Legal invoices in Mexico, commercial everywhere else, over the API.

Cord Invoicing issues invoices from the app or over the API and adapts the document to your business's country: CFDI 4.0 stamped with Mexico's SAT, and a commercial invoice with each country's taxes everywhere else. Spain has the Verifactu registry built and in the process of activation with the AEAT.

FULL CYCLE

Create, issue, collect and correct from your code.

POST /api/v1/facturas creates a draft. Then, on that same invoice, you issue it, email it with the PDF attached, record a full or partial payment, void it or create a credit note. Each action fires its event, so your system can react by webhook.

Draft first: nothing is stamped until you issue
Partial payments capped at the real balance
invoice.finalized, invoice.paid and invoice.voided as webhooks

BY COUNTRY

The right document for each country.

In Mexico, Cord stamps CFDI 4.0 with the SAT using your digital seal certificate through an authorized provider. Everywhere else it issues a commercial invoice with that country's per-line taxes, such as state sales tax in the United States or VAT and IRPF in Spain. For Spain, the Verifactu registry with a chained SHA-256 hash is built and verified against the AEAT's official examples; it goes live once registration with the AEAT is complete.

Mexico: CFDI 4.0 with the SAT UUID, PDF and XML
Per-line taxes and withholdings, not a flat rate
Spain: Verifactu built, pending activation with the AEAT

FREQUENTLY ASKED QUESTIONS

What developers ask about Tax invoicing.

Does Cord stamp real CFDI 4.0?

Yes. In Mexico, Cord stamps CFDI 4.0 with the SAT using your digital seal certificate (CSD) through an authorized provider (PAC), and returns the UUID, the PDF and the XML.

Can I issue invoices over the API?

Yes. POST /api/v1/facturas creates a draft and POST /api/v1/facturas/{id} with action finalize issues it. The same route accepts send, payment, void and credit_note.

Does Cord issue tax invoices in the United States?

Cord issues commercial invoices with state sales tax. The United States has no national e-invoicing system like the CFDI, so the commercial invoice is the usual document.

Does Cord already register invoices with the AEAT through Verifactu?

Not yet. The Verifactu registry is built and verified against the AEAT's official examples, but going live depends on Cord's registration as the software producer with the AEAT. Until then, invoices in Spain are issued as commercial invoices.

What happens if issuing fails?

The invoice keeps the tax status "error" and is not marked as issued. You see it in the app and over the API, and can fix the data and issue again.
