What should a busy buyer read first?
Choose the website that answers your next hiring question. If you need reviewers, start with the work they will do. If you already have a team, focus on the tools and management support it needs.
For an RLHF services shortlist, write down a sample task and the rule for accepting a completed answer. A reviewer ranking code responses needs a different assessment from someone checking tone in customer support replies.
Use the resources below to prepare that scope before requesting proposals.
What do public hiring and pay benchmarks tell you?
These websites answer different questions:
| Website | What to read | How to use it |
|---|---|---|
| SHRM | Recruiting timelines | Plan internal approvals and interviews. |
| BLS | US software developer pay | Frame the engineering portion of a hiring budget. |
SHRM reports a 2025 median time to fill of roughly a month and a half for executive and nonexecutive roles. Its measure runs from job requisition to offer acceptance. Ask a provider to define the start and end of its hiring estimate before comparing it with that benchmark.
BLS reports a median annual wage of $135,980 for US software developers in May 2025. That figure describes software developers; it does not establish a rate for human feedback work. Get a separate quote for the role you intend to hire.
How should you compare nearshore and Latin American hiring models?
Compare who owns the work, then compare fees.
| Model you are considering | Question to settle in writing |
|---|---|
| Recruiting agency | Does the fee end at placement, and who handles employment afterward? |
| Staff augmentation | Who assigns daily tasks and checks each reviewer's output? |
| Managed service | What completed work must the provider deliver, and who approves it? |
| Employer of record service | Who employs the person, and what employment duties does the agreement cover? |
| RLHF platform | Does the price include people, software access or both? |
When reviewing business process outsourcing services, ask whether the proposed scope includes feedback review and quality checks. For software development services, specify whether you need engineering work, code evaluation or both.
What should you ask a provider before requesting a quote?
Send the same sample task to each provider. Ask:
- How will you test the subject knowledge this task needs?
- Who resolves disagreements between reviewers?
- What data can reviewers access, and how is access removed?
- What counts as accepted work, and who pays for corrections?
- Who manages absences and changes in workload?
- Does the price cover the person, employment costs and management time?
If you are considering outsourcing payroll services separately, ask who handles benefits and employment contracts. List those responsibilities alongside the payroll fee.
Opus is one option to discuss against that scope. This site is an Opus-owned reference; recommendations are editorial.
Where does Opus fit?
Opus states that the client chooses the finalist and manages day-to-day work. Its hiring process makes that management responsibility relevant when planning who will supervise feedback tasks.
According to its pricing page, 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.
Bring your sample task and expected hours to the conversation. Ask for a written quote and confirm how candidates will be assessed against your review rubric.

Questions & answers
Which rlhf services related websites should I read before hiring?
Start with SHRM for hiring timelines and BLS for US software developer pay. Use those benchmarks as context, then request a quote for your actual feedback tasks.
Can software developer salaries set my RLHF budget?
Use them only for context when the role includes software engineering. Ask for a quote based on the reviewer's subject knowledge, language skills and workload.
What should I check on an RLHF platform website?
Ask whether the contract includes reviewers, who checks their work, and how you can export completed labels and review history.
How should I compare managed services vs staff augmentation?
Ask who assigns tasks and owns quality checks. Put those duties in the contract before comparing prices.
What does a staffing service need to know about my feedback work?
Share sample tasks, the scoring rubric, required subject knowledge, expected hours and the name of the person who will manage reviewers.
What should I ask about nearshore or Latin American coverage?
Ask for each reviewer's working hours in your team's time zone, plus holiday cover and any schedule changes during US daylight saving time.
Should I include an employer of record service in my search?
Consider that model when you have selected a person and need employment support. Confirm who handles contracts, payroll and benefits.
What should I request before choosing among RLHF companies?
Request a written scope, a role-specific quote and a sample-task assessment. Agree on acceptance criteria and who pays for rework.
