OpenImmo Explained: Export Listings to ImmoScout24 & Immowelt
Key takeaways
- OpenImmo is the XML industry standard for exchanging data with property portals.
- Exporting from one data source replaces manual entry on every portal.
- Updates and deactivations run through the same path.
- Data quality decides how a listing performs on the portal.
- The biggest gain comes when export is part of a continuous process.
When you market a flat, you want it visible on as many portals as possible – without maintaining each listing separately. That's exactly what OpenImmo is for: an open standard that unifies data exchange between management software and property portals.
What is OpenImmo?
OpenImmo is an XML-based exchange format that has become the industry standard in German-speaking markets. It describes a property in a structured way: type, location, areas, prices, fit-out, texts and images. Because major portals like ImmobilienScout24 and Immowelt understand OpenImmo, listings can be handed over automatically from one software – instead of typing them into each portal by hand.
Why manual entry is expensive
Creating the same flat on three portals by hand means doing the work three times – and risking errors three times.
| Manual per portal | OpenImmo export | |
|---|---|---|
| Effort | repeated per portal | once, centrally |
| Consistency | error-prone | uniform |
| Updates | repeat everywhere | one path |
| Deactivation | easy to forget | automatic |
Typical consequences of the manual route: one portal shows the old rent, another the new one; a let flat accidentally stays online; and every change must be repeated everywhere. Exporting from a single data source removes this.
How export works in practice
The flow is simple:
- You maintain the property data and images once, centrally, in your software.
- The software generates an OpenImmo-compliant package from it.
- That package is handed over to the connected portals.
- Updates and deactivations run through the same path.
The result: a consistent presence across all channels, with minimal effort.
Data quality is the key
An export is only as good as the underlying data. Complete details on area, energy and fit-out, good images and a clean description decide how a listing performs on the portal. Keeping master data maintained per unit lets you market a vacant flat in minutes instead of hours – a direct lever against vacancy.
From listing to tenancy
The real advantage appears when export doesn't end at the portal but is part of a continuous process: enquiries from the portals flow back into the same platform, become prospects – and the chosen applicant becomes a tenant without duplicate data entry.
In Immo Manager, OpenImmo export is part of exactly this chain. For an overview of all capabilities, see our features page.
Frequently asked questions
What is OpenImmo?
An XML-based exchange format that has become the industry standard in German-speaking markets. It describes a property in a structured way: type, location, areas, prices, fit-out, texts and images.
Which portals support OpenImmo?
Major portals such as ImmobilienScout24 and Immowelt understand OpenImmo, as do many other platforms. This lets listings be handed over automatically from one piece of software.
What does export save compared to manual entry?
Time and errors: you maintain the unit once instead of several times, and all portals receive the same, current state. Inconsistent details and forgotten updates disappear.
What belongs in a good listing?
Complete details on area, energy and fit-out, good images and a clean description. An export is only as good as the underlying data.
How does export relate to letting?
At best, enquiries from the portals flow back into the same platform, become prospects – and the chosen applicant becomes a tenant without duplicate data entry.
