Hiring an app development company is an important step, but it is only the beginning of the project.
Once you sign the agreement, the development team does not normally jump straight into coding. First, they need to understand your business, your customers, the problem you want to solve, and what the app actually needs to do.
After that, the project moves through several stages. These usually include requirement planning, UI/UX design, development, testing, launch preparation, app store submission, and post-launch support.
As the client, you are involved throughout this process. You review designs, answer business questions, provide feedback, test important features, and approve key decisions.
Understanding this process helps you know what to expect after hiring an app development company. More importantly, it helps you avoid confusion about timelines, responsibilities, revisions, and the final delivery.
1. The Project Starts With a Kickoff Meeting
After the agreement is signed, the first important step is usually a project kickoff.
This meeting allows you and the app development company to establish a shared understanding of the project.
Depending on the size of the company, you may meet a project manager, UI/UX designer, mobile developer, backend developer, and quality assurance specialist.
However, the meeting is not mainly about introducing the team. Its real purpose is to make sure everyone understands what is being built.
The development company may ask about your business, target customers, competitors, goals, required features, preferred platforms, and expected launch date.
For example, suppose you want to build an appointment booking app for a clinic. The team needs more information than simply knowing that patients should be able to book appointments.
They may need to understand whether patients can choose doctors, reschedule appointments, make online payments, receive reminders, upload reports, or attend video consultations.
Therefore, the kickoff meeting helps turn your initial idea into a project that the development team can properly plan.
2. Your App Idea Is Converted Into Clear Requirements
Most business owners start with an idea rather than a complete technical specification.
You might say:
“I want an app where customers can book home cleaning services.”
That explains the basic concept, but developers need more detail before they can build it.
For example, should customers create accounts? Can they choose a service provider? Will pricing be fixed or calculated automatically? Can customers pay through the app? What happens if they cancel a booking?
The development company works with you to answer these questions.
As a result, your general idea gradually becomes a clear list of features and user actions.
For a service-booking application, the requirements might include customer registration, service selection, available time slots, booking management, online payments, notifications, customer support, and an admin system.
However, not every possible feature should automatically be included.
A good development team should help identify which features are necessary for the first version and which ones can wait.
This prevents the initial app from becoming unnecessarily large, expensive, and difficult to launch.
3. The Team Defines the First Version of Your App
Once the requirements are understood, the company usually defines the scope of the first release.
This stage is especially important for startups and businesses launching a new digital product.
You may have dozens of ideas for the app. However, trying to build all of them at once can increase development time and cost.
Instead, the team may recommend starting with the features needed to solve the main customer problem.
This first practical version is often called an MVP, or Minimum Viable Product.
For example, imagine you are building a restaurant ordering app.
The first version may need customer registration, restaurant menus, a shopping cart, online payment, order status, and notifications.
Features such as loyalty points, advanced recommendations, social sharing, subscriptions, and complex analytics could be introduced later.
The goal is not to create a poor or unfinished product.
Instead, the goal is to launch a focused version that customers can actually use.
Once real users begin using the app, their behavior and feedback can help guide future development.
4. You Receive a Project Plan and Timeline
After defining the scope, the development company can create a more realistic project plan.
The plan usually divides the work into stages or smaller development cycles.
For example, the team may first work on authentication and user profiles. After that, it might develop the main service features, payments, notifications, and the admin system.
A project manager normally coordinates these activities and keeps track of progress.
However, app development timelines are not always fixed from the first day.
Changes in requirements, delayed feedback, third-party integrations, technical problems, or additional features can affect the schedule.
Therefore, a professional company should communicate changes rather than silently missing deadlines.
As a client, you should know what is currently being developed, what is waiting for approval, and what comes next.
Clear communication becomes especially important when several people are involved in the project.
5. UI/UX Design Usually Comes Before Full Development
Before developers build the complete application, designers normally work on how the app should look and behave.
This is the UI/UX design stage.
UI, or User Interface, covers the visual parts of the application. These include buttons, colors, typography, cards, menus, icons, and screens.
UX, or User Experience, focuses on how easily users can complete tasks inside the app.
