Document type 13
Self-billed debit note: the buyer issues a debit to add to a supplier's self-billed amount.
Type 13 is the self-billed mirror of a debit note. The buyer (who issued the original self-billed invoice) issues a debit note to themselves, increasing what's owed to the supplier. Useful when the original self-billed amount was too low: late-arriving line items, FX adjustments, or contract clauses that trigger after the fact.
Four common scenarios.
- 01Tax agent adding fees to a previously-self-billed client invoice (e.g. late submission penalty).
- 02Procurement team paying a supplier more for additional work beyond the original self-billed scope.
- 03Logistics buyer adding accessorial charges (detention, demurrage) to a metered-service self-bill.
- 04Co-operative settling a member's higher-than-estimated patronage dividend.
What this document type carries that a generic invoice doesn't.
- Original self-billed invoice reference: UUID of the parent type-11 document.
- Party-flip preserved: buyer is the issuer, supplier receives the additional credit.
- Supplier MSIC code required.
- Reason code from LHDN's structured list, positive-sign amounts.
How Bridge handles it
Same pipeline as every other type.
Type 13 uses the same live document pipeline as type 12, with the required debit-note values. REST API and manual entry are available today; CSV import and the activity audit log are coming soon.
