Built by people who understand SALT as a service business.
We spent years inside the manual workflow — the spreadsheets, the jurisdictional research, the audit scrambles. L3i is the platform we wished we'd had.
Indirect tax has run on manual labor for decades. We rebuilt it as one connected platform.
Advisory teams juggle client data, ever-changing tax law, nexus thresholds, and deadlines — across spreadsheets, email, and institutional memory. The work is fragmented, repetitive, and error-prone.
We built L3i to run the entire lifecycle. Onboard a client, normalize their data once, and every report — nexus to returns — comes off that single foundation. It reflects how firms actually deliver SALT: as a professional service, under their own brand, with the firm in control of the relationship.
AI is infrastructure, not the pitch: it normalizes the data and assists the analysis, while a deterministic rules engine makes the determinations. Teams work faster, the whole book stays current, and audit readiness becomes a byproduct — not a separate project.
A few things we hold to.
The advisor owns the relationship
L3i powers the firm’s service. It never disintermediates the advisor or sells past them to their client.
AI where it helps, deterministic where it counts
AI does the research and reading; a deterministic rules engine makes the determinations — fast where it helps, defensible where it counts. Not a black box.
Audit readiness is earned, not added
When the workflow is connected and automated, being audit-ready is simply how the work comes out.
