What is a staffing service

# What is a staffing service

What is the short answer for a busy buyer?

A staffing service helps you fill a role. Its scope can end when you hire a candidate or continue through payroll and employment support. The contract should tell you where that responsibility starts and stops.

For a hiring manager, the first decision is whether you need a person to join your team or a provider to run work. Those needs lead to different agreements.

Suppose your engineering lead has a backlog and can review another developer's code. Staffing may fit that need. If nobody on your team can define the work or review it, adding a developer leaves that management gap open.

The same choice applies to reinforcement learning from human feedback, or RLHF. You might need evaluators who follow your team's instructions. Or you might need a provider to manage a batch of evaluations against agreed acceptance criteria. Write down which result you expect before requesting proposals.

How do staffing services work?

Start with a role description that names the work. Include the skills someone must demonstrate, the hours they must share with your team, and the manager they will report to.

A typical buying process then follows these steps:

1. Agree on the service scope, budget, and contract terms.
2. Give the provider clear screening criteria and examples of acceptable experience.
3. Review candidates and assess their work against the same criteria.
4. Choose a finalist and confirm the employment arrangement.
5. Agree on a start date and prepare access, equipment, and onboarding.
6. Review performance and resolve any problems through the agreed process.

Ask who owns each step. A provider may screen candidates while your team runs technical interviews. Someone still needs to schedule those interviews, collect feedback, and make the offer decision.

Keep the hiring decision separate from the start date. An accepted offer does not mean the person has finished notice, received equipment, or gained access to your systems.

For ongoing staffing, name an internal manager before the search begins. That manager should have time to explain tasks and review work. Include those hours in your staffing plan.

What does the data say about hiring time and cost?

Hiring benchmarks can help you plan a search. They cannot tell you what a specific provider will charge or when your chosen candidate will start.

Use hiring benchmarks with matching definitions

SHRM describes median time to fill in 2025 as roughly a month and a half for executive and nonexecutive roles. Its measure runs from job requisition to offer acceptance. SHRM recruiting benchmarks

Use that definition when you compare a provider's timeline. A promise to send candidates measures a different stage from an accepted offer. Neither measures the time until a new hire can complete useful work.

Ask for separate dates for the shortlist, interviews, offer decision, and first working day. Then add your own onboarding steps. If security review must happen before access is granted, put it on the schedule.

For reported hiring averages, ask which roles and locations were included. Ask whether the clock pauses while clients review candidates. A timeline is easier to assess when its start and end points are clear.

Compare wages with wages and service quotes with service quotes

BLS reports a median annual wage of $135,980 for US software developers in May 2025. That is a wage benchmark, not an all-in staffing price. BLS software developer pay

Do not use that figure as the assumed cost of every engineering role. It also does not establish the cost of a researcher, evaluator, or annotation lead.

For your own comparison, list the costs included in each option. Ask about recruiting fees, employer costs, benefits, equipment, and ongoing support. Include your managers' interview and onboarding time in the internal plan.

A monthly service quote and a candidate's salary can look far apart because they cover different expenses. Request a written explanation of what the service price includes before calculating savings.

Avoid a savings percentage built from a broad US wage benchmark and a quote for a different level of experience. Compare the same job scope and the same period of work.

Check the schedule behind nearshore claims

Mexico City is UTC-6 and does not observe daylight saving time. Bogotá is UTC-5 year-round. Their relationship to US offices changes when those offices move between standard and daylight time. IANA North America, IANA South America

The practical question is when the candidate will work. Ask for a schedule in both the candidate's city and your team's time zone.

Include recurring meetings, review sessions, and any on-call duty. A shared afternoon may suit code reviews but fail a role that needs early customer calls. Confirm the schedule again for the other US daylight saving season.

How do the hiring models differ for nearshore and Latin American teams?

Nearshore describes location relative to the buyer. It does not define who employs the worker or who owns delivery. Latin American hiring can use several models, so compare the responsibilities in the agreement.

Treat these as buying categories. A proposal may combine recruiting and employment support. Require a written scope rather than relying on the category name.

When does recruiting fit?

Use recruiting when you need help finding and assessing candidates and have a way to employ the person.

Confirm what happens after the placement. Ask whether the fee includes follow-up support and what triggers a replacement search. If you need payroll or benefits support, name that requirement before accepting a recruiting-only proposal.

Direct placement also needs a clear handoff. Your team should know when it takes over offer paperwork, onboarding, and employee support.

What is an employer of record service?

An employer of record, or EOR, is the legal employer for a worker while the client directs daily work. This model can fit when you have found a candidate and need an employment arrangement in that country.

Ask whether the proposal includes recruiting. Do not assume a monthly employment fee includes finding or assessing candidates.

Get the employing entity's name and a written division of duties. Your HR team should know who answers questions about pay, leave, and employment changes. Your hiring manager should know where performance feedback goes.

What does staff augmentation mean?

