Key takeaways
• Choose your ecommerce business model based on your target customers, whether selling directly to consumers (B2C), other businesses (B2B), or through government contracts (B2G), as each requires different strategies and approaches.
• Start with an established marketplace like Amazon or eBay to minimize upfront costs and technical complexity, then consider building your own website using platforms like Shopify or WooCommerce as your business grows.
• Implement integrated accounting software from day one to automatically track sales, expenses, and profitability, as digital transactions can quickly become complex to manage manually.
• Plan your fulfillment strategy early by deciding whether to handle inventory and shipping yourself or use dropshipping to reduce initial investment and operational overhead.
Ecommerce definition
Ecommerce (electronic commerce) means selling goods and services online, so your customers can buy from you without visiting a physical store.
The most common types include:
- Sell physical products through your website or marketplaces like Amazon or eBay
- Offer services and accept payments online using digital payment systems
- Sell digital products, such as downloadable content, software, or subscriptions
Types of ecommerce businesses
Ecommerce includes several business models. Each model depends on who is buying and selling. Knowing the differences helps you choose the right approach for your business.
B2C (Business-to-Consumer)
In this model, you sell products or services directly to individual customers. For example, you might run an online clothing store or offer a subscription box.
B2B (Business-to-Business)
In this model, you sell to other businesses. For example, you might offer software to other companies or supply parts to manufacturers.
C2C (Consumer-to-Consumer)
In this model, you sell directly to other individuals, often through a third-party platform. For example, you might use an online marketplace to sell used goods. If your sales exceed certain income thresholds, the platform must report your payments on Form 1099-K.
B2G (Business-to-Government)
In this model, you sell your products or services to government agencies. For example, some U.S. government agencies buy commercial products through online marketplaces to speed up procurement.
How ecommerce works
An ecommerce transaction usually follows a clear path, from a customer finding your store to receiving their order.
Here’s how a typical ecommerce transaction works:
- A customer finds your online store and browses your products
- They add items to their shopping cart
- At checkout, they enter payment and shipping details
- You process the payment and confirm the order
- You prepare and ship the product to the customer
Examples of successful ecommerce businesses
Ecommerce businesses sell physical goods, digital products, or services in many industries.
For example, you might run an online boutique, sell handmade crafts on a marketplace, or offer a subscription box. You could also sell online courses, software, or consulting services.
Advantages of ecommerce
Customer convenience: Shoppers can browse and buy 24/7 from anywhere, increasing sales opportunities
Faster payments: Digital transactions process immediately, improving your cash flow
Automated sales: Online stores operate continuously without staff, generating revenue around the clock
Lower overhead costs: No physical storefront means reduced rent, utilities, and staffing expenses
Global reach: Sell to customers worldwide without geographic limitations
Simplified bookkeeping: Digital transactions automatically integrate with accounting software for easier record management
What you need for an ecommerce business
To sell online, you need a few key tools and systems. Here’s what to set up:
Online storefront: A website or marketplace listing where customers can view products, prices, and descriptions
Shopping cart system: Technology that lets customers select multiple items and proceed to checkout
Payment processing: Secure systems like PayPal, Stripe, or Square to handle credit card and digital payments. For tax year 2024, these payment apps are required to send you a Form 1099-K if your gross payments for goods or services total over $5,000.
Fulfillment method: Shipping, delivery, or digital download systems to get products to customers
Business policies: Clear terms covering returns, refunds, privacy, and customer service procedures
Digital marketplaces often provide payment and delivery services for you. Keep in mind, they charge fees and may take longer to send your payments.
If you want to build your own shop, you can use an ecommerce platform to process orders and payments.

FAQs on ecommerce businesses
Here are some common questions and answers about starting an ecommerce business.
What is the most profitable ecommerce business?
There’s no single answer. Your profitability depends on your niche, marketing, and business model. You’ll do well if you find a product or service people want and offer it in a unique way.
How profitable is ecommerce compared to traditional retail?
Ecommerce can be very profitable because you have lower overhead costs – you don’t need a physical storefront. But the online market is competitive. Your profitability depends on your pricing, marketing, and how well you manage costs like shipping and transaction fees.
What's the difference between ecommerce and online marketplaces?
An ecommerce business usually means selling on your own website. An online marketplace, like Amazon or Etsy, lets many sellers list products. Marketplaces give you a bigger audience, but your own site gives you more control.
Do I need technical skills to start an ecommerce business?
No. Many platforms let you build an online store without coding. Drag-and-drop tools make it easy. Being willing to learn is more important than technical skills.
