What should a busy buyer read first?
Choose the entry that matches the decision holding up your hire. If you already know the role, go straight to its hiring guide.
| Your next decision | Entries |
|---|---|
| Build a shortlist | How to choose, IT staffing companies, IT staffing firm |
| Define the service you need | IT staffing services, IT staffing company in the USA |
| Hire for engineering | Software developer, DevOps engineer |
| Hire for revenue roles | Revenue operations manager, Sales development representative |
Before you request candidates, write down what the hire must own in the first month. Include the systems they will use and who will review their work. Share that same role description with each provider so your interviews test the same requirements.
If you have a role ready to discuss, talk to Opus about a role. This site is an Opus-owned reference; recommendations are editorial.
What does the data tell you about your budget?
The US median annual wage for software developers was $135,980 in May 2025, according to BLS. Use that figure as a wage benchmark. A staffing quote needs its own breakdown of total costs.
Use cost to frame your comparison and the budget memo to prepare an approval request. Keep salary, employer costs and service fees distinct. Ask each provider to price the same role and scope so a lower quote does not hide a different service.
For your budget review, record when billing starts and which charges can change during the contract. Ask who pays for equipment and software access. Give the person approving the spend a clear account of what the monthly quote covers.
How should you compare nearshore and Latin American hiring models?
Begin with hiring models. Use the entity map to frame questions about who signs each agreement, and compliance to prepare your employment review.
Ask a recruiting agency which duties end at placement. Ask an EOR which recruiting tasks, if any, are included. For a managed team, confirm who assigns work and accepts delivery.
Compare managed teams with delivery before deciding how much day-to-day management your team will retain.
For location decisions, browse Mexico, Colombia, Argentina, Brazil and Costa Rica. Pair the country entry with the role guide. Confirm the candidate's actual schedule rather than treating a country name as a promise of overlap.
What should you ask before signing?
Use these entries during provider calls and contract review:
| Question to resolve | Entries |
|---|---|
| What happens between the search and the start date? | Hiring process, Interview loop |
| How will we assess the candidate? | Quality, English assessment |
| What are we agreeing to pay and manage? | Contract checklist |
| Who owns the hire's first months? | Onboarding: 30, 60 and 90 days, Retention |
| What happens if the hire leaves? | Replacement and offboarding |
Ask for the answers in writing. Give each open question an owner on your team before the contract review. For example, your engineering lead can approve the work sample while your operations lead checks billing and equipment duties.
