Step 1: Discovery & Business Blueprinting

Planning allows you to understand a clear picture of your business and your audience. To evaluate these, you need to answer the following questions for yourself:

• Who is your ideal customer?

• What does success look like at 6, 12, and 24 months?

Deliverables typically include:

• Customer journey maps
• Feature prioritization
• Tech stack planning
• Scalability roadmap

This is where strategy meets reality. If you skip this process, then you're just guessing the whole business, and it takes lots of time and resources without a clear path.

Step 2: UX Architecture & Conversion Strategy

Beautiful design is not custom development, but you have to be strategic about what you are adding, where you are placing, and why this element matters in the website. Custom store development allows you to create user-friendly designs that your potential customers can easily explore and buy the intended products. In 2026, UX focuses on:
