The website and app development process in 2027, step by step

If you have never commissioned a website or an app before, the process can feel like a black box. You sign something, weeks pass, and then either a finished product appears or, more often, a stream of questions you weren’t expecting. It doesn’t have to work like that.

Here is how a professional build actually runs, stage by stage, with realistic timings and, most usefully, what you will be asked for at each step. We have written it around how we work at Razegreen, but you should expect something similar from any serious team.

The whole process on one screen

Stages overlap in practice. Design for the later screens often continues while development starts on the first ones.

1. Discovery and scoping

This is where the project is really won or lost. A good team will want to understand what the product must achieve for the business, who uses it, what they do today instead, and what success looks like in numbers. Expect workshops or calls, questions about competitors, and requests to see any existing systems the product must connect to.

What comes out: a written scope, a list of features split into “version one” and “later”, a technical approach and an estimate. If a company skips this and quotes from a two-line email, the quote is a guess.

2. Proposal and contract

You should receive an itemised proposal with milestones, payments linked to those milestones, the timeline, and what is excluded. The contract should cover ownership of code and accounts, confidentiality, warranty, how changes are handled and exit terms. Our guide on choosing a software company lists what to check.

3. UX: structure before looks

For a website, this means the sitemap and wireframes: which pages exist and what goes on each one, in plain grey boxes. For an app, it means user flows: every step from opening the app to finishing each task. It is far cheaper to move a box on a wireframe than to rebuild a finished screen, which is why this stage is worth your full attention.

4. UI design and a clickable prototype

Now the product gets its look: typography, colour, imagery, components, and how everything behaves on a phone and a laptop. For apps and complex websites, you should get a clickable prototype you can tap through like the real thing. Show it to a few customers. Their confusion now is worth more than anyone’s opinion later.

What you provide: your logo files, brand guidelines if you have them, and consolidated feedback. One voice giving feedback, not five, keeps this stage on schedule.

5. Development in sprints

Most professional teams now build in short cycles called sprints, typically two weeks long. At the end of each sprint you should see working software, not a status report. You click through what has been built, raise anything that doesn’t match your expectations, and agree what comes next.

Behind the scenes, good practice includes a staging environment separate from the live product, code review on every change, automated tests for the important paths and security checks. You don’t need to understand all of it, but you should ask whether it’s happening.

What you provide: content (this is the single most common cause of delay on website projects), access to any systems being integrated, and timely feedback after each sprint demo.

6. Testing

Testing covers features, forms, payments and integrations, on real phones as well as laptops, including a mid-range Android handset on a slow connection, which is how many Indian customers will actually use it. It should also cover speed against Google’s Core Web Vitals, accessibility basics and security. You should test too. Nobody knows your business rules better than you.

7. Launch

For a website, launch usually takes an hour or two of planned work: switching the domain, redirecting old URLs, submitting the sitemap to Google Search Console and checking analytics. If you are replacing an existing site, redirects are critical, as we explain in redesigning without losing rankings.

For an app, launch includes preparing store listings, screenshots and privacy disclosures, then waiting for Apple and Google to review the app. New personal Google Play accounts must also run a closed test with at least 12 testers for 14 days first, so register a business account or plan for it.

8. Warranty, then growth

The first few weeks after launch teach you more than the months before it. A warranty period, 30 days in our case, covers any bugs in what was agreed. After that, you choose whether to continue with a maintenance plan and a roadmap for the next version. For what that should cost, see our maintenance cost guide.

What actually causes delays

Almost never the code. In our experience the usual culprits are:

• Content that arrives late, or arrives as a 40-page document that needs rewriting for the web.
• Feedback that comes from several people who disagree with each other.
• New features added mid-sprint without adjusting the timeline.
• Waiting for access to a third-party system, a payment gateway account or app store credentials.

Sort out content, a single decision-maker and account access early, and most projects finish on time.

What’s different in 2027

Two things now belong in the process from the first week rather than the last. The first is data protection: with India’s DPDP Rules fully in force from May 2027, notices, consent, retention and breach handling have to be designed in, not added at launch. Our DPDP checklist covers what that means. The second is AI: if you want features like smart search or a support assistant, plan the data and integrations for them during discovery. Our guide to AI features and their costs helps decide which are worth it.

Our process at Razegreen

We run exactly these stages with fixed milestones, a demo every two weeks and a 30-day warranty after launch. If you want to see it applied to your project, have a look at our website and mobile app development pages or get in touch for a scoping call.
