Payroll Services

Run payroll across every state, every pay frequency, every benefit — without a payroll admin.

How it works

EFTPS federal deposits, state payroll taxes, EDI 834 benefits feeds — all calculated from gross-to-net and submitted on the right schedule, every cycle. Multi-state nexus tracked continuously.

Garnishments, 401(k) contributions, ACA 1094-C/1095-C, W-2s — all generated automatically from the same time and pay data. Funding initiates from your operating account, calibrated to ACH settlement.

Three pillars

Payroll, taxes, and benefits — wired together.

A payroll platform that handles the compliance burden so finance teams stop reconciling exports.

1

Tax Deposits & Filings

EFTPS federal deposits on the correct schedule — monthly, semi-weekly, or next-day rule. State payroll tax remittance across every operating state. ACA 1094-C/1095-C, W-2, and 5500 prep generated automatically from payroll data already in the system.

2

Benefits & 401k Feeds

EDI 834 enrollment feeds dispatch directly to health, dental, vision, and 401k carriers. New hires, terminations, and benefit elections flow without manual file exports. FSA/HSA contribution and election management included.

3

Funded From Your Bank

Payroll funding initiates automatically from your business banking account, calibrated to ACH settlement dates. Net pay disburses on schedule. Every dollar reconciles to the GL the moment it moves.

Agents in action

Live orchestration

Every cycle, end-to-end

A payroll run triggers tax-deposit calculation, benefits feeds, and funding agents that resolve in parallel — taxes filed, carriers updated, net pay disbursed.