For example, imagine an appointment booking application.
A user might open the app, choose a doctor, select an available date, choose a time, confirm the appointment, and receive confirmation.
The designer needs to make this process simple and understandable.
If users need to move through too many screens or cannot find the booking button, the experience becomes frustrating.
You will normally review the design
The company may first show you wireframes or basic screen structures.
After the overall flow is approved, the team can create more detailed visual designs.
At this stage, you should review important areas carefully.
Check whether the design matches your business, whether important actions are easy to find, and whether the user journey makes sense.
It is usually easier to change a design before development begins than to rebuild a completed feature later.
Therefore, giving clear feedback during the design stage can save both time and money.
6. The Development Team Starts Building the App
Once the main designs and requirements are ready, development begins.
This is where developers turn approved designs into a working application.
However, development involves much more than creating visible screens.
A modern app may require mobile development, backend services, databases, APIs, authentication, notifications, payments, file storage, analytics, and an admin dashboard.
For example, when a customer taps Book Now, several things may happen behind the scenes.
The application may check availability, send information to a server, create a booking in the database, process a payment, update the provider’s schedule, and send a confirmation notification.
The user sees one button.
Behind that button, several systems may be working together.
Frontend development
The frontend is the part users directly interact with.
Developers build screens, navigation, forms, buttons, animations, and other visible parts of the application.
They also connect these screens to backend services.
Backend development
The backend handles much of the application’s data and business logic.
For example, it may manage user accounts, bookings, payments, products, orders, and notifications.
Some applications require a large custom backend. Others can use existing cloud services for many of these functions.
The technical approach depends on the requirements of the project.
7. You Should Receive Progress Updates During Development
You should not have to wait until the end of the project to see your application.
A professional development process usually includes regular progress updates.
Depending on the project, the company may provide weekly meetings, development builds, demonstrations, progress reports, or access to a project management system.
These updates allow you to see what has been completed.
More importantly, they give you an opportunity to identify misunderstandings early.
For example, imagine the team develops a booking process differently from what your business requires.
Finding that problem during an early demonstration is much better than discovering it immediately before launch.
Therefore, review the app when the development company asks for feedback.
Delayed feedback can slow down the entire project because developers may need your approval before continuing with related features.
8. Features Are Tested as They Are Developed
Testing should not happen only after every feature has been completed.
Instead, developers and testers should check features throughout the development process.
For example, when the login system is completed, the team can test successful login, incorrect passwords, password recovery, invalid input, and other important situations.
Similarly, a payment feature should be tested for successful payments, failed payments, cancellations, and unexpected responses.
This approach helps identify problems earlier.
As a result, bugs are usually easier to understand and fix.
9. The Complete App Goes Through Quality Testing
Once the main features are connected, the application requires broader testing.
The goal is to make sure the entire product works correctly rather than checking only individual screens.
Testers may examine navigation, forms, user accounts, payments, notifications, API responses, permissions, error handling, and other important functions.
Mobile apps also need testing across different devices and screen sizes.
For example, an interface that looks correct on a large phone may have layout problems on a smaller device.
Similarly, Android and iOS can behave differently in areas such as permissions, notifications, and background activity.
Real-world situations also matter
Testing should include more than the ideal user journey.
What happens when the internet connection disappears during a request?
What happens when a user taps a button twice?
What if the server returns an error?
What happens if payment fails after the user confirms an order?
These situations matter because real users will eventually encounter them.
A reliable app should handle errors clearly rather than simply freezing or crashing.
10. You Usually Get a Version to Review
Before the public launch, the company may provide a test or staging version of the application.
This gives you an opportunity to experience the app as a real user.
At this stage, you should test complete journeys rather than checking only individual screens.
For example, if you are building an e-commerce app, try creating a new account, finding a product, adding it to the cart, applying any available discount, completing payment, and checking the resulting order.
Then test other situations.
Try an incorrect password. Cancel a payment. Enter invalid information. Check notifications. Review the app on another device.
You understand your business better than the development team does.
