Coming up with an idea.

First things first, it's important to develop your idea and prepare some marketing models properly. Here are a few examples of questions that you should consider:

Who is your target audience?
What is the mission and vision of your business?
What niche are you focusing on?
What are the risks your business may encounter?
What impact can political, economic, social, and technological factors may do to your business?

Make sure to answer these questions, and when you are ready to proceed with the next step, your feet will stay firmly on the ground, without wondering what if.

Finding products to sell.

Secondly, find the exact products you want to sell. Make sure they fall into your niche. It's better to polish and succeed in one category at first before embracing more of them.

The reason behind choosing only one category is that it's much easier to gain customers if you target only one niche. That way, you can work on polishing and presenting the product in the best possible way.

Presenting a lot of different products is more difficult as you will need to embrace a broader audience, spending a lot more time on marketing.

Finding a supplier.

After finding the products you wish to sell, it's important to find a supplier. The possibilities are very flexible as you can make the product yourself, find a manufacturer to make them, or even use a dropshipping method and sell items that a manufacturer sends out for you to your customers themselves.

Creating a website.

Once you are finished with the planning process, it's time to take action. An essential part is a website. If the website's performance is bad, it is most likely that a visitor will leave. A well-built website with great performance is the key to stability.

Now you might wonder what the process of creating a website is, so let me get that for you as it is quite easy and quick.

Getting a domain name.

First, you should think about a domain name. Try to make it short and catchy, so it's easy for people to remember your store name. Feel free to read my previous answer about how to create a domain name.

Getting a hosting plan.

You should start creating your website now. One of the popular ways is to get a hosting plan and choose a software that you want to build your website with.

To choose a hosting provider that suits your needs the best, you should consider a few of the important factors:

Performance. As loading speed is essential, especially for an e-store, a hosting provider must take initiation to improve website performance as much as possible.
Uptime. It's a crucial factor for an e-store, as every second your website is down can result in lost sales. Your website provider must offer great uptime.
Support. Your hosting provider should have a 24/7 Live Chat support that will always be there to help you. It's a great way to share any obstacles you experience as you can provide all of the examples through screenshots and links.
Price. It's always better to buy a product for a reasonable price and avoid overpaying. In fact, at NDMEAA technology, you can start your career with a hosting plan from as little as 79/month.
