What onOffice Software does
onOffice GmbH, founded in 2001 in Aachen, Germany, is a privately held software vendor that builds and operates onOffice enterprise, a cloud-based SaaS platform purpose-built for independent real estate brokerages. The platform consolidates property management, contact/CRM, marketing automation, document generation, enquiry handling, calendar and task management, statistics and reporting, and CTI-based phone integration into a single system sold in three tiers — Essential, Premium, and Expert — plus a catalog of branded add-on modules including onOffice AI-Studio, Process Manager, Enquiry Manager, Phone Module, onOffice Sync, Statistics Toolkit, onPointment (online appointment booking), Showcase TV, and Project Management. The technical foundation is a JSON API-first architecture running on EU-hosted infrastructure (reportedly 100+ servers, 17 database clusters, 2 data centers, 2 TB of monthly data migration, and a 2+ million-line code base), with deep integrations to 150+ real estate portals, multiple phone-system vendors via CTI, Microsoft 365, WhatsApp, DeepL, and ChatGPT, plus a WordPress-based website builder (onOffice WP Websites) and an in-app Marketplace for third-party services.
The business model is recurring SaaS subscription revenue, supplemented by one-time setup fees (payable within 14 days of contract signature) and ancillary services such as Statistics Packages and additional storage. Pricing is quote-based and not publicly disclosed; customers engage via a 7-day free trial, website-driven lead capture, and direct enterprise sales through regional offices in Germany, the UK, Austria, Switzerland, Italy, Spain, and Croatia. The customer base spans small independent brokerages up to large enterprise accounts — including VON POLL IMMOBILIEN (1,500+ employees across 400+ European locations, customer since 2012), RE/MAX Regensburg (customer since 2007, the leading RE/MAX office in the DACH region), and AssetGate GmbH (an Intrum Group subsidiary specializing in distressed real estate assets). The company is founder-owned by Stefan Mantl, has never disclosed external funding, and operates without a parent company or public listing.

onOffice Software competitors and assessment
Company assessmentDirect peers
- casavi: German SaaS for property managers and real estate companies, offering tenant communication, CRM, and workflow automation. Closely comparable to onOffice in target customer (real estate professionals) and DACH market focus, with overlapping functionality in CRM, marketing automation, and document workflows.
- onrequest GmbH: German provider of CRM and ERP software for real estate brokerages and property managers. Direct competitor in the German-speaking vertical SaaS market with comparable offerings around property management, contact management, and marketing automation for real estate professionals.
- FlowFact GmbH: German real estate CRM and marketing software for brokers, agents, and property managers. Competes with onOffice on the same core use cases (property/contact management, portal distribution, marketing workflows) for the independent brokerage segment in DACH.
- Propstack: Cloud-based CRM and property management software for real estate brokerages, headquartered in Germany. Targets the same SMB and mid-market broker segment with property, contact, and transaction management functionality comparable to onOffice enterprise.
- Apimo: French SaaS for real estate agencies offering property management, CRM, and marketing tools. Comparable in product scope and vertical focus, though primarily serving the French-speaking market rather than the German-speaking market that is onOffice's stronghold.
- Hektor: French real estate CRM and marketing platform for independent agencies and networks. Comparable vertical focus and product surface (CRM, property listings, marketing) to onOffice enterprise, with regional overlap limited to Southern European expansion markets.
Broad incumbents
- Aareon AG: One of Europe's largest real estate software vendors, owned by Advent International. Serves a much broader portfolio (housing industry, property management, real estate) than onOffice, but overlaps directly on CRM and ERP functionality for real estate companies and represents a major incumbent in DACH.
- RealPage: Large US-based SaaS provider for the real estate industry, covering property management, marketing, AI, and analytics. Significantly broader portfolio than onOffice; relevant as a scale benchmark for vertical real estate SaaS and as a potential competitor in any future US expansion.
- Yardi Systems: Privately held US incumbent providing comprehensive real estate software across residential, commercial, and broker segments. Comparable in vertical depth but vastly larger scale, and relevant as a competitive reference point for end-to-end real estate software suites.
- Salesforce: Global CRM platform with growing real estate industry clouds and partner ecosystem. Represents the broadest competitive threat to onOffice from a horizontal CRM perspective, particularly if mid-market brokers choose platform breadth over vertical specialization.
