Hiring a developer or software development company is only the first step toward building a website, mobile app, or custom software product.
Before development begins, the developer needs to understand exactly what you want to build, who will use it, what problem it should solve, and which features are actually important.
You do not need to prepare a complicated technical document. In fact, you do not even need to know which programming language, database, or framework should be used.
What developers need from you is clear business information.
For example, saying, “I need a mobile app for my clinic” gives a developer only a basic idea. However, explaining that patients should find doctors, view available time slots, book appointments, receive reminders, and manage upcoming appointments gives the developer something they can actually plan.
Providing the right information at the beginning can reduce misunderstandings, unnecessary revisions, unexpected costs, and development delays.
This guide explains exactly what information you should give a developer before starting a software project.
1. Start by Explaining Your Business
Before explaining individual features, help the developer understand your business.
This context matters because the same type of software can work very differently for different companies.
For example, two businesses may both ask for an appointment booking system.
A small salon may need a simple system where customers choose a service, employee, date, and time.
A healthcare clinic may need doctor profiles, patient accounts, appointment types, reminders, medical information, and stricter privacy requirements.
Therefore, start with a simple explanation of what your business does.
Tell the developer what products or services you provide, how customers currently interact with your business, and where the new software fits into that process.
You could explain:
“We run a home cleaning company. Customers currently contact us by phone or WhatsApp. We want an app where they can choose a cleaning service, select a date and time, see the price, and make a booking.”
A short explanation like this immediately gives the developer useful context.
2. Explain the Problem You Want to Solve
This is one of the most important pieces of information you can provide.
Do not focus only on what you want developers to build. Explain why you need it.
For example, instead of saying:
“We need a customer portal.”
Explain the actual problem:
“Customers currently email us whenever they need an invoice or want to check their project status. We want a portal where they can log in and access this information themselves.”
Now the developer understands the purpose behind the feature.
This can lead to better decisions during planning.
For instance, the developer may realize that customers need invoice downloads, project updates, notifications, and account management rather than a complicated portal with dozens of unnecessary features.
When developers understand the problem, they can help design a more appropriate solution.
3. Clearly Describe What You Want to Build
Next, explain what type of product you have in mind.
It could be a business website, e-commerce store, customer portal, mobile app, web application, internal dashboard, booking platform, marketplace, or custom software system.
You do not need to know the exact technical architecture.
Instead, explain what you expect customers or employees to use.
For example:
“We need a mobile app for customers and a web dashboard for our staff.”
That single sentence already provides useful information.
The developer now knows there may be at least two interfaces: a customer-facing mobile application and an internal management system.
If you are unsure whether you need a website, web application, or mobile app, explain the business requirement instead of guessing the technology.
A good developer should help you evaluate the appropriate solution.
4. Explain Who Will Use the Product
Developers need to know who the users are because different users often require different features and permissions.
For example, imagine you are building a property rental application.
The system might have tenants, property owners, agents, and administrators.
Each user may need a different experience.
A tenant might search for properties and contact an agent.
An owner might upload property details and manage listings.
An agent might respond to enquiries.
Meanwhile, an administrator may manage users, listings, reports, and payments.
Therefore, tell the developer about every important type of user.
This is commonly called defining user roles.
For a marketplace, the roles could be customers, sellers, delivery staff, and administrators.
For a school platform, they might be students, teachers, parents, and administrators.
Clearly identifying these users helps developers understand how the complete system should work.
5. List the Main Features You Need
You should provide a basic list of the features you believe are important.
Do not worry about writing technical specifications.
Simply describe what users should be able to do.
For example, a service-booking application might need account registration, service selection, appointment scheduling, online payments, booking history, notifications, reviews, and customer support.
However, avoid adding features simply because other apps have them.
Ask yourself:
Does this feature help solve the main problem?
If the answer is no, it may not be necessary for the first version.
This is especially important when your budget or timeline is limited.
Building fewer useful features properly is often better than creating a large application filled with features customers rarely use.
6. Separate Essential Features From Future Ideas
Not every idea needs to be included in the first release.
Therefore, divide your requirements into two groups: features you need now and features you may want later.
