How to Build an Online Store Website for Your Business: Steps, Platforms and Cost

Building an online store website starts with business decisions, not with picking a template: who your buyers are, how they pay and how the goods reach them. This guide covers the seven steps to building your own online store website, the platform options and the cost components, so you can decide whether to build it yourself or hire someone.

Your own online store or a marketplace shop?

A shop on Shopee, Tokopedia or TikTok Shop can be opened in a day and gets visitors from the platform straight away. In exchange, you follow the marketplace's rules, fees and layout, and your products appear right next to your competitors'.

An online store on your own website runs on your own domain. You control the look, the customer data, prices and promotions, and pay no per-transaction commission to a marketplace. The downside is that visitors don't arrive on their own: you have to bring them in through SEO, ads, social media or existing customers. Many businesses use both: a marketplace for new buyers, and their own website for repeat customers, corporate buyers and the full catalogue.

7 steps to build an online store website

1. Decide how you sell

Write down the products, how many products and variants there are, who buys them and where you ship. A store for individual shoppers needs a fast cart and checkout. A B2B business often does better with a catalogue and a request-a-quote button, because prices and order quantities are negotiated first.

2. Choose a domain name

Pick a domain that is short, easy to spell and matches your brand, such as a .com, .id or .co.id. Register it in your own company's name, not your developer's, so ownership is clear.

3. Choose how to build it

• A hosted platform such as Shopify. The fastest option with no servers to manage, but it carries a monthly subscription and you are limited to the features the platform and its apps provide.
• WordPress with WooCommerce. Flexible with a low upfront cost, but you have to look after the theme, plugins and security yourself.
• A custom website built with a framework such as Laravel. Suits a special sales flow, a catalogue of thousands of products, or a store that must connect to warehouse, accounting or ERP systems.

4. Prepare the product catalogue

Every product needs clear photos from several angles, a name that matches the words buyers search for, a description and specifications, a price, variants, stock, and weight and dimensions for calculating shipping. A tidy catalogue from the start speeds up the build and helps products get found on Google.

5. Set up payments and shipping

A payment gateway such as Midtrans or Xendit lets buyers pay by virtual account, e-wallet, QRIS or credit card, and updates the order status automatically once payment succeeds. For shipping, rates can be calculated automatically per courier from the address and weight, or you can use your own courier and offer free shipping, as some stores do.

6. Add the key pages and SEO

Besides the product pages, prepare an about page, a contact page, how-to-order, shipping and returns policies, and an FAQ. These pages build trust with buyers who don't know you yet. For SEO, make sure every category and product has its own title and description, light images, and that the website loads quickly on phones.

7. Test, launch and maintain

Before launch, place several test orders from a phone and a computer with every payment and shipping method. Once it is live, an online store needs upkeep: system and plugin updates, backups, and product and promotion changes. The full guide is in our article on what website maintenance is.

How much does an online store website cost?

The cost of an online store website is made up of several parts:

• The domain, renewed every year.
• Hosting or a platform subscription, paid monthly or yearly.
• Building the website: design, development, loading the first products and testing. This is the biggest part, and it depends on the number of products, the features and the integrations.
• Payment gateway fees per transaction, at the provider's rates.
• Maintenance once the website is live, by your own team or a provider.

Website costs in general are broken down in our article on website development cost. At PopOut, a custom online store website starts from Rp15,000,000 per project.

Build it yourself or hire someone?

Building it yourself on a hosted platform makes sense when you have few products, a standard checkout flow and someone on the team who can manage the look and the updates. Hiring a developer is the better choice when the store must match your brand, your sales flow differs from a typical shop (for example, special prices for B2B buyers), you have a large catalogue, or the website has to connect to other systems.
