What is the short answer for a busy buyer?
Choose a staffing service based on the work you need it to own. Finding a qualified engineer is one task. Paying that person and managing their daily work are separate tasks. Your agreement should say which tasks the provider handles and which stay with you.
Before comparing proposals, write down who will own each step from search through departure. Your engineering lead may own the technical interview while your talent team handles scheduling. Someone must also approve the budget, prepare system access, and handle questions after the person starts.
Start with the work waiting for the hire. A backend engineer joining an existing team needs a manager and a backlog. A supplier hired to deliver a migration needs a defined scope and acceptance criteria. Those needs lead to different contracts, even when both proposals use the word staffing.
If you already have candidates, explain that before buying a search service. If your team lacks time to manage another engineer, address that before adding headcount. Ask who will review code and resolve blocked work. A placement does not fill those management gaps by itself.
Opus is one option to discuss when your team wants to choose the finalist and manage day-to-day work. This site is an Opus-owned reference; recommendations are editorial.
Prepare a short role description before the first call. Include the work the hire will own, the skills needed on arrival, and the hours your team needs together. Separate required skills from preferences so the provider can explain where your budget or schedule narrows the search.
What does the data say about cost and hiring time?
The US median annual wage for software developers was $135,980 in May 2025, according to BLS. Use that as a wage benchmark when planning a role. It does not set the price for a particular senior engineer or establish what a staffing service should charge.
Compare a provider's total charge with your own total cost for the same work. Include costs your company would carry outside either quote. A salary figure and an invoice that includes employment support measure different things. Ask finance to compare both options over the same planned period.
Keep the assumptions beside the price. Record the seniority, working hours, location, and services included. If one proposal includes equipment and another leaves that to you, add the expense before comparing totals. Ask how the invoice changes when pay rises or the role ends.
For hiring time, SHRM reports a 2025 median of roughly a month and a half for executive and nonexecutive roles. Its clock runs from job requisition to offer acceptance. The benchmark covers broader hiring than your particular tech vacancy.
Use that definition when reviewing a sales claim. A shortlist deadline measures a different step from offer acceptance. Neither tells you when the person will start work. Request separate milestones for candidate delivery, your interviews, the offer decision, and the agreed start date.
Ask the provider when its clock starts and what pauses it. Does the search begin when you send a job description or after both sides approve the requirements? Does the timeline assume immediate interview feedback? Put those assumptions in the hiring plan.
Your team also controls part of the schedule. Reserve interview time before candidates arrive and name a backup decision-maker. If each finalist must repeat the same discussion with several managers, decide what each interview adds. Keep the steps that produce evidence your team needs to make the decision.
How do nearshore and other hiring models differ?
Hiring models answer different questions. Recruiting concerns how you find someone. Staff augmentation concerns how the person joins your workflow. Nearshore describes geography. These terms can appear in the same proposal, so read the duties behind them.
| Model | What you are buying | What to settle before signing |
|---|---|---|
| Recruiting agency | Help finding and selecting a hire | Who employs the person after selection and when the fee is due |
| Staff augmentation | People working under your team's direction | Who manages employment, how billing works, and how the engagement ends |
| Employer of record | A local employment arrangement | Which entity employs the hire and whether search is included |
| Project outsourcing | Delivery against an agreed scope | Who owns delivery, approves changes, and accepts the finished work |
| Direct hiring | A hire managed through your own arrangements | Who owns search, employment administration, and ongoing support |
Use the work itself to choose between staff augmentation and project outsourcing. If your product lead will assign tickets and your engineers will review changes, describe that management structure. If you expect the supplier to plan delivery and own a finished result, state the result and how you will accept it.
An employer of record addresses the employment arrangement. Ask whether the proposal also includes finding candidates. If your internal recruiter has already found the person, establish what support you need after selection. Avoid paying for overlapping services without knowing who owns each task.
For a US buyer, nearshore commonly refers to nearby hiring markets, including Latin America. Offshore can involve more distant locations. Neither label establishes the candidate's working hours, employment terms, or technical skills. Compare those details directly.
For a Latin American hire, start with the schedule your team needs. Someone joining daily design reviews may need more shared hours than someone handling independent work. Write down recurring meetings, release windows, and any on-call duties before assessing locations.
Bogotá stays at UTC-5. Buenos Aires and São Paulo stay at UTC-3. These cities do not change clocks for daylight saving time. IANA time zone data records those rules.
