How it works

Four steps to a finished statement.

1
Upload receipts
Upload cost receipts as PDF, photo or scan. Line items and amounts are read automatically, no tedious retyping.
2
Answer follow-up questions
A few targeted questions, for example about the allocation key or the billing period.
3
Receive the PDF
The finished statement as a PDF, checked for BGH compliance, ready to send to tenants.
4
Review and approve
Your case workers review every line item, add details where needed and approve the statement for sending.

What happens technically.

The tool reads the uploaded receipts, classifies line items and amounts and assigns them to the apportionable cost types. It checks the statement against § 556 BGB and current BGH case law, for example on the twelve-month billing deadline and the right to inspect receipts, and then fills in your organisation's template.

Before approval, your case workers can review and supplement every line item. Factual control stays with you, while the routine work runs automatically.

What the tool ensures
  • Correct allocation keys: living space, number of occupants or consumption, cleanly apportioned to tenants.
  • Apportionability checked: only permissible cost types under the BetrKV enter the statement.
  • Traceable: every line item traces back to its underlying receipt, ready for receipt inspection.
Legal basis: § 556 BGB (agreements on operating costs), the Operating Costs Ordinance (BetrKV), billing deadline of twelve months after the end of the billing period.
