A German maker of automotive wiring harnesses is building a plant in Querétaro to supply US carmakers. By the end of next year it needs 220 line operators, fifteen maintenance technicians, a plant manager and a bilingual HR lead. Before 2021, its sister plant in Coahuila simply used an outsourcing company that kept operators on its own payroll.
Now the regional director has three proposals that sound alike. A staffing group offers “servicios especializados” to supply operators for the production line. A local agency offers recruitment and selection for a fee per hire, with operators on the company’s own payroll. A payroll firm offers to process that payroll. Two of the three are lawful. The third would cost the company its tax deductions on the operators’ pay, make it jointly liable for their rights and expose it to fines.
Mexico’s recruitment and HR-services market was rebuilt by the outsourcing reform of April 2021. Firms that once kept large workforces on their own payrolls for clients now sell recruitment, selection, payroll processing, consulting and genuinely specialised services, and the employer, not the agency, carries the consequences of getting the line wrong. This guide explains the rules in plain terms, how fees work, and profiles sixteen firms established in Mexico: recruitment and staffing groups, executive search firms and HR consultancies. It belongs to the Finding the Right Person hub and pairs with our playbook on recruiting in Mexico; for the global view, see HR consulting and recruitment firms worldwide.
In short
Subcontracting personnel has been banned since April 2021; only specialised services or works outside your corporate purpose and predominant activity, from a REPSE-registered provider, may be outsourced.
Recruitment and selection agencies (agencias de colocación) remain lawful and are not the employer: the hire goes on your payroll, with IMSS registration and profit sharing (PTU).
Fees are often quoted in months of salary, roughly equivalent to 15–25% of annual pay; retained search is standard for senior roles.
Check every provider on the STPS public REPSE register; an unregistered one can cost tax deductions, VAT credits and fines of 2,000 to 50,000 UMA.
How the recruitment and HR-services market works in Mexico
Mexico runs two hiring markets. The professional one, centred on Mexico City, Monterrey and Guadalajara, relies on LinkedIn, OCC Mundial and headhunters for bilingual engineers, finance staff and managers. The operative one, around the industrial parks of the north and the Bajío, needs volume: operators, warehouse staff and technicians, often hired in waves as nearshoring plants ramp up. International groups such as ManpowerGroup, Adecco, Randstad and PageGroup serve both, alongside Mexican firms that are often stronger in one region or sector.
Contingency fees are commonly quoted as months of salary, typically equivalent to about 15–25% of annual pay at the time of writing (November 2026), and retained search is the norm for directors. Align the agency’s guarantee with the statutory trial period: the Federal Labour Law allows up to 30 days, extendable to 180 days for management and specialised technical or professional roles, so a 90-day guarantee for a director should sit inside a longer trial. Private placement agencies need STPS authorisation, a procedure the ministry merged with the start-up notice and shortened in June 2026. Our agency fees guide compares norms internationally.
The 2021 outsourcing reform in plain terms
The decree published in the Diario Oficial de la Federación on 23 April 2021 prohibits subcontratación de personal: one company providing its own workers for another’s benefit. Two exceptions survive. Specialised services or works may be contracted if they are not part of the client’s corporate purpose or predominant economic activity and the provider is registered in the Registro de Prestadoras de Servicios Especializados u Obras Especializadas (REPSE) with the labour ministry, renewing every three years. Services between companies of the same group follow the same test. Contracts must be written and state the services and approximate headcount, and providers report their contracts to IMSS and INFONAVIT every four months.
The penalties are real. The client is jointly liable with a non-compliant provider for workers’ labour, social-security and housing-fund obligations; payments for prohibited subcontracting cannot be deducted for income tax or used for VAT credits; and the labour law sets fines of 2,000 to 50,000 UMA. The reform also capped profit sharing (PTU) at three months’ salary or the worker’s average PTU over the last three years, whichever is higher, which removed much of the old incentive to keep staff off the operating company’s books. In June 2026 an STPS simplification agreement merged REPSE registration, renewal and cancellation into a single procedure and cut processing times, and the REPSE portal lets anyone search the public register by name or RFC.
A simplified test for outsourcing proposals in Mexico. Specialised services still require a written contract and ongoing checks.
What staffing and HR firms can still do for you
Plenty. Agencies recruit, screen, test and train candidates whom you then employ; specialised providers run services such as security, cleaning, canteens or IT maintenance when these are genuinely outside your core activity; payroll firms process payroll for workers who remain your employees; and HR consultancies design pay structures, run salary surveys and implement compliance programmes such as NOM-035 on psychosocial risk. What they cannot do is put their employees on your production line or sales floor. If you need temporary capacity, hire directly on a fixed-term or seasonal contract where the law allows it. AMECH, the industry association, is lobbying to legalise temporary work agencies, but at the time of writing they remain outside the law. Plan also for the phased cut in the working week from 48 to 40 hours between 2027 and 2030, which will raise demand for recruitment and workforce-planning help.
Watch outWatch for “specialised” contracts that are not. A provider registered in REPSE for, say, logistics services cannot lawfully supply line operators for your core manufacturing, whatever the contract calls it. The REPSE number proves registration, not that your particular service qualifies.

Most global search firms work from Mexico City, and several also have Monterrey offices for the large family-controlled industrial groups of Nuevo León. For plant-manager and general-manager roles, ask for evidence of searches in your sector and region: a Monterrey candidate may not move to the Bajío without a convincing package for the family.

Mexican HR consulting centres on pay benchmarking, organisation design, payroll and compliance with the labour law and its standards (NOMs). Compensation surveys matter because Mexican offers are built from many components (aguinaldo, vacation premium, food vouchers, savings funds), as our guide to setting the pay band before you post explains.

Choosing and briefing a Mexican firm
Brief in writing with a scorecard, the gross monthly salary range and benefits package, the required English level and the plant or office location. Decide first whether an agency is the right channel at all: for operators, referrals, plant-gate recruiting and the public employment service often beat paid search, as the hiring-channel decision matrix shows.
● Before you engage a recruitment or HR firm in Mexico · 11 questions
1Is the firm providing recruitment only, or will its people work for us?Recruitment is lawful; supplying staff for your core activity is prohibited subcontracting.
2If it offers specialised services, is it on the REPSE register, and does our service genuinely fall outside our corporate purpose?Registration alone does not make a service specialised.
3Does the agency hold STPS authorisation as a placement agency?For-profit placement agencies need authorisation.
4Who will be the employer, and who registers the worker with IMSS from day one?With a recruitment agency, it must be you.
5How is the fee calculated: months of monthly salary, or a percentage of annual pay including aguinaldo?The base changes the cost materially.
6Does the guarantee fit the trial period we will use?Up to 30 days, or 180 for management and specialised roles.
7How will the firm handle candidates’ personal data and psychometric results?Mexico’s 2025 data-protection law applies to recruitment files.
8Will its ads avoid discriminatory filters such as age, sex or marital status?Mexican law prohibits discrimination in hiring, and ads placed for you are your exposure.
9Can it recruit in the region where the plant is, not just in Mexico City?Operative markets are local; ask for regional references.
10For payroll or HR BPO: will workers stay on our payroll, with filings in our name?Payroll processing is lawful only if you remain the employer.
11Which companies are off-limits to the search firm?Ask before an exclusive senior mandate.
Consultant’s notePut a REPSE check into your accounts-payable process, not just procurement. Ask finance to verify the provider’s registration and the contract’s service description before the first invoice is paid, and to keep the provider’s IMSS and INFONAVIT compliance evidence on file. That is where an auditor will look.
