G&A Partners is a privately held, independent PEO founded in 1995, with roughly 130,000 worksite employees after its January 2026 acquisition of Ethan Allen HR Services. It is IRS-certified and ESAC-accredited, prices per employee per month rather than as a percentage of payroll, and quotes that fee per client rather than publishing it. Its core is the mid-market: roughly 5 to 250 employees, sweet spot 50 to 200, concentrated in Texas and the Sun Belt and now reaching into the Northeast.
The model is service-led. G&A sells dedicated account management and HR consultants rather than a call center, which in complex compliance environments is usually the reason companies sign. Buyers shop alternatives for a short list of reasons: hand-offs that got slower than the dedicated-team promise implied, a renewal that moved faster than payroll, growth or an acquisition that pushed the company outside G&A's strongest regions, or a CFO who wants reporting the platform does not deliver.
Here are the providers most often shortlisted against G&A, and when the right answer is to stay put.

6 of the 6 providers here do not publish rates. What varies between them is the fee structure, not a published number, so compare the structures in the fourth column and get quotes for the rest. Fit, exclusions and credentials come from each provider’s profile in our directory, verified September 2026 against the IRS CPEO list and the ESAC directory. Typical cost is a published or publicly reported range, not a quote.
How we picked these. The providers below were chosen from the 36 PEOs on our panel by fit with the typical G&A Partners client: company size (5 to 250 employees (sweet spot: 50 to 200)), industries (Professional Services, Healthcare, Finance) and the trade-off in G&A Partners’s own profile (mixed third-party review scores (yelp ~2.8/5; bbb complaints around departmental hand-offs); service experience reportedly varies). Credential status comes from the IRS CPEO register and the ESAC directory, verified September 2026. We are paid by the PEO a client selects, from any provider on the panel, at no cost to the client, so no provider pays more to appear here.
Questco
Questco is the closest like-for-like peer to G&A in the Texas mid-market. Founded in 1989, based in The Woodlands, privately held and independent, it serves roughly 10 to 250 employee companies and sells what G&A sells: personalized service from people who know your business, in Houston, DFW, Austin and San Antonio.
Where it wins is local depth. The Texas relationships are real rather than a talking point, and Questco has been recognized by the Houston Business Journal as a Best Place to Work. Pricing is quote-only, but it competes in the same territory G&A occupies.
Where it loses is credentials and reach. Questco is CPEO-certified, covering the federal employment tax question, but it is not ESAC-accredited, and G&A carries both. That gap is invisible to most buyers and decisive to a few. Questco is also more regionally concentrated, so a company expanding beyond the Sun Belt is moving the wrong way. Treat the benefits stack as a peer, not an upgrade.
Insperity
Insperity is the upgrade option: publicly traded, founded in 1986, around 312,000 worksite employees, and roughly 90 regional offices staffed with named HR specialists. Both are CPEO and ESAC, both target the same 25 to 500 employee mid-market, and both have deep Texas roots. The difference is how much service you get and what you pay for it.
Where Insperity wins is advisory depth and predictability. The dedicated HR business partner model is the most structured version of what G&A sells, the regional footprint puts named people behind the account, and the training and risk tools are better developed. If hand-offs are why you are leaving, Insperity is built to answer that.
Where G&A wins is structure. Neither publishes a rate, so get both quoted on the same census and compare the administrative fee, medical rates and workers' comp separately; Insperity's fee carries the dedicated HR business partner, and that only pencils if you consume the consulting. Insperity contracts also tend to run long with strict exit terms, where G&A works on annual agreements. Insperity's Q4 2025 results flagged elevated healthcare claims and pricing pressure, worth raising in a renewal conversation. Our Insperity review goes deeper on where the premium earns out.
CoAdvantage
CoAdvantage is to the Southeast roughly what G&A is to Texas: a privately held CPEO and ESAC-accredited PEO founded in 1997, about 110,000 worksite employees, focused on 10 to 250 employee companies. It merged with PrimePay in June 2025 under Aquiline Capital, pairing its CoAdQuantum platform with PrimePay's HCM stack.
Where it wins is workers comp and price. Its pooling and risk management are a real strength, and for a company with meaningful comp exposure the premium difference alone can carry the decision. Pricing is PEPM, quoted per client, and its site says it does not publish a fixed rate; implementation has a reputation for being straightforward. If your center of gravity has shifted to Florida, Georgia or the Carolinas, it has regional density G&A is still building.
Where G&A wins is stability and consulting depth right now. The PrimePay integration is in early innings, with the product roadmap and rep coverage unsettled through 2026, which is the last thing you want to buy into if you are leaving because of service inconsistency. CoAdvantage also carries fewer carrier options and a thinner consulting bench. Ask about service-team continuity and get roadmap commitments in writing.
Vensure Employer Solutions
Vensure is a different animal. Founded in 2004, backed by Stone Point Capital and assembled through more than 100 acquisitions, it is the largest private PEO group in the country by worksite employees at roughly 526,000. It is CPEO and ESAC, prices PEPM or as a percentage of payroll, quoted per client and varying by legacy brand, and serves 10 to 500 employee companies.
