What is Ecommerce

What is Ecommerce?

“What is ecommerce?” might be the first question that pops in your head when someone mentions it to you. As it’s growing in popularity, you might be hearing more people talking about the topic of ecommerce and online stores on a regular basis as a way to make money or to shop online. If you’re looking for an answer to the question ‘what is ecommerce’ we’ll answer all your burning questions on this topic and more. You’ll also learn how to start an ecommerce business, how to run an ecommerce website, and a lot more.

What is Ecommerce?

Ecommerce is a shortened version of the phrase “electronic commerce” which essentially describes any type of exchange of currency for goods or services online.

Ecommerce is an umbrella term that covers everything there is to do with buying or selling online, and can sometimes be otherwise written as “E Commerce,” “e-commerce,” or “eCommerce.” Any variation of the spelling is correct, and it all describes the same act of performing business via the internet.

Since the definition of ecommerce is so open-ended (it literally includes any type of buying or selling of goods or services online) there are so many different types of ecommerce businesses that exist. In this article, we dive deeper into the different types of ecommerce businesses that ecommerce business owners can run.

What is an ecommerce store?

An ecommerce store is a website that accepts payment for selling goods online. An example of an ecommerce store is Amazon, which allows you to buy products ranging from books to clothing using your credit card or other payment methods.

What is the difference between ecommerce and ebusiness?

The difference between ecommerce and ebusiness is that ecommerce is one type of ebusiness. Ecommerce focuses on online sales only, whereas ebusinesses generate revenue in multiple ways including ecommerce but also through offline transactions.

The Types of Ecommerce Business Models

The Types of Ecommerce Business Models

First things first, when you ask yourself, “What is ecommerce?” the best way to begin to describe different ecommerce businesses, and the different types of ecommerce businesses, is to break them down into the types of ecommerce business models that exist.

Ecommerce business models can be differentiated into three main categories:

  • What types of products are sold
  • Who the products are sold to
  • Where the products are sold on

Let’s look into these three identifiers further:

What Types of Products Are Sold?

Every ecommerce business can be differentiated by the types of products that it sells. There are four types of products that any ecommerce business can sell and they are:

  • Physical Products: clothing, dinnerware, picture frames, etc.
  • Digital Products: ebooks, music, online courses, etc.
  • Services: coaching, cleaning, tutoring, etc.
  • Affiliates: digital products, physical products, services, etc.

Every single ecommerce business online can fit into one or more of these categories, and this basically just tells you what type of products they sell to their customers.

Some ecommerce businesses sell physical products which means that the business has actual tangible products that they ship to their customers, and when their customers open the shipping package there will be a physical product they can touch, feel and see.

Conversely, digital products are a type of product that ecommerce businesses can sell online without shipping a product physically but digitally. Digital products can be instantly downloaded by customers so there’s a sense of immediacy with this type of product. It also helps to satisfy impulse shoppers since they get to dig into their new purchase right away rather than wait for their item to ship for a couple weeks.

Businesses can also provide digital or in-person services that their customers can purchase online. These services can include anything from design services or streaming services (both are digital services) to home improvement services or dog-walking services (which are in-person services). Any business that provides a service, rather than a physical or digital product, can be included in this category.

Finally, ecommerce businesses can also earn commissions via affiliate links which pay them a portion of the revenue for facilitating a sale. Ecommerce businesses that earn affiliate commissions could be blogs, influencer websites, or even websites like Canopy that curate products sold online for consumers. If you’re interested in creating your own affiliate ecommerce store, check out our Beginner’s Guide to Creating an Affiliate Ecommerce Store article.

Who the Products Are Sold To

Ecommerce businesses differ from each other based on who their target market is or who they sell to. A customer can be a person, a business, or a government. Let’s take a look at the three types of groups of that ecommerce businesses sell to:

These are the three main categories that ecommerce businesses sell their products or services to:

  • B2B: This stands for Business-to-Business. Ecommerce businesses that sell physical or digital products or services to other businesses fall under this category. For example, this could include manufacturers or suppliers that provide materials or products for other businesses. Shopify is a B2B business as it sells ecommerce subscription services to other businesses.
  • B2C: This stands for Business-to-Consumer. Ecommerce businesses that sell physical or digital products or services to consumers fall under this category. This includes retailers or ecommerce retailers that sell products to the end consumer. Amazon is a B2C business that sells various physical and digital products to consumers.
  • B2G: This stands for Business-to-Government. Ecommerce businesses that sell physical or digital products or services to government institutions or agencies fall under this category. For example, this could include businesses that create specialized software, office furniture, uniforms, etc. Mark 43 is B2G business that specializes in providing technology for police.

