PageBitz – Multi-Tenant SaaS Landing Page Builder

A full-stack SaaS platform that enables entrepreneurs and businesses to create, customize, and publish high-converting landing pages while managing orders, customers, and leads from a centralized dashboard.

The Problem: Building a Product Page Is Only the Beginning

Launching a product online often requires several disconnected tools: a landing-page builder for the storefront, a separate system for collecting orders, spreadsheets or CRM software for managing customers, and additional services for payment and delivery.

For small businesses and entrepreneurs, managing all of these systems creates unnecessary complexity.

I wanted to build a single platform where a business could create a product landing page, publish it, collect customer orders, manage leads, and handle fulfillment from one dashboard.

The goal was to combine the simplicity of a landing-page builder with the core functionality needed to run a lightweight online-selling operation.

The Solution

I built PageBitz, a multi-tenant SaaS platform where users can create and publish customizable landing pages and manage the customer journey from the first visit through order fulfillment.

Users can:

• Build landing pages using reusable sections

• Customize themes and page layouts

• Preview changes while building

• Publish pages through dedicated routes

• Publish pages using wildcard subdomains

• Collect customer orders

• Manage customers and leads

• Track order status

• Manage email leads

• Integrate payment and courier services

Everything is managed through a centralized dashboard, removing the need to maintain separate tools for different parts of the selling process.

Platform Architecture

PageBitz is designed as a multi-tenant SaaS platform, meaning multiple businesses can use the same application while maintaining their own pages, customers, orders, and settings.

A simplified architecture looks like this:

The architecture separates platform-level administration from individual tenant operations while keeping the entire experience within one application.

Section-Based Page Builder

One of the core features of PageBitz is its section-based landing-page builder.

Instead of requiring users to understand HTML, CSS, or frontend development, the platform provides configurable sections that can be combined to create a complete product page.

Users can customize:

• Hero sections

• Product information

• Images

• Text and typography

• CTA buttons

• Feature sections

• Testimonials

• Pricing/content blocks

• Order forms

• Page themes

The builder is designed around reusable components and configuration-driven rendering, allowing the same underlying system to generate different landing pages for different businesses.

Live Preview & Publishing

A major part of the builder experience is the ability to see changes before publishing.

The platform separates the page-building experience from the published customer-facing page, allowing users to work on their pages without disrupting the live version.

Once a page is ready, it can be published through:

Route-based URLs

pagebitz.com/p/my-product

or through wildcard subdomains:

myproduct.pagebitz.com

This required handling hostname-based tenant identification and routing so that the platform can determine which business and page should be rendered for each request.

Multi-Tenant Architecture

Supporting multiple businesses on a single SaaS platform introduced an important architectural requirement: tenant isolation.

Each user's pages, customers, orders, and configuration must remain logically separated.

The application therefore associates platform data with the appropriate tenant and uses that context throughout the request lifecycle.

Conceptually:

Incoming Request
      ↓
Identify Host / User
      ↓
Resolve Tenant
      ↓
Load Tenant Configuration
      ↓
Fetch Tenant Data
      ↓
Render Response

This architecture allows PageBitz to operate as a shared SaaS platform while keeping individual businesses' data logically separated.

Order Management

PageBitz goes beyond being a landing-page builder by incorporating a complete order-management workflow.

When a customer submits an order through a published landing page, the platform captures the relevant customer and order information and makes it available through the business dashboard.

Businesses can then:

• View incoming orders

• Review customer information

• Update order status

• Track customer history

• Manage order fulfillment

• Coordinate courier delivery

This turns the landing page into an actual sales and order-collection system rather than simply a marketing page.

Mini CRM

I also built lightweight CRM functionality directly into the platform.

Instead of forcing businesses to export leads into another system, PageBitz maintains customer and lead information inside the dashboard.

Businesses can manage:

• Customer profiles

• Contact information

• Order history

• Leads

• Email information

• Customer activity

This creates a continuous workflow:

Landing Page
     ↓
Visitor
     ↓
Lead / Customer
     ↓
Order
     ↓
Fulfillment

Payment Integration

Because PageBitz targets businesses operating in Bangladesh, the platform was designed around locally relevant payment workflows.

The system supports manual payment collection through services such as:

• bKash

• Nagad

This allows businesses to configure payment workflows suitable for their target customers without requiring a traditional international card-payment setup.

Courier Integration

Order fulfillment is another important part of the platform.

PageBitz integrates with courier services such as:

• Pathao

• SteadFast

The goal is to reduce the amount of manual work required after an order is received.

Instead of copying customer information from one system into another, order information can flow from the landing page into the fulfillment workflow.

Super Admin Platform

PageBitz contains two distinct operational layers.

User Dashboard

Business users can manage:

• Landing pages

• Customers

• Orders

• Leads

• Account settings

• Subscriptions

Super Admin Panel

Platform administrators have broader control over the SaaS ecosystem, including:

• User management

• Subscription management

• Platform configuration

• Referral management

• Overall platform monitoring

This separation allows PageBitz to function as a real SaaS product rather than a single-user web application.

Key Engineering Challenges

1. Multi-Tenant Page Delivery

One of the major challenges was serving different landing pages depending on the requested route or subdomain.

A request such as:

store-a.pagebitz.com

and:

store-b.pagebitz.com

must resolve to different tenants and render completely different content while using the same underlying application.

This required careful handling of hostname resolution, tenant identification, page lookup, and rendering.

2. Dynamic Page Rendering

Because users can create different combinations of sections, the published page cannot rely on a fixed layout.

The system uses a configuration-driven approach where page structure and section settings determine what components are rendered.

Conceptually:

Page Configuration
       ↓
Section Definitions
       ↓
Component Resolver
       ↓
Dynamic Components
       ↓
Published Page

This makes the page system extensible because new section types can be introduced without redesigning the entire publishing architecture.

3. Keeping Builder and Published Content Separate

Another challenge was ensuring that users could edit their pages without unintentionally changing the live customer-facing version.

I designed the publishing workflow around the distinction between the editable page state and the published state, allowing changes to be prepared before being exposed to visitors.

The Result

PageBitz evolved from a simple landing-page builder into a broader commerce-focused SaaS platform.

It brings together:

Landing Pages + Lead Management + Orders + Customers + Payments + Courier Fulfillment

within a single platform.

From an engineering perspective, the project allowed me to work on considerably more complex problems than a conventional CRUD application, including:

• Multi-tenant SaaS architecture

• Dynamic page rendering

• Wildcard subdomain routing

• Configuration-driven UI

• Authentication and authorization

• Order management

• CRM-style data management

• Payment workflows

• Courier integrations

• Subscription management

• Referral systems

• User and platform administration

The project demonstrates my ability to take a product from concept and architecture through implementation and production, while solving both the user-facing and backend problems required to operate a real SaaS platform.
