Compliance Dashboard

Compliance Dashboard

Real-time compliance monitoring with penalty exposure, offer rates, and filing status at a glance.

Six engines. One workflow.

Most ACA tools wrap a thin UI over a spreadsheet. We built the actual regulations as code.

Data Hub

Drop your CSVs — demographics, payroll, benefits, W-2s. Client-side parsing, per-row validation, and Excel-aware templates.

Compliance Engines

ALE determination, measurement periods, ACA codes, affordability safe harbors, penalty calculations — all built to the letter of §4980H.

IRS-Accurate Forms

Real IRS PDF blanks with pixel-correct overlays. 1094-C and 1095-C forms that match the IRS schema byte-for-byte.

Federal & State Filing

IRS AIR e-filing plus 6 state mandates (CA, NJ, MA, RI, VT, DC). One workflow for every jurisdiction.

Employee Distribution

Print, mail, email, or secure-link delivery. Consent-aware distribution with full audit trail.

Risk Dashboard

Real-dollar penalty exposure, not vague badges. See §4980H(a) and (b) risk by employee and month.

Multi-Client Mode

Manage 20 clients without 20 logins. Keyboard-first navigation with sub-second tenant switching.

Built for precision. Designed for clarity.

Every screen is purpose-built to make ACA compliance straightforward.

Security & Compliance

Built for PII. Designed for audits. Every customer asks about security — here are the answers.
