7 Questions to Ask a ReactJS Agency Before Hiring

Use the Same Questions with Every Shortlisted Agency

Bring a short project brief and use these questions in the first serious conversation with a ReactJS agency. Record the answer, evidence promised, unresolved assumption and person responsible for following up. That makes proposals easier to compare afterwards.

This is an interview worksheet. For the full evaluation process and weighted scorecard, use our ReactJS agency selection guide .

1. Who Will Actually Work on Our Product?

Ask for the proposed engineers, their responsibilities, expected allocation and availability. Find out whether the people in the interview are the people who will join the project.

Request a follow-up introduction to the delivery team. Clarify how specialists are involved, who reviews technical decisions and what happens if someone leaves or becomes unavailable. Record replacement and handover arrangements before kickoff.

2. What Would You Deliver First, and What Would You Leave Out?

Ask the agency to describe a first milestone that users or stakeholders can evaluate. The answer should include a usable outcome, assumptions and explicit exclusions.

Follow up with: what do you need from us before starting, and which unknown could change the plan? A useful response exposes dependencies rather than treating every feature as equally ready to build. For an MVP, compare the answer with our timeline and scope guide .

3. Can You Show How You Solved a Comparable React Problem?

Ask for a permitted code walkthrough, architecture discussion or reference from work with similar constraints. Have the engineers explain the problem, their responsibility, the tradeoff they made and what they would change now.

If the discussion stays at the level of library names, arrange a focused React technical assessment . Respect client confidentiality: a supplier should not need to expose private code to demonstrate judgment.

4. How Will We Know the Work Is Ready to Release?

Ask for acceptance criteria and examples of how the team checks important user journeys, permissions, failure handling, accessibility and supported devices. Clarify what your own team is expected to review.

Follow one change through code review, testing and deployment. Then ask who monitors the release and how they recover from a problem. Record who owns those responsibilities after the project ends.

5. What Is Included in the Estimate, and What Changes It?

Request the work breakdown, team allocation, rates or price, assumptions and exclusions. Establish how discovery, design, testing, coordination, release and support are accounted for.

Ask when you will receive an updated forecast and what approval is required before spending beyond an agreed limit. A fixed price still needs an agreed scope and change process. Our software estimation guide provides a structure for comparing the numbers.

6. How Will Our Team Get Access and Take Over the Work?

Discuss access to repositories, environments, designs, documentation and the accounts used to operate the product. Ask what knowledge transfer is included and what an internal engineer will need to deploy and maintain it.

Clarify ownership and third-party dependencies in the agreement, along with handover and exit arrangements. Record the practical tasks and deliverables rather than relying on a general assurance that everything will be handed over.

7. Can We Speak to a Client with Similar Delivery Conditions?

Ask for a reference relevant to your situation: a legacy codebase, a small internal team, a complex integration or a fixed business deadline. A matching delivery challenge may be more useful than a matching industry label.

With the reference, discuss whether the promised team did the work, how unexpected problems were handled and whether the result was maintainable. Ask what the client would organize differently in another engagement.

Turn the Answers into a Decision

Keep a short record for each question: the supplier's answer, supporting example or reference, open question, follow-up owner and decision date. Mark missing evidence clearly so it does not turn into an assumed capability.

Use the agency selection scorecard to combine those findings with your priorities. If a substantial uncertainty remains, define a small paid first step with a concrete output before agreeing the wider engagement.
