A property manager is hit twice.
Invoices from trades, utilities, metering firms and insurers land in one inbox, but they belong to a different legal entity each time: this condominium association, that landlord, or the management company itself. Receiving structured e-invoices has been mandatory for every domestic business since January 2025, with no exemption at all, while issuing them is phased in from 2027 for issuers above 800,000 euros of prior-year turnover. Being VAT-exempt does not put you outside: the German Ministry of Finance explicitly counts residential landlords as businesses that must be able to receive e-invoices.
The structured file does not know your property.
An EN 16931 data set carries the VAT-mandatory fields. It does not carry the building, the cost type, the maintenance job or the labour-cost share a German tenant needs for the section 35a income tax credit. Aareon says so plainly in its own FAQ: data beyond the standard, such as section 35a information, has to be arranged per supplier during the implementation project. That gap is where the manual work survives the format change.
From one inbox to the right ledger.
We build the route between your existing systems: one receiving address per client entity, validation against the current rules, enrichment with building, cost type and job, a documented approval path, the hand-over to your ERP and the archive, and the outgoing side for management fees, rent invoices and commercial settlements. Then we keep operating it. The entry point is a pilot on one real month of your invoice traffic from 2,900 €, credited in full.
