How Questco describes itself

Questco calls itself "a nationally recognized Certified Professional Employer Organization," and the IRS list backs the certification part: QUESTCO HR LLC holds active CPEO status as of the August 7, 2026 report. For federal payroll taxes on the wages it pays, QUESTCO HR LLC is the employer under 26 USC 3511, and a client switching in or out partway through a year carries its wage-base totals with it.

The rest of Questco's pitch is regional. It names Arizona and Nebraska, keeps separate phone lines for four states, and offers a franchise program. If your account would be handled by a franchise office, ask who you call when payroll goes wrong and how problems escalate to Questco itself.

States, licensing and where Questco fits

Questco lists no states, only the "Arizona to Nebraska and beyond" line and four regional phone numbers. Confirm in writing that it can co-employ staff in each of your states.

Licensing is the other check. Texas is the one to check first if you have staff there. Its Labor Code (chapter 91) bars anyone from offering PEO services in Texas without a license, and TDLR, the state licensing agency, keeps a searchable PEO license database. We did not search it for Questco, so do that before you sign. Arizona, Colorado and Nebraska each set their own rules.

What Questco might cost

Questco publishes nothing about its fee, and our research found no third-party estimate. Two published reference points help you judge a Questco number. Justworks charges $79 or $124 for each worksite employee every month, depending on the plan (checked October 16, 2026). ADP's cost article, last updated July 14, 2026, describes a market-wide span of $40 to $160 a month per employee, or 2% to 12% of total wages.

The fee is only one line. Workers' comp, health premiums and state unemployment tax come on top, and in our 10-person example health premiums alone were several times the fee; the PEO cost guide shows how to read each line, and 2026 SUTA rates lists the new-employer rate in Texas, Arizona, Colorado and Nebraska.

Benefits and workers' comp

Questco's site does not name health plans, carriers or a 401(k), so it scores 0 of 20 for benefits access. Renewals are the risk to price in. One ADP TotalSource client told Capterra (May 24, 2024) that "The second year our renewal went up 18%." Ask Questco which carriers it uses in your state and what its last two renewals looked like for companies your size.

The workers' comp model is not published either. Find out if Questco would cover your staff under its own policy, what each job class costs per $100 of wages, and whether audits happen at year end.

Questco reviews

Three public reviews in total: G2 shows 4.5 from 2 reviews and Trustpilot 3.2 from 1 (seen October 16, 2026). That is far too few to show a pattern, and we found no documented complaints. Ask Questco for references from clients in your state and industry.

Who Questco may suit, and alternatives

Questco may suit a small or midsize business in the Southwest or Plains states that wants a certified PEO with a regional presence. If you want more published detail to compare against, quote one or two of these:

• Justworks (67): posted per-employee prices and no setup fee.
• TriNet (50): published support hours and a stated fee structure.
• ADP TotalSource (44): workers' comp included in the service fee.
• Paychex PEO (34): HR business partner for clients under 10 employees.
• Insperity (33): service charge that does not rise with pay.