Where it wins is risk appetite and vertical depth. Construction, staffing, restaurants, manufacturing and nonprofits are core business, and it writes industries several SMB-focused PEOs decline. The vertical knowledge inherited from acquired brands is real: construction comp classification, staffing-firm tax complexity and restaurant tip-credit handling are understood rather than learned on your account, and scale produces decent benefits buying power.
Where G&A wins is consistency. Vensure's service experience varies by which acquired brand delivers your account, and integration across the group is uneven. G&A's model, whatever its frictions, is at least one organization. If you do quote Vensure, ask early which operating brand services the account and what the escalation path looks like.
Paychex PEO
Paychex PEO is the national infrastructure play. Part of publicly traded Paychex, with a PEO arm that now includes the former Oasis business, it is CPEO and ESAC, serves 5 to 500 employees, and prices PEPM or as a percentage of payroll, quoted per client.
Where it wins is multi-state payroll and tax compliance, among the deepest in the industry. If you have drifted into ten states with a seasonal or variable workforce, that machinery is worth more than a consultative HR relationship, and if you already run Paychex payroll, implementation friction drops.
Where G&A wins is service depth. Paychex delivers through a pooled service center, and deep HR consulting is not what the model is built for. Add-on fees make a full fee schedule mandatory before signing, regional pricing variation is wide, and 2025 to 2026 investor commentary flagged the PEO segment as underperforming relative to the wider business. Paychex is right for a multi-state employer that values payroll certainty over consulting, and wrong for a company leaving G&A because it wants more attention, not less.

Other PEOs worth considering
Engage PEO
CPEO and ESAC, operating in all 50 states and serving mid-market companies of 25 to 500 employees. Its distinguishing feature is licensed employment-law attorneys on staff paired with every client, unusual at this tier and valuable if your exposure is genuinely legal. Pricing is quote-only and there is no mobile app. See the Engage PEO profile.
PrestigePEO
A Long Island-based CPEO and ESAC PEO founded in 1998, focused on Northeast and Mid-Atlantic companies of 10 to 100 employees, with a high-touch model and strength in professional services and skilled trades. Relevant if your center of gravity has moved to the Northeast, the territory G&A entered through the Ethan Allen acquisition.
Who should not leave G&A Partners
G&A Partners is built for mid-market companies (25 to 500 employees), companies wanting personalized service teams, texas and sun belt-based businesses, complex compliance environments. Its published sweet spot is 5 to 250 employees (sweet spot: 50 to 200) and it writes professional services, healthcare, finance, technology, manufacturing, construction. If your company sits inside all three of those, the case for moving has to come from price or service, not from fit, because on fit you are already in the right place. Three specific reasons to stay:
- Personalized service teams, not call center support
- Strong compliance and HR consulting depth
- Good mid-market pricing
If none of those three describes why you bought G&A Partners, that is the real signal, and the providers above are where to look. G&A Partners's own profile says it is not the right fit for: companies outside g&a's core service regions; very small companies under 15 employees; companies wanting a tech-first platform.
When the timing is wrong to switch from G&A Partners
Leaving is a good idea only when the math is clearly better on the other side and the disruption is justified. Several situations argue for staying put.
You are mid-contract. G&A works on annual contracts with reasonable exit terms, which is a genuine advantage, but reasonable is not free. Read the termination section, notice period and transition language before you take a sales call.
You are mid-plan-year. Switching mid-year means a W-2 split, two sets of tax filings, a 401(k) blackout, a benefits re-enrollment cycle in the middle of the year and a COBRA handoff. If your renewal is more than four months out, plan the switch for the renewal.
You are hiring hard or integrating an acquisition. Doing either while changing PEOs compounds the risk. Lock the workforce, then change the infrastructure.
Your SUTA position is good. State unemployment treatment is not portable everywhere, and a favorable position can reset when you move.
The service problem is fixable. If the issue is hand-offs rather than capability, an escalation and a named-contact conversation sometimes resolves it. Ask for current references in your industry before assuming a different vendor solves it.
Alternatives to G&A Partners without co-employment
A meaningful share of people searching for G&A Partners alternatives do not want another PEO. They want out of co-employment itself: the PEO as employer of record on the W-2, the pooled health plan, the shared workers comp policy. There are three options, and they trade money for control in different places.
ASO, or administrative services only. The same payroll, HR and compliance administration, but you stay the employer of record and buy benefits and workers comp in your own name. You keep your plans and carriers, and give up the pooled medical and comp pricing that is usually the largest line in a PEO's favor. For groups under 50 employees in expensive small-group states, ASO often costs more in total even though the admin fee is lower.
Payroll software plus a benefits broker. Gusto or a comparable platform for payroll and HR, with a broker placing medical, dental and workers comp. Cheapest in software cost, most work for you, and benefits get priced on your own group: fine for a healthy census, painful for a small or older one.