Imagine you are building a fitness application.
The first version may require user accounts, workout plans, exercise videos, progress tracking, and notifications.
Later versions could add social challenges, wearable integrations, AI coaching, subscriptions, and advanced analytics.
This distinction helps developers estimate the initial project more accurately.
It can also prevent scope creep.
Scope creep happens when more and more features are added during development without properly adjusting the timeline or budget.
By identifying priorities early, you can keep the first version focused.
7. Describe the User Journey
A feature list tells developers what the product needs.
A user journey explains how those features connect.
Think about what happens from the moment a user opens your product until they complete an important action.
For example, consider a restaurant ordering app.
A typical journey might be:
A customer opens the app, creates an account, enters their location, finds a restaurant, selects food, adds items to the cart, enters a delivery address, chooses a payment method, places the order, and tracks its status.
This sequence helps developers understand how screens and features should work together.
You do not need to create professional flowcharts.
Simply describe important processes in the order they should happen.
If your business already follows an offline process, explain that too.
Developers can then understand which parts need to become digital.
8. Explain What Should Happen Behind the Scenes
Users see screens and buttons, but software often performs many operations behind those screens.
Therefore, tell the developer about important business rules.
For example, suppose a customer books a hotel room.
Should the room immediately become unavailable for other customers?
Can customers cancel the booking?
Is there a cancellation fee?
Can staff manually change the reservation?
Should the customer receive an email?
Should payment be refunded automatically?
These rules affect how the software needs to work.
Another example is a delivery application.
You may need rules about delivery areas, minimum order amounts, service charges, driver assignment, cancellations, refunds, and order status.
The developer cannot reliably guess these rules.
Therefore, explain important business logic before development begins.
9. Tell the Developer Which Platforms You Need
Make it clear where you expect the product to work.
For a mobile application, you may need Android, iPhone, or both.
For a website, users may access it through desktop computers, tablets, and mobile browsers.
Some businesses may also need an internal web dashboard in addition to a customer-facing app.
For example:
“Customers need Android and iPhone apps, while our employees will manage bookings through a web dashboard.”
This gives the development team a much clearer understanding of the project.
However, you do not necessarily need to decide which technology should be used.
Whether the application should use native development, Flutter, React Native, or another technology is usually a technical decision that can be discussed after the requirements are understood.
10. Share Examples of Apps or Websites You Like
Examples are extremely useful because words such as “modern,” “premium,” “simple,” and “professional” mean different things to different people.
Instead of saying:
“I want a modern app.”
Show the developer examples.
You might like the navigation of one application, the checkout process of another, and the visual style of a third.
Explain exactly what you like about each example.
For instance:
“I like how this app shows categories on the home screen.”
Or:
“I like this website’s clean product pages, but I don’t want its dark design.”
This helps designers understand your preferences without copying another company’s product.
References should be used for direction and inspiration, not duplication.
11. Provide Your Branding Information
If your business already has an established brand, provide the relevant assets before design work begins.
These may include your logo, brand colors, fonts, icon style, photographs, illustrations, and existing brand guidelines.
If you already have a website, social media pages, brochures, or marketing materials, these can also help designers understand your existing visual identity.
However, some businesses do not have complete branding yet.
That is fine.
Tell the development company early so it knows whether branding work needs to be included in the project.
Otherwise, design work may be delayed while everyone waits for missing assets.
12. Explain What Content You Already Have
A developer also needs to know who will provide the content.
For a business website, this may include page text, service descriptions, product information, photographs, videos, team profiles, FAQs, and contact information.
For an e-commerce application, you may need product names, descriptions, prices, categories, photographs, stock information, and shipping details.
Do not assume developers will automatically create all of this content.
Some development companies offer content creation, while others expect the client to provide it.
Clarifying this responsibility early can prevent delays later.
13. Mention Any Third-Party Services You Need
Modern applications frequently connect to other services.
Tell the developer if your product needs integrations such as online payments, maps, email, SMS, analytics, accounting software, customer relationship management systems, social login, video calling, shipping services, or existing business software.
For example, suppose your business already uses a particular CRM.
If the new app needs customer information from that system, the developer should know before designing the backend.
