Gusto vs. ADP RUN: which payroll system fits your company?
Gusto publishes monthly prices and includes unlimited payroll runs. RUN Powered by ADP packages payroll with progressively broader hiring and HR services but requires a tailored quote. The right comparison is not brand familiarity—it is the complete cost and control model for every payroll the company actually runs.
Choose the pricing and service model you can control.
Evaluate Gusto first when the company wants transparent monthly prices, unlimited regular and off-cycle payroll runs, straightforward online purchasing, and payroll, benefits, time, and HR tools in one small-business platform.
Evaluate ADP RUN first when the company wants four quote-based service tiers, 24/7 payroll support, ADP's broader small-business ecosystem, or specific capabilities such as multi-company management, job costing, garnishment payment, unemployment-insurance management, and deeper HR support.
Do not compare only the monthly headline. Normalize payroll frequency, off-cycle runs, year-end forms, tax registrations, time, HR, benefits, implementation, support, accounting work, discounts, and renewal pricing.

1. Price every payroll—not just a normal month
Gusto currently publishes Simple at $49 per month plus $6 per person, Plus at $80 plus $12 per person, and Premium at $180 plus $22 per person. Every plan includes unlimited payroll runs. Simple centers on basic single-state payroll; Plus adds multistate payroll, time tracking, scheduling, and next-day pay; Premium adds enhanced support, HR guidance, business-compliance tools, same-day and instant-pay options, and project-based rules and costing.
ADP presents Essential, Enhanced, Complete, and HR Pro RUN packages but requires a quote. ADP's own pricing-transparency guidance says a specialist builds a tailored proposal. The quote should identify what triggers a fee: base account, payroll runs, paid employees, additional jurisdictions, W-2s and 1099s, delivery, additional companies, tax services, time, HR, retirement, benefits, workers' compensation, implementation, and support.
| 20-person example | Published monthly platform price | Published annual platform price |
|---|---|---|
| Gusto Simple | $169 | $2,028 |
| Gusto Plus | $320 | $3,840 |
| Gusto Premium | $620 | $7,440 |
| ADP RUN | Obtain a written quote | Normalize every recurring and event-driven fee |
The Gusto figures use regular published platform prices, not promotions. They exclude benefits premiums, workers' compensation, broker integration, priority support, state registrations, tax credits, mailing, optional services, and internal labor. Ask ADP for both promotional and post-promotion pricing, then compare year-one and year-two cost.
2. Match the package to the payroll cases you actually run
Both systems cover the familiar payroll path, but an evaluation should emphasize exceptions. Build a sample containing salaried and hourly employees, overtime, shift or project pay, bonus and commission, reimbursement, benefit deductions, retirement, garnishment, paid leave, contractor payment, new hire, termination, retroactive change, void, correction, and off-cycle payroll.
Gusto's unlimited-run model is economically clear for bonuses, corrections, and ad hoc payrolls, although funding speed and specific plan capabilities still vary. ADP RUN supports online, phone, and mobile payroll, recurring automation through RUN & Done, multi-jurisdiction payroll, and additional services by package. Require ADP to mark which test cases are included and which create separate charges or manual service requests.
Time each workflow. Count manual inputs, approvals, error warnings, support contacts, corrections, and accounting adjustments. A low quoted rate is not cheaper when finance or the owner spends hours repairing each payroll.
3. Map tax responsibility by jurisdiction
Gusto includes payroll tax filings and payments in its published plans and says it files federal, state, and local payroll taxes. ADP says RUN deducts and files federal, state, and local payroll taxes and creates and e-files W-2 and 1099 forms. Neither statement eliminates the employer's need for accurate data, registrations, agency access, and reconciliation.
Create a matrix for every work and home location: withholding, unemployment, local tax, paid leave, disability, reciprocity, registration status, deposit schedule, tax rate, account number, and notice owner. Ask who registers a new state, updates rates, files amendments, answers notices, fixes prior-provider errors, and pays penalties when either the provider or company supplied incorrect information.
Run a new-state employee, employee move, local-tax change, off-cycle bonus, termination, taxable fringe benefit, and prior-quarter correction. Preserve filings, payment confirmations, agency correspondence, and year-end forms outside the payroll platform.
4. Compare HR, time, benefits, and support as complete bundles
Gusto brings payroll together with health benefits, retirement, workers' compensation, time, PTO, hiring, onboarding, and employee management. Published package scope matters: time tracking and scheduling begin with Plus, while Premium adds HR guidance, compliance tools, and a dedicated account partner. Eligible companies may integrate an existing benefits broker for an additional fee.
ADP RUN's package ladder begins with payroll and expands into ZipRecruiter, state-unemployment and garnishment services, basic HR support, enhanced HR support, and employee programs. ADP also offers time, retirement, insurance, workers' compensation, and benefits services around the payroll platform. The exact combination and fee belong in the proposal.
Identify every existing vendor and internal task that a package would replace. Then test employee onboarding, I-9, benefits deductions, time approval, PTO, garnishment, unemployment claim, handbook or HR question, and termination. Record whether the provider supplies software, administration, advice, brokerage, insurance, or only an integration; those are different services.
5. Protect accounting, approvals, and cash forecasting
Test the journal for wages, employer taxes, employee deductions, benefits, retirement, reimbursements, garnishments, contractors, departments, locations, classes, projects, clearing accounts, and cash. Confirm whether the accounting connection sends summarized or employee-level detail, how dimensions map, and how corrections change a previously posted journal.