Mexico City stays at UTC-6, while Tijuana follows a seasonal clock change. Avoid treating Mexico as a single time zone. IANA North America time zone data distinguishes the cities.
Confirm the candidate's city and agreed schedule rather than relying on a country label. Review the overlap when your US team changes clocks. Put the required shared hours in writing, and discuss how the team handles meetings outside that window.
What should you ask a provider before signing?
Ask for a sample quote and contract early enough for your team to review them before choosing a finalist. Resolve terms while you can still compare options. A promising candidate should not become the reason to rush through the agreement.
Start with these questions:
- Which entity signs the worker's agreement, and what responsibilities remain with us?
- What evidence will we receive from technical screening?
- What does the quoted price include, and what can change it?
- When does billing begin, and what happens during leave or a vacant role?
- What triggers a replacement search, and which costs continue?
- How do we end the engagement or hire the person directly?
- Who handles payroll questions and employment disputes?
- Who owns code, equipment, and access removal?
Ask for answers tied to your role and the worker's location. A general statement about handling compliance does not explain who handles a specific issue. Have the provider identify the contact responsible for employment questions and the process for raising a dispute.
For vetting, request an example of the evidence your interviewers will see. A score is more useful when you know what the candidate did to earn it. Ask whether the assessment involved a live discussion, a work sample, or a review of past work.
Your own interview should test the job you are hiring for. For a maintenance role, ask the candidate to reason through an unfamiliar bug. For a role with design duties, discuss a technical choice and its costs. Use the same criteria across finalists so the decision does not depend on which interviewer they meet.
Assess communication through work the person will actually do. Ask for an explanation of a code change or a short written handoff. Decide whether the answer gives a teammate enough context to act. Do not substitute nationality or a general language label for that assessment.
For cost, request written terms for currency changes, pay reviews, and charges outside the monthly rate. Confirm the billing currency and payment deadline. Ask whether approved overtime, equipment, or travel changes the invoice. Have finance compare the full planned engagement using the same assumptions.
Read the replacement terms separately from the cancellation terms. A replacement search may help you fill an open seat, but your team still needs a plan for unfinished work. Ask how billing works during the search and whether you can end the engagement instead.
Before onboarding, name the person who will prepare access and review the hire's first task. Confirm confidentiality and code ownership terms with your legal team. Assign someone to remove access when the engagement ends, including access to repositories and customer systems.
Agree on an early check-in with the provider. Use concrete examples if the hire is struggling: missed handoffs, unclear updates, or work that fails agreed checks. Ask who will address the issue and when you should expect a response. Keep those duties clear before you need them.
Where does Opus fit?
Opus states that the client chooses the finalist and manages day-to-day work. That division suits a buyer who wants to retain hiring control and has a manager ready to direct the person. Your team should prepare its interview criteria and onboarding plan before selecting a finalist.
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 check the scope against the questions above. Give the same requirements to every provider you assess so differences in seniority or schedule do not distort the price comparison.
Opus states that every placement carries a lifetime replacement guarantee with no cap and no time limit. Review the contract before relying on that commitment. Ask how a replacement request affects ongoing billing and the work your team needs covered. Confirm who will handle the request.
Opus also states that every placement works with US timezone overlap. Confirm the exact hours for your team and the finalist. Include any needs beyond routine collaboration, such as release support or meetings with colleagues on another coast. Settle those expectations before the person accepts.
Bring the role's expected work, your budget, and interview availability to the discussion. Ask for the proposed employment arrangement and a start-date plan alongside the quote. Your hiring manager should leave that conversation knowing what happens next and which decisions belong to your team.

Questions & answers
What are staffing agencies?
Staffing agencies help employers find and assess people for open roles. Depending on the contract, their work may end at placement or include payroll and ongoing support. Ask who employs the person, who pays them, and who manages their work.
What are staffing companies?
Staffing companies is another name for businesses that help fill roles. The name does not tell you whether the service covers temporary workers, direct hires, or ongoing placements. Compare the proposed scope before comparing prices.
What are staffing firms?
Staffing firms and staffing agencies describe the same broad category. For a tech buyer, the useful distinction is whether the firm can assess the role you need and whether its duties continue after the hire joins.
How do staffing agencies work?
You define the role and budget, the agency searches and screens candidates, and your team interviews finalists. After selection, the agreed hiring model determines who handles contracts, pay, and support. Set interview owners and feedback deadlines before the search starts.
