Introduction
A good app starts with a good brief. When the brief is vague, developers guess, proposals look very different from each other and the project drifts. This guide explains how to prepare for custom app development in India: what to write down, what to decide yourself and what to ask a developer so that you can compare proposals fairly.
TL;DR / Quick Answer
Before you contact developers, write a one-page brief that covers your goal, your users, the main things the app must do, the devices it must work on and how you will know it is working. A clear brief helps you get comparable proposals and avoid surprises later.
Why Custom Instead of Ready-Made
Ready-made tools are often the right place to start. Custom development makes sense when your process is different from what tools allow, when you need the app to connect with your own systems, or when the app itself is the product. Be honest about which case you are in. A good developer will tell you if a simpler option is enough.
What to Put in Your Brief
- Goal: what problem the app solves and for whom.
- Users: who will use it, and what each type of user needs to do.
- Main features: the few things the app must do on day one.
- Devices: Android, iPhone, web or a mix, and why.
- Connections: any payment, messaging, calendar or other systems the app must talk to.
- Success: what you will look at after launch to decide it is working.
Decide These Things Yourself
Some decisions are yours, not the developer's. These include who will make decisions on your side, how quickly you can give feedback and what matters most if you have to choose between speed and extra features. Write these down too. They affect the plan more than any technical choice.
Native, Hybrid or Web: Ask for a Plain Explanation
Developers may suggest different ways to build the app. Ask each of them to explain their choice in plain words and to say what it means for your users and for future changes. You do not need to understand every technical detail. You need to understand the trade-offs.
Comparing Proposals
When you receive proposals, line them up against your brief.
- Does each proposal cover the same features, or are some left out?
- Is the plan broken into clear stages with something to review at each stage?
- Does it say who owns the code, the designs and the accounts?
- Does it include testing and help after launch?
- Is the communication plan clear: who you talk to and how often?
A proposal that is much shorter or cheaper than others may simply cover less. Ask what is not included.
Questions to Ask a Developer
- Have you built something similar, and can I see it?
- How will you keep me updated during the work?
- How are changes handled once the work has started?
- What do you need from me and by when?
- What happens after launch if there is a problem?
Common Mistakes
- Starting without a written brief.
- Trying to include every idea in the first version.
- Choosing only on the lowest number without checking what is covered.
- Not agreeing who owns the code and accounts.
- Skipping testing with real users before launch.
Plan the First Version Small
If you are not sure what to include, start with a smaller first version and add features after launch. Our guide on moving from app idea to MVP explains how to do that.

Frequently Asked Questions
How detailed should my brief be?
One or two pages is enough to start. It should be clear about the goal, users and main features. Details can be worked out together.
Do I need a designer first?
Not necessarily. Many teams include design in the project. Ask what is included.
Should I build for Android and iPhone together?
It depends on your users. Ask which devices your customers actually use and start there.
What if my idea changes during the project?
Changes are normal. Agree on how they will be handled, and keep the first version small enough to adjust.
Conclusion
A clear brief saves time and money. Write down your goal, users and main features, decide what matters most, and ask each developer to explain their plan in plain words. Then compare proposals against your brief, not against each other's sales language.