Staff augmentation adds people to a team you manage. You assign tasks, set priorities, and review their output.

For example, an added developer may work from your backlog and submit changes through your review process. An added evaluator may use your rubric and escalate unclear cases to your research lead.

This model fits when the team has work ready and someone who can supervise it. If the rubric is still changing, budget time for that supervisor to explain revisions and check how people apply them.

What is the difference between staff augmentation and managed services?

The main distinction is who manages the agreed work.

With staff augmentation, you buy capacity and direct its use. With managed services, the provider manages a defined scope under agreed terms. Your team still needs to set requirements and decide whether the output meets them.

For RLHF services, write down who trains evaluators, resolves disputed ratings, and approves completed batches. Specify how revised instructions affect price and deadlines.

IT outsourcing services is a broader label. It may describe managed support, a development project, or another external service. Ask whether the proposal sells staff time, defined outputs, or an ongoing service level.

A provider handling employment paperwork does not automatically own your product deadline. Put delivery duties in the contract if you expect the provider to carry them.

What should you ask a provider before signing?

Send the same role description and questions to each provider. That gives you a basis for comparing proposals without guessing what each price includes.

What work will the person own?

Describe the expected output in terms a manager can review. For a developer, that might be a working integration with tests. For an evaluator, it might be completed ratings with clear reasons and an escalation path for uncertain cases.

Ask candidates to explain a relevant work sample. Use a paid assessment when you need to see them perform a task. Decide how you will score it before reviewing submissions.

For specialized AI work, distinguish subject knowledge from skill with the evaluation process. Ask how the candidate handles ambiguous instructions and disagreement with another reviewer.

What exactly does the price cover?

Request a quote for the role and location you intend to hire. Ask the provider to identify:

• The recurring service charge and billing currency.
• Any setup, search, or placement fee.
• Payroll, benefits, and employment support included in the charge.
• Equipment and software costs.
• Treatment of leave, holidays, and overtime.
• Rate changes, minimum terms, and termination charges.
• Any fee or restriction for hiring the person directly.

Ask what can change the quote after signing. A flat monthly charge still needs a clear scope and change process.

Compare the full expected contract period. A low initial charge is hard to assess without renewal and exit terms.

Who handles employment and access?

Ask for the legal employer's name, the governing agreements, and a contact for employment questions. Have your legal team review the arrangement for the worker's location.

Confirm how work product reaches your company and how confidentiality duties apply. Ask whether the provider uses subcontractors and who can access your data.

For AI work, define which datasets and tools the worker may use. Set rules for copying data, using personal devices, and submitting material to external AI tools. Agree on access removal when the assignment ends.

How will you judge success after the start date?

Choose review points tied to the work. A new hire should know what the manager expects and how feedback will arrive.

For an engineering role, review actual changes and the support the person needs to complete them. For evaluator work, review ratings against your rubric and examine disputed cases.

Separate a skills problem from an onboarding problem. If access is delayed or instructions conflict, fix that before deciding the hire cannot do the job.

Ask the provider how concerns are raised and who responds. Your manager should not have to discover the escalation process after a missed deadline.

What happens if the hire leaves or does not work out?

Read replacement terms alongside the termination clause. Ask what starts a replacement search, whether billing continues, and what support applies during the gap.

Clarify whether the remedy is another search or something else. A replacement promise does not by itself establish a refund, temporary cover, or a deadline for the next hire.

Before signing, agree on the handover process. Name who collects unfinished work, removes access, and returns equipment.

Where does Opus fit?

This site is an Opus-owned reference; recommendations are editorial.

Opus states: "The client chooses the finalist and manages day-to-day work." That division of responsibility suits a buyer who wants to select the hire and keep daily management inside the team.

If your engineering lead will assign tickets and review code, assess the candidate against that workflow. If your research lead will set evaluator instructions, confirm that the lead has time to review judgments and answer questions.

Talk to Opus about a role.

What does the monthly charge include?

Opus states: "Opus charges one flat monthly rate per hire. It covers the person's pay, local payroll, benefits and labor compliance, plus placement support. There is no separate recruiting fee. The rate depends on role, seniority and location."

Published dollar rates: Not published.

Ask for a written quote for your role and confirm its scope. Use the same cost checklist you would use for any staffing proposal. Record the duties your own team will retain, including supervision and work review.

What should you confirm about support and overlap?

Opus states: "Every placement carries a lifetime replacement guarantee with no cap and no time limit."

Review the agreement to understand how to request a replacement and what happens while a search is underway. Keep that process separate from any requirements you have for project delivery.

Opus also states: "Every Opus placement works with US timezone overlap."

Turn that into an agreed schedule for your hire. Name the meetings and review windows the person must attend. Confirm how you will handle holidays and changes to the US clock.

Bring a role description that names the work, the manager, the required hours, and the evidence you need from candidates. For AI evaluation work, include a sample task and the criteria your team will use to judge it.
