Most sales calls with an app development agency go the same way. They show a polished deck, walk through a few case studies, and hand you a proposal. What rarely happens on that call is you asking the questions that actually determine whether the project goes well or turns into a six-month headache.

The agency has done this pitch dozens of times. You’re likely doing it for the first time, or the first time in a while. That imbalance is exactly why having a specific list of questions matters more than a general sense of whether you “liked” the team.

This post is a practical, question-by-question guide. If you’ve already read our post on how to choose the right Android app development company, think of this as the follow-up: the actual script for your first real conversation.

Questions About the Team That Will Work on Your Project

Agencies often pitch with their most senior people in the room, then staff the actual project with someone else entirely. Ask directly who will be assigned to your build, not just who’s on the sales call.

• Who specifically will be writing the code for our app?
• What’s their experience level, and have they shipped apps of similar complexity before?
• Will the same team stay on the project from start to finish, or does staffing rotate?
• Is any part of the work outsourced to a third party or subcontractor?
• Who is our single point of contact for updates and questions?

Why this matters: – A team swap midway through a project is one of the most common causes of delays and quality drops. Locking this down early gives you something concrete to hold the agency to later.

Questions About Their Technical Approach

This is where you separate an agency that genuinely understands Android development from one that’s comfortable talking around it.

• Will you build native (Kotlin/Java) or cross-platform (Flutter/React Native), and why is that the right call for our app?
• How will you handle backend architecture, and who owns that infrastructure once the project ends?
• What’s your approach to third-party integrations and APIs our app will depend on?
• How do you handle Android device and OS fragmentation during testing?
• What security practices do you follow for handling user data?

A Quick Way to Read the Answers

Vague, high-level answers here are a warning sign. A capable agency should be able to explain their reasoning in terms specific to your app, not repeat a generic list of technologies.

Questions About Their Process and Timeline

Ask them to walk through their process step by step, then compare what they describe against what actually shows up in the contract.

• What does your development process look like from kickoff to launch?
• How do you gather and document requirements before development starts?
• What’s a realistic timeline for a project like ours, and what could push that timeline out?
• How often will we get updates, and in what format?
• What happens if we want to change or add a feature mid-project?

What is a scope change process, and why should you ask about it?

A scope change process is how an agency handles new requests or feature changes once development has already started. Without a clear process, small changes can quietly balloon into missed deadlines and unexpected costs. Asking about this upfront protects both your budget and your timeline.

Questions About Pricing and What’s Actually Included

Pricing conversations often stay surface-level unless you push for specifics. Get clarity on what the number in the proposal actually covers.

• Is this a fixed-price, dedicated-team, or time-and-materials engagement?
• What exactly is included in this price, and what would trigger an additional cost?
• Are design, testing, and Play Store submission included, or billed separately?
• What payment milestones do you use, and what triggers each one?
• Do you offer a written contract with defined deliverables, not just a verbal agreement?

Questions About Testing and Quality Assurance

Testing is where corners get cut most often when an agency is trying to hit a deadline or a price point. Ask specifically how they handle it.

• What’s your QA process before an app goes live?
• Do you test across multiple Android devices and OS versions, or just one or two?
• How do you handle bugs discovered during testing versus after launch?
• Will we get access to a beta or staging version before the final release?

Questions About Launch and Play Store Submission

Getting an app built is only part of the job. Getting it approved and live on the Play Store is its own process, with its own potential delays.

• Who handles the Google Play Store submission and listing setup?
• Have you run into Play Store rejections before, and how did you resolve them?
• Do you help with app store optimization, like listing copy and keywords, or is that separate?
• Who owns the Play Store developer account once the app is live, us or you?

Questions About Post-Launch Support and Maintenance

This is the question most first-time buyers forget to ask, and it’s often where the real cost of a cheap-looking proposal shows up later. Our own Android app development process treats this as a standard part of the engagement rather than a separate upsell, and it’s worth confirming the same from any agency you’re evaluating.

• Is post-launch support included, or is it a separate contract?
• How do you handle compatibility issues when Android releases a new OS version?
• What’s your average response time for a bug reported after launch?
• Do you offer an ongoing maintenance plan, and what does it cover?

Questions to Ask Their Past Clients

The agency’s answers only tell you half the story. Ask for a reference, and come prepared with your own questions for that call.

• Did the project stay on budget and on schedule?
• How did the agency communicate when something went wrong?
• Would you hire them again for a second project?
• Is the app they built still live, and can I download it?

Red Flags in How an Agency Answers These Questions

Pay attention not just to what they say, but how they say it. A few patterns are worth taking seriously:

• Answers stay vague even after you ask a follow-up question
• Pricing details are avoided until you push for specifics
• They can’t name who will actually work on your project
• Testing and post-launch support only come up if you bring them up first
• They pressure you to sign before you’ve had time to check references

Take Action: Bring This List to Your Next Call

Print or save this list before your next agency conversation. Go through it question by question rather than letting the agency control the flow of the call, and take notes on both what they say and how confidently they say it. If you’re comparing multiple agencies, ask every one of them the exact same questions so the answers are actually comparable side by side.

You can also look into what it takes to hire Android developers directly if a dedicated team fits your situation better than a full agency engagement, or explore our approach to custom mobile app development more broadly.

Frequently Asked Questions

Q: – What’s the single most important question to ask an Android app development agency?

A: – Who specifically will work on your project, and what’s their direct experience. Vague answers here tend to predict vague answers everywhere else.

Q: Should I ask for a written contract before starting a project?

A: – Yes. A written contract with defined deliverables, timelines, and payment milestones protects both sides and gives you something concrete to point to if the project drifts off track.

Q: How many agencies should I interview before making a decision?

A: – Three to five is a reasonable range. It’s enough to compare answers meaningfully without dragging the decision out for weeks.

Q: What should I do if an agency won’t share client references?

A: – Treat it as a serious warning sign. Established agencies are typically glad to connect you with past clients, since a reference call works in their favor when the project went well.

Q: – Is it normal for pricing to change after the initial proposal?

A: – Some change is normal if your requirements shift, but the agency should have a clear process for how that’s handled and communicated, not open-ended cost creep.

Q: Should I ask about the technology stack even if I’m not technical?

A: – Yes. You don’t need to understand every detail, but you should expect an answer you can follow, one that explains why a technology choice fits your specific app.