While most businesses generally sell their products to one of these categories, it’s entirely possible for ecommerce businesses to sell to more than one category of consumers. It’s important for ecommerce businesses to understand who exactly they sell their products to because it impacts important decisions such as their marketing, their branding, their shipping procedures, their markup, etc.

Where the Products Are Sold On

Finally, ecommerce businesses can also be differentiated based on the way they sell their products to their customers. These options are:

  • Branded Ecommerce Stores: These are ecommerce stores that are owned and operated by the founder(s) or creator(s) of the store, and they sell their own products on their own terms to their customer base. These types of stores are generally built on ecommerce platforms such as Shopify or BigCommerce.
  • Ecommerce Marketplaces: Ecommerce businesses can also sell through online marketplaces such as Amazon, eBay or Etsy. Each platform will have its own terms and conditions you’ll need to abide by to prevent being kicked off the platform. Certain products may be prohibited from different platforms. You might also need to keep a merchant review score to maintain your ability to sell on the platform. Also, some ecommerce marketplaces compete with their sellers, which might make it harder to sell your products on their website. Ultimately, you give up a bit of control when selling on ecommerce marketplaces.
  • Conversational Commerce: With social media being a major part of consumers’ daily routines, social media platforms are making it easy for consumers to shop through the posts on their newsfeed. Instagram Shop, Facebook Marketplace, Pinterest Shopping, and TikTok all have conversational commerce options that ecommerce brands can sell their products through.

The Different Ecommerce Platforms

Every ecommerce business needs an ecommerce store, which is essentially just a website where their customers can come to browse, learn about, and purchase their products.

Ecommerce businesses have different options when it comes to the ecommerce platforms they use to sell their products online, as we discussed in our Ecommerce Platforms: The Best Software, Reviews & Comparisons article. No matter whether a store wants to sell on marketplaces like Amazon, eBay, or Etsy they should also have an ecommerce store set up so they aren’t selling all their products through a middleman. Creating a self-branded store on an ecommerce platform is the only way to get full control over your ecommerce business, and it’s the best way to get full say on branding, marketing, customer experience, and revenue.

We discussed the Top 10 Ecommerce Platforms in great detail in this article, so for anyone interested in becoming an ecommerce business owner, that’s the most in-depth guide on ecommerce platforms we can recommend. For those who just want to get started on the best ecommerce platform in the industry, we recommend building on Shopify.

Where to Source Products for Your Ecommerce Business

Where to Source Products for Your Ecommerce Business

Sourcing products for your ecommerce business is going to be the next most important step when starting your own ecommerce business, and it depends largely on which ecommerce business model you choose to sell through.

There are 4 main ecommerce business models and each one dictates the way you’ll source your products. You can:

  • Make your products
  • Manufacture your products
  • Wholesale your products
  • Dropship your products

Make Your Products

If you choose to make your products, you’ll be in charge of sourcing all your materials so you can bring your products to life. The main challenge with making products for your ecommerce store is the time it takes to make your products, the cost, and difficulty incurred with sourcing materials to make your products, and how difficult it may be to scale your business should demand for your products increase. Another challenge with making your own products is that there’s no proof of concept that it’ll sell well. However, if the hard work pays off, you’ll be the exclusive owner of that product giving your ecommerce business a competitive advantage.

Manufacture Your Products

If you choose to get your products manufactured, you’ll need to source a manufacturer that can make your products. To do this, you could consult online directories such as our Manufacturer Directory to find a curated list of reputable manufacturers capable of making a range of different products, you could use a third-party manufacturer sourcing service such as Sourcify to help you find the perfect supplier for your products (the founder of Sourcify wrote two articles for our blog, check them out here: How to Source Products from Chinese Manufacturers and The Untold Secrets to Cutting Manufacturing Costs & Lead Times) and you could also find a manufacturer via an online manufacturer marketplace such as Alibaba or Maker’s Row. If you’re interested in sourcing your products from Alibaba, we highly recommend checking out our Guide to Sourcing Products from Alibaba so you can source your products as safely and securely as possible.

The main advantage of working with manufacturers to create your products is that you can custom-build products, you can get your products created exactly how you want them and you can keep your costs to a minimum. The biggest disadvantage of working with a manufacturer, however, is that you’ll very likely have to meet the minimum order quantities of your manufacturer which can be a major upfront cost.

Wholesale Your Products

When sourcing your products from wholesalers, you’ll be able to purchase your products in bulk without having to manufacture them yourself. Check out online wholesale directories (like our Wholesale Suppliers Directory!) to find wholesalers that sell products you’re interested in selling on your online store, or you could even source products in wholesale via AliExpress or these AliExpress Alternatives. You can also check out Handshake, a wholesale platform created by Shopify.

