How to start an online store: a step-by-step guide from first product to first 90 days

Starting an online store has never been more accessible. You do not need to rent servers, hire developers or sign long contracts to take your first order. What you still need is a clear plan: the right product, honest numbers, a store customers trust and a way for people to find it.

This guide walks through the process in order, from choosing what to sell to the first 90 days after launch. Resist the temptation to jump straight to designing your homepage.

Step 1: Choose and validate what you will sell

The product decides almost everything else: your margins, your shipping costs, your competitors and your marketing. Start with a short list of ideas, then test each one against reality.

Where product ideas come from

• A problem you understand: a hobby, a profession or a community you know well. You will write better product pages and spot gaps others miss.
• An existing offline business: a shop, workshop or wholesaler that wants to reach customers online.
• Your own brand: products you design or source and sell under your own name.

How to validate demand

Before you buy inventory, look for evidence that people want what you plan to sell:

1. Search demand: type your product and related phrases into Google and look at autocomplete suggestions and "People also ask" questions. Real searches mean real interest.
2. Competitors: who already sells it, at what price, and what do customers complain about in their reviews? Complaints are opportunities.
3. Marketplaces: browse the category on Amazon, eBay or Etsy to see how crowded it is and how products are presented.
4. Small test: pre-orders, a small first batch or a simple landing page with a waitlist tells you more than any survey.

Check the numbers

For every product, work out the unit economics: what it costs you, plus packaging, payment fees, shipping, a share of returns and marketing, against the price customers will realistically pay. If the margin only works when everything goes right, it will not work.

Step 2: Set up the business basics

Selling online is running a business, and some groundwork is needed before you take money from customers. In general terms, most new sellers need to think about:

• Business structure: whether you trade as a sole proprietor or set up a company. In the US this might be a sole proprietorship or an LLC; in the UK, sole trader or limited company.
• Registration and licenses: some locations or product categories require registration, permits or specific labeling.
• Taxes: income tax on profits, plus sales tax in the US or VAT in the UK and Europe depending on where you sell and how much.
• A separate bank account: keeps business and personal money apart and makes bookkeeping much easier.
• Bookkeeping: a simple system from day one to track sales, costs and invoices.
• Store policies: privacy policy, terms of service, shipping policy and returns policy.

Step 3: Pick your platform and domain

You have three broad options for the technical side:

• Hosted SaaS platform: you sign up, choose a design and start adding products. Hosting, security and updates are handled for you. This is the fastest path for most new stores.
• Open source software: free to download, but you manage hosting, updates and security yourself or pay someone to.
• Custom build: developed from scratch. Rarely the right choice for a first store because of cost and time.

For a first store, prioritize: a free or low-cost plan to start, no commission on sales, easy design tools, built-in SEO, the payment methods your customers use, and room to grow into marketplaces or a physical store later. Our guide on how to choose an ecommerce platform covers the full comparison.

Choosing a domain

Your domain is your address and part of your brand. A good domain is:

• Short and easy to spell when someone hears it said aloud.
• Free of hyphens and numbers, which people forget or mistype.
• On a trusted extension: .com for a global or US audience, .co.uk if you focus on the UK.
• Registered in your own name, so you control it if you ever change platform.

Check that matching social media handles are available before you commit to a name.

Step 4: Build product pages that sell

Your product page does the job a salesperson does in a physical store. It must answer questions, remove doubts and make buying easy.

A few principles for beginners:

• Photos first. Use natural light and a clean background, and show the product from several angles and in use. Customers cannot touch the product, so images do the work.
• Write for one person. Describe the product the way you would explain it to a friend who is about to buy it. Lead with benefits, then list specifications.
• Be honest about details. Exact dimensions, materials and care instructions prevent disappointed customers and returns.

For a deeper checklist, read our article on the 7 parts of a product page that sells.

Beyond product pages, you need a homepage that explains who you are and what you sell, an "About" page with your story, a contact page, and your policy pages. Keep your navigation short and organize products into categories that match how customers search.

