Introduction

In 2025, the eCommerce is bouncing back even stronger. Customers now make decision based on the internet. Whether you are selling hadcraft goods, digital products or a new brand, having an online presence is crucial for the growth. In this blog, we’ll walk you through how to build an easy online store with Momen.

What Makes Momen a Better Choice

Popular platforms like Shopify, Wix, and WooCommerce make it easy to start but come with serious downsides:

• High transaction fees: Shopify’s basic plan costs $29/month, but if you make $5,000 in sales from 100 customers, you’ll end up paying at least $204/month in platform fees and transaction charges.
• Limited customization: Many e-commerce builders lock you into pre-set themes and functionalities. You’ll need plugins or developers for custom features.
• Scaling Constraints: As your business grows, you may need more features — many of which come as expensive add-ons or higher-tier plans. If you build with Momen, you own your store, your data, and your business logic with no code — no unnecessary costs or platform restrictions. You can keep 100% of your revenue. Owning full control of your design and logic. And Momen’s built-in backend make sure it’s scalable from day 1.

Core Features of Your Online Store

Core features

In this online store we build, you can get the following core functions:

• Product management: Add, edit, and organize products dynamically. Shopping cart & checkout: Let customers add/remove items and complete purchases with Stripe integration.
• User account system: Allow users to sign up, log in, and save their order history.
• Payment integration: Process payments directly via Stripe without needing extra coding.

How We’ll Build It with Momen

The process of building this online store will be divided into data, UI and payment logic.

Setting Up Data Model

The foundation of any app is its data model. For our store, we need four key tables:

• Account Table: Stores user information.
• Product Table: Holds product details like name, price, description, and images.
• Shopping Cart Table: Tracks selected items, quantities, and prices.
• Order Table: Stores order details and payment status.

Setting Up Data Relationships

• Products → Shopping Cart (1:N): A product can be in multiple carts.
• Accounts → Orders (1:N): A user can place multiple orders.
• Accounts → Shopping Cart (1:N): A user can have multiple cart records.
• Orders → Shopping Cart (1:N): A single order can include multiple cart items. Once the data model is in place, we can add product data in the database. Then we can move to UI design.

UI & Data Binding

Navigation & Login Page

The login page consists of a navigation bar and a login/signup window.

• Navigation Bar: A fixed bar containing the store name, cart icon, and login/logout buttons.
• Login/Signup Window: Uses a conditional view to toggle between login and registration forms.
• Data Binding: Inputs are bound to the Account Table to validate user credentials. Once logged in, users are redirected to the product listing page.

Product Listing Page

• Displaying Products: Uses a dynamic list bound to the Product Table.
• Product Components: Each item container includes an image, name, description, price, and an “Add to Cart” button.
• Conditional Button Logic: If a product is already in the cart, the button changes to indicate it’s been added.
• Action Handling: Clicking “Add to Cart” updates the Shopping Cart Table and redirects users to the cart page.

Shopping Cart Page

• Cart Items: Displays products added to the cart with quantity controls.
• Quantity Adjustments: Clicking “+” increases quantity and updates total price; clicking “-” removes items if quantity reaches zero.
• Data Filtering: Ensures only the logged-in user’s cart data is displayed.

Payment Processing

Checkout Button & Stripe Integration

• Activating Stripe: Set up API keys and connect payments to the Order Table. Payment Workflow:
• User clicks Checkout.
• If the cart is empty, a warning appears.
• If items exist, an order is created and cart items are linked to it.
• Stripe processes payment. On success, the order status updates, and the cart clears.

Final Preview & Testing

With everything set up, you can click “Mirror” to test if the UI looks nice. And you can click “preview” to mock the real web environment to test the flow:

1. Sign up/login.
2. Browse and add products to the cart.
3. Adjust quantities.
4. Proceed to checkout and complete payment.
5. Verify the database updates accordingly.

Cost & Time Estimate

Time

For a non-technical, building such an online store takes about 2–3 hours. This is a demo-level project which doesn’t contain inventory tracking or order management. You can expand features incrementally, like product detail pages, order tracking or even AI customer service as your business grows.

Cost

If you want to integrate with payment, you only need to pay for Momen’s Pro plan starting from $85 per month, no transaction fee needed. If you run out of your computing resources, pay as you needed.
