However, an online commerce project requires one to first understand the main requirements for creating and maintaining a digital store. A wrongly made requirements list could result in a project with missing features or even not working at all.
What should I do to present an eCommerce website containing the right functional and non-functional eCommerce website requirements? Get the eCommerce checklist along with the straightforward tips here!.
Functional Requirements for an eCommerce Store
Functional online store requirements can be understood as the user’s view of what they can see and how the website will interact with them. Hence, these are the specifications for the different features of your store. For instance, you might want to implement a feature that would send an email to the customers confirming their order post-purchase. This feature is included in the development process according to the eCommerce functional requirements.
You will easily check off the eCommerce website requirements listed below if you are planning a new site, or if you wish to improve an existing one by making it richer with new functionalities.
Content Management System
The content management system (CMS) you select will be the major factor for your eCommerce possibilities and its flexibility. Furthermore, if you intend to develop an online store with WooCommerce, then you need to think of the hosting company and get the best theme and plugins that cater to your requirements.
Conversely, if you select Shopify, the door swings wide open to numerous ready-made tools that would make life easier for the sellers. The eCommerce store will be able to use the range of responsive templates from Shopify, giving it the highest level of adaptability. This enables the website to take on a nickname that is in line with the brand image. The two platforms also provide the option to create blogs, which can be a source of more traffic to the store and also have content management access for the admin of the website.
Product Catalog
Once you have selected a platform for your business, think about additional eCommerce functions that will be necessary for arranging your products. The establishment of product categories is to be made, and the website administrators should be given the right to add, remove, and modify products in the catalogue. Moreover, every product needs to have its own unique page with a brief and detailed description, pictures, properties, price, and stock.
Search and Filtering
A place on your site has to be designated for a search bar to look for a specific product using the keywords, name, and category. Also, to ease the search, allow filtering features to work on price, brand, colour, size, and other relevant factors. Moreover, a better customer experience is created by allowing sorting of products based on price, popularity, ratings, and more.
Shopping Cart
Online shopping carts must be created in such a way that shoppers can easily put items into the basket and check the product quantities, their prices, and the total cost. Customers ought to be allowed to make their shopping carts more specific by taking out or putting in items, and even by emptying the whole cart. One of the optional features for an online shopping site that helps ina good customer experience is the Save for Later option that lets customers keep things for further purchases.
Checkout Process
In order to obtain the highest conversion rate, you have to make your checkout process as easy as possible. A purchase form should be designed for its usability; absolutely nothing should be able to block or mislead the users in this journey. One of the best tips for an eCommerce site is to provide a guest checkout, which gives customers the option of buying without having to sign in.
Besides, you would need to cater to many different payment options, like credit and debit cards, PayPal, Google and Apple Pay, etc. With various shipping methods, including fast and free shipping, the customer has more power over their order. Do not forget to include a section for the shipping address. Give your customers a chance to check their order before they pay, and after the transaction is done, send them a confirmation either by email or SMS.
Order Management
The users are to have the option to monitor the progress of their orders at every stage: processing, shipping, and delivery. You are to give them the right to view their past orders and even place new orders based on those. Furthermore, the order management system will let users cancel their orders prior to shipping, and also request returns and exchanges.
Inventory Management
Your system ought to refresh product availability on its own according to stock levels, and when stocks drop, an administrator should be informed. Besides that, you will need an inventory control feature for multiple locations (like warehouses and retail stores).
Product Reviews and Ratings
Social proof gives customers the assurance they need to make their purchases. It appears in three ways: ratings, reviews, and testimonies. Ratings and reviews are obvious; they give the visitors of the site the possibility of understanding how other buyers think about the products and services before they decide to purchase.
The value of testimonials lies in the fact that they are not grounded on numbers or facts but rather an endorser client who might sound more genuine than the praises from regular people.
Put a review option on your product detail page and give buyers the chance to share their opinions about the purchase. The moderators in charge of your site should be able to oversee the reviews and take down any if necessary.
Technical & Legal Requirements
The regulations governing online store requirements serve as a shield to both clients and companies. They regulate the issues of privacy regarding personal data, security of financial transactions, and the moral practices of corporations.
Choose the Right Business Structure
Even though the law does not necessitate business registration, it is still a wise move to safeguard your enterprise. Talking to an attorney can help you decide which option is most suitable for your situation.
- Sole proprietorship. If you do not incorporate, your business will be treated as a sole proprietorship by default. It is a less formal option with fewer paperwork, but it does not provide personal responsibility protection.
- Limited liability company (LLC). Registering as an LLC gives you personal liability protection and tax flexibility.
- Corporation. Large businesses are often registered as companies. Corporations offer shareholder options and provide significant legal protection.
Sometimes you might need a business license to operate legally in certain situations. Mostly, this applies to certain types of businesses like alcohol and agriculture, which are under special regulations. If you are going to set up a reseller business, a certain license may be required from you as well.
Understand Tax Obligations
Tax laws for sales vary across states and some specific countries. They make it easier when you understand the laws properly so that you can tell the customer when and how you are really passing the taxes to them, and when the tax liability will be yours. Such knowledge of laws helps you in selling the products at a certain price and still making a profit on every sale.
Besides, keeping tabs on tax dates for businesses will also be necessary. Business taxes are different from personal taxes; for example, some states require companies to pay taxes every three months.
Consider Business Insurance
In case you have workers, it is likely that you will have to lay out money for workers’ compensation, unemployment, and disability insurance. All of these are meant to secure both the employees and the company in case of an accident, such as injury at work.
Insurance is not always a must in business, especially if there are no employees, but many times it is a wise decision. A large number of online retail sellers also prefer to take out insurance policies that are for both property damage and liability claims.
To understand more, property damage insurance covers warehouses, and any physical property, such as office spaces, stocked with the products that are used by the company and also includes retail business, if you have one. On the other hand, liability insurance policies pay for any possible legal fees related to any lawsuits which your company might encounter.
Store UX Checklist
Conceiving a Shopify store that is able to yield sales is first and foremost a matter of skeleton and usability, not ornamentation. The use of a responsive theme guarantees that your store is always functioning the same way, no matter what device is being used, which is very important because mobile gets a big share of the eCommerce traffic.
| Step | What to do | Why it matters | Impact on sales |
| Choose a responsive theme | Select a theme that adapts to all devices | Ensures consistent UX on mobile, tablet, and desktop | Higher engagement, lower bounce rates |
| Adjust colours, fonts, and layout | Optimise for mobile | Aligns store with brand identity | Builds recognition and trust |
| Create an engaging homepage | Simplify menus, compress images | Improves speed and usability on phones | Better mobile conversions |
| Add essential pages | About, Contact, FAQ, Shipping | Builds transparency and trust | Reduces hesitation before purchase |
| Use high-quality images | Professional product visuals | Enhances perceived product value | Increases conversion rates |
| Create engaging homepage | Clear messaging and structure | Guides first-time visitors | Stronger first impressions |
| Set clear navigation | Logical categories and menus | Helps users find products quickly | Faster path to checkout |
| Add breadcrumb navigation | Visible page trail | Improves usability and orientation | Lower drop-off rates |
| Add trust badges & reviews | SSL, payments, testimonials | Reduces perceived risk | Higher checkout completion |
| Create a blog section | Educational, product-related content | Supports SEO and authority | Long-term traffic and sales growth |
Store users are less likely to experience uncertainty and are more inclined to navigate the store confidently if the essential pages, intuitive navigation, breadcrumb trails, and visible trust badges are present. The store’s products are presented professionally through high-quality images and a lively homepage, and customer reviews add to the store’s trustworthiness.
