The best questions to ask a software development company turn sales claims into evidence. A Product Manager needs to know who will actually deliver the product, how the team handles changing priorities, how progress and risks become visible, and what happens if the partnership ends. What matters most is not how convincing an answer sounds, but the people, processes, artifacts, references, and ownership arrangements behind it. No single answer predicts project success, but the right questions make vendor comparison far more concrete.
-
Evaluate the people assigned to the product, not the software company's total headcount.
-
Treat “Agile” as a label until the vendor can show how work, risks, feedback, and changes become visible.
-
Ask for evidence after important claims, such as named roles, demos, references, workflows, or documented practices.
-
Turn security promises into specific secure development practices and clear responsibilities.
-
Separate contractual ownership of code from practical control of repositories, infrastructure, documentation, and product knowledge.
-
Compare vendors by the evidence supplied and risks left unresolved rather than by an arbitrary numerical score.
Questions to Ask a Software Development Company About Your Product and Team
The first five questions test two things: whether the company understands the product and whether the proposed delivery team can execute the work. A broader custom software development company model can cover several delivery needs, but you still need to verify the actual team and its operating context before making a commitment. Company credentials are not a substitute for delivery-team capability. Relevant experience helps, but it does not guarantee a successful project.
1. What Should a Software Development Company Understand About Your Project's Requirements Before Estimating?
A credible estimate starts with the product goal, users, constraints, assumptions, risks, and definition of success. A precise estimate has little value when major uncertainties remain hidden.
The quality of the questions a vendor asks is useful evidence in itself. A structured product discovery services process can clarify those unknowns before they turn into delivery assumptions. The estimate can then distinguish what is known, what is assumed, and what still needs validation.
Selleo uses Product Discovery to clarify product goals, users, constraints, risks, and success criteria before those inputs drive delivery decisions.

2. Have You Delivered Projects Similar to Mine - and Can You Provide References?
“Similar” does not have to mean an identical application. Relevant similarity can come from the product problem, domain, technical constraints, scale, client market context, or delivery environment. Ask which previous project is comparable to yours and, more importantly, why.
References add another layer of evidence. They can show how the team communicated, reacted to changing priorities, and handled difficult delivery periods. Past experience demonstrates capability, but it does not guarantee future results.
Selleo's work with Humly provides a concrete example through its 7-year partnership on AI-driven recruitment software, rather than relying on a generic claim about years of experience. Selleo specializes in EdTech, HRTech, and FinTech, and has also delivered products used by over 2 million users. Its portfolio also includes Catalyst for 1100+ hospitals and Finpay, where the team completed over 1500 templates.
A named, relevant case is stronger evidence than an impressive client logo without context.
3. Who Will Actually Work on My Software Development Project?
Ask about the people expected to deliver the product: their roles, seniority, relevant skills, allocation, and availability. The goal is to evaluate the actual candidates assigned to your project, because total company headcount says little about the capability available to a specific engagement.
Request enough information to understand the proposed team before kickoff. Staffing can change for legitimate reasons, but a senior team presented during sales should not turn into a materially different delivery team. Ask about each person’s relevant job history, career path, and previous employer only when that context helps assess their fit for the position.
Selleo emphasizes experienced developers and direct communication with the people doing the work, keeping product and technical discussions close to delivery, with experience working on similar products or in comparable technical contexts.
You are not hiring a software company's headcount. You are hiring the specific people who will make product and technical decisions with your team.
After these three questions, the difference between a claim and useful evidence becomes easier to see:
The exact wording matters less than the pattern. A strong evaluation moves from a statement to something you can inspect or verify. The interview or vetting stage should help determine whether the proposed team’s skills and work ethic match the project, and whether each hire fits the role like the right person for the job.

4. How Will You Onboard Into Our Product, Users, and Existing Software Design?
Onboarding needs to cover more than repository access. The incoming team needs context about users, product goals, backlog, existing architecture, constraints, stakeholders, and decision rights. Without that context, developers have less information for making useful delivery decisions.
Ask how the team will acquire that knowledge and where it will live. This matters particularly when evaluating staff augmentation, because adding engineering capacity only helps when new people can work inside the existing product context. The objective is productive autonomy, not a second team that requires constant translation. Onboarding should also clarify how involved the client needs to be during requirements, context transfer, and early delivery decisions.
Weekly updates help keep onboarding progress and open questions visible.
A strong partner enters through structured product and technical context rather than immediately treating the backlog as an isolated queue of tickets.
A development team should understand the product before trying to accelerate delivery. That means learning the users, business goals, existing architecture, backlog, constraints, and decision-making context. Adding developers without that context can simply create more work for the Product Manager. At Selleo, discovery and onboarding are meant to give engineers enough context to contribute to product and technical decisions, not just execute tickets. Direct communication with developers keeps those decisions close to the people doing the work. The goal is a team that can become increasingly autonomous without disconnecting from product priorities.
5. Which Specific Technologies Do You Recommend - and Why?
Technology names matter less than the reasoning behind them. Recommendations need to reflect programming expertise the team can support long term. Ask how the proposed technologies fit the existing system, product constraints, maintainability needs, available expertise, and expected roadmap.
The same principle applies to adjacent capabilities. For example, UX design may matter when product risk includes usability, while DevOps and cloud services become relevant when deployment and infrastructure are part of the delivery problem, including AWS where cloud operations are in scope. The reasoning should also explain when React and GraphQL fit the frontend, when Ruby on Rails or Node.js fit the backend, and when React Native or PWA make sense for mobile delivery. Neither capability belongs in the proposal merely because the vendor offers it.
Strong technical advice connects implementation choices to product consequences instead of treating a familiar stack as the default answer.