Likewise, if you need Stripe or another payment provider, this can affect the checkout process and development requirements.
You do not need to understand the technical API.
Simply tell the developer which services you currently use and which ones should communicate with the new product.
14. Explain Whether You Have an Existing System
Not every software project starts from zero.
You may already have a website, mobile app, database, backend, admin panel, or older software system.
If so, tell the developer.
The new project may need to reuse existing data or connect to an existing backend.
For example, a retailer may already have thousands of products stored in an inventory system.
Building a new e-commerce application without considering that system could create duplicate work.
The developer may need access to existing documentation, APIs, database information, or source code before recommending an approach.
However, never send passwords or sensitive credentials through an insecure message simply because a developer asks for access.
Use appropriate account permissions and secure sharing methods.
15. Tell the Developer About Login and User Accounts
Authentication can significantly affect a project.
Explain whether users need accounts and how you expect them to sign in.
For example, you might want email and password login, phone-number verification, Google sign-in, Apple sign-in, or another supported method.
Also explain what happens after registration.
Does a user need to verify their email?
Does an administrator approve new accounts?
Can users reset their passwords?
Can they delete their accounts?
Do different users receive different permissions?
These details help the development team plan authentication and account management correctly.
16. Explain Your Payment Requirements
If the project involves money, discuss payments early.
Tell the developer what users are paying for and how the payment process should work.
For example, are customers purchasing products, paying for appointments, subscribing monthly, paying deposits, or transferring money between users?
Also mention relevant business requirements such as currencies, refunds, taxes, invoices, discounts, and recurring payments.
The developer can then determine what payment functionality and integrations are required.
Importantly, payment processing can involve technical, financial, legal, and platform requirements.
Therefore, it should not be treated as a small feature added at the last minute.
17. Mention Notifications and Communication
Think about how your system needs to communicate with users.
You may require push notifications, emails, SMS messages, in-app notifications, or a combination of these.
For example, an appointment application could send a confirmation when a booking is created and a reminder before the appointment.
An e-commerce app might notify customers when an order is confirmed, shipped, and delivered.
However, sending too many notifications can frustrate users.
Therefore, explain which events actually require communication.
Developers can then design notification logic around real business needs.
18. Explain Whether You Need an Admin Panel
Many clients focus entirely on what customers will see.
However, someone also needs to manage the application.
That is often done through an admin panel.
For example, administrators may need to manage customers, products, bookings, orders, payments, categories, support requests, notifications, and reports.
Before development begins, explain what your employees need to control.
Consider a marketplace.
Customers may have a simple mobile app, but the business could require a much larger internal dashboard for approving sellers, reviewing products, resolving disputes, and monitoring transactions.
Therefore, the admin side should be treated as an important part of the project rather than an afterthought.
19. Explain Any Reports or Analytics You Need
Businesses often need information about how their software is being used.
For example, you may want to know how many customers registered, how many bookings were completed, which products sell most, or how much revenue was generated.
Tell the developer which information is important to your business.
Some data can be collected using analytics tools, while other reports may need to be built into the admin system.
Defining these requirements early helps ensure that the necessary data is collected from the beginning.
Otherwise, you may discover later that the information you want was never stored.
20. Discuss Security and Privacy Requirements
Security should be discussed before development, especially when the application handles personal or sensitive information.
Tell the developer what type of information the system will collect.
This may include names, email addresses, phone numbers, addresses, payment information, photographs, business documents, or location information.
Certain industries may also have additional legal or compliance requirements.
For businesses serving European users, for example, data protection requirements such as GDPR may need to be considered depending on the product and how personal data is processed.
You do not need to design the security architecture yourself.
However, developers need to know what type of information they are protecting so they can plan appropriate access controls, data handling, and security measures.
Legal requirements should also be reviewed with an appropriate legal or compliance professional when necessary.
21. Be Clear About Your Budget
Some clients avoid mentioning their budget because they worry it will increase the price.
However, a realistic budget range can help a development company recommend an appropriate solution.
Imagine two businesses requesting an online marketplace.
One has a budget for a focused MVP.