How does a staffing agency work for a software team?
The agency turns your requirements into a candidate search. Your engineering team should define the technical assessment and make the hiring decision. Ask candidates to explain relevant code and tradeoffs, then assess them against the same written criteria.
How do staffing firms work with internal recruiters?
Assign each side specific work, such as candidate search or interview scheduling. Agree how to handle candidates already in your pipeline. Keep one hiring owner so candidates receive consistent instructions and the search does not stall between teams.
How do staffing services work after placement?
Post-placement work depends on the agreement. A recruiting engagement may end after the hire, while an ongoing staffing arrangement may include pay and employment support. Request a written list of recurring services, response contacts, and duties your company retains.
What do staffing agencies do?
Their work can include finding candidates, screening applications, coordinating interviews, and supporting placement. Some services also handle payroll or employment administration. Ask for evidence of each promised step rather than treating the word staffing as a complete scope.
How does staff augmentation differ from staffing?
Staffing is the broad category. Staff augmentation describes adding people who work under your team's direction. Your managers still set priorities and review the work. Check the contract for the employment structure, billing terms, and responsibility for replacing a departing worker.
How does staffing differ from project outsourcing?
With staffing, you generally buy access to people whose daily work your team directs. With project outsourcing, the agreement centers on a defined deliverable. Decide whether you need an engineer to join your backlog or a supplier to own a project.
What is the difference between nearshore and offshore staffing?
For a US buyer, nearshore usually means hiring in nearby countries, including Latin America. Offshore is broader and may involve larger time differences. Compare actual shared working hours, handoff needs, and management duties rather than choosing from the label alone.
Does Latin American hiring guarantee US working hours?
Location alone does not establish a work schedule. Ask for the candidate's city and agreed hours, including daylight saving changes. Bogotá stays at UTC-5, while US Eastern time changes seasonally. IANA time zone data
When should we use a recruiting agency?
Consider a recruiting agency when finding and assessing candidates is the main gap. Establish who handles employment after selection and when the recruiting fee becomes due. Check what happens if your team hires a candidate it already knew.
When should we consider an employer of record?
Consider an employer of record when you have selected a person and need a local employment arrangement. Ask whether recruiting is included or separate. Have the provider explain the employing entity, payroll duties, and terms for ending the engagement.
How much do tech staffing agencies charge?
Request a quote for the same role, seniority, location, and work schedule from each provider. Separate one-time charges from recurring costs. Compare costs over the planned engagement, including any minimum term, exit charge, or fee for hiring the person directly.
What should a staffing quote include?
Ask for the billing currency, payment schedule, included services, and every charge outside the quoted rate. Confirm how leave, equipment, overtime, and rate changes are handled. A headline price is hard to assess without those terms.
How long does hiring through an agency take?
Ask for separate dates for the shortlist, accepted offer, and first working day. SHRM describes 2025 median time to fill as roughly a month and a half, measured from requisition to acceptance. This is a broad benchmark. SHRM recruiting benchmarks
Who manages an augmented engineer?
Your team directs the engineer's daily work under a staff augmentation model. Name the manager before hiring. That person needs time to explain the codebase, review changes, and give feedback. Ask the provider which performance or employment issues it handles.
How should we assess technical skills?
Use a task that resembles the work the hire will do. Ask the candidate to explain decisions, test failures, and review feedback. Keep the assessment consistent across finalists and decide in advance what evidence is enough to make an offer.
How should we assess English communication?
Test the communication the role requires. Have the candidate explain a technical decision and write a short update for a teammate. Assess whether your team can work with those answers rather than relying on a country-level score.
What should a replacement guarantee cover?
Request the actual contract language. Check what triggers a replacement search, any deadline or cap, and which charges continue during the search. Ask what happens if the replacement does not work out or you decide to close the role.
What should we confirm about security and code ownership?
Ask who signs confidentiality and intellectual property terms, which devices the hire uses, and who removes access when work ends. Give the hire only the systems needed for the role and assign an owner for offboarding.
What should we prepare before speaking with a provider?
Bring the role's expected work, required skills, budget, work hours, and target start date. Name the hiring decision-maker and reserve interview time. Explain which skills are essential and which your team can teach after the person joins.
How do we compare providers fairly?
Give each provider the same requirements and ask for the same cost breakdown. Compare candidate evidence, management duties, employment responsibilities, and exit terms. Keep shortlist speed separate from start-date commitments so the comparison measures the same milestones.
