Cross-system 401k reconciliation reports for HR teams

Payroll admins describe not being able to 'find all the info all together' and not knowing 'just what can be handled on the site for 401k, which restricts the necessary input capabilities for the payroll person to update personnel files.' The specific frustration isn't that the data doesn't exist — it's that it lives in two places with two logins and no combined view, so producing even a basic report of who contributes what requires manually exporting from both systems and doing VLOOKUP in Excel.

This gap is structural and unlikely to be fixed by ADP because their retirement product is often a resold or white-labeled third-party service. Integrating it deeply into Workforce Now would require a level of technical and contractual coordination that ADP has no short-term incentive to prioritize — especially since the current setup still generates support calls that, while frustrating, don't cause customers to churn immediately.

The buyer here is slightly different from the user: the CFO or finance director wants a clean monthly report showing 401k liability, match funding, and employee participation rates against the company's benefits budget. The payroll admin just wants to stop switching tabs. Neither of them can get what they need from either ADP portal alone.

This is a business because the reporting need recurs monthly (for finance), quarterly (for audits and board reporting), and annually (for plan testing and 5500 filings). A company that manually assembles this report every month is spending 2–4 hours of a payroll admin's time doing VLOOKUP work that could be eliminated entirely. At $30–50/hour fully loaded, that's real money — and the risk of a manual error on a 5500 filing is a separate and larger cost.

What to build

Build a scheduled report that connects to ADP Workforce Now payroll data and a 401k recordkeeper via API or structured CSV import, and delivers a monthly PDF and CSV to the HR admin and CFO showing per-employee contribution amounts, employer match funded, vesting status, and participation rate — formatted for both operational review and external audit handoff.

Where to start

Start with companies using ADP Workforce Now plus a single specific recordkeeper — Vanguard or Fidelity small business plans — where the export format is consistent enough that one solid parser covers a large enough initial market to get to 20 paying customers before you have to build the next integration.

The hard part

Getting reliable, structured data out of the 401k recordkeeper side is the hard part — each provider has a different export format or API, and building a parser that handles the ten most common ones without breaking on edge cases is months of unglamorous data engineering work before you can sell to a second customer.

How it makes money

Monthly subscription per company — $200–500/month depending on employee count — with a one-time $500 setup fee to map the plan structure and test the first reconciliation run.
