Double-Entry Accounting Primer

Double-entry accounting records every transaction as at least one debit and one matching credit, so the books always balance. An invoice increases what a customer owes you (a debit to receivables) and increases revenue (a credit) — the two entries are inseparable.

In Travix Cloud, every financial document — invoice, payment, receipt, journal — is a voucher. A voucher moves through draft, submit, approve, and post; only a posted voucher touches the ledger. Corrections to a posted voucher happen through reversals, never a silent edit, so the audit trail stays complete.

Every posted entry links to the one before it with a SHA-256 hash chain, so tampering with historical data is detectable, not just discouraged by policy. Your trial balance, P&L, and balance sheet get generated directly from this ledger — they can't drift from it.
