The foundation employers still need, delivered with more intelligence.

Sunnyside helps organizations manage the weight of employment through strong operational infrastructure and trusted workforce support.

Why it matters

Everything essential. Nothing excessive.

Payroll, compliance, benefits, HR, risk, and workforce support are essential. The real question is whether they work together—or create more drag.

Sunnyside brings the infrastructure of employment into one coherent system, giving employers greater clarity, less friction, and fewer moving parts.

Capabilities

Calculated, filed, and reconciled across every jurisdiction where your people work.

Open enrollment, COBRA, ACA, qualifying events — handled end to end.

EEO, OSHA, state filings — tracked, prepared, submitted on time.

I-9, W-4, equipment, access — clean from day one to day done.

Documentation trails that hold up — no last-minute scrambles.

401(k), plan records, required notices, and related administration — kept on track.
