Day 7: Archive Submitted XML Invoices for Compliance #irbarchive

IRBM requires that submitted invoice data be stored securely and made available for auditing purposes. To meet this requirement, always archive the final signed XML for each invoice after submission.

โœ… When to archive:

Immediately after the final XML is signed, base64-encoded, and submitted to IRBM โ€” store that exact copy.

โœ… Laravel Example:


Storage::disk('s3')->put("invoices/xml/{$invoice->id}_submitted.xml", $signedXmlContent);

$invoice->update([
    'irb_xml_path' => "invoices/xml/{$invoice->id}_submitted.xml",
]);

โœ… Recommended Column:

  • irb_xml_path (string)

๐Ÿ’ก Tips:

  • โœ… Use S3 or external backup storage with versioning enabled
  • โœ… Include invoice_no and submission_date in the filename
  • โœ… Mark files as immutable (write-once) for legal protection

โœ… Use case:

This archive is useful for legal disputes, audits, and regenerating invoices for customers.

Coming up in Day 8:

Weโ€™ll create a report to track submission statuses across all invoices with filters for failed, submitted, and pending cases.