Good Questions About the Development Process and Working With a Software Development Partner
A workable delivery model keeps decisions, progress, priorities, and risks visible without turning the Product Manager into a full-time vendor coordinator. A software outsourcing company can add engineering capacity, but the operating model determines how much coordination that capacity creates.
Five things need to remain observable during delivery:
- who owns backlog priorities and delivery decisions;
- what working product increment or other evidence of progress is visible;
- what the Product Manager and development team each own;
- how scope and priority changes affect delivery;
- how blockers, risks, and unresolved decisions are escalated.
The useful test is not how many ceremonies a vendor runs, but whether the Product Manager can understand what is happening and act on it.
6. How Will You Work With Our Backlog and Changing Priorities?
Clarify who prioritizes the backlog, how work enters development, and how new information changes planned work. The vendor also needs to explain where trade-offs are recorded and who has authority to make them. Backlog reprioritization works best when the team can discuss those trade-offs inside regular 2-week sprints.
A partner adds more value when technical input challenges assumptions or exposes consequences before a ticket reaches implementation. The Product Manager can retain ownership of product priorities without becoming the translation layer for every engineering decision.
Selleo positions delivery as a product and technology partnership in which engineering input supports prioritization rather than simply processing Jira tickets, following Agile delivery with 2-week sprints and reviews.

7. How Will I See Progress During Software Development?
Progress needs to be inspectable. Status reports and percentage-complete estimates can be useful, but they do not replace working increments, blockers, changed assumptions, emerging risks, and timeline details showing key milestones and expected completion dates. You need enough visibility to understand what is moving, what is blocked, and what has changed.
Scrum formalizes transparency, inspection, and adaptation, although Scrum is not required for every project. Similarly, DORA's delivery metrics provide useful measurement vocabulary rather than universal vendor-selection thresholds. A practical agile software development approach makes feedback possible while there is still time to change direction, and project management tools can make these checkpoints visible without relying only on percentage-complete reports.
Selleo describes clear estimates, weekly demos, and early risk flags as parts of its delivery approach. That is more useful evidence of transparency than the statement “we work Agile” on its own.

8. What Do You Need From Me as Project Manager?
A good answer defines where the Product Manager's input is necessary. Typical areas include prioritization, access to domain knowledge, stakeholder input, and timely product decisions. Both sides need to understand how much time, feedback, and decision-making the Product Manager will need to provide throughout delivery.
The important distinction is between product ownership and vendor coordination. The Product Manager can remain responsible for priorities without relaying every business question to developers and every technical question back to stakeholders. That distinction helps reveal whether the engagement model supports the PM’s day job or turns them into a full-time coordinator.
Direct communication between the people making product decisions and the people implementing them reduces unnecessary translation layers.
9. How Does Your Development Process Handle Scope Changes?
Scope changes need a visible decision path toward the right solution. Ask who approves them, how they affect the backlog, and how the vendor communicates the consequences for estimates or timelines.
The commercial model changes how those consequences are handled. A detailed comparison of fixed price vs time and material can help when choosing the model, but neither approach is universally safer. Early research or discovery can reduce avoidable scope churn before implementation starts. Requirement maturity and uncertainty matter.
Selleo supports different delivery and commercial models so the engagement can reflect the level of uncertainty and risk rather than forcing every project into one structure.

10. How Will You Communicate Blockers, Risks, and Decisions?
Communication quality is not measured by meeting volume. Ask who the main point of contact will be, whether a dedicated project manager owns escalations and updates, how decisions are recorded, and how quickly material risks become visible. The people who can act on a risk need to see it early enough to respond.
Agree upfront on communication and project-tracking channels such as Slack or Jira. Communication expectations also depend on the collaboration model. A software development company in the US may appear attractive for geographical reasons, but location alone does not establish effective access, escalation, or decision-making. Those mechanisms still need to be verified, and the team should be ready to talk through blockers, risks, and decisions clearly.
A mature delivery team exposes material risks early and lets clients contact the right people directly when blockers or risks need explanation.

More Questions Before You Choose the Right Software Development Company
The final five questions cover risks that become expensive after commitment: quality, security, commercial change, relationship fit, and the ability to leave. This is also where capabilities such as an MVP development company can be relevant when the immediate objective is validating a bounded product scope. The evaluation still needs to focus on evidence, not the service label.
11. How Do You Handle Quality Control and Code Review?
Ask who owns quality and how the team builds it into delivery. Useful answers cover code review, testing responsibilities, defect handling, manual QA, and where automated testing catches regressions earlier. They should also make clear when quality issues become visible.
A vendor cannot prove quality by quoting an arbitrary test-coverage percentage. When deeper validation is needed, software quality assurance services can provide additional testing capability. Quality still needs to remain part of delivery rather than a final gate before release. Ask for examples of how review and testing practices have prevented defects on similar work.
Strong teams treat quality as shared delivery accountability, with engineering and QA practices integrated throughout the work.

