Cord's tax stamping runs in production with the SAT through a certified PAC. The architecture is multi-country by design — each new market is added as its own adapter, no core rewrite required.

CFDI COMPLIANCE

Real stamping, an architecture built to grow.

Every approved quote can be invoiced as a real CFDI 4.0 with the SAT, using your own Digital Seal Certificate (CSD) and RFC — not a simulation. The engine is built as one adapter per country, so adding a new market doesn't touch the core.

The details that actually matter when invoicing

Every organization sets its own VAT rate and ISR/VAT withholdings in Settings — the engine applies them without anyone having to remember.

Real or simulated, every invoice issued gets recorded — you never lose track of what was stamped and when.

If a client has no tax regime on file, Cord invoices to the public general audience instead of blocking the stamp.

FREQUENTLY ASKED QUESTIONS

What developers ask about US/MX Tax.

Is the CFDI 4.0 for Mexico real or a test?

It's real: Cord stamps invoices with the SAT via a certified PAC (Facturapi) once you connect your CSD. Without a key configured, stamping runs in simulated mode so you can test the flow risk-free.

Does Cord already issue complete tax invoices for the United States?

Not yet. The architecture is ready for a US invoicing adapter (commercial invoice), but today the only tax provider in production is Mexico via CFDI 4.0. If you need real US invoicing today, that's not a case Cord covers yet — reach out if you'd like us to prioritize it.

Can I have one legal entity in Mexico and another in the US under the same account?

Not yet. Each Cord account has a single tax country. To operate two legal entities in different countries you'll need two separate accounts — there's no native support for multiple entities under one organization.
