Billing

last updated: 2025-09-10

All accounts within DownToZero operate on a prepaid basis. You must charge your account balance before consuming any resources. Each account top-up is made via IBAN/SEPA bank transfer and generates an official invoice for the transferred amount (Vorauszahlungsrechnung). This model is simple, tax-compliant, and familiar for German/EU customers.

Charging Your Account

Make a SEPA/IBAN transfer to our bank account:

Bank Details

  • IBAN: DE08100101236489344438
  • BIC: QNTODEB2XXX
  • Bank: Olinda Zweigniederlassung Deutschland, Warschauer Platz 11–13, 10245 Berlin

How to Top Up

  1. Log into the Billing Dashboard.
  2. Find your Account ID (shown on the Charge page and in your account settings).
  3. Make a SEPA/IBAN transfer using the bank details above and set the transfer reference (Verwendungszweck) to:

charge

Example: charge identity-abcdef
4. After we receive the transfer, your account balance will be credited. SEPA transfers typically take 1–2 business days.

Invoices

  • Every top-up creates an official invoice for the exact amount transferred.
  • Once your payment is processed, you can download the invoice from the Billing Dashboard.
  • Monthly usage is shown as a consumption report in the dashboard; only top-ups are invoiced.

Notes

  • Use the reference exactly as shown (charge <AccountID>). Payments without the correct reference may be delayed.
  • If your bank limits special characters, keep a space or dash between charge and your Account ID (e.g., charge identity-abcdef).
  • If your balance isn’t credited within 3 business days, contact support and include proof of transfer.
  • Unused balances remain in your account until consumed. Balances are not refundable.
