Turn your firm's SALT judgment into IP that compounds.
Every nexus call, taxability position, and VDA your experts make is captured, reused, and sharpened — instead of re-derived from scratch and lost at turnover. The whole lifecycle, audit-ready from day one.
Built for accounting firms running SALT practices across North America.
Every cycle, your hardest-won expertise leaks away.
Made once, then lost — to a closed workbook, a departure, or a rule change. You pay to re-derive what your firm already knew.
Every study starts cold
The judgment behind a nexus call or taxability position is made once, lives in the cells, and is re-derived from scratch next time.
Knowledge walks out the door
When a senior practitioner leaves, the reasoning that set your SALT practice apart leaves with them.
Positions quietly go stale
A rule changes — and nothing flags what it just invalidated across your book.
Onboard once. The rest is one continuous loop.
AI-assisted — each client in fast.
Transactions, documents, and more.
AI cleans and structures the data.
Any report, from the same foundation.
Ask the data questions; surface risk.
Deadlines and status across the book.

Messy exports become a clean foundation you can query.
Stop re-deriving. Start compounding.
