How to sell online: start an online store for your business

To sell online, you need a place to list products, a checkout that takes payment, and a way to get orders to customers. An e-commerce platform runs the store and orders, and a payment processor moves the money to your bank. You also need a plan for shipping, stock and returns, which the store software alone may not cover.

How to sell online

How to sell online, step by step

Decide what you will sell, where it ships and how you will handle returns.
Choose whether to run your own store, sell through marketplaces or social channels, or both.
Set up the store, product listings, photos and shipping rates.
Connect a payment processor and test a full order from checkout to your bank.
Check what sales tax and consumer rules apply where you sell, or ask your accountant.
Plan how you will pick, pack and ship, and how stock is updated after each sale.

This job usually also needs shipping & fulfillment. We don’t track that category yet, so we have no verified prices to show for it. We would rather say so than guess. The guidance on this page still covers what to look for.

What to look for

Editorial assessment

Transaction and payment fees Your cost per sale includes the platform plan plus payment processing fees. Compare them together, since low plan prices can come with higher per-sale fees.
Checkout and payment options Check which payment methods customers can use and whether you must use the platform's own processor. Missing a common method loses sales at checkout.
Shipping tools Look at how shipping rates are calculated and whether labels can be printed from orders. Shipping and fulfillment are often a separate service you add.
Out-of-stock handling Check that the store hides or flags items that have sold out, so customers cannot pay for something you cannot ship. Refunding those orders costs you reviews.
Sales channels If you also sell on marketplaces or social media, check that orders and stock from all channels land in one place.
Email capture The store should let you collect customer emails with consent and pass them to an email marketing tool, so you can bring buyers back.

Common mistakes to avoid

Comparing plan prices only The monthly plan is only part of the cost. Payment fees, apps, themes and shipping add up per order.
Launching without a test order Run a real order through checkout, payment, confirmation email and refund before you open. Problems found by customers cost sales.
Ignoring tax and shipping rules Where you must collect tax and what you can ship varies by location. Check before your first sale, not after.
No returns plan Online buyers cannot see or try a product before it arrives, so some will send it back. Set your returns policy and how returned items go back into stock before launch.

What to settle before you buy

Will we sell only on our own store, or also on marketplaces and social media?
Who packs and ships orders, and who handles returns and refunds?
How many products and variants do we have, and who keeps listings updated?
Do we also sell in person, and should online and in-store stock share one count?
Which accounting and email tools must the store connect to?

Frequently asked questions

How do I start an online store with no money?

Start small: a platform with a free or low-cost plan, a handful of products you already have, and a payment processor that charges per sale rather than monthly. Of the 2 e-commerce tools we track, WooCommerce lists a free plan or free tier (limits are in the table above); Shopify does not. Expect payment fees on every sale even when the plan itself is free.

How do I sell online without a website?

You can sell through marketplaces, social media shops or payment links sent to customers. These get you selling quickly, but the channel sets the rules and owns the customer relationship, so many sellers add their own store later.

What is the best e-commerce platform for a small business?

It depends on how many products you sell, which channels you use and how much setup you want to do yourself. The 2 e-commerce tools we track (Shopify and WooCommerce) are in the table above with verified entry prices and billing units.

What should I compare when looking at Shopify alternatives?

Compare total cost per order, not just the plan: plan price, payment fees and any paid apps you need. Also check how products, customers and orders can be moved over, since switching platforms later is real work.

How we built this page

We start from the job, not the product. The phrasings people search for this job (for example “how to sell online”) come from our research into how small and mid-size teams describe it. Which software categories the job takes is our editorial judgment. Every tool, entry price, billing unit and date comes from HelpCompare’s open dataset, recorded from each vendor’s own pricing page; nothing is estimated, and where a vendor publishes no price we say so. We take no affiliate commissions and publish no scores of our own. See our methodology or download the data from Open Data.
