Frequently Asked Questions

What are electronic accounting XML files?

XML files required by Mexico's SAT: Chart of Accounts (account-to-grouper mapping), Trial Balance (monthly balances), and Journal Entries (transaction details). Must be submitted monthly or on demand.

Why does the Chart of Accounts XML fail?

Accounts missing SAT grouper codes. Every detail account must map to the official SAT grouper catalog.

Why do journal entries fail XML validation?

Missing CFDI UUIDs on invoiced transactions, empty descriptions, invalid account codes, or incorrect third-party RFC numbers.

Why doesn't the trial balance match?

Debits and credits don't sum equally, or there are rounding differences of a few cents.
