Every B2B SaaS product with a compliance requirement (like banking, lending, payroll, or crypto) hits the same wall early on: before you can let a business use your platform, you need to verify who they are.

That means collecting a business type, pulling in registration documents, and showing the user where their verification stands, all without making onboarding feel like a customs form.

This article breaks down a working three step KYC (Know Your Customer) flow built with Shadcn UI: a stepper for progress, a radio group for account type, a file upload zone for documents, and an alert for verification status. You'll see the actual component code, not a simplified stand-in, along with the reasoning behind each decision.

You can try the finished flow at onboarding-kyc-flow.vercel.app. Click through it once before reading on, as it makes the code below easier to follow. And it also comes in dark and light mode.

Prerequisites

Before working through this flow, you should be comfortable with React function components and hooks, specifically

useState,

useRef, and

useEffect.

You should have:

• A Next.js project with the App Router and shadcn/ui already initialized, since this article doesn't cover that initial setup.

• A v0 account is optional. You can also use Bolt or Lovable, which support the same shadcn MCP prompt feature.

What You're Building

The flow has three steps:

• Account type: The user picks Startup, Enterprise, or Government. This decision drives the rest of the experience. It's shown back to the user as a confirmation line, and would typically decide which workspace defaults get applied.

• Document upload: The user drags in a business registration document, a tax return, or a company registry export, in PDF or CSV format.

• Verification status: The user sees a live status: checking in progress, then either verified or an issue that needs attention.

Project Structure

The project is a standard Next.js app with shadcn/ui already initialized. Here's the top-level layout:

components.jsonis the file the shadcn CLI reads to know where your components live and which style and primitives you're using.

Código Selecionar

components/holds the shared UI pieces (Alert, Badge, Button, Card, Progress, RadioGroup, Separator) that the flow is built from.

app/holds the page itself, shown in full below.
