An AI solution built to automate the workflows and processes of accounting professionals is only as reliable as the data upon which it rests.
In accounting, tax and audit, that data cannot come from an indiscriminate crawl of the open web. It must be the authoritative material that governs the profession itself: primary legislation, judicial decisions, guidance issued by the tax authorities, accounting and auditing standards, and collective agreements.
These, and these alone, are the sources Taxxa.ai indexes. We draw them directly from their official, first-party publishers and renew each one daily, so that you never rely on an outdated record. And because every statement is traced to its origin at the level of the paragraph, any fact can be verified in seconds. The system performs the retrieval; the professional remains in command of the quality.
Public sources are only half of the equation. Taxxa.ai can also index your own private data: client financial records, internal guidance and working templates. Uniting the two, the public corpus and your private context, opens the door to automation that would otherwise demand hours of manual work, such as verifying a client's annual financial statements against both the applicable standards and their own records, one of the most common use cases performed within Taxxa.
