How do housing companies digitalise their entire letting process sustainably?+
The letting process becomes sustainably digital when marketing, applicant management, viewings, contract signature and tenant communication run in one data model and are connected to the ERP via an interface. Five building blocks are decisive: multiposting from a single source, GDPR- and AGG-compliant pre-qualification with matching, bot protection and verified profiles, digital signature without media breaks, and a tenant portal that continues the relationship after the move-in.
What causes media breaks in the letting process of large housing portfolios?+
Media breaks occur when property data sits in the ERP, listings on portals, applications in the email inbox, viewings in the calendar and contracts on paper or in a separate signature tool. Every hand-over costs time and creates errors. The solution is a letting platform that maps these steps in one system and exchanges data with the ERP via an interface only at the start and the end.
Why do housing companies often fail at digitalising the letting process?+
Common causes: letting is introduced as a peripheral ERP module and lacks the depth that day-to-day work requires; applicant bots and duplicate profiles flood the process; legally, the housing entitlement certificate (Wohnberechtigungsschein, WBS) can only be checked after the viewing; teams are not trained by role; and the business case is not measured. Successful projects start with the letting portal, measure vacancy days and time per letting, and add signature and tenant portal step by step.
