To start selling online, define one specific offer for one specific customer, then test whether people want it before investing in inventory or a paid storefront. Choose a sales channel that fits your product and workload, price in all the costs, publish a clear offer, and use early customer response to improve it. A store is a way to take orders—not a guarantee of demand.
How do I start selling online?
Begin with the offer, not the platform. Decide what you will sell, who is likely to buy it, and what problem, desire, or task it addresses. This applies whether you plan to sell a physical product, a service, or a digital item.

Define and test one offer
- Describe the offer in one sentence, including what the buyer receives and any important limits.
- Name the intended customer as concretely as possible. “People who need help” is too broad; a particular type of customer with a particular need is more useful.
- Look at competing offers: their prices, descriptions, delivery promises, and customer questions or complaints. Use that to identify what a buyer may value—not to assume you can win by being cheaper.
- Check for practical signs of demand before buying stock or paying for recurring software. Ask prospective customers, take appropriate preorders only if you can fulfill them, or publish a small test offer where permitted.
For physical goods, also determine whether you can source or make the item consistently and safely. For services and digital products, clarify the scope, delivery format, turnaround time, and what support is included.
What will it cost to make a sale?
Estimate the economics before committing to inventory, advertising, or a monthly platform plan. Calculate what remains from each sale after direct and selling costs; revenue alone does not show whether the offer is viable.

Build a per-sale estimate
- Production, materials, or the cost of buying the item you resell.
- Marketplace listing, transaction, payment-processing, or storefront charges.
- Packaging and postage for goods you ship, including any shipping amount you pay that is not covered by the buyer.
- Expected costs of returns, replacements, refunds, or failed deliveries.
- Promotion and customer-acquisition costs, plus recurring expenses allocated across expected sales.
- Your time, especially for made-to-order goods and services.
For example, if a buyer pays $40 for a shipped item, that $40 is not your take-home amount: subtract the item’s production or purchase cost, platform and payment fees, packaging, postage you cover, and a realistic allowance for returns and promotion. Set a price that accounts for those costs and still makes the work worthwhile. Check the actual fee schedule for your location and channel before setting the final price.
Understand the channel-specific fees
On Etsy’s US seller page, the listed fee is $0.20 to publish a listing; it lasts four months or until the item sells. Etsy also lists a 6.5% transaction fee on the sale price, including seller-set shipping, and US Etsy Payments processing of 3% + $0.25. These are US figures, not universal rates; processing fees vary by seller location, and fees can change. Confirm current charges on Etsy’s seller page before pricing.

Amazon’s seller guide lists its Professional selling plan at $39.99 per month, plus category-dependent referral fees and possible optional-service costs. Treat that as the plan price reported by Amazon’s current guide, not the total cost of selling. Confirm the current plan and charges at Amazon’s selling guide.
Which online sales channel should you choose?
A marketplace, an owned storefront, or a combination can work. The right choice depends on whether you need existing shopper discovery, how much control you want, and whether you can manage the work of bringing customers in. Amazon says sellers can use multiple channels, including its store, their own website, and social media; multiple channels are an option, not a requirement for a first sale.

