How to Build a Client Portal in Replit

Build a client portal in Replit with four components: a login system (using Replit Auth or custom authentication), a dashboard showing the client's specific project information, a documents section where you upload files they can download, and optionally a status tracker showing project milestones. Claude builds each component from a plain language description. Total build time for a basic portal: four to six hours.

Why Build a Client Portal

A client portal reduces the number of "where is my thing?" emails you receive. Instead of clients emailing you for status updates, invoice copies, or deliverable access, they log into the portal and find everything themselves. For service businesses that deliver documents, designs, or project outputs, a portal is one of the highest-ROI tools you can build.

The minimum viable portal: a login page, a dashboard with basic project info (name, status, next milestone), and a documents section where files are accessible by download link. This covers eighty percent of client needs and takes a weekend to build.

What to Describe to Claude

"Build a client portal with: Replit Auth login, a /dashboard route that shows the logged-in client's name and project status, a /documents route that shows a list of files with download links, and an admin route at /admin where I can add new clients, update their project status, and add document links. Use a SQLite database with a clients table (id, name, email, project_status, project_name) and a documents table (id, client_id, document_name, document_url, created_at)."

Adding Multiple Clients

The admin route is what makes this a real tool versus a demo. You need to be able to add new clients, update their project status as work progresses, and add document links when deliverables are ready. Ask Claude to build a simple admin interface at /admin with forms for each of these actions.

Frequently Asked Questions

How do I build a client portal in Replit?
Four components: a login system, a client dashboard showing their project information, a documents section with downloadable files, and an admin interface for managing clients and deliverables.
How do clients get their own login credentials?
With Replit Auth, clients use their Google or GitHub account to log in. With custom auth, you create an account for each client with a temporary password they change on first login. Ask Claude for whichever approach fits your workflow.
How do I add documents for clients to download?
Store document links in a database table linked to the client. The portal displays links to hosted files (Google Drive, Dropbox, or a Replit-hosted file). Ask Claude to build the admin interface for adding document links.
Can I send clients a notification when new documents are available?
Yes -- add an email notification to the document upload flow. When you add a document in the admin interface, the app sends an email to the client via your email service API.
How do I keep different clients' data separate?
Each client has a unique ID in the database. Every database query filters by client ID. Claude implements this automatically when building a multi-client portal.
