OnPay also says there is no fee for cancelling a pay run, and the per-employee fee applies only once per month.

OnPay says, "Get Your First Month Free," and also repeats that users can get one month free. The public pricing materials do not describe a longer trial period. The most explicit publicly disclosed promotional offer in the supplied documents is the first month free mention on the pricing page.
OnPay says there are no implementation or integration fees, and it also highlights free setup and data migration. The Help Center says you can expect free account setup and dedicated onboarding support. Based on the supplied documents, setup is included rather than sold as a separate charge.
The base fee includes payroll platform access, unlimited pay runs, tax filings and payments in all 50 states, payment methods like direct deposit, debit cards, or checks, employee online access, and live customer support. OnPay also states that many standard essentials, such as W-2s, 1099s, year-end filings, and multiple-state tax work, are included. The pricing model is designed to avoid surprise add-on charges for core payroll functions.
