What is the difference between advance payments and flat fees?

In short: advance payments are prepayments on actual operating costs; flat fees are fixed amounts without individual accounting. Which system applies often depends on the rental contract and legal rules.

  • Advance payments: monthly prepayments (payment), the landlord can demand additional payments if actual costs are higher.
  • Flat fee: fixed amount, often without individual receipts (receipts), refunds or additional charges are limited.
  • Billing: For advances a yearly settlement is common; for flat fees the contract states whether and how settlements occur.
In many cases the exact wording of the rental contract determines advance or flat fee.

Rights and obligations

The legal bases for operating costs and billing are found in the Tenancy Law and complementarily in the General Civil Code.[1][2] Landlords must make the settlement comprehensible and provide receipts if additional claims are made.

Advance payments

With advance payments tenants regularly pay instalments; after the accounting period the landlord must present a detailed settlement.

  • Payment method: monthly or quarterly prepayments (payment) are common.
  • Receipts: On request, the landlord must provide receipts or a comprehensible cost breakdown (receipts).
  • Deadlines: Check accounts promptly and respond within deadlines to preserve rights.
Keep all invoices and proof of payment at least for the length of the accounting period.

Flat fee

Flat fees simplify billing but offer less transparency. Whether a flat fee is permissible can depend on the contract and legal requirements.

  • Fixed amount: The flat fee is a fixed sum independent of actual costs (payment).
  • Receipt obligation: Often detailed receipts are omitted, so tenants should ask before signing the contract (receipts).

What to do if unclear?

First check the settlement in writing, request missing receipts, and note deadlines. If answers are missing or the settlement is implausible, send a formal request and set deadlines.[3]

Clear, written communication with a deadline makes later steps before courts or authorities easier.

FAQ

Can the landlord demand advance payments without settlement?
No: Advance payments must later be explained by a settlement; additional claims are only permissible with a comprehensible justification.
How quickly must I respond to an operating cost settlement?
Check the settlement immediately and respond within the contractually or legally provided deadlines; otherwise claims may become harder to enforce.
What should I watch for before signing a contract?
Pay attention to clear rules on advances, flat fees, billing frequency and provision of receipts.

How-To

  1. Collect receipts: Gather all invoices, proof of payment and past settlements.
  2. Send request: Ask in writing for a detailed settlement and copies of receipts.
  3. Set deadline: Give the landlord a reasonable deadline to provide the documents (e.g. 14 days).
  4. Seek advice: Contact tenant associations or legal advice if unclear items remain.
  5. Final step: If necessary, file a claim at the district court or use mediation services.
