Buyer fields (formerly Checkout fields) now lets you configure one list of purchasing references for both card Checkout and pay-by-invoice orders.
What changed
Open Settings → Products → ... → Buyer fields to:
- Add up to three custom fields, shared by card Checkout and the invoice billing form
- Insert PO number and Cost centre using presets
- Collect an optional or required Contact person, automatically included as Contact on invoices generated from the invoice billing form
- Collect Phone number at card Checkout only
Invoice buyers fill the labelled fields you configured. Their answers print on the resulting invoice. Company or billing name, email, address, and VAT or tax ID remain separate billing details and do not use custom-field slots.
Card payments and invoice payments
Card buyers enter their details and pay in Stripe Checkout. Custom answers are stored on the Checkout Session; they are not automatically copied onto every Stripe-generated card or subscription invoice.
Buyers choosing an invoice-only product complete Cavuno's Billing details form instead. Cavuno generates an invoice with their references and emails a link to Stripe's invoice payment page.
See Buyer fields for setup and verification.
