You’ve found a software development agency. The proposal looks professional, the timeline sounds reasonable, and the team seems confident. But how do you know what you’re actually signing up for?
Most founders evaluate agencies based on portfolios, pricing, and delivery promises.
Those things matter. But they rarely tell you what happens when development gets complicated.
What if the application struggles when your customer base grows? What if the developer responsible for your product leaves? What if you discover that your company doesn’t own the source code?
These aren’t unusual technical problems. They’re business risks that should be addressed before signing a software development agency contract.
Here are 15 questions worth asking before you commit.
1. Who Will Own the Source Code?
Ask: Will our company have full ownership of the source code, repositories, and technical documentation?
Your contract should clearly establish intellectual property ownership, including any conditions attached to final payment.
Founder insight: Paying for software doesn’t automatically mean you own every component. Clarify third-party licenses, reusable agency components, and ownership transfer terms.
2. Who Controls the Hosting and Cloud Accounts?
Ask: Will our infrastructure run under accounts owned by our company?
If your agency controls the only administrator account, switching providers could become difficult.
Ideally, your business should own its cloud, domain, and critical service accounts, while granting the agency appropriate access.
3. How Will You Decide the Technology Stack?
Ask: Why are you recommending these technologies for our specific product?
A good agency should explain its choices based on product requirements, expected usage, maintenance, available talent, and budget.
Be cautious when every project receives the same technology recommendation without a clear explanation.
4. What Happens When Our User Base Grows?
Ask: How will the architecture handle increasing users, transactions, and data?
A product serving 500 users may behave differently when 50,000 people depend on it.
Ask which components are likely to become bottlenecks and how the team plans to identify them.
Founder insight: Scalability doesn’t mean building expensive infrastructure immediately. It means avoiding decisions that make future growth unnecessarily difficult.
5. How Will You Protect Customer Data?
Ask: What security practices will be implemented during development and deployment?
Discuss access controls, encryption, secure authentication, dependency updates, vulnerability management, and backup protection.
For healthcare or financial products, ask how applicable regulatory requirements will be identified and addressed.
Security shouldn’t be something you discuss only before launch.
6. How Will You Test the Software?
Ask: What testing happens before a feature is considered complete?
Look for a combination of automated tests, integration testing, manual quality assurance, and testing of critical user journeys.
Ask whether failed tests block a release.
A feature that works during a demonstration isn’t necessarily production-ready.
7. Who Makes Technical Decisions?
Ask: Who is accountable for architecture, security, and major engineering trade-offs?
A project manager may coordinate delivery without having the authority or expertise to evaluate complex technical decisions.
Understand who the technical lead is and how important decisions are reviewed.
8. How Will We Track Development Progress?
Ask: Can we review working software throughout development?
Request regular demonstrations, access to a shared project tracker, and visibility into completed versus pending work.
Progress shouldn’t be measured only through status reports or percentages.
Founder insight: A working feature demonstrated every two weeks provides stronger evidence of progress than a slide saying development is 80% complete.
9. What Happens When Requirements Change?
Ask: How are scope changes evaluated, priced, and approved?
Product requirements evolve, especially during MVP development.
Your contract should define how changes affect cost, timeline, and deliverables.
Without a documented change-control process, small requests can become expensive disagreements.
10. How Will You Prevent Vendor Lock-In?
Ask: Could another development team maintain this product if we stopped working together?
Discuss documentation, repository access, infrastructure configuration, third-party dependencies, and knowledge transfer.
A healthy agency relationship shouldn’t depend on making it difficult for you to leave.
11. What Documentation Will We Receive?
Ask: What technical documentation is included in the delivery?
At minimum, consider architecture diagrams, deployment instructions, API documentation, environment configuration, and operational procedures.
Documentation should be updated as the product changes, not rushed during the final week.
12. How Will Deployments and Rollbacks Work?
Ask: What happens if a software update breaks production?
Ask about staging environments, deployment approvals, automated pipelines, monitoring, and rollback procedures.
Reliable delivery means having a plan for when something goes wrong, not assuming every release will succeed.
13. What Are the Ongoing Maintenance Costs?
Ask: What will this software cost to operate after launch?
Development fees are only part of the investment.
Request estimates for hosting, third-party APIs, monitoring, security updates, bug fixes, and ongoing support.
A cheaper initial quote may result in higher long-term operating costs.
14. What Happens After the Product Launches?
Ask: What support, warranty, and incident-response commitments are included?
Clarify which defects will be fixed without additional charges, how quickly critical incidents receive attention, and when ongoing maintenance becomes a separate service.
Make sure the support terms match your product’s business requirements.
15. How Will We Know the Project Is Successfully Delivered?
Ask: What measurable criteria must be met before final acceptance?
Define acceptance criteria for features, performance, security, documentation, and deployment.
For example, rather than accepting “fast application performance,” agree on measurable performance targets under defined test conditions.
Founder insight: Clear acceptance criteria protect both the founder and the development agency by making expectations testable.
The Questions Matter. So Do the Answers.
You don’t need to be a software engineer to evaluate a development partner.
You do need to understand who owns the product, who makes critical decisions, how delivery is verified, and what happens when things don’t go according to plan.
Pay attention to how agencies respond.
A reliable partner should be willing to explain trade-offs, acknowledge uncertainty, and document important commitments.
If an agency cannot clearly explain how your software will be built, secured, maintained, and handed over, don’t sign until those questions are resolved.
At Enlight Lab, we help founders evaluate technical decisions, plan software architecture, and manage product development with experienced technical leadership.
Whether you’re preparing to build an MVP or reviewing an agency proposal, our Fractional CTO services can help you understand the risks before making a major investment.

Frequently Asked Question (FAQ)
Review intellectual property ownership, project scope, deliverables, payment milestones, security responsibilities, acceptance criteria, maintenance terms, and termination provisions. Have a qualified legal professional review the contract where appropriate.
Ask the agency to explain its architecture, testing process, security approach, and delivery milestones in plain language. An independent CTO or technical advisor can help validate the answers.
For custom software, founders should generally negotiate ownership or sufficient rights to use, modify, and maintain the delivered code. The agreement must also address third-party and pre-existing components.
Common risks include unclear requirements, weak quality assurance, poor communication, inadequate security, vendor lock-in, unexpected costs, and insufficient technical documentation.
Yes. A Fractional CTO can review proposals, evaluate technical architecture, assess development practices, clarify delivery expectations, and help founders make informed vendor decisions without hiring a full-time CTO.