Dropship Your Products

If meeting upfront minimum order quantities sounds daunting or you just want the flexibility of not having to store inventory or ship products, then dropshipping may be the ideal business model for you. To source your products from dropshippers, your best bet is to check out an online dropshipping directory or even a roundup of the best Dropshipping Apps to Acquire Inventory for Your Business that integrates directly with Shopify stores, should you choose to start one. One of the advantages of dropshipping businesses is that you can sell best-selling items, quickly and at their peak. The downside is that other businesses might be selling the exact same product as you making it a more competitive space.

How Much Does It Cost to Start An Ecommerce Business?

Ecommerce businesses can be built on any budget. As we discussed in the “What is Ecommerce?” section of this article, ecommerce businesses are so vast and varied, they’re nearly impossible to define by any other identifiers rather than simply, “ecommerce.”

Since each ecommerce business is solely up to the entrepreneur(s) starting it, ecommerce businesses can truly be built on any budget. If your an entrepreneur building your first-ever ecommerce business and you only have a small budget to work with, start a dropshipping business, and pay attention to money-saving resources such as blogs dedicated to helping ecommerce businesses save money such as Bootstrapping Ecommerce, and keep your eye out for discounts on services to help you build, launch and grow your business such as our own Exclusive Offers page or AppSumo.

In any other case, your budget is entirely dependent on what you have to work with and how you want to allocate your finances. Work with an accountant or a bookkeeping team like Bench to keep your finances in check and use handy resources such as a Business Loan Calculator or a Profit Margin Calculator and even our PayPal Fee Calculator & Stripe Fee Calculator to make sure you’re keeping an eye on your budget in the places that matter most.

How to Buy & Sell Ecommerce Businesses

If you’re not completely interested in starting your own ecommerce business from scratch, it is possible to purchase ecommerce businesses that ecommerce entrepreneurs have already put time, effort, and money into growing to where they are today.

The best place to look for ecommerce businesses to buy online is Shopify’s Exchange Marketplace. Exchange Marketplace is a marketplace where Shopify store owners can go to list their businesses for sale or to purchase existing Shopify businesses, and the businesses available there are listed at a variety of prices depending on their traffic, customer base, revenue, etc.

If you’re interested in starting an ecommerce business and the idea of not having to completely start it from scratch is appealing to you, then check out Exchange Marketplace and see what’s on the market!

No matter when you’re starting your ecommerce business, though, it’s imperative to have an exit strategy sorted out so that if and when the time comes to sell your business or shut it down, you and any of your potential partners or investors know what the procedure is. Having an exit strategy in place can also help you make better decisions for your business throughout the years of its existence and it can help make investors keener to jump on board with your business. Learn more about crafting an exit strategy in our How to Sell a Business: Why Ecommerce Entrepreneurs Need to Have an Exit Strategy article.

How to Grow Your Ecommerce Business

How to Grow Your Ecommerce Business

Once you’ve gotten past the “What is ecommerce?” stage and you move onto building your ecommerce business, the final step and the step that’s going to take up the majority of your time as your business ages and scales, is how to grow your ecommerce business.

There are many ways to grow an ecommerce business but two of the main ways are through traffic and conversions. The more traffic you get coming to your ecommerce store the more conversions you’re likely to make which means more revenue and thus, more profit.

Traffic + Conversions = Revenue & Profit!

There are an endless amount of ways you can increase your store’s traffic, which we discuss some of in our How to Increase Website Traffic article, but one of the most successful ways is to treat your customers like people, not just numbers. If you focus too much on the numbers and how much revenue you’re making, you can lose sight of the most important aspect of your ecommerce business that makes everything worthwhile, and that’s your customers.

Obviously getting traffic to your store quickly helps keep you afloat when you’re new and just finding your footing and for that, we recommend checking out an article like our How to Get Your First 100 Sales article, but beyond that, take into serious consideration how you can add value to your customer’s lives so they’re more likely to purchase from your site again and spread the word about your company with their peers and social following.

To quickly bring traffic to your ecommerce store and generate buzz about your products or your store launch is to partner with influencers on platforms like TikTok. Partnering with the right influencer will allow your products to be positioned in an exciting way that helps generate tons of sales. You can also run paid ads on any social platform. Video ads tend to convert better as they have a loopable replay value that keeps people hooked.

Finally, if you’re looking for more in-depth ways to grow your traffic and conversions, we’ve created a 52 Week Marketing Plan to guide you through the process of growing your new business step by step. We created this guide because we noticed that growing a new business was such a daunting prospect for so many new merchants and we constantly receive questions from entrepreneurs asking us for our advice and recommendations. So, we put everything we know into one guide with the intention of helping as many new entrepreneurs as possible.

Once you start bringing more traffic to your ecommerce store then your conversion rate should grow organically from there but if you want to try out some other methods to get more visitors purchasing your products, check out our guide to Conversion Rate Optimization and this article on Conversion Rate Optimization for 1st Year Stores.
