The 7-step decision framework
Define your must-haves
Use the requirements checklist above. Be specific: payroll in California and Texas, multi-state expansion expected within 12 months, performance reviews twice a year. Avoid vague requirements.
Set your budget
Multiply (current employees + projected hires in 12 months) by $10-$15 per employee per month for a baseline budget. Add a $50/month base fee buffer. That gives you a realistic range. Anything significantly cheaper means thin features; anything significantly more expensive should be PEO-grade or include real add-on value.
Shortlist 3 platforms
Use this site and others to identify 3 platforms that match your stage and needs. Resist the urge to evaluate 8 - decision fatigue kills the process. For most small businesses the shortlist is some combination of: Gusto, BambooHR, Rippling, OnPay, Justworks.
Run free trials
Sign up for the trial on every shortlisted platform that offers one. Walk through onboarding a fake employee, running a fake pay cycle, and generating a report. This takes 2-3 hours per platform but is the single highest-leverage step.
Get all-in pricing in writing
For quote-based platforms, request the all-in monthly cost in writing including all add-ons you'll need (payroll, time tracking, benefits admin). Have them confirm the renewal pricing policy. Verbal quotes mean nothing.
Check references and reviews
Ask the vendor for 2-3 customer references at your team size. Read 20+ G2 and Capterra reviews focused on the issues you'll actually hit (support quality, billing surprises, exit experience). Discount the marketing-heavy reviews.
Decide and document the decision
Write a one-page decision memo: why you picked this platform, what trade-offs you accepted, what the success criteria are at 6 and 12 months. This makes future decisions easier and surfaces poor-fit signs faster if they emerge.
Five red flags during evaluation
If a vendor refuses to share pricing without a discovery call, you're paying a premium that other customers - the ones with negotiating power - are not paying. Walk away or budget for hard negotiation.
Locks you in before you've validated fit. Even mid-market vendors should offer a monthly option, even at a small premium. Annual-only is a vendor protecting itself, not you.
Common with ADP and Paychex. Adds $200-$500 per year for a 25-person team. Modern competitors include forms in the standard price.
If the vendor cannot show you exactly how to export employee records, payroll history, and benefits data, assume the migration will be painful. Transparency about exit means confidence in the product.
Especially common from PEOs that don't operate in all 50 states. Ask explicitly: ‘Can you support an employee in Wyoming starting next month?’ If the answer is anything other than yes or a clear timeline, it's a problem.
If you ask ‘does this integrate with QuickBooks Online for journal entries?’ and the rep says ‘we have an integration marketplace’ without specifics, the integration is probably weak. Get specific Yes or No answers.