Therefore, your testing can identify business-related issues that a technical tester may not immediately notice.
11. Feedback and Revisions Are Managed Before Launch
After reviewing the app, you may request changes.
However, there is an important difference between fixing a problem and adding a new requirement.
Suppose the approved design says a button should open the payment page, but the button does nothing.
That is clearly a bug.
On the other hand, suppose you decide that customers should now be able to split payments between two cards.
If this feature was never included in the agreed scope, it is a new requirement rather than a bug.
This distinction matters because additional features may require more design, development, testing, time, and budget.
Therefore, the development company should explain how change requests affect the project before implementing significant additions.
A clear change-management process helps avoid disagreements later.
12. The App Is Prepared for Launch
Once testing and final revisions are complete, the team prepares the application for release.
For mobile apps, this often includes preparing the Android and iOS production builds.
However, publishing an app requires more than uploading the application file.
The store listing may need an app name, description, screenshots, app icon, category, privacy information, support details, and other required information.
In addition, the app may need a privacy policy depending on the information it collects and the services it uses.
Your company should also confirm that production systems are ready.
For example, payment systems should use production credentials rather than test credentials.
Backend servers, databases, domains, analytics, notifications, and other services should also be configured correctly.
13. The App Is Submitted to the App Stores
For most consumer mobile applications, the next stage is submission to Apple’s App Store and Google Play.
The development company can usually help prepare and submit the application.
However, the business should ideally own the developer accounts used to publish its app.
This keeps important assets under the business’s control rather than permanently tying them to an outside development company.
After submission, the store reviews the application.
Approval is not always immediate.
A store may request additional information or reject an application because of technical, privacy, content, payment, or policy issues.
If this happens, the development team normally reviews the feedback, makes any necessary changes, and submits the app again.
Therefore, businesses should avoid planning an important marketing campaign around an exact launch time until store approval is confirmed.
14. Launch Day Is Not the End of Development
Publishing the app is an important milestone, but it does not mean the project is finished forever.
Once real customers begin using the application, new information becomes available.
Users may discover situations that were not seen during testing.
Some people may struggle with a particular screen. Others may request a feature that the original team did not consider important.
In addition, analytics may show where users leave the app or which features they use most often.
This information can help the business decide what to improve next.
Therefore, successful apps usually continue evolving after their first release.
15. Post-Launch Support and Maintenance Begin
Apps require ongoing maintenance because the environment around them continues changing.
Android and iOS receive updates. Third-party services change their APIs. Payment providers introduce new requirements. Libraries receive security updates. New device sizes appear.
As a result, an app that works perfectly today may eventually require changes.
Post-launch support can include bug fixes, compatibility updates, performance improvements, security updates, server monitoring, and small improvements.
However, support terms differ between companies.
Before the initial project ends, make sure you understand what support is included, how long it lasts, and what happens when you request additional development.
16. New Features Are Usually Planned in Future Versions
After the first release, businesses often begin planning the next version.
However, feature decisions can now be based on real user behavior rather than assumptions.
For example, suppose customers frequently add products to their carts but do not complete checkout.
Instead of immediately adding a completely unrelated feature, the business may investigate the checkout experience first.
Perhaps users find the payment process confusing.
Improving that existing experience could have more value than adding another large feature.
Similarly, customer feedback may reveal features that users genuinely need.
Therefore, the first release should be treated as the beginning of the product’s development rather than the final version.
What Should You Expect From the App Development Company?
Throughout the project, you should expect clear communication about progress, decisions, problems, and changes.
You should know who your main contact is and how often you will receive updates.
Moreover, important technical and business decisions should not come as surprises at the end of the project.
You should also understand what will be delivered when the project is completed.
Depending on the agreement, this may include source code, design files, production builds, backend access, documentation, store listings, and other project assets.
Make sure ownership and access are clearly defined in your contract rather than assuming everything will automatically be transferred.
What Does the App Development Company Need From You?
The development company handles the technical work, but the client still has important responsibilities.
First, provide clear information about your business and customers.
Next, review designs and development builds when requested.
