
Leases, documents and occasional leases
The platform should know at least as much about each lease as you do: the number, the parties, the term, the amount and the status. That way it can warn you about a lease that is ending before the tenant asks about an extension or before you are left with an empty unit.
The second element is the document library. Leases, annexes, handover reports and invoices should be linked to a specific unit and tenant, not sit in one folder with names like “scan_new_2”. In a dispute, a handover report with photos of the flat’s condition that you can find in a minute is worth more than the best template.
If you sign occasional leases (najem okazjonalny), ask about this type separately. It requires a full set of attachments: the tenant’s notarised statement submitting to enforcement, an indication of the place the tenant will move to, and the consent of that property’s owner. On top of that, the lease must be reported to the tax office within the statutory deadline. A platform that reminds you of these steps, or at least lets you keep all attachments with the lease, lowers the risk that one missing document costs you the protection this type of lease gives.
When it comes to documents, also remember the energy performance certificate. When you rent out a unit, you give the tenant a copy, and the certificate is valid for a limited time. A reminder to renew it is a small thing that is easy to miss without a system.
Question for the vendor: “Will the system remind me about a lease that is ending, and how far in advance? Can I add my own lease template instead of yours?”
Tenant communication and maintenance requests
The tenant portal is where tenants check how much they owe, download documents and report faults on their own. A portal that works well cuts down on calls and emails, because the simplest matters get handled without you.
When assessing the portal, log in as a tenant, not as the owner. Check whether it works on a phone, whether the tenant has to install an app, and whether they understand what they see without instructions. If tenants do not start using the portal, you will be back to text messages and photos sent over messaging apps.
Maintenance requests are a separate module worth seeing in action. What matters is whether a request has a status (new, in progress, closed), whether you can assign a contractor and whether a year later you can find the repair history of a specific unit. A convenient setup is a kanban board with request statuses, plus a history of repairs and inspections stored in the building and unit records, not in a separate notebook.
Question for the vendor: “Can the tenant attach a photo to a request, and do they get a notification when its status changes?”
KSeF, invoices and working with your accountant
If you issue invoices for rent, check whether the platform supports the National e-Invoicing System (KSeF) at all, or whether you will issue invoices separately. Whether KSeF applies to you at all depends on how you settle tax on your rental income, so start with that question and only then assess the integration.
We described the rules and typical landlord situations in our article on rent invoices and the National e-Invoicing System. When choosing a tool, ask whether the invoice goes to KSeF directly from the platform or whether you have to move it to another program by hand. Not every rental tool issues invoices, and that doesn’t rule it out: you can issue the invoice in invoicing software, through your accountant or in the free KSeF Taxpayer Application, as long as you can easily export income data from the platform.
Corrections and the archive are a separate matter. Ask how a corrective invoice is issued, where documents are stored and whether your accountant will get the data in a format their software accepts. The simplest test: ask your accountant for a list of what they need every month and check whether the platform can export it.
If you pay tax on private rental income under the flat-rate system (ryczałt), the platform also helps you track income during the year. Under the act on flat-rate income tax, income from private rental is taxed at 8.5% up to PLN 100,000 a year, and anything above that at 12.5%. An income report broken down by month shows when you are getting close to the threshold.
Question for the vendor: “Do I issue invoices in your system, and if so, how do they get to KSeF and what happens when KSeF is unavailable?”
Tenant data security
When you enter tenant data into a property management platform, you hand the vendor personal data that you are responsible for as the landlord. That is why security is a criterion to check before you import your first tenant, not after.
Ask where the data is physically stored, whether the vendor will sign a data processing agreement and how backups work. Also check whether you can export your data and delete your account at any time. A platform you cannot leave with your own data ties you in more tightly than any subscription contract.
If you work with someone else, such as a property manager or a family member, see whether you can give them a separate account. Sharing one login and password is a risk, and you lose track of who changed what.
Question for the vendor: “Which country are your servers in, how often do you make backups, and in what format will you give me my data if I cancel?”
Reports and a view of your whole portfolio
Reports should answer the questions you ask yourself every month: how much came in, who is behind on payments, which units are empty and which leases end soon. If you have to export data and build a pivot table to get these answers, the reports are not doing their job.
Check whether you can download a report in a format you can open yourself or send to your accountant, for example PDF or a spreadsheet. With several units, a summary view also matters: the status of each flat, the current tenant and the time left on the lease on one screen. This view is usually what replaces the spreadsheet most owners started with.
Question for the vendor: “Show me an income and arrears report for last month for a sample portfolio. Can I download it as a file?”
Cost for a small portfolio and as it grows
Compare the cost for your current number of units and for the number you plan to have in two or three years. A property management platform that is cheap for one flat can get expensive quickly with several, and the other way round.
You will come across three basic models on the market: a fee per unit, a fixed subscription with a unit limit, and a free plan for the smallest portfolios. With a per-unit fee, the cost grows in step with your portfolio. A subscription with a limit can work out better when you are close to the plan’s upper limit, but once you go over it, the price jump can be significant.
Calculate the full cost, not just the price list amount. Add fees for extra users, modules sold separately, report exports and integrations. Also check whether prices are shown net or gross, because with private rental without VAT you will pay the gross amount. For example, the Tenanto plan pricing lists net prices with the gross equivalent, includes a free plan for one unit, and in higher plans varies the unit limit, the number of users and the range of reports.
Question for the vendor: “How much will I pay per month if in a year I have twice as many units and one collaborator with their own account?”
How to test a platform before you decide
The most reliable test a property management platform can go through is moving one real unit into it and running it for a full month. A sales demo shows the system’s best side, and your own unit will show the weaker ones.
- Pick the unit that takes the most work, for example a flat rented by the room.
- Enter the building, the unit, the tenant and the current lease with its dates.
- Set up the rent, utilities and a payment reminder, then check what the tenant actually received.
- Ask the tenant to log in to the portal and report a minor fault.
- Generate a report for the month and send it to your accountant, asking if it is enough.
- Try exporting all your data before you commit to a paid plan.
If after that month you know where to find every piece of information and the tenant did not call to ask how to pay, the tool has passed the test. If you kept going back to the spreadsheet every week, keep looking.
Frequently asked questions
Is a property management platform worth it for one flat?
Yes, although the benefit is mostly organisational. The platform keeps documents in order, reminds you of deadlines and stores your contact history with the tenant in one place. It proves most valuable in a dispute, when you can find the handover report and correspondence right away. With one unit, look for a free or low-cost plan, and switch to a paid one when you add another flat.
Can I move my data over from a spreadsheet?
It depends on the vendor, so ask about importing before you buy. With a few units, entering the data by hand usually takes less time than preparing an import file. With a larger portfolio, importing from a file saves hours, but check which fields it brings over and which you have to fill in by hand.
Does the tenant have to create an account on the platform?
Not always, but without an account they cannot use the tenant portal. Email reminders often reach people who never log in as well. If you want tenants to report faults and download documents themselves, check what the invitation and first login look like from their side.
What should I watch out for when switching platforms mid-tenancy?
Historical data matters most: payments, meter readings, maintenance requests and documents. Before you cancel the old tool, export everything and check that the files open. Tell your tenants about the change well in advance and give them the new way to get in touch and to pay.
One last piece of advice: before you choose a property management platform, write down the three things that take up most of your time as a landlord today, and test every vendor on exactly those. A tool that solves your three problems is a better choice than the one with the longest feature list.
