Payroll software rarely gets chosen for its feature list. It gets chosen because someone finally got tired of running payroll by hand, or because the current vendor botched a tax filing badly enough that finance started shopping around. Gusto, ADP, and Rippling all solve the same core problem, paying people correctly and on time while staying compliant with tax law, but they're built for different company sizes and different tolerances for complexity.
Gusto: payroll that doesn't feel like enterprise software
Gusto is the platform startups and small teams graduate to once spreadsheets and a part-time bookkeeper stop working. Pricing is straightforward: Simple runs $40/month plus $6 per person, Plus is $60/month plus $9 per person, and Premium drops into a custom quote once a company needs dedicated support and compliance alerts.
What that buys is full-service payroll with federal and state tax filings handled automatically, direct deposit, contractor payments as a $6/month add-on, and W-2/1099 generation that doesn't require a separate accountant scramble every January. Benefits administration plugs into the major insurance carriers, and new-hire onboarding walks employees through I-9 and W-4 collection without HR chasing paperwork by email.
The tradeoffs show up once a company outgrows "small." The HRIS side is functional but not deep. There's no real org chart tooling, no performance review workflow worth mentioning, and the built-in applicant tracking system is closer to a placeholder than something a recruiting team would choose on its own. Gusto is also US-only. If a hire ever lands outside the US, this stops being an option entirely. And per-person pricing adds up faster than the sticker price suggests: a 40-person company on Plus pays $60 plus $360 in per-person fees, or $420/month, before any add-ons.
ADP: the incumbent that processes 1 in 6 US paychecks
ADP's pitch is scale and reliability. Roughly one in six US workers gets paid through an ADP system, a number that reflects decades of tax compliance work across all 50 states rather than clever marketing. Three products cover different company sizes: RUN Powered by ADP for small business, starting at $79/month plus $4/employee, Workforce Now for mid-market, and Vantage HCM for enterprise. The latter two run on custom quotes rather than published pricing.
Tax and compliance depth is where ADP earns its reputation. Multinational payroll, through ADP GlobalView and Celergo, is among the most mature options available for large companies operating across borders. Workers' comp and benefits integrate with the major carriers without the gaps smaller vendors sometimes have when a claim gets complicated.
The complaints, and they come up constantly in r/humanresources threads, center on the interface. Workforce Now and Vantage HCM both look and feel like software built for a different decade. Support quality depends heavily on account size: enterprise clients get a dedicated rep, smaller accounts get routed through a call center with inconsistent response times, especially during tax season when volume spikes. Pricing also isn't transparent past the entry tier, and getting out of an ADP contract once a company is locked in has a reputation for real friction.
Rippling: one employee record, everything else follows
Rippling's core idea is that hiring someone should trigger one workflow, not five separate logins into five separate systems. Add a new employee and Rippling can provision their laptop, create their Google Workspace account, add them to the right Slack channels, start benefits enrollment, and run their first paycheck, all from a single onboarding trigger. It sounds like a line from a sales deck until a team actually configures it and finds out the integrations are real.
Pricing starts at $8/user/month for the core platform, but that's just the base. Payroll, benefits, device management (MDM), and IT automation are all separate add-ons, and a full deployment covering HR, IT, and finance typically lands at $15 to $25 or more per user per month. Global payroll covers more than 50 countries, though it isn't as refined as a specialist like Deel for complicated multi-country setups involving contractor conversions or local benefits law.
The catch is that the same modularity making Rippling powerful also makes the final bill unpredictable. What starts as "$8/user" turns into a quote that depends on exactly which modules get switched on, and that number isn't published anywhere; someone has to talk to sales to get it. Initial setup takes real time to configure correctly, and because no single module is as deep as a dedicated tool, Greenhouse still beats Rippling's applicant tracking and Jamf still beats its device management. It's also a younger company than ADP, with a shorter track record at the scale ADP has operated at for decades.
What actually breaks in practice
Payroll problems rarely show up as dramatic outages. They show up as a state tax filing that got flagged three months late, a contractor who was misclassified as a W-2 employee for two pay cycles, or a benefits enrollment window that closed before HR noticed. Gusto's smaller feature surface means fewer places for this kind of error to hide, but it also means less automated cross-checking between modules. ADP's scale gives it more built-in compliance guardrails, at the cost of a support queue that can take days to resolve a real error during peak season. Rippling's single employee record is the strongest defense against data getting out of sync between HR and IT, but a misconfigured workflow during setup can cascade: get someone's employment type wrong at onboarding and it can quietly break their benefits eligibility, their device provisioning, and their payroll classification all at once.
Switching providers mid-year is its own kind of pain regardless of which one a company picks. Payroll history has to transfer cleanly, tax IDs have to re-register with the new provider in every state, and most companies find the safest window to switch is right at a calendar year boundary, not mid-quarter.
Real numbers, side by side
Here's what two different company sizes actually pay, using self-service or the base entry tier for each:
A 10-person startup:
- ▸Gusto Simple: $40 + ($6 × 10) = $100/month, or $1,200/year
- ▸ADP RUN: $79 + ($4 × 10) = $119/month
- ▸Rippling core: $8 × 10 = $80/month, before payroll and benefits add-ons push it toward $200-300/month for a real deployment
A 40-person company:
- ▸Gusto Plus: $60 + ($9 × 40) = $420/month, or $5,040/year
- ▸ADP RUN: $79 + ($4 × 40) = $239/month at the base tier, though most companies this size need add-ons that push it closer to $300-400/month
- ▸Rippling: $8 × 40 = $320/month for the core platform alone; add payroll and benefits and a realistic deployment runs $600-1,000/month for the same headcount
Gusto is the cheapest full payroll solution for a company that only needs payroll and light HR. Rippling costs more but can replace separate IT and device management subscriptions that would otherwise be a second line item. ADP sits in the middle on price but wins on compliance depth once a company operates across multiple states or is preparing for an eventual acquisition, where buyers and auditors tend to prefer an established payroll vendor already in the stack.
Which one to actually pick
Pick Gusto if the company is US-only, under 100 employees, and the goal is clean payroll plus basic HR without paying for features that won't get used. It's the fastest to set up and the interface doesn't require training.
Pick ADP if the company needs multi-state or international compliance depth, is already large enough that a dedicated account rep matters, or is heading toward an acquisition where buyers expect to see an established payroll vendor in the stack. Budget real time for onboarding and don't expect the interface to feel modern.
Pick Rippling if the company is already juggling separate HR, IT, and device management tools and the actual win is consolidation, not just payroll. The per-user math only works out if multiple modules get used; buying Rippling for payroll alone at $15-25/user/month is the expensive way to run payroll.
None of these three is the wrong answer on its own. They're built around different definitions of what a company needs payroll software to actually do beyond paying people on time.