You may also need to provide brand assets, business information, legal documents, product content, third-party account access, or payment-provider details.
Most importantly, provide feedback on time.
For example, if the development team needs approval for the checkout design and waits two weeks for your response, later development may also be delayed.
Fast decisions do not mean approving everything without reviewing it.
Instead, they mean keeping communication active so the project can continue moving.
Questions to Ask During Development
You do not need to understand every technical detail. However, you should understand the status of your project.
Useful questions include:
- What has been completed?
- What is currently being developed?
- What do you need from me?
- Are we still within the agreed scope?
- Has anything affected the timeline?
- When can I test the next version?
- Are there any technical risks I should know about?
- Who owns the source code and accounts?
- What happens after the app launches?
These questions keep conversations focused on the information that matters to the business.
Common Mistakes Clients Should Avoid
One common mistake is changing the core requirements repeatedly after development has started.
Small changes are normal. However, major changes can affect several connected parts of the application.
Another mistake is delaying feedback.
If the development team continues working based on an incorrect assumption, fixing it later can require more work.
Businesses should also avoid treating testing as the development company’s responsibility alone.
The technical team understands software, but you understand your business processes and customers.
Therefore, both sides should participate in reviewing the product.
Finally, do not wait until launch day to ask about source code, developer accounts, hosting, domains, analytics, or third-party services.
These responsibilities should be clear much earlier.
How Long Does the Whole Process Take?
There is no single development timeline that applies to every app.
A simple application with a few screens and basic features can take much less time than a marketplace, healthcare platform, delivery service, or complex business application.
The timeline depends on factors such as the number of features, supported platforms, backend complexity, third-party integrations, design requirements, testing needs, and client feedback.
Moreover, adding features during development can extend the schedule.
Therefore, businesses should be careful with companies that promise an exact timeline before properly understanding the requirements.
A useful estimate should be based on a clearly defined scope.
What Happens If You Want Changes After Launch?
Changes after launch are completely normal.
You may want to improve an existing feature, add a new service, redesign part of the app, or integrate another business system.
Usually, the development company reviews the new requirement first.
After that, it can estimate the work, timeline, and cost.
Small changes may be included in an existing maintenance agreement. However, larger features are normally treated as new development work.
For example, fixing a broken payment button may be maintenance.
Adding an entirely new subscription system would usually be a separate feature.
Understanding this difference helps businesses plan future development budgets more realistically.
Frequently Asked Questions
Do developers start coding immediately after I hire an app development company?
Usually, no. The team first needs to understand your requirements, users, features, and project scope. Design and technical planning may also happen before full development begins.
Will I be involved during app development?
Yes. Clients normally review designs, provide business information, give feedback, test development builds, and approve important decisions.
Can I change features during development?
Yes, but significant changes can affect the budget and timeline. Therefore, the company should explain the impact of a new requirement before implementing it.
Who publishes the app?
The development company can usually help prepare and submit the app. However, your business should generally maintain control of its own developer accounts and important production assets.
What happens after my app is launched?
The team may provide maintenance, bug fixes, compatibility updates, monitoring, and further development depending on your agreement. User feedback can also guide future improvements.
Will I receive the source code?
That depends on your contract. Source-code ownership, design files, account access, and other deliverables should be clearly agreed upon before or during the project.
Do I need ongoing app maintenance?
Most production apps require some ongoing maintenance. Operating systems, devices, APIs, libraries, security requirements, and business needs continue changing after launch.
Conclusion
Hiring an app development company starts a process rather than completing one.
The project normally begins with understanding your business and defining clear requirements. After that, the team plans the product, designs the user experience, develops the application, tests its features, and prepares it for launch.
Your involvement remains important throughout these stages.
Clear feedback during design can prevent expensive changes later. Regular testing can uncover business problems before launch. In addition, clear ownership of accounts, code, and other assets can prevent complications after the project ends.
Once the app reaches real users, development often continues through maintenance, improvements, and new features.
Therefore, a successful app project is not simply about hiring developers to write code. It is a structured collaboration between your business and the development team, with both sides working toward a product that solves a real problem for its users.
