Gusto vs. OnPay: An Overview

Gusto vs. OnPay Pricing & Hidden Costs

Gusto uses a tiered pricing model with multiple plans that scale from basic payroll to full-service HR, each with a base fee plus a per-employee cost. While core payroll features are included, many advanced tools—like performance management, HR resources, or faster payroll options—come as paid add-ons, which can increase your total cost over time.

OnPay, by contrast, keeps pricing straightforward with a single base plan plus a per worker cost, covering full-service payroll, tax filings, benefits administration, and integrations. Most essentials are included with no hidden fees, though optional add-ons like HR tools or compliance support come at an extra monthly cost. 

To choose the right vendor, look beyond the headline price and map each tool’s features to your actual payroll and HR needs. Consider how your business might grow, which features you’ll use most, and whether you’ll need add-ons like benefits management or advanced reporting. Running real-world cost scenarios can help you determine which platform delivers better long-term value—not just the lowest starting price.