The other wants a large platform with mobile apps, advanced search, seller dashboards, subscriptions, analytics, automation, and multiple integrations.
Although the general idea is similar, the appropriate development approach may be completely different.
A budget helps determine what can realistically be included in the first version.
If the full idea exceeds your current budget, the developer can help prioritize essential features rather than designing something you cannot afford to complete.
22. Share Your Expected Timeline
Tell the developer if you have an important deadline.
For example, you may need the product before a conference, seasonal campaign, investor presentation, or business launch.
However, distinguish between a preferred date and a fixed deadline.
Saying, “It would be useful to launch around March” is different from saying, “The system must be ready before our event on March 15.”
This information helps the team plan the scope.
If the deadline is tight, some lower-priority features may need to move to a later version.
Be cautious about reducing testing simply to meet an unrealistic launch date. A smaller stable product is generally more useful than a larger product that does not work reliably.
23. Explain What Success Looks Like
Developers need to know what you are building, but it is also useful to explain what you hope the project will achieve.
For example, success might mean receiving more online bookings, reducing customer support calls, increasing online sales, replacing manual paperwork, or helping employees complete a process faster.
Consider a clinic that currently receives all appointments by phone.
The goal of its new booking application might be to allow customers to manage routine appointments without calling reception.
That objective influences design decisions.
If reducing phone calls is important, the app needs to make booking, rescheduling, cancellation, and common information easy to access.
Clear goals help the development team focus on outcomes rather than simply completing a list of features.
24. Clarify Who Makes Final Decisions
This becomes particularly important when several people from your company are involved.
For example, the business owner may approve the budget, the marketing manager may review design, and the operations manager may define business processes.
If each person provides conflicting instructions directly to developers, the project can quickly become confusing.
Therefore, establish who has final approval.
You can still collect feedback from multiple people. However, one person should normally communicate the final decision to the development team.
This makes approvals faster and reduces contradictory requests.
25. Tell the Developer How You Prefer to Communicate
Good communication can prevent many project problems.
Before development starts, agree on how updates will be handled.
You may prefer email, Slack, Microsoft Teams, video meetings, a project management platform, or another agreed channel.
Also decide how often progress should be reviewed.
For example, you might have a short weekly meeting and receive a test build whenever a major feature is completed.
The exact method is less important than consistency.
Both sides should know where questions, feedback, approvals, and important decisions will be recorded.
26. Discuss Ownership and Final Deliverables
Do not wait until the project is finished to ask what you will receive.
Discuss ownership before development begins.
Depending on the project and contract, final deliverables may include source code, design files, mobile application builds, backend code, documentation, database access, hosting information, and app store assets.
Your business may also need control over accounts for domains, cloud hosting, analytics, payment providers, Apple developer services, and Google Play.
These details should be written clearly in the agreement.
A verbal assumption is not a replacement for a clear contract.
27. Explain What Support You Expect After Launch
Software usually needs attention after release.
Therefore, ask what happens once the website or app goes live.
Will the development company fix bugs discovered after launch?
How long is the initial support period?
Does maintenance cost extra?
Who handles server problems?
Who updates the application when Android or iOS changes?
How are new features estimated?
Understanding these details before development begins can prevent disagreements later.
It also helps you plan the ongoing cost of maintaining your product.
What You Do NOT Need to Decide Yourself
Many business owners believe they need to prepare every technical decision before contacting developers.
Usually, that is unnecessary.
For example, you may not need to decide the programming language, database technology, backend framework, server architecture, state-management solution, or exact cloud configuration.
These choices should follow the business and technical requirements.
Your responsibility is to explain what the product needs to achieve.
The development team should then explain the technical approach in understandable terms and why it fits the project.
Of course, if your company already has technical standards or an existing technology stack, tell the developer.
Otherwise, focus on requirements rather than choosing technologies based only on trends.
A Simple Project Brief Example
Suppose you own a small chain of fitness studios and want a mobile application.
A useful project brief could say:
“We operate three fitness studios. Currently, customers call reception to book classes. We want an Android and iPhone app where customers can create an account, see classes at each location, check available spaces, book or cancel a class, and receive reminders.
Staff should have a web dashboard where they can create classes, set capacity, view bookings, and mark attendance.