12. What Secure Software Development Practices Do You Follow?
Security needs concrete practices, not a statement that the vendor takes it seriously. NIST's Secure Software Development Framework provides recognized vocabulary for discussing secure development with suppliers, but referring to the framework does not prove that a vendor is secure or certified. The conversation also needs to cover the concrete controls the vendor will implement.
A Product Manager does not need to conduct a security audit during the first vendor conversation. The discussion can begin with evidence around:
- how security requirements enter development;
- how responsibilities for secure implementation and review are assigned;
- how vulnerabilities and security issues are handled;
- how relevant product or regulatory constraints affect delivery;
- whether NDA/BAA agreements are available upon request for confidentiality;
- how licensing terms and usage rights will be agreed before development starts.
These prompts turn a broad security promise into practices that can be investigated further.
Selleo's portfolio includes work on Catalyst, a HIPAA-compliant communication platform, which provides a concrete example of delivery in a context with security and compliance requirements. Selleo is ISO/IEC 27001 certified, implements ISO 22301 for business continuity management, and follows ISO-aligned security practices in development, which are useful points to verify. Protecting IP and confidentiality is crucial enough to validate early, because a relevant case demonstrates contextual experience but does not prove that every future project automatically meets the same requirements.
13. How Are Estimates, Billing Practices, and Commercial Changes Handled?
Ask how an estimate is produced, which assumptions and exclusions it contains, and what events trigger a change to cost or timeline. An estimate that hides uncertainty behind a precise number can make comparison harder rather than easier.
Commercial terms deserve their own due diligence. Guidance on IT outsourcing contracts can provide useful context for contractual topics, but project uncertainty still determines which commercial arrangement fits the engagement. The mechanism for handling change matters as much as the initial price.
A credible commercial model makes assumptions and change consequences visible instead of pretending that uncertain work is fully predictable.

14. Can We Test the Partnership With a Bounded Pilot Before a Larger Commitment?
A bounded engagement can provide evidence that a presentation cannot. It can reveal communication patterns, decision speed, technical judgment, and how both teams work through real ambiguity. Supporting case-study articles, when available, can help validate those signals. A pilot can also show whether the team’s training, communication habits, and working style hold up in real delivery rather than in a sales call.
The scope needs to be meaningful enough to test collaboration without assuming that every project benefits from the same pilot format. Selleo has used trial-based engagement as one way to let prospective clients evaluate working behavior before making a broader commitment.
A pilot is most useful when it tests real collaboration and produces evidence for the larger decision, rather than functioning as a disguised sales demo.
15. Who Owns the Code, Accounts, and Knowledge if Our Partnership Ends?
Legal ownership and practical portability are different questions. Contractual IP rights matter, but exit planning also needs to cover post-deployment support responsibilities after launch. Another competent team needs enough access and operational knowledge to continue the product.
Practical handover needs to account for assets such as:
- source-code repositories and relevant permissions;
- cloud, deployment, and service accounts;
- technical and operational documentation;
- third-party dependencies and access requirements;
- knowledge transfer needed to operate and maintain the software.
Software developers should also clarify maintenance contracts, update policies, and other ongoing support needed to keep the software functional post-launch.
For example, a product such as the microlearning platform built with Qstream involves more than source code alone when thinking about long-term product continuity. The same principle applies to any substantial software system: ownership without usable access and knowledge can still create dependency.
A healthy software partnership should make it possible for the client to stay because the relationship works, not because leaving has become technically difficult.
A healthy engagement leaves the client with enough control, documentation, transferable knowledge, and support services such as updates and maintenance policies for another competent team to continue the product without reconstructing its operating context from scratch.
After the interviews, turn the answers into a decision process rather than relying on overall impressions:
- Collect each vendor's answer to the same core questions.
- Verify important claims with relevant evidence.
- Record material risks or assumptions that remain unresolved.
- Compare the evidence across vendors without assigning an arbitrary score.
- Use the remaining uncertainty to decide whether the next step is further diligence, a bounded pilot, or contract discussion.
This sequence keeps a persuasive presentation from outweighing unresolved delivery or commercial risk.
A simple worksheet makes the comparison reusable:
The strongest comparison is not the vendor with the most polished answers. It is the comparison that makes evidence and unresolved risk visible enough for an informed decision.

Make the Final Decision Based on Evidence, Not the Sales Pitch
The purpose of these questions is not to find a software development company with a perfect answer to everything. It is to understand how the team actually works before product delivery, budget, and roadmap commitments are made.
The strongest development partner should be able to turn its promises into evidence: relevant people, a transparent delivery process, clear responsibilities, visible risks, sensible commercial terms, and a practical path to ownership and handover. When those elements can be verified, the final decision depends less on the quality of the sales presentation and more on how the partnership is likely to work once development begins.
