## create\_business\_client
`Écriture`
Create a B2B (business) client. An email is required (used as unique key). Provide the business identity (legalName, siret, vatNumber...) — tip: call search\_business first to get accurate data. Optionally add multiple contacts (accounting, purchasing...) and payment terms (delayDays, creditLimit).
Contact email (unique per client)
Business identity & commercial terms
Addresses if you already have them (e.g. extracted from a business card). If omitted AND a SIRET is provided, the billing address is auto-fetched from the registry.
## enrich\_client\_from\_siret
`Écriture`
Turn an existing client into a B2B client by enriching it from a SIRET via the French company registry. Fills legalName, SIREN, VAT, APE, legal form, and adds the director as primary contact (if no manual contact exists). Preserves manually-entered contacts and payment terms.
