Reach every apartment in the buildings you supply

Short answer

Unitify for utilities connects water, district heating, gas and electricity suppliers to the apartment buildings they supply. Building managers run their HOAs, condominiums and owners' associations in Unitify, so residents submit meter readings in the app, see the supplier's bill next to the building's and pay by card. The supplier chooses the format: a module in its app, an API, its products in the manager's workspace, or our app.

In an apartment building the supplier sees an account number; the building's manager sees the people. Unitify is where managers run their buildings, so your meter readings, bills, payments and notices reach the right apartment through a channel residents already use.

Why does a supplier lose the resident at the building's door?

You bill each apartment, but you do not run the building. The reading period, the shutdown notice, the question about a bill and the late payment all pass through the building's manager, by phone, paper and chat. Unitify is the system where the manager runs them, so it can carry your data and your bill.

What does a utility get from Unitify?

Ten things in the supplier's own line of work. Each comes with what we would measure in a pilot. None of them is a promised result.

  1. 1

    Meter readings on time

    Residents submit readings in the app within the reading period you set for the building, with a push at the start of the period and another before it ends for those who have not sent a reading. Readings also arrive from Excel or CSV files, from staff and over the API, and each one records where it came from. You receive them over the API or as an Excel export.

    Measured in the pilot: apartments with a reading in the period, and readings that did not need a visit.

  2. 2

    Readings you can check before billing

    Before charges are calculated, an overview shows which readings were submitted, which were estimated by the average and which need a look. Residents are reminded of a verification date and of an expired verification. This is a reminder to the resident, not metrological control.

    Measured in the pilot: share of charges calculated by the average, and meters verified in time.

  3. 3

    Your bill next to the building's

    Unitify reads your charges for each personal account and shows them to the resident beside the building's own bill. You keep your billing system. A new export format from your billing system is connected on request, most in one to two days.

    Measured in the pilot: residents who added your account in the app.

  4. 4

    Online payment, money to your account

    The resident pays by card in the app through the acquiring of a bank or payment provider, under that provider's contract with you, and the money lands on your account. Unitify does not hold it. A payment rail is connected on request, most in one to two days.

    Measured in the pilot: share of your bills paid through the app.

  5. 5

    Your registry without manual matching

    The supplier cabinet is available today. You upload your registry as you already export it: xlsx, xls, csv or dbf. A layout we know is recognised automatically, and a new one is mapped once; then the fields are normalized and the bills are published to the right apartments. Bills of several suppliers are put together on one apartment.

    Measured in the pilot: share of registry rows matched to an apartment.

  6. 6

    Outage and maintenance notices to the right buildings

    A supplier sends outage and maintenance notices to the residents of the buildings it chooses. The notice goes out with a push message, and the reach is shown before sending: how many residents it will get to. Building managers already send such notices to their own buildings.

    Measured in the pilot: residents who received the notice, and calls on the day of a shutdown.

  7. 7

    Reminders to debtors, each with their own amount

    For charges kept in Unitify, a reminder goes to every debtor of a building with the amount that resident owes. It works for a supplier whose billing runs in Unitify.

    Measured in the pilot: collections in the pilot buildings against the rest.

  8. 8

    Fewer calls about bills

    The AI concierge answers residents from the data of their own apartment, in chat and on calls (telephony is set up per project): why a bill is what it is, when to submit a reading, whether a payment arrived. It takes readings and requests and hands the rest to a person. A person approves actions; every answer is logged.

    Measured in the pilot: share of questions about charges closed without an operator.

  9. 9

    Data by building

    A building plan shows debts and where the app is installed. The equipment register keeps a maintenance plan, and a ready checklist covers readiness for the heating season: metering nodes and the season's paperwork. Data on an apartment goes to a supplier only as law and contract allow, and personal data only with consent.

    Measured in the pilot: which of this data you use.

  10. 10

    Smart meters and AMR

    Smart meters, AMR systems and gateways that expose an interface, including Modbus or M-Bus gateways, are connected per project. Until then readings reach Unitify from residents in the app, from Excel or CSV files and over the API. All three work today.

    Measured in the pilot: share of readings that arrive remotely.

What does a resident see?

One list works in every building on Unitify. The other depends on the meter.

In every building on Unitify

  • Your bill next to the building's bill
  • Card payment in one app
  • A form for meter readings
  • The manager's news with push, including outage notices
  • A chat with the AI concierge about charges
  • A monthly report on the building

Where the meter allows

  • Readings from smart meters
  • Readings from AMR systems
  • Readings through Modbus or M-Bus gateways

How can a utility work with Unitify?

Four formats. You choose the format. The timeline follows it and your own security review: name the format, and we give you a date.

  1. 1

    A module inside your app or cabinet

    The bill, readings, payment, notices and the AI chat run inside your app as a mini-app, a deep link or a set of screens. Residents sign in with your ID, and the manager keeps working in Unitify. If your app already holds many customers, this is the strong option: they are already there.

  2. 2

    API and data flows

    Readings flow from Unitify to you over the API, webhooks or an Excel export. Your bills and registries flow to us over the API or as a file. The public API is GraphQL, with OpenID Connect sign-in.

  3. 3

    Your products in the manager's workspace

    The manager sees your bills for the buildings they run, reading deadlines, your notices, common meters and the heating season checklist. Everyone in the management company sees them, not only the accountant.

