# Invoices & documents

Billing with structure: separate number ranges per company for outgoing and incoming invoices, credit notes and cancellations.

Documents are not a by-product but an obligation: sequential numbers, correct tax, traceable changes. miegroup creates them from the order and files them in an audit-proof way.

- Invoice, cancellation, correction, credit note and prepayment — each with its own number range per company.
- Drafts without a number: the number is drawn only on finalisation.
- Incoming invoices are read from a mailbox, booked and evaluated in a monthly report.
- Documents as PDF to the customer, optionally with the order confirmation.

## FAQ

### Can each company keep its own invoice numbers?

Yes. Each company has its own number ranges with a prefix for outgoing invoices, credit notes, cancellations and quotes; the number is assigned only when finalised, drafts stay unnumbered.

### Which document types are available?

Invoice, quote, credit note, cancellation, delivery note and packing list — as PDFs with the type in the title. Incoming invoices are recognised by AI and OCR and booked with a duplicate check; a monthly report summarises everything.

### Is dunning included?

Yes, as an automation per company: three dunning levels at least seven days apart that you switch on deliberately. Only cases from the moment of activation are considered, never the backlog.
