1. E-Commerce

E-commerce means buying and selling goods or services online. Think of it as your shop being open 24/7, but instead of foot traffic, customers browse from their phones, laptops, or tablets.

From coffee roasters delivering nationwide to beauty brands selling via Instagram, e-commerce makes small business growth possible anywhere in South Africa.

2. Online store

Your online store is your digital shopfront, the main place customers visit to browse, learn about, and buy your products or services.

This could be a full ecommerce website, a simple online store builder, a marketplace profile or even a Facebook Shop. The benefit is that customers can browse your products outside normal trading hours, without you needing a physical shopfront. Just make sure your store offers a great customer experience with quality photos, clear pricing and easy navigation.

For small businesses that need a simpler starting point, a store builder with secure payments built in can make setup easier.

3. Shopping cart

A shopping cart is a virtual basket where customers keep items before buying. Just like in a physical store, it’s where they decide what stays and what goes.

A smooth shopping cart experience with clear delivery costs and multiple payment options can reduce abandoned orders and help you sell more.

4. Checkout

The checkout is where the customer confirms their order, enters their delivery details, and makes payment.

A fast, easy checkout helps improve sales and builds trust. If it’s clunky or confusing, people may leave before paying. A good checkout should feel secure, load quickly and give customers payment options they already trust.

5. Payment gateway

A payment gateway is the secure technology that processes online payments for your store. It connects your ecommerce platform to the customer’s bank so money can move safely. For example, a payment gateway can help you accept common online payment methods securely, while protecting both your business and your customers.

6. Merchant account

A merchant account is a special bank account that holds your online sales before transferring them to your main account.

Some payment providers manage this process for you, so you don’t always need to open a separate merchant account yourself.

7. Transaction fee

This is the small fee you pay each time a customer completes a transaction through your online store. It covers payment processing, security, and tech upkeep.

Knowing your transaction fees helps you set prices that protect your profit while keeping customers happy.

8. SSL Certificate

An SSL certificate keeps your customers’ personal and payment information safe during online purchases. It’s what makes that little padlock icon appear in a web browser.

Without it, customers may not trust your store. Many ecommerce platforms and online store builders include SSL security, so check that it’s active before you start taking orders.

9. Inventory management

Inventory management is how you track what products you have available, what’s running low, and when to restock.

iKhokha's catalogue feature lets you easily list and organise your products, but it’s not a stock tracking system. If you need full order tracking and stock level alerts, you might combine it with a dedicated tool.

10. Order fulfilment

Order fulfilment is how you get your product from your business to your customer. It could be through a courier, postal service, or local delivery.

A smooth fulfilment process improves customer satisfaction and increases the chances they’ll shop with you again.

11. Omnichannel

Omnichannel selling means reaching customers through more than one channel, such as your website, Instagram, WhatsApp, marketplaces and in-person sales.

It gives customers more ways to shop with you and creates a consistent experience across all channels.

12. Dropshipping

Dropshipping is when you list and sell products without keeping them in stock yourself. When someone orders, your supplier ships directly to the customer.

It’s low cost to start, but quality control is in the supplier’s hands, so choose partners you trust.

13. SEO (Search Engine Optimisation)

SEO is the process of making your online store easy to find in search engines like Google. It involves using the right keywords, having a mobile-friendly website and creating content that matches what customers are looking for.

14. Conversion rate

Your conversion rate shows how many visitors become paying customers. If 200 people visit and 10 buy something, your conversion rate is 5%.

Improving product descriptions, speeding up checkout and offering free delivery can help boost conversions.

15. Customer retention

Customer retention is about getting customers to buy from you again. Loyal customers spend more and are more likely to recommend you to others.

You can build loyalty with exclusive offers, great service and by keeping your brand top-of-mind through email or social media updates.

Understanding these terms makes it easier to build your online store with fewer surprises.

The right tools can help you set up your online store, accept payments and manage online orders more easily, but the most important first step is understanding what each part of the process does.