    How this works
  4. 4

    Our resident app

    If you do not have an app of your own, residents see your bill next to the building's in the Unitify app and pay there.

What does a management company see from its suppliers?

A management company works in a web workspace all day: the director, the building managers, the dispatcher, the technicians and the accountant. Your data shows up there, next to the buildings it belongs to. Everyone who works there sees it, and the manager does not have to chase paper.

The workspace is ready today; each of your products is connected to it one at a time, together with your team. Unitify does not hold residents' money.

What if a supplier still bills on paper or in Excel?

Then Unitify can be your billing, and it is wider than billing. The money is shown in three places, from the same data.

  1. 1

    Billing

    A list of accounts, resources (electricity, cold and hot water, heating, gas and sewerage), tariffs, meter readings and bills, with card payment in the resident app. You do not need an IT team of your own.

    Billing in Unitify
  2. 2

    Management reporting

    Income and spending for each building and for the supplier as a whole: what was billed, what was collected and what is owed.

  3. 3

    Reports to residents

    A monthly report in the resident app and on the building's page. A sample for a typical building is on the residents' page.

    See a sample monthly report

Can a resident pay all suppliers with one payment?

Where the local banks and payment rails allow it, yes: one bill for the apartment that collects the building's charges and the suppliers' charges, with the payment split between the recipients by the bank or the payment provider. It depends on the market and on what the partner banks support. We agree it per country, with you and the bank. Where it is not available, the resident sees each bill next to the others and pays each one by card. Unitify does not hold the money.

How does Unitify connect to a utility?

Who bills utilities in an apartment building?

Two verified examples. A supplier bills each apartment, and the building's manager is the one who reaches it every day.

Legal facts are taken word for word from the primary sources.

Who is behind Unitify, and what has it run?

Unitify's founder previously ran a residential management company serving 20,000 residents, then built a platform that reached 10,000 management companies and 5M+ apartments, then exited.

At Ande Tower in Batumi (about 500 apartments), collections rose from 40% to 80% of monthly charges over six months, and requests are handled three times faster. At Avant Park in Baku (1,000 apartments), the share of collected monthly payments made through the resident app grew from 19% in June 2026 to 74% in August 2026.

A developer in Nairobi sent spreadsheets with layouts and floor plans, and Unitify's AI built the building in the system, 15 entrances, 138 floors in total and 510 apartments, in seconds.

These are the figures of building managers, not of a supplier. A pilot reports yours.

About the founder

What does a pilot with a utility look like?

We start on live buildings you already supply, without exclusivity. Over a pilot of a few months we report the numbers you choose: apartments that submitted a reading in the period, readings that did not need a visit, residents who added your account in the app, and the share of your bills paid through it. You decide on the next step from your own data.

Frequently asked questions

What does a utility get from Unitify?

Meter readings on time, your bills in front of residents next to the building's, card payment, notices to the right buildings and answers to residents' questions. We measure each in a pilot on your data.

Do we have to replace our billing system?

No. Unitify reads your charges and registry in the form you already export and shows them to residents. A new export format from your billing system is connected on request, most in one to two days.

Can we upload our registry ourselves?

Yes. The supplier cabinet is available today: you upload the registry as you already export it (xlsx, xls, csv or dbf), a layout we know is recognised automatically and a new one is mapped once, then the fields are normalized, and the bills of several suppliers are put together on one apartment.

How do meter readings reach us?

Residents submit them in the app within the reading period, with reminders once a reading period is set for the building. They also come from files, from staff and over the API, each with its source. You receive them over the API or as an Excel export.

Can you connect smart meters?

Yes, per project, where the meter, AMR system or gateway exposes an interface, including Modbus or M-Bus gateways.

Does the money go through Unitify?

No. Residents pay through the acquiring of a bank or payment provider, and the money lands on the recipient's account. Unitify is software, not a payment institution.

Can residents pay all suppliers on one bill?

Where the local banks and payment rails allow it, yes: one bill for the apartment, with the payment split between the recipients by the bank or the payment provider. It depends on the market and on what the partner banks support. Where it is not available, the resident sees each bill next to the others and pays each one by card.

Does Unitify have its own resident app?

Yes. Unitify has its own resident app, and managers use it today. A supplier whose app already holds many customers can embed the same features in that app instead.

Can we send an outage notice only to the affected buildings?

Yes. You send an outage or maintenance notice to the residents of the buildings you choose, with a push message, and the reach is shown before sending.

Who answers residents' questions about our bills?

The AI concierge answers from the data of the resident's apartment, in chat and on calls, and hands the rest to a person. Every answer is logged.

We still bill on paper or in Excel. Can Unitify do the billing?

Yes. Unitify holds the list of accounts, the resources, the tariffs, the readings and the bills, with card payment in the resident app, and adds reporting for the supplier and a monthly report for residents.

How do residents sign in?

Through your customer ID over OpenID Connect, or in the Unitify app. The resident adds their account once.

Where is the data stored?

Kazakhstan and Uzbekistan run on local servers in the country, the EU on servers in Düsseldorf, Germany, and other markets are agreed per deployment. Your country or your own servers are available on request. More on the security page.

Is this exclusive?

No. A pilot starts on live buildings without exclusivity.

What does it cost?

Plans for building managers are on the pricing page. Integration formats are priced after a short brief.
