Order Invoicer
Wix

Wix e-invoicing setup

Configure Wix checkout fields for French VAT, SIREN/SIRET, and Mexican CFDI

Order Invoicer reads the native tax ID and two kinds of Wix checkout fields: legacy customFields by their exact title, and native fields under extendedFields.namespaces._user_fields by their technical key. The value must be on the order: a reference such as a datoFiscal profile id is not enough.

How to add the fields in Wix

  1. Open your Wix dashboard and go to Checkout Settings.
  2. Click Edit under Checkout form.
  3. Click Create Field.
  4. Choose a text field for each fiscal identifier you want to collect.
  5. Set the field title to the exact value you want Order Invoicer to read.
  6. Mark the field required if your checkout should not proceed without it.
  7. Save the checkout form.

Where to map them in Order Invoicer

In Settings → Clients, turn on Look up identifiers via metadata keys and paste each field's exact title. These settings can be edited from the Launch plan.

For native fields, use the technical key instead of the displayed title in all mappings below. For example, if Wix returns cfdi_rfc, cfdi_regimen_fiscal and cfdi_uso, map them to VAT number lookup via metadata, Régimen fiscal (CFDI) via metadata and Uso CFDI via metadata, respectively. These are examples, not required Wix field names. Copy the keys actually present on your orders. A legacy field with the same key takes priority.

France

  • VAT number: use Wix's native checkout tax ID field. If the VAT number is in a custom field, paste its title into VAT number lookup via metadata.
  • SIREN: create a custom field and paste its title into SIREN lookup via metadata.
  • SIRET: create a custom field and paste its title into SIRET lookup via metadata.
  • E-invoicing address (Pennylane and Evoliz, Growth plan): create a custom field holding the buyer's address in the e-invoicing directory (SIREN, SIREN_SIRET or SIREN_code, e.g. 123456782_12345678200010) and paste its title into E-invoicing address via metadata.

Mexico

  • RFC: use Wix's native checkout tax ID field. If your checkout doesn't show it, create an RFC custom field and paste its title into VAT number lookup via metadata.
  • Régimen fiscal: create a custom field and paste its title into Régimen fiscal (CFDI) via metadata.
  • Uso CFDI: create a custom field and paste its title into Uso CFDI via metadata.

The Régimen fiscal and Uso CFDI values can be SAT codes alone (616, G03, S01) or a code followed by a label: 616 - Sin obligaciones fiscales and S01 - Sin efectos fiscales are sent as 616 and S01. The RFC is kept in full. Other values are not automatically corrected.

When the configured keys are cfdi_regimen_fiscal and cfdi_uso, the older keys regimen_fiscal_1 and uso_cfdi are also recognized if the configured value is missing, blank or not text. A non-blank text value from the configured key takes precedence. This fallback does not apply to other configured keys.

A settings change does not update orders already imported. They need to be fetched from Wix again. Refreshing an order also reruns its conversion to your invoicing tool.

Tip

Do not translate the field title after mapping it in Order Invoicer.
