# Update billing info

> Set the billing contact, delivery emails, address, and tax ID for your invoices

`PUT /api/v2/billing/info`

Updates the billing (payer) info Scope3 invoices you with. Admin-only. Send at
least one field; omitted fields are left unchanged. The response returns the
full updated record. At minimum, Scope3 needs a payer name (`contactName`) and
a payer address (`address`, `city`, `countryAlpha2`) to issue an invoice — set
both before your first billing cycle. Also available in the UI under
**Settings → Billing**.
