How to Choose the Right Payroll Service (Step-by-Step Playbook)

1) Define Must-Haves vs Nice-to-Haves

• Core must-haves (non-negotiable):
  • Full-service tax filing (federal, state, local) + W-2/1099 e-file
  • Direct deposit, off-cycle payroll, garnishments
  • Multi-state support (if applicable) + new-hire reporting
  • Employee self-service (paystubs, tax forms, address/bank updates)
• Likely add-ons in the next 6–12 months:
  • Time & attendance, PTO policies, scheduling
  • Benefits admin (medical, 401(k)), COBRA
  • Basic HRIS (onboarding, docs, policies, org chart)
  • Integrations: accounting (QuickBooks/Xero), expense, ATS
• Compliance & security baseline:
  • SOC 2/ISO 27001, data encryption at rest/in transit
  • Audit trail, role-based access, disaster recovery posture
  • Clear SLA and error-resolution policy (tax-penalty handling)

Outcome: a one-page requirements list you can share with vendors.

2) Map Budget & Total Cost of Ownership (TCO)

• Typical pricing model: Base fee + per-employee/per-contractor + add-ons.
• Hidden cost checks: implementation fees, year-end W-2/1099 fees, per-run fees, multi-state surcharges, add-on minimums.
• Quick TCO formula (example):
  Company of 15 employees, base $40/mo + $6/emp + time tracking $3/emp:
  • Monthly = $40 + (15×$6) + (15×$3) = $40 + $90 + $45 = $175
  • Annual ≈ $2,100 (+ year-end forms if not included)
• Savings levers: annual prepay discount, bundling (payroll + time), partner/affiliate promos, implementation fee waivers.

Outcome: a realistic budget range with “walk-away” limit.

3) Build a Shortlist (2–4 Vendors) Aligned to Your Scenario

• Very small teams (1–10): Patriot, OnPay, Gusto (simple + affordable).
• SMBs scaling headcount (10–250): Gusto, Paylocity, ADP, Rippling.
• Accounting-centric: QuickBooks Payroll.
• US + international/contractors: Deel, Papaya Global.
• Complex multi-state or industry regs: ADP, Paylocity.

Outcome: 2–4 vendors that actually match your must-haves and budget.

4) Run Structured Demos (60–75 min each)

Use the same script for all vendors so comparisons are apples-to-apples.

Demo script checklist

1. Add a new employee (onboarding packet, e-sign, I-9/W-4).
2. Configure PTO policy and approvals.
3. Import time or run a pay cycle (incl. bonus/off-cycle).
4. Multi-state scenario: add a second state and run payroll.
5. Generate W-2/1099 and year-end checklist.
6. Correct a mistake: retro pay adjustment and tax amendment flow.
7. Reports: payroll summary, GL export, labor distribution.
8. Mobile self-service: show employee view.
9. Admin controls: roles, permissions, audit trail.
10. Support experience: hours, channels, typical first-response time.

Capture evidence (screenshots/notes) for each step.

5) Score with a Decision Matrix (weight by importance)

Assign weights that reflect your business; example below.

Suggested weights

• Compliance & tax automation – 25%
• Usability & onboarding – 20%
• Add-ons & integrations – 15%
• Pricing/TCO – 20%
• Support & SLAs – 10%
• Reporting & analytics – 10%

Score each vendor 1–5 per category, multiply by weight, sum totals.

Outcome: a defensible, numeric decision—great for leadership sign-off.

Red Flags to Watch For

• Year-end forms not included or priced per form at premium.
• Vague multi-state support; “we’ll handle it manually.”
• No written commitment on tax-penalty liability.
• Proprietary lock-in with expensive exit/export fees.
• Support only via email with slow SLAs.

FAQ: Best Payroll Companies in the USA (Small Business)

What is the best payroll company for small businesses in the USA?
It depends on your needs. For all-in-one simplicity, many SMBs like Gusto. For deeper HCM, Paylocity or ADP fit better. QuickBooks Payroll suits firms already on QuickBooks; Deel/Papaya help if you also pay abroad.

How much do payroll services cost in the U.S.?
Most follow a base fee + per-employee model, with add-ons (time, benefits, HR) priced separately. Ask vendors for transparent itemization and any annual discounts.

Can very small teams (1–5 people) use a payroll company?
Yes. Solutions like Patriot or OnPay are popular for micro-teams, and they can scale as you hire.

Do payroll providers handle taxes automatically?
Full-service plans typically file and remit federal, state, and local payroll taxes and generate W-2/1099 filings.

What if we have contractors or international hires?
Look at providers with contractor payments and global options—e.g., Deel or Papaya Global.
