The moment comes during month-end close or a benefits audit: the HR manager needs a headcount-by-department report with YTD pay, opens ADP's report builder, gets lost in 400+ field options, and either gives up or submits a support ticket knowing the answer is weeks away. This gap persists because ADP has a structural incentive to keep reporting inside its own walls — every custom report they build for a fee is revenue, and making self-service too easy cannibalizes that line. The buyer of ADP (usually a CFO or HR director) signs the contract, but the daily user (a payroll specialist or HR generalist) is the one suffering, and their complaints rarely surface loudly enough to break a multi-year contract.

The specific complaints are concrete: reports that list one employee on two lines when they worked in two departments, requiring manual YTD addition; quarterly detail reports that aren't available online at all and require a phone call plus a 2-3 week wait; and system updates that silently undo field mappings so that a report that worked last week fails during payroll processing. These aren't edge cases — they're the weekly rhythm of an HR admin's job.

What makes this a recurring business rather than a one-time fix is the churn inside HR teams. Every time a new payroll coordinator joins, they have to re-learn which of the hundreds of report templates actually work and how to interpret the output. Institutional knowledge about which canned reports are broken gets lost. The need to rebuild, retrain, and re-validate reports recurs constantly — and every quarter brings new compliance needs (ACA, 401k census, workers' comp) that require fresh output nobody taught them to pull.

What to build

Connect to ADP Workforce Now via its API, pull the raw employee, payroll, and benefits data, and present it through a report builder with no more than 30 pre-mapped, labeled fields — grouped by use case (payroll audit, headcount, benefits census) — that exports clean CSVs and Excel files without requiring the user to understand ADP's internal field naming conventions.

Where to start

Start with the single most-requested report type that ADP handles worst: the multi-department employee YTD pay summary, which currently forces manual line-by-line addition — build exactly that one report, perfectly, and use it as the lead demo for every HR admin who has complained about it publicly on G2 or Capterra.

The hard part

ADP's API access varies by contract tier, and smaller customers on older agreements may not have the API access needed to pull data programmatically — meaning the first customer conversations will quickly surface who can actually use it and who needs a manual export workaround that degrades the product significantly.

How it makes money

Monthly subscription per ADP instance (not per seat), priced at a fraction of what ADP charges to build a single custom report — likely $149-$399/month depending on employee count, with the first custom report template included in onboarding.
