What immo-portal-services does

immo-portal-services GmbH, operating under the brand name immo-office, is a Hamburg-based vertical SaaS provider founded in 2009 (with the immo-office brand dating to 2007) that digitizes operational processes for the German residential property management industry (Wohnungswirtschaft). The company's modular platform consists of five core modules — Instandhaltung (maintenance management), Verkehrssicherung (digital inspection of safety obligations), Mieterwechsel (digital tenant changeover), Kundenmanagement (tenant ticketing), and Rechnungseingang (paperless invoice processing) — plus a Handwerkerportal add-on for external tradespeople. The platform is built as a web-based, cloud-ready application with native iOS/Android mobile apps that support offline field operations with later synchronization, and integrates via standardized APIs and index files into all major German housing-industry ERP systems, notably Aareon and WOWIPORT.

The platform addresses structural coordination problems in residential property management by eliminating paper-based inspections, manual invoice routing, fragmented tradesperson communication, and opaque tenant changeover workflows. Underlying technical components include digital signature handling, photo documentation with attachment to records, automated scheduling of up to 2,000 inspection obligations per property, automated invoice content recognition with configurable cost-allocation (Kontierung) workflows, and a bidirectional ticket-to-work-order linkage across modules. Documented ERP integration partnerships (Aareon, Dr. Klein Wowi Digital AG / WOWIPORT, Spiri.Bo, immosolve) anchor the product as a satellite/add-on tool that extends rather than replaces core housing-industry ERP systems.

Revenue is generated through annual subscriptions priced per module, with quotes tailored to the number of residential units managed and the modules selected; pricing is not publicly disclosed. The company sells exclusively through a direct, sales-led motion targeting enterprise and mid-market housing cooperatives (Wohnungsgenossenschaften), municipal housing companies, and property management firms across the DACH region, supported by a structured webinar program, content marketing, industry events (including the PropTech Summit 2025), and partner referrals. Named customers include HANSA Baugenossenschaft, gewoge AG, hanova WOHNEN, BGFG (~7,300 apartments), altoba, and Wohnbau Mainz; the company reports over 93% customer satisfaction. The firm is privately held by its managing directors Sebastian Zacherl and Kim Meadowcroft, with no disclosed external funding.

Core offering

immo-portal-services GmbH develops and sells the immo-office SaaS platform — a modular, mobile-capable software suite for digitizing processes in the German residential property management industry (Wohnungswirtschaft). The offering comprises five core modules (Instandhaltung, Verkehrssicherung, Mieterwechsel, Kundenmanagement, Rechnungseingang) plus the Handwerkerportal add-on, sold via annual subscription to housing cooperatives, municipal and private housing companies, and property managers in the DACH region.

Product overview

immo-office is a modular SaaS platform for digitizing processes in the housing and real estate management industry. The platform consists of five core modules (Instandhaltung, Verkehrssicherung, Mieterwechsel, Kundenmanagement, and Rechnungseingang) plus a Handwerkerportal for artisan coordination. All modules are mobile-capable with offline synchronization, connect via standardized interfaces to common ERP systems in the housing industry, and share a common data architecture with the ability to generate linked orders from other modules (e.g., creating maintenance work orders directly from customer tickets or inspection reports).

Direct peers

• Aareon AG: Leading German provider of ERP and software solutions for the housing and real estate industry, with whom immo-office has a formal partnership and standardized interfaces. Aareon also competes with immo-office by offering built-in modules (ticketing, mobile workflows, invoice processing) that overlap directly with immo-office's five product modules.
• CAS Software AG (CAS Haussoft): Long-established German provider of ERP and CRM software for small and mid-sized housing companies, including property management and tenant administration workflows that overlap with immo-office's Kundenmanagement and Instandhaltung modules.
• Dr. Klein Wowi Digital AG (WOWIPORT, Hypoport SE): Hypoport SE subsidiary operating WOWIPORT, one of the dominant web-based ERP systems for residential property management in DACH. Immo-office is an officially contracted partner solution under the OPEN WOWI program; WOWIPORT itself competes for the same digitalization budget when housing companies select native modules versus add-ons.
• Aktorion GmbH / Rex Software: German property management software vendor serving residential and commercial real estate, including tenant administration and digital workflows that overlap with immo-office's modular ERP-satellite approach.

Regional players

• iX-Haus GmbH: German-based provider of property management and ERP software for the housing industry with regional concentration. Comparable to immo-office in serving Wohnungsgenossenschaften and offering digital modules for residential workflows, but with a different footprint and product structure.

Broad incumbents

• Haufe Group (Haufe-Lexware / Haufe Real Estate): Large diversified German software, content, and services provider that offers property management and ERP-adjacent solutions among a broader portfolio of business software. Overlaps with immo-office's invoicing, document management, and case management workflows but serves a much broader customer base.
• Salesforce Industries (Real Estate Cloud): Global CRM and case management platform with industry-specific real-estate extensions. Competes broadly with immo-office's Kundenmanagement ticketing and case management capabilities, particularly for larger enterprises seeking a global vendor over a vertical-specialist.
• SAP SE (SAP RE / SAP S/4HANA Real Estate): Global enterprise software incumbent with real estate management capabilities targeting larger property portfolios. Immo-office is positioned as a satellite for ERP systems including SAP, and SAP competes upstream as the broader real-estate ERP of record for very large real estate companies.

Emerging players

• Allthings Technologies AG: Swiss-German PropTech operating a tenant experience and building operating system for residential and commercial real estate. Adjacent to immo-office's Kundenmanagement and tenant-facing modules; emerges as potential competition or partnership in tenant service digitization.
• Empro GmbH (immosolve): CRM and digital rental management provider for real estate brokers and the housing industry. Immo-office co-hosts events with immosolve and has an integration partnership; their CRM offering competes for part of the tenant-management and rental-process workflow that immo-office's Kundenmanagement addresses.
