In the picture, a high stone wall can be seen in the background. The stones are quite small and have been arranged four times, two next to each other and two below each other, in such a way that they have formed several ovals. In front of this wall in the centre of the picture is a small tree in a dark pot. To the left of the tree are two men in dark suits talking about istas heat-contracting. The jacket of the man on the left is open, revealing his white T-shirt, and he is holding a document in his hands in front of his upper body. The man on the right, standing with his back to the plant, is carrying a black cloth bag in his left hand.

Debicasso: Convenience and Time Savings in One!

As a property manager, your goal is to keep your residents happy. But in reality, there’s often much more to it: tenant changes, arranging individual energy billing, and handling all kinds of time-​consuming administrative tasks.

With Debicasso, we’re here to take that work off your hands. We manage the entire payment process for your residents’ billing — from collecting and calculating advance payments, to carrying out collections, paying the energy supplier, and preparing the final settlement for your residents. This means you save valuable time and have far fewer worries.

We fully comply with the Debt Collection Quality Act

We adhere fully with the requirements outlined in the Debt Collection Quality Act. Transparent and professional communication is central to our approach, and we respect the rights of both our clients and debtors. To ensure this, we are registered in the official debt collection register and strictly adhere to all legal guidelines. Our working method is designed not only to meet legal obligations but also to maintain and enhance the trust and satisfaction of our clients. The Wki establishes clear quality standards for debt collection activities, and we guarantee that our operations always align with these standards and regulations.

Debicasso: What we arrange for You

Discover the full suite of advantages that come with ista's services. Whether you are overseeing a single property or a portfolio of buildings, ista has the knowledge and know-how to help you increase efficiency while decreasing costs.

What happens if payments are not made?

If a payment is not received within the agreed payment term, we will send the resident a reminder, followed by a formal notice if necessary. At ista, we value a compassionate approach and personal contact.

Therefore, we like to reach out to the resident by phone to discuss possible solutions, such as arranging a payment plan. If the resident still does not pay, we will, in consultation with the manager, refer the case to a bailiff.

Insight via the ista Webportal

You gain access to your Debicasso properties through the ista Webportal, and upon logging in, you have immediate access to all activities and daily updated information. In addition to all settlements and financial matters, you can also view the status and details of ongoing cases, such as outstanding items, payment arrears, arrangements made, and possible bailiff cases. Everything is clear and well-organized. Together with our PlusPakket, the costs for relocations and repairs are covered, so you no longer receive separate invoices for these.

A personal Debicasso Portal for your residents!

Your residents have their access to their very own Debicasso portal.
Here they can find their settlement statements and advance payment invoices, and they can check the status of their payments.

From viewing settlement statements and advance payment invoices to tracking payment status — it’s all right at their fingertips.
Need to update an advance payment amount or bank account? No problem. Residents can make changes and grant direct debit authorization in just a few clicks.
With all energy billing information gathered in one easy-to-use portal, your residents stay informed, in control, and connected.

The buildings have balconies with dark railings, and some balconies are decorated with plants and furniture. A wide, paved footpath stretches between the buildings and continues into the distance. On the left side of the path are lush green areas and colourful flowerbeds that embellish the space between the buildings. On the right-hand side of the path, young trees are planted at regular intervals, forming a green avenue together with manicured lawns. Other buildings can be seen in the background, completing the urban surroundings of the residential complex. The sky is clear and blue, indicating a sunny day. Overall, the picture conveys a calm and pleasant living atmosphere in a modern, well-maintained environment.
