Plenty of business owners want to start selling online, then stall at the first step because they cannot work out how to start: open a marketplace shop first, build a website first, or just sell through WhatsApp? That confusion is understandable. There are lots of options, and everyone gives different advice.
The good news is that starting to sell online is not as hard as it seems, as long as you do things in the right order. This article breaks down seven practical steps you can work through gradually, from choosing a product to measuring results, with the latest data and the beginner mistakes that most often stop a business halfway.
Why selling online is no longer just an optional extra
Shoppers' habits have moved faster than sellers have. The Indonesia Internet Profile Survey 2026 from APJII (the Indonesian Internet Service Providers Association) found that 30.1% of respondents shop online several times a month, and 6.5% do so several times a week. Your potential buyers are already used to buying through a screen. The only question is whether your business is there.
Ironically, most businesses have only scratched the surface. Statistics Indonesia (BPS) data from 2024, cited in the Ministry of Trade's 2025 PMSE (electronic commerce) Performance Report, shows that 94.76% of businesses selling through electronic systems still rely on messaging apps such as WhatsApp, while only 1.36% have a well-managed website. That is where the opportunity lies: competition on your 'own home' channel is still very thin.
Social media accounts for the largest share of transactions
BPS also found that 84.21% of national e-commerce transaction value comes from non-marketplace channels such as social media and instant messaging. So the idea that selling online always means selling on a big marketplace is wrong. Many small businesses actually grow from a combination of social media, WhatsApp and one simple, well-organised web page.
How to start selling online: 7 steps that make sense
Work through them in order. Do not jump to step six before step three is done, because that is the most common way budgets run out with nothing to show for it.
1. Settle on one core product first
Beginners often open a shop with fifty products at once, then struggle to keep up with stock and photos. Start with the one to three products you know best, that earn the most and that people ask about most often. Focusing makes learning to sell online much faster, and gives you room to improve quality before adding more lines.
2. Choose your first channel based on how your buyers shop
If your buyers spend their days on Instagram and TikTok, start there. If people find products like yours through Google search (repair services, building materials, office supplies), prioritise a website and Google Business Profile. There is no universal online sales channel; there is only the channel closest to your potential buyers' habits.
3. Build your 'own home' from the start
Marketplaces and social media are good for attracting attention, but their rules can change at any time and their commissions eat into your margin. Your own website gives you a permanent address, customer data and the freedom to decide how things look. For shops with lots of variants, our guide to building a WooCommerce online shop can be a safe, cost-effective starting point.
4. Tidy up your product photos and descriptions
Online, buyers cannot pick the product up. Bright photos on a clean background, and descriptions that answer real questions (size, material, delivery time, warranty), do the job a salesperson does in a physical shop. This is the most underrated part, even though it is the least expensive to fix, and the effect on your online sales shows quickly.
5. Make paying easy
A complicated payment process is a silent killer. A 2026 compilation of e-commerce statistics puts the average cart abandonment rate at 70.22%, and as high as 85.65% on mobile devices. 39% of shoppers cancel because of extra costs such as shipping that only appear at the end, and 24% back out because they are forced to create an account. Show shipping costs from the start, allow checkout without an account, and connect a payment gateway that supports QRIS (Indonesia's national QR payment standard) and virtual account transfers.
6. Bring in visitors deliberately
When a shop is quiet, the product is rarely the problem. Usually nobody knows the shop exists. There are two main routes: free but slow, through content and search engine optimisation, or paid but fast, through advertising. For location-based businesses, start with local SEO and Google Maps. If you need sales sooner, learn the basics of Google Ads for Indonesian businesses before you burn through your budget.
7. Measure, then fix one thing every week
Track just three numbers at the start: visitors, people who ask questions, and people who buy. Those three numbers tell you where the problem lies: not enough traffic, not convincing enough, or not easy enough to pay. This habit of measuring is what separates businesses that grow from those that stand still when they sell online.
A sensible starting budget
The next question is usually cost. As a rough guide, the earliest needs fall under just three headings: a domain name and hosting for a year, the cost of building or setting up a website, and a trial ad budget that can start small. Stock, packaging and promotional shipping costs come later, once you know which products are most in demand.
The key is to hold back from spending everything in the first month. Keep part of the budget to fix things you only discover once real buyers arrive, usually page speed, unclear shipping information or the product variants that turn out to sell best.
Beginner mistakes that stop online selling halfway
These four patterns are what most often stop a new business in its tracks.
- Spreading across every channel at once. Opening on five platforms at the same time sounds diligent, but the result is half-finished content everywhere. Master one channel until it is stable.
- Waiting too long for perfection. Delaying the launch for the 'right' logo and photos costs you months of real data from buyers.
- Replying to chats too slowly. Online shoppers tend to ask the same questions, and they move on if nobody replies. Preparing ready-made answers or a simple chatbot on your website closes this gap without hiring more staff.
- Advertising before the page is ready. Sending paid traffic to a slow, confusing page is the same as paying people to leave.
Start small, but keep going
No business gets busy in its first week. Aim for small, consistent improvements: product photos this week, the payment page next week, descriptions the week after. Within three months, those small improvements add up to a noticeable difference in revenue.
Conclusion: selling online is about order, not a big budget
Starting to sell online from scratch is actually simple: choose one product, meet buyers on their favourite channel, build your own home in the form of a website, tidy up your photos and payment process, then bring in visitors and measure the results. With only 1.36% of businesses running a well-managed website, there is still plenty of room to stand out for anyone willing to start today.