Finance should be able to reconcile gross-to-net payroll, tax liabilities, benefit deductions, payroll-provider fees, and every bank withdrawal. Require a funding calendar showing approval cutoffs, withdrawal dates, direct-deposit timing, tax debits, returned payments, corrections, and holiday changes. Put those dates into the cash forecast.
Review permissions for bank changes, employee data, pay rates, deductions, payroll approval, reports, and integrations. Use separate preparer and approver roles where headcount permits. Ask how both systems authenticate administrators, record audit history, notify owners of critical changes, and revoke access after termination.
6. Plan the migration around year-to-date integrity
Export employees, earnings codes, deductions, tax accounts and rates, direct-deposit authorizations, garnishments, PTO, benefits, retirement, workers' compensation, payroll history, filings, notices, and general-ledger mappings. Reconcile year-to-date wages and taxes by employee and jurisdiction before the first live payroll.
Run at least one parallel calculation using the same hours and changes. Compare gross pay, every deduction, employee and employer taxes, net pay, cash requirement, journal, and filing liability. Resolve differences before funding. Confirm who files the final prior-provider returns and year-end forms, especially during a midyear migration.
Communicate employee actions and effective dates without exposing sensitive payroll data. Retain prior-system reports for the required record period and document access after termination. Do not cancel benefits, workers' compensation, retirement, or tax services until replacement coverage and responsibilities are confirmed.
Run this payroll selection process
- Build one workforce census. Include employee types, states, pay frequencies, earnings, benefits, deductions, time, contractors, and projected growth.
- Normalize two years of cost. Separate base, people, payroll runs, forms, tax services, time, HR, benefits, implementation, discounts, and renewal.
- Run exception payroll. Test hourly, overtime, bonus, commission, reimbursement, garnishment, leave, correction, contractor, and termination cases.
- Test every jurisdiction. Add a state, move an employee, change a local tax, amend a filing, and route an agency notice.
- Reconcile the close. Tie registers, filings, liabilities, deductions, provider fees, bank withdrawals, and journals to the ledger.
- Challenge support. Submit tax, payroll, integration, HR, and urgent funding questions through the channels included in the proposed package.
- Verify controls. Review roles, approvals, authentication, bank-change protection, audit trails, exports, and former-employee access.
- Plan cutover. Reconcile year-to-date balances, parallel-test payroll, confirm filings and coverage, communicate changes, and preserve records.
Recommendation by operating profile
Lean, price-transparent team
You value published pricing, unlimited payroll runs, online purchasing, and an integrated small-business experience for payroll, benefits, time, and HR.
Service- and support-oriented team
You want 24/7 payroll support, four service tiers, ADP's wider ecosystem, or specific multi-company, job-costing, garnishment, unemployment, or HR services.
Multistate or exception-heavy payroll
Your choice depends on tax jurisdictions, pay frequencies, off-cycle runs, HR service, accounting detail, or migration complexity more than a generic product winner.
Separate payroll software from broader employment models.
Compare Gusto vs. Rippling when a wider HR and IT platform matters, QuickBooks Payroll vs. Gusto when accounting integration drives the shortlist, or Gusto vs. Justworks when a PEO may replace payroll-only software.

Frequently asked questions
Is Gusto or ADP RUN better for a small business?
Gusto is usually the more direct first evaluation when transparent monthly pricing, unlimited payroll runs, online setup, and integrated payroll, benefits, and HR tools are priorities. RUN Powered by ADP deserves the first evaluation when the company values ADP's small-business payroll infrastructure, quote-based packages, 24/7 support, multi-company or job-costing capabilities, or a possible path into ADP's broader product family. The final answer should come from a written quote and test payroll.
How much does Gusto cost for 20 employees?
At current regular published prices, Gusto Simple is $169 per month, Plus is $320, and Premium is $620 for 20 paid people. That equals $2,028, $3,840, and $7,440 per year. These calculations exclude promotions, benefits premiums, workers' compensation, broker integration, priority support, state registrations, tax services, and other add-ons. ADP RUN requires a tailored quote.
Does ADP RUN publish pricing?
ADP presents four RUN packages—Essential, Enhanced, Complete and HR Pro—but directs buyers to request pricing. Its pricing-transparency guidance says a small-business payroll specialist builds a tailored proposal. Require the proposal to identify base fees, payroll-run fees, employee charges, year-end forms, implementation, tax services, add-ons, discounts, renewal pricing, and off-cycle runs.
Do Gusto and ADP RUN file payroll taxes?
Both advertise payroll-tax calculation, filing, and payment services. Gusto includes tax filings and payments in its published plans. ADP says RUN deducts and files federal, state, and local payroll taxes and prepares and e-files W-2 and 1099 forms. Buyers should still map every jurisdiction, registration, notice, amendment, correction, and penalty responsibility in writing.
Can a company switch payroll providers during the year?
Yes, but a midyear change requires careful transfer and reconciliation of year-to-date wages, taxes, deductions, benefits, garnishments, leave, retirement, workers' compensation, and employee records. A quarter or year boundary may simplify reconciliation, but accurate balances, agency accounts, coverage dates, final filings, and a parallel payroll matter more than the calendar date.
Method and limitations
This guide compares official public US product, pricing, package, and support information reviewed on October 6, 2026. ADP does not publish a standard RUN price list, so no unsupported ADP price estimate is presented. The analysis does not rely on vendor payment, private demonstrations, customer-review averages, or claimed hands-on experience. Payroll has tax, employment, benefits, and insurance consequences beyond software selection. Validate requirements using company data, qualified advisers, current proposals, service agreements, and test payrolls.