Step 5: Set up payments

Customers abandon checkouts when their preferred payment method is missing or the process feels unsafe. Offer:

• Cards through a trusted payment provider.
• Digital wallets such as Apple Pay, Google Pay or PayPal, which make mobile checkout much faster.
• Buy now, pay later options if your products have a higher price and your audience expects them.

Show security signals that matter: a secure connection (HTTPS), clear contact details and recognizable payment logos. Keep the checkout short and allow guest checkout, because forcing account creation drives people away.

Step 6: Set up shipping and returns

Shipping is where many new stores lose money without noticing. Decide:

1. Packaging: sized to your products, protective, and ideally consistent with your brand.
2. Carriers: compare options for your typical parcel size, weight and destination.
3. Pricing strategy: charge actual rates, use flat rates, or offer free shipping above an order value. Whichever you choose, include shipping in your margin calculation.
4. Delivery promises: state realistic dispatch and delivery times and keep them.
5. Returns: a clear, fair return process builds trust. Decide who pays return shipping and how fast you refund. Our guide on reducing ecommerce returns covers this in depth.

Step 7: Place test orders before you launch

Before telling anyone about your store, buy from it yourself. Go through the whole journey as a customer would, ideally on a phone:

• Find a product from the homepage and through search.
• Add it to the cart, apply a discount code and check the totals.
• Pay with a real card and with a wallet.
• Check the order confirmation email: is it clear, branded and correct?
• Pack and ship the order, then check the tracking email.
• Request a return and process a refund.

Ask a few friends to do the same on their own devices and tell you where they hesitated. Fix everything before launch.

Step 8: Launch and win your first customers

Launching quietly is normal. Your first customers usually come from people and channels you already have access to, not from big campaigns.

• Your network: friends, family, colleagues and communities you belong to. Ask them to share, not just buy.
• Social media: show your products, your process and the people behind the store. Consistency beats perfection.
• Email list: collect addresses from day one with a simple offer, and send updates when you have something worth saying.
• Search: set titles and descriptions for every page, and plan a few helpful guides around questions your customers ask. Our ecommerce SEO guide explains how.
• Marketplaces: listing some products on a marketplace can bring early sales and reviews while your own store builds traffic. See multichannel ecommerce software for how to manage both.
• Paid ads: start small, with one channel and a clear budget limit, and only once your product pages and checkout convert.

Ask every early customer for a review. Reviews are social proof that new stores lack, and they help every future visitor decide.

Your first 90 days

The first three months are about learning, not scaling. Use them to understand what works and fix what does not.

Each week, look at a small set of numbers:

• Visitors and where they came from.
• Conversion: how many visitors became customers.
• Average order value and margin per order.
• Abandoned carts and why they might have happened.
• Questions and complaints, which show you what pages fail to explain.

Set up the automations that pay off early: order confirmation and shipping emails, abandoned-cart reminders (see our abandoned cart recovery guide) and a review request after delivery.

Example scenario: a ceramics maker opens an online store

Here is a hypothetical example. A ceramics maker sells mugs and bowls at local craft fairs and wants to reach customers between events.

1. Validation: Searches and questions at the fairs show that people look for handmade mugs as gifts. She checks competitors and finds few offer clear sizing and care information.
2. Basics: She registers as a sole trader, opens a separate bank account and speaks to an accountant about tax.
3. Platform: She picks a hosted platform with a free plan so she can launch without upfront costs, and registers a short domain in her own name.
4. Product pages: Each piece gets photos in natural light, a photo held in a hand for scale, capacity, dimensions and care instructions.
5. Shipping: Because ceramics are fragile, she tests her packaging by shipping a few orders to friends before launch.
6. First customers: She emails her fair customers, adds a card with the web address to every in-person sale, and asks early buyers for reviews.
7. First 90 days: She notices most questions are about dishwasher safety, so she adds that to every product page.

The lesson: a successful first store is built on validated products, honest pages and steady improvement, not on a perfect launch.
