Many people want to sell online but don’t know where to start. Should you sell on Shopee, Lazada, TikTok Shop, or build your own website? How much do you invest, and how do you attract customers? These questions keep many from ever starting.

How Do You Start Selling Online?

Selling online starts with four main steps: choose your products and sales channel, open a store and list products with good photos and descriptions, set up payment and shipping, then market to attract customers. Each step has different decisions to make.

For beginners, the most important part is choosing the right channel, because each platform has different strengths, costs, and customer bases. Read the detailed steps in the article how to open an online store in 5 steps.

Where Should You Sell, Marketplace or Your Own Website?

Main sales channels fall into two groups: Marketplaces like Shopee, Lazada, and TikTok Shop that come with ready traffic and systems, and building your own store website that gives full control over your brand and customer data.

Most beginners should start on a Marketplace because buyers are already there without needing to build traffic yourself. Your own website suits growing brands that want to own customer data. Read the in-depth comparison in Marketplace vs your own website, and see how to compare platforms in which channel is best for selling online.

What Costs Are Involved in Selling Online?

The main costs of selling online aren’t just the product price but include platform fees, shipping, marketing, and packaging. In 2026, the transaction fee on major platforms is around 3 percent or more of the order value (FlowAccount, 2026).

Understanding all costs from the start helps you price correctly and avoid unknowingly losing money. Read the fee breakdown by platform in online selling fees 2026.

How Do You Market an Online Store to Grow Sales?

Opening a store doesn’t mean people will buy right away. Marketing is what truly drives sales. Main channels include running social ads, creating content, using creators, and doing SEO to rank in search.

For stores selling through TikTok Shop, ads that connect directly to the store often perform well. Read how to market across all channels in online store marketing.

The Back-End Systems Every Online Store Needs

What beginners often overlook is the back end: accepting payment, cash on delivery (COD), and shipping. These systems directly affect customer experience and operating costs.

As your store grows and sells across multiple platforms, systematizing order, stock, and shipping management becomes even more important. Read about payment and shipping in COD payment and logistics. If your business needs a complete online store setup, our team is happy to advise.

Selling online in 2026 starts with choosing products and a channel, opening a store, setting up back-end systems, then marketing. Most beginners should start on a Marketplace with ready traffic, then expand to their own website as the brand grows.

The key is choosing the right channel, understanding all costs, and marketing consistently. If you want to start on the right foot and set up a store ready to grow, planning with an experienced team can save time significantly.

Frequently Asked Questions

How much do I need to invest to sell online?

It depends on the channel and products. Starting on a Marketplace like Shopee or Lazada has almost no store-opening cost; you pay only fees when you sell, plus marketing. Building your own website adds website and system maintenance costs.

Which channel should beginners start with?

Start on a Marketplace like Shopee, Lazada, or TikTok Shop, because they come with ready traffic and systems, with no need to build a website or drive traffic yourself. They’re ideal for testing the market before expanding.

Do I need to register a company to sell online?

You can start selling as an individual without registering a company at first. But as sales grow to a certain level, you should consider tax and registration. Consult an accounting and tax professional as your business grows.

Why isn’t anyone buying after I opened my store?

Common causes are no marketing, unappealing products or descriptions, or uncompetitive pricing. Opening a store is just the start; you must market to drive people in and improve product pages to make them appealing.

Should I sell on one channel or multiple?

Beginners should get one channel stable first, then expand, because selling on multiple channels at once requires keeping orders and stock in sync, which is more complex. Once ready, expanding to multiple channels can boost sales significantly.
