Configurable note on automatic invoices

9 October 2026 — Each connected account and each store can now carry a note that Factuarea writes in the notes of every invoice it issues automatically from that account or store. Read the Stripe auto-invoicing guide and Ecommerce stores for the whole flow.

• Configurable note — invoice_note is a string or null of up to 500 characters, trimmed. It is null by default, and then the automatic invoices carry no note; the only text they get is, when a charge or an order was in another currency, the line with the conversion to EUR and the ECB rate applied.
• How to set it — on the update operations, omitting invoice_note leaves it as it is, null or an empty string clears it and a text assigns it. More than 500 characters returns 422 parameter_invalid_value with param invoice_note.
• Where it is returned — connected accounts and stores return invoice_note in every response that describes them.
• Default due date — the invoices that Factuarea issues automatically, from gateway charges and from store orders, take the default due date of any invoice: 30 days from the issue date.
• MCP tools — update_stripe_connected_account and update_store accept invoice_note.

Integrations that do not send the field need no changes: automatic invoices carry no note until one is configured.