| Marketplace, such as Amazon | Can put an offer in front of shoppers already using the marketplace, but visibility and sales are not guaranteed. | Marketplace charges apply. Amazon’s Professional plan is listed at $39.99 per month, plus category-dependent referral fees and possible optional-service costs; check the current guide. | Follow the marketplace’s listing, product, fulfillment, and customer-service rules. Amazon offers seller-fulfilled shipping and Fulfillment by Amazon, with suitability and costs depending on the product, order volume, and business goals. |
| Marketplace, such as Etsy | Can reach people browsing Etsy, provided the offer fits the platform’s rules. | US listed fees include $0.20 per listing, a 6.5% transaction fee, and US payment processing of 3% + $0.25; location affects fees. You have less control over the marketplace environment than over your own site. | Etsy requires items to be made, designed, handpicked, or sourced by the seller under its Creativity Standards. Shop opening also depends on Etsy Payments availability in the seller’s location. |
| Owned storefront | You generally have to attract visitors yourself through promotion, referrals, search, or other channels. | Offers more control over the storefront and customer experience, but may involve a recurring platform plan and payment-processing charges. Compare the current terms before choosing. | You set up and maintain the store, product pages, policies, and customer acquisition. A hosted ecommerce platform is one way to create a storefront, but software does not supply demand by itself. |
| Combination | Uses more than one route to reach potential customers. | May combine marketplace charges with storefront costs, while offering more control on the owned channel. | Requires maintaining accurate stock, prices, policies, and customer service across channels. Start with a workload you can handle. |
Amazon reports that independent sellers account for more than 60% of sales in its store, and that US independent sellers averaged more than $375,000 in annual sales in Amazon’s store in 2025. These are Amazon-reported figures about its marketplace, not typical beginner results or an income forecast. Platform-reported averages do not establish what a new seller is likely to earn.
Check Etsy eligibility before building a shop
Etsy is not a general-purpose marketplace for every product. Its rules require items to be made, designed, handpicked, or sourced by the seller under its Creativity Standards. Etsy also says a shop can be opened only in a country where Etsy Payments is available. Review the current Etsy shop-opening requirements and payment availability before relying on that channel.
Set up the offer so buyers know what they are getting
A buyer should be able to understand the offer, price, delivery, and next step without guessing. Configure the basics before publishing rather than leaving important terms to a later message.
For every offer
- Write a specific title and description that explain what is included, who it is for, and any relevant limitations.
- Use accurate images or examples. Show the actual item or clearly represent the result a service or digital product provides.
- Set a price and explain any additional charges before checkout.
- Provide a reliable way for customers to contact you and decide how quickly you can respond.
- State what happens if an order is delayed, cancelled, refunded, or otherwise cannot be completed, consistent with the platform’s rules and applicable law.
Additional setup for physical goods you pack and ship
- Decide who holds the stock and who packs and fulfills each order. You can ship yourself, use a fulfillment provider, or—in Amazon’s case—consider Fulfillment by Amazon, which stores and ships products under its service.
- Set a processing time you can meet, then give a realistic delivery estimate. Distinguish the time you need to prepare an order from the carrier’s transit time.
- Choose packaging and calculate shipping costs before publishing. State shipping charges, destinations, and return terms clearly.
- Plan how you will monitor stock and handle damaged, lost, or returned parcels.
A thermal shipping-label printer is optional, not a prerequisite. It may save time for some sellers shipping orders themselves, but it is unnecessary for services and digital goods, low order volume, or fulfillment providers that prepare labels.

Replace shipping details with clear delivery terms: what the customer receives, how and when it will be delivered, what information you need from them, and what revisions or support are included. Make sure the checkout and delivery process works before promoting the offer.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Check the rules that apply to your location and product
There is no single license, tax threshold, or registration rule that applies to every online seller. Requirements depend on where you operate, your business structure, what you sell, and where customers are located. Product-specific rules may also apply. Check official local government and tax-agency guidance, and seek qualified advice when you cannot determine how a rule applies. Platform eligibility does not replace your responsibility to follow applicable law.
Etsy says it does not require sellers to have a business license to sell on Etsy, while also making sellers responsible for laws that apply to their business. That platform policy is not a general legal exemption. See Etsy’s shop-opening help page for its own requirements, then check official rules for your jurisdiction.
Publish, promote, and learn from the first orders
Once the offer, price, delivery terms, and checkout are ready, publish it and make it easy for the intended customer to find. Start promotion with channels you can maintain: for example, relevant social posts, direct outreach where appropriate, referrals, or useful content aimed at the customer’s actual questions. Avoid spending heavily on advertising before you know whether the offer and its economics work.
Track what happens
- Visits: Are potential customers reaching the listing or storefront?
- Purchases: Do visitors buy? If not, inspect the offer, price, trust signals, and clarity of the page before simply increasing promotion.
- Questions: Repeated questions can reveal missing details in the description or process.
- Costs: Compare actual fees, fulfillment, returns, and promotion costs with your estimate.
- Returns and complaints: Look for patterns that may point to a mismatch between the promise and the product or delivery experience.
Use those observations to make one meaningful improvement at a time—such as clarifying a specification, revising a photo, adjusting a price, or changing a delivery promise—then watch whether the results improve. A first sale is useful evidence about one customer and one transaction; it is not proof that demand or profitability will continue.
