Two types of services – two types of invoices
At smarta, we distinguish between:
Ongoing services
These are the monthly fees based on your chosen smarta plan.One-time services
These include any additional services outside your plan, such as a signed BWA, an income tax form (e.g. Anlage N), or investment advice.
These two service types are billed separately. So if both apply in a given month, you may receive two invoices.
When is billing done?
Ongoing services:
Always billed on the 1st of the month, regardless of your signup date. The basis is your active smarta plan.One-time services:
Billed in the following month – for example, a certificate or tax return requested in July will be invoiced in August.
Payment options
SEPA direct debit (recommended)
If you've submitted a SEPA mandate, we’ll automatically collect the amount via our payment provider GoCardless.
This is the easiest and most secure option – no further steps required.
Bank transfer
You can also transfer the invoice amount manually. Please use the following bank details:
smarta Steuerberatungsgesellschaft mbH
OLINDA Zweigniederlassung Deutschland
IBAN: DE75100101231521160372
BIC: QNTODEB2XXX
Important: Always include the invoice number as the payment reference to ensure correct allocation.

Changes from August 2025
Until July 2025, ongoing fees were debited by Ageras GmbH via your Kontist business account.
Since August 2025, billing is handled entirely by smarta:
Invoices now come directly from smarta Steuerberatungsgesellschaft mbH
Charges are debited by smarta (if a SEPA mandate exists)
Ongoing and one-time services continue to be billed separately
Your service scope remains unchanged.
