Different types of acknowledgement messages reflect the processing status of document:

• Acknowledgement message 12 - The document was successfully received by the recipient or their electronic exchange provider.

• Acknowledgement message 27 - A business/content rejection from the recipient (optional, applies to invoices only).
• Acknowledgement message 29 - A bussines/content confirmation from the recipient (optional, applies to invoices only).

When Are Acknowledgements Received?

• Types 12 or -99 are usually received within minutes after sending.
• If recipient's provider is not bizBox, the acknowledgement is send immediately after technical processing.
• If the provider is bizBox, the acknowledgement is sent once the recipient manually confirms or rejects the invoice content.

Types 27 or 29 (content-based) may arrive later, only if the recipient manually confirms or rejects the invoice content.

• Type 12 typically contains no description.
  
• Types -99, 27 and 29 often contain error details or messages from recipient.
