After the invoice
What runs automatically afterwards
Failed payments, credit notes and wallet payments: three processes your team does not have to touch.
Fixed intervals
Automatic retries
If a direct debit or card payment fails, for example due to insufficient funds, OB7 retries the collection at fixed intervals per payment method.
Your team only sees the invoices that are still open afterwards.
Own number range
Credit notes without manual work
When an invoice is cancelled, OB7 creates the credit note automatically: its own number range, its own template, as a PDF by email to the customer.
You trigger the refund with your payment provider.
No registration
Pay like everyday life
Apple Pay, Google Pay and PayPal for ad-hoc charging: drivers pay without registration and without typing a card number.
At Stadtwerke Stuttgart, 81 % of payments run through Apple Pay and PayPal; before, everything ran on credit cards.

FAQs
Frequently Asked Questions About Billing
What operators and municipal utilities ask before launch.
Does OB7 bill our customers?
No. You bill your customers. OB7 calculates the price from your price configuration, creates the document in your brand and starts collection with your payment provider.
When does the customer receive the invoice?
Ad-hoc guests receive the receipt right after the CDR, by e-mail if an address is on file. Charging-card customers and employees receive a collective invoice as soon as the configured amount is reached or the cycle in days ends. Before that, OB7 waits 24 hours for corrections to the CDR.
Who is the sender on the invoice?
You. Logo, company data, tax number, accent colour and texts come from your template. OB7 does not appear on any document. Go to the eMSP backend
How are VAT and currency handled?
You enter gross prices. Tax rate and currency come from the site group and are frozen on the session. The invoice shows net, tax and gross per tax rate.
What happens if a session costs more than the pre-authorisation?
That is your setting. Either OB7 waives the difference as goodwill, or it bills the reserved amount and charges the remainder through the regular billing cycle.
What happens with failed payments?
OB7 retries the charge automatically, within fixed limits per payment method. The status of every invoice is visible in the eMSP backend. Dunning with fees is not part of the product; operators use their existing process for that. See payment methods
How do credit notes and refunds work?
When an invoice is cancelled, OB7 automatically creates a credit note with its own number and template and sends it to the customer as a PDF. You trigger the refund with your payment provider.
Is there a DATEV or XRechnung export?
Yes. OB7 delivers invoices and credit notes as a DATEV export for your accounting and as XRechnung for B2B e-invoices. You can also export sessions and document data as CSV, XLSX and JSON, with optional automatic delivery to your cloud storage.
How are business customers billed?
Business customers receive invoices like all registered customers, with the billing address on file and the same collective-invoice rule. A breakdown by cost centre or vehicle does not exist today.
