The service-charge statement that's reliably correct.
Photograph your bills, get a finished statement. Nebenklar reads your invoices, allocates costs correctly under the German Operating Costs Ordinance, and explains every line in plain language — for private landlords with 1 to 10 units.
Add buildings & tenants
Capture units, floor areas and prepayments once — then everything's ready for every statement.
Photograph your bills
Simply snap or upload invoices. Nebenklar detects the amount, period and cost type automatically.
Allocate costs correctly
The engine splits each cost type by the right key and excludes non-apportionable items — fully traceable.
Generate the statement
One audit-ready statement per tenant with the balance due or credit — clearly explained and print-ready.
Legally sound and traceable
Allocation follows the German Operating Costs Ordinance — not a language model's guess. Your data sits on EU servers, and you can delete your account anytime.