Employer of record for the out-of-state minority. If co-employment exists only because of a handful of employees in states where you have no entity, an EOR for those people plus normal payroll for everyone else can replace the PEO. It gets expensive per head, so it works only when that group is small.
How to decide: put the G&A renewal, an ASO quote and a payroll-plus-broker quote on one page at total annual cost including benefits and workers comp, not admin fees alone. If the non-PEO total is within a few percent, the control is usually worth it. If the gap is 10% or more, the pooled pricing is doing real work and the better move is a different PEO. We run that comparison as part of the free side-by-side, and we tell you when leaving co-employment is the wrong call.
What to compare before you leave G&A Partners
Put every quote on the same census and compare six things: the admin fee structure (per employee per month or a percentage of payroll), master health plan versus carve-out, workers comp master policy versus your own, CPEO status, coverage in every state you employ in, and exit terms. The full checklist is in our ranking of the best PEOs and our switching guide covers the process step by step. If you would rather not run it yourself, the free side-by-side puts G&A Partners and the providers above on one page on identical assumptions.
What switching actually takes: the implementation timeline
The disruption is easy to underestimate, so plan for it. For most small and mid-sized businesses, implementation runs about four to eight weeks from a signed agreement to the first PEO-processed paycheck; employers with more locations and carriers take longer. The sequence is predictable: a signed Client Services Agreement opens a benefits enrollment window of roughly two to four weeks, then payroll cutover, then the first paycheck.
The work divides cleanly, and it is worth confirming that division in writing. The incoming PEO handles state registrations, tax setup and enrollment communications; you provide the employee data, the carrier elections and the cutover decisions. The biggest predictor of a smooth implementation is whether your data was clean on day one.
Timing decides how it feels. A switch aligned to the plan year is the clean case. A mid-year switch adds complexity mainly because of W-2 reporting: every employee gets one W-2 from the outgoing PEO through the switch date and a second from the incoming PEO. Doable, sometimes necessary, but a reason to plan the date rather than rush it. Our switching guide covers the sequence; the provider directory covers the wider panel.
FAQ
Is G&A Partners a CPEO?
Yes, and it is ESAC-accredited as well. That combination covers two things: federal employment tax certainty when you join mid-year, and independent assurance that payroll taxes and benefit premiums are being remitted. Not every alternative carries both, so verify it provider by provider.
Is Questco cheaper than G&A Partners?
Questco quotes rather than publishing price points, so the only honest answer comes from a quote on your census. The two usually land in similar territory for Texas mid-market companies, and service fit decides it more often than PEPM does. The credential gap runs the other way: Questco is CPEO-certified but not ESAC-accredited.
Why do companies leave G&A Partners?
Four reasons come up repeatedly: hand-offs between departments that feel slower than the dedicated-team promise, renewal pricing that moved faster than headcount, a footprint change that took the company outside G&A's strongest regions, and technology the platform does not deliver. The first is worth diagnosing before you shop; it is sometimes fixable with an escalation.
Will my benefits get worse if I leave G&A Partners?
Not automatically, but you have to design for it. G&A's plan stack is solid rather than top-of-market, so several alternatives can match it and a few beat it on carrier choice. The risk is a quiet step-down nobody notices until the first big claim. Compare plan by plan at the same tier and employer contribution.
Can I switch PEOs mid-year?
Yes, but it is expensive in disruption even when the dollar costs are reasonable. A mid-year switch means a W-2 split for every employee, two sets of tax filings, a 401(k) blackout during plan transfer, benefits re-enrollment and a COBRA handoff. If you can wait for your renewal date, wait.
How long does it take to switch to a new PEO?
For most small and mid-sized businesses, implementation runs about four to eight weeks from a signed agreement to the first PEO-processed paycheck; employers with more locations and carriers take longer. The path is a signed Client Services Agreement, a benefits enrollment window of two to four weeks, payroll cutover, then the first paycheck. Time it to the plan year where you can.
What hidden costs should I watch for in a PEO agreement?
The ones most often missed are implementation fees, payroll charges such as off-cycle runs and amended filings, minimum monthly fees, termination penalties, year-end processing, HR project fees and benefits administration charges. Renewal increases are the biggest one. Request a full fee schedule and a sample invoice before signing.
The practical takeaway
G&A Partners is a credible mid-market PEO with real service depth, both major credentials, mid-tier PEPM pricing and annual contracts with reasonable exit terms, which is a better starting position than most buyers realize. The reasons to look elsewhere are specific: hand-offs that made HR slow, a renewal that outran headcount, a footprint that moved, a risk profile that needs a vertical specialist, or a finance team that wants payroll infrastructure over consulting. Name the one actually driving the conversation, get apples-to-apples quotes from the whole market rather than the two names you know, read your own exit terms, and time the move to your plan year. Do that and you will either get a better deal or a good reason to stay.
If you would rather have the comparison done for you: tell us about your company and an advisor comes back with the two or three PEOs worth quoting, at no cost to you.
