Online shopping is getting more and more popular. According to The Office for National Statistics (ONS) in January 2022, online sales made up 25% of all retail sales. Before the pandemic, in February 2020 it only made up 19.8% of all retail sales, showing steady growth.

All across Britain the self-starter movement is gaining momentum, more and more people are taking the leap and turning their passion project into income. 

In this blog, we offer some tips on how to start your own ecommerce side hustle. 

Check your employment contract 

Before you get stuck into starting your side hustle, you need to check your employment contract. 

While many businesses may not have a policy that prevents you from starting something on the side, it's always best to check. You want to make sure you don’t land into any hot water – or potentially lose your full-time job – if your contract says you aren’t allowed to start another business. 

It’s better to be safe than sorry. Even if there’s no clause in your contract about starting a business, it’s best to make sure your side hustle doesn’t affect your full-time job. 

Getting started 

Once that is sorted, it’s time to get started with making your side hustle a reality! 

First, you’ll need to plan and research your business idea. There are loads of different areas you can start a side hustle in – from teaching or coaching and selling homemade items to affiliate marketing. Speak to friends and family to bounce ideas around, or join a Facebook group with other side hustlers. You can find some ideas and inspiration here

Now comes the fun part – finding a name. This is a chance for you to get creative but you'll want to make sure the name you pick represents your brand in the right way. Make sure to do some research into what other businesses in your space are doing and are called so that you can set yourself apart. This is also a great time to make sure no one else has the same name as you. 

Once you’ve done that, you can get onto writing a business plan. This is a good chance for you to document your approach, how you’ll position it and understand your competitors more. You can find information on how to tackle your plan here

Online marketplaces are a good place to start and there are a few that could help you. did extensive research into the best ecommerce platforms for small businesses and found that comes out on top. The analysis shows that it’s a great all-rounder platform. Though there is a cost for ecommerce and business plans. Prices start at £13 a month for the basic plan and go up to £22 a month.

Finance and social media tools

When running your ecommerce store, there are some other tools you might need to help manage your finances, keep track of your projects and help to schedule and analyse your social media.
