Whether you're expanding abroad from Mexico or landing there as a global company, Light keeps every entity on one ledger.
NIF
Report under Mexican Financial Reporting Standards (NIF) and group standards side by side with multibook — no parallel spreadsheets.
IVA
Standard 16%, the reduced border-region rate, zero-rated and exempt supplies applied via tax codes as transactions post — with IVA and ISR withholding handled as their own tax types.
CFDI 4.0
Issue and receive CFDI 4.0 stamped through a certified PAC — invoices, credit notes, payment complements, and withholding certificates, outbound and inbound.
Mexican banking
Connect Mexican bank accounts via host-to-host integration or bank feeds — transactions reconcile automatically, vendors get paid by SPEI to their CLABE in MXN.
IVA, from CFDI to the SAT
In Mexico the invoice is the tax filing. Light stamps every document at source and builds the monthly returns from the same postings — nothing reconciled after the fact.
CFDI 4.0, both directions
Every sales invoice is stamped as valid CFDI 4.0 XML through a certified PAC — RFC, régimen fiscal, uso del CFDI, and código postal validated before it goes out — and supplier CFDIs arrive through the same connection, matched to bills in your AP workflow with no re-keying. Cancellations follow the SAT's acceptance rules, with each document's UUID and status tracked on the ledger entry itself.
Cash-basis IVA and the payment complement
Mexican IVA is recognized when cash moves, not when the invoice is issued. Light issues the complemento de pago on settlement and shifts the IVA accordingly, so acreditable and trasladado balances match what the SAT expects on the monthly declaration.
IVA and ISR withheld on payments to service providers post to their own accounts and flow into the withholding CFDIs and the DIOT automatically.
The periodic compliance cycle
Every recurring Mexican obligation is fed by the same CFDIs and postings — which is why one ledger matters.
Contabilidad electrónica
Monthly XML upload to the SAT — chart of accounts, trial balance, and journal entries generated straight from the ledger
DIOT
Third-party transaction report, built from supplier CFDIs and payments already recorded
Compliant with how Mexico audits
Mexican statutory requirements are built into the ledger, not bolted on.
SAT-verified trail
Every invoice carries its UUID, stamp, and cancellation status, so the audit trail starts at the tax authority itself.
Contabilidad electrónica
The código agrupador mapping, trial balance, and pólizas the SAT requires are generated from the ledger, not assembled by hand each month.
Host-to-host banking
Direct connections with major Mexican banks for statement collection and SPEI payment files at treasury-grade control.
One platform, every country you operate in
Mexico is one of the many countries Light supports out of the box — same ledger, same close process, local requirements handled per entity.
