Document references - Invopop

Documents point at each other by envelope UUID. Provide your own UUIDs if you want to use internal identifiers, or leave the field blank and Invopop will generate one. Each schema carries those references in its own properties.

Reference	Property
Credit or debit note → invoice	`preceding` reference on the correcting document. The original stays valid.
Corrective invoice → invoice	`preceding` reference. The corrective document replaces the original.
Payment → invoices	A `document` reference on each `lines` entry, naming the document being settled.
Status → document	A `doc` reference on each `lines` entry, naming the document the event concerns.
Invoice → order or despatch advice	`ordering.purchases`, `ordering.sales`, `ordering.despatch` and `ordering.receiving` references to the earlier documents.
Document → party or item	UUID reference on the embedded `supplier`, `customer` or line `item`.

Regimes that require more

Some regimes require more than a reference to the original document.

Regime	Requirement
Colombia	Credit notes must carry the original invoice’s CUFE code.
Spain	VERI*FACTU credit notes must reproduce a breakdown of the original invoice’s taxes.
Mexico	Corrections must carry the original invoice’s SAT UUID stamp.
Greece	Corrections must carry the original invoice’s IAPR mark.

Correcting from the Console or the API builds these references for you — see Correct an invoice.

Seeing what is linked

To see which documents Invopop has actually linked to a given entry, use its Related tab, described in Document contents.

Related lookups run in one direction. A supplier’s Related tab lists its invoices, but an invoice does not show a link back to the supplier. A referenced party must also be signed before its documents appear.
