The moment that drives this: an HR manager at a 40-person company has just gotten an ADP TotalSource quote, described internally as 'not a cheap date,' and suspects they're being sold a product sized for a 500-person company. They need to find alternatives but don't know how to evaluate them on the specific dimensions that burned them last time — transparent per-employee pricing, no module upsell traps, compliance coverage that matches their state footprint, no early termination penalties.
This gap exists because the market for payroll vendor comparison is dominated by content that is either affiliate-driven (review sites get paid when you click through to sign up) or generalist (covering features that matter to enterprise buyers, not the specific cost-structure traps that hurt small companies). No one has built a comparison experience anchored specifically to the cost complaints that small HR teams actually have: what does it cost per employee per month all-in, what are the exit terms, what compliance modules are included vs. billed separately.
The complaints are direct: ADP is 'too expensive for a small company which doesn't use all the benefits,' the fees for the pay card are a surprise, reports cost extra, and companies end up 'not utilizing ADP to its fullest capability because of pricing.' A small company doesn't need a feature matrix — they need to know the true monthly cost for their headcount, what happens if they leave, and whether compliance training for their states is included or an add-on.
This is a recurring business because companies grow, renegotiate, and switch vendors on 2-4 year cycles. The HR manager who used this at 40 employees comes back at 120. And because the buyer (HR Director or founder) makes this decision rarely and under time pressure, they'll pay for a shortlist they trust over one more blog post they have to second-guess.
What to build
Build a guided questionnaire that collects headcount, states of operation, required compliance modules, and budget range, then generates a side-by-side true-cost comparison for 4-6 payroll vendors — showing all-in per-employee monthly cost at their specific size, early termination terms, and which compliance training modules are included vs. billed as add-ons — based on actual vendor pricing collected and verified quarterly.
Where to start
Start with companies that post in HR communities (Reddit's r/humanresources, HR Facebook groups) saying they're leaving ADP — they're at peak motivation, have a real contract to compare against, and will tell you exactly what went wrong, which is the seed data for accurate vendor profiles.
The hard part
Payroll vendor pricing is intentionally quote-based and changes by headcount, state, and negotiation — maintaining accurate, verified pricing data across 6+ vendors quarterly requires either direct vendor relationships (which create affiliate incentive conflicts) or a continuous data collection process from real customer invoices.
How it makes money
Free shortlist for companies under 50 employees (drives data collection and word of mouth), paid detailed vendor reports for companies 50-500 employees at a flat one-time fee ($150-400), with optional vendor-paid placement for verified non-affiliate listings.