Online payment is not required in the first version because customers already have memberships. However, we may add membership purchases later.
We already have a logo and brand colors. We would like the first version ready before our new studio opens in approximately four months.”
This brief does not contain technical architecture.
However, it gives a developer enough information to begin asking the right questions and planning the project.
What Happens After You Provide This Information?
Once the developer understands your requirements, they can start turning the idea into a structured project.
They may ask follow-up questions to remove unclear requirements.
Next, the team can define the project scope, user roles, important features, user journeys, integrations, and technical requirements.
Designers can then begin wireframes or UI/UX designs.
Meanwhile, developers can plan the technical architecture and identify potential risks.
After the scope becomes clear, the company can usually provide a more reliable estimate for development time and cost.
This is why detailed requirements are valuable.
The better the development team understands the project, the easier it becomes to estimate and build it realistically.
Common Mistakes to Avoid Before Development Starts
One common mistake is giving developers only a feature name without explaining how it should work.
For example, writing “payment system” does not explain what customers purchase, when they pay, whether refunds are available, or whether subscriptions are required.
Another mistake is assuming developers already understand your industry.
Even an experienced development team may not know the specific processes your business follows.
Businesses should also avoid changing the core idea repeatedly without discussing how those changes affect scope.
In addition, do not hide important constraints such as fixed deadlines, existing software integrations, or limited budgets until development has already started.
Clear information at the beginning makes it easier for both sides to plan realistically.
Quick Checklist Before Sending Your Project to a Developer
Before development begins, make sure the developer understands:
- Your business and what it does.
- The problem you want to solve.
- What type of product you need.
- Who will use it.
- The main user roles.
- Essential features.
- Features that can wait until later.
- Important user journeys.
- Business rules.
- Required platforms.
- Design references and branding.
- Existing content and assets.
- Third-party integrations.
- Existing software or databases.
- Login requirements.
- Payment requirements.
- Notifications.
- Admin-panel requirements.
- Reports and analytics.
- Security or privacy considerations.
- Your approximate budget.
- Your expected timeline.
- Your main business goal.
- Who approves decisions.
- Preferred communication method.
- Ownership and final deliverables.
- Post-launch support expectations.
You do not need every answer to be final.
However, providing as much of this information as possible gives developers a much stronger starting point.
Frequently Asked Questions
Do I need a complete technical document before hiring a developer?
No. You can begin with a clear explanation of your business, users, problems, features, budget, and timeline. The development team can help turn this information into more detailed requirements.
Should I tell a developer my budget?
Providing a realistic budget range can help the developer recommend a suitable scope and technical approach. It can also help identify which features should be included in the first version.
Do I need to choose the technology myself?
Usually, no. Explain your business requirements and any existing technical constraints. The development team can then recommend appropriate technologies.
What if I do not know all the features yet?
That is normal. Start with the problem you want to solve and the actions users must be able to complete. Additional requirements can be identified during the planning process.
Should I provide examples of other apps?
Yes. Examples can help developers and designers understand your preferences. However, explain which specific parts you like rather than asking them to copy another product.
Should I give developers passwords for my existing accounts?
Developers may need access to certain services, but credentials should be shared securely. Where possible, create appropriate team accounts or restricted permissions rather than sharing your primary passwords.
Should I prepare all website or app content before development starts?
Not necessarily. However, the team should know who is responsible for text, images, product data, videos, and other content. Missing content can delay later stages of the project.
What is the most important information to provide?
The most important information is the problem you are solving, who will use the product, what users need to do, which features are essential, and any important budget or timeline constraints.
Conclusion
You do not need to be a technical expert before starting a software project.
However, you should be able to explain your business clearly.
Tell the developer what problem you want to solve, who will use the product, what users should be able to do, and which features matter most.
In addition, provide information about your branding, existing systems, integrations, payments, admin requirements, budget, timeline, and future plans when they are relevant.
The developer can then turn these business requirements into designs, technical architecture, and a realistic development plan.
Most importantly, do not worry about having every technical answer before the first meeting.
A successful project usually starts with a clear business problem and good communication—not a list of programming languages.
