Selling online is more than posting products on social media. A sustainable operation needs a product that solves a real need, an effective way to reach people, a clear process for closing orders and the ability to look after customers after the sale.
This article organises the fundamentals so you can build a model that can be measured and expanded, instead of depending on occasional random orders.
1. Research the market and the customer
Start with a specific customer group. Learn what problem they have, which solution they use now, what criteria they buy on and why they are not satisfied.
- Read competitors' product reviews to find unmet needs.
- Interview potential customers with open questions, not just "would you buy it?".
- Estimate the size, the spending level and the purchase frequency of the segment.
- Identify an advantage you can sustain: product, price, speed, service or experience.
2. Choose a product and validate demand
A suitable product needs clear enough demand, a reasonable margin and a stable supply. Before ordering in bulk, test with a landing page, pre-orders or a small batch.
- Count the full cost: goods, packaging, shipping, returns and payment fees.
- Check the origin, the distribution rights and any related legal requirements.
- Standardise the photos, specifications, usage instructions and warranty policy.
3. Price on real profit
The selling price should not just be cost plus an arbitrary percentage. You need to include customer acquisition cost, staff, platform fees, promotions and the refund rate. Track contribution profit per order so you know which campaign actually works.
4. Build the right sales channels
- Your own website: control over data, brand, SEO content and the payment flow.
- Marketplaces: existing traffic but high competition and dependence on platform policy.
- Social media: good for building a community, advising customers and creating demand through content.
- Email/Zalo/Telegram: caring for existing customers, transaction alerts and nurturing leads.
Note: You do not need every channel at once. Choose one channel that attracts customers and one place that reliably closes orders first.
5. What your website must include
- Product pages with benefits, specifications, real photos, price and a clear call to action.
- A short sign-up, ordering and payment flow that works on a phone.
- Transparent shipping, returns, privacy and contact information.
- HTTPS, backups, admin permissions and spam protection on forms.
- Tools to measure visits, order sources and conversion rate.
6. Standardise operations and customer care
- 01
Receive the order
Send confirmation automatically, verify payment and keep the customer clearly informed of the status.
- 02
Process and deliver
Use a packing checklist or issue the digital product to reduce mistakes and keep proof of delivery.
- 03
After-sales support
Define the response time, the contact channel and how returns or warranty requests are handled.
- 04
Measure regularly
Track revenue, profit, return rate, order value and the share of repeat customers.
