Vavang Invoice

Vavang Invoice adds a France-oriented invoicing compliance layer to Sylius 2.1/2.2, built on top of Sylius InvoicingPlugin.

The plugin does not replace Sylius invoicing. It complements the source invoice with the data required by the fiscal and regulatory pipeline: seller/customer snapshots, classification, immutable data, Factur-X generation, validation, asynchronous transmission, audit and operational tooling.

What the plugin protects

A historical invoice must not be recomputed from an order or product catalog that changed later. Vavang freezes the relevant fiscal data and runs the compliance pipeline from that immutable representation.

The core rule is simple: the invoiced record remains historical truth; current business data does not rewrite the past.

Documentation scope

These pages document the contract supported by the current version. Advanced guides — detailed compliance, integrations, extension points, maintenance and operations — are published in their dedicated sections as those contracts stabilize.

Product documentation is not tax or legal advice. Technical configuration can validate a representation; it does not determine the merchant’s actual fiscal position.
