How to Start an Ecommerce Business: Your First Product, Offer and Funnel in 2026

Americans filed 5.67 million applications to start a business in 2025, the highest yearly total since the Census Bureau's business formation data began in 2004. Retail trade accounted for 1.17 million of them, another record, and the pace hasn't slowed: applications from January to August 2026 ran 13.5% ahead of the same months in 2025.

Retail business applications in the US climbed to a record 1.17 million in 2025.

Thinking about how to start an ecommerce business from scratch? You'll be launching alongside a lot of new stores. A funnel-first route keeps the launch small: one product, one clear offer and a short path from ad to checkout, built in Funnelish.

1. Choose What You'll Sell and Who Ships It

When you plan how to start an ecommerce business, pick the product before anything else. It'll set your margin, your shipping costs and the kind of ads you can run.

Look for something you can explain in one sentence and show in use. If it fixes an obvious problem, like a bored dog chewing the sofa, you've already got your landing page headline.

Then decide who'll hold the stock. You can buy inventory and ship it yourself, have a supplier ship each order, use a print-on-demand partner or sell a digital download.

Four ways to fulfill orders, from buying stock upfront to selling files with nothing to ship.

How to Start an Ecommerce Business Without Inventory

With dropshipping, print on demand or digital products, you'll take the order first and pay for the product afterward. That trade costs you some control over margins and delivery times, and it'll keep far less of your cash tied up in boxes.

If your supplier ships from abroad, check this year's duty changes before you set a price. Since 24 June 2026, a CBP de minimis suspension has removed the $800 duty-free allowance for parcels arriving by express carrier or freight, and mail shipments lost it a month later. Duty and customs entry fees have become part of your cost per order.

Funnelish's order fulfillment tools can pass orders to a supplier through Google Sheets field mapping or Zapier's 4,000-plus integrations. They'll also bundle orders during a wait period you choose.

2. Test Demand Before You Buy Stock

Are you learning how to start an online ecommerce business? Run a small test before you order 500 units.

Build one landing page with the product, a price and a buy button, then send a few hundred visitors to it from ads or creator posts. Eric Ries called this a minimum viable product in The Lean Startup: the smallest version of an idea that'll tell you whether people want it. If nobody reaches checkout, you've found out for the price of a few ads.

Funnelish can A/B test two versions of that page, and its funnel analytics report the conversion rate for each step. You'll see which headline or price brought more buyers to checkout.

3. Register the Business and Set Up Payments

Under the SBA's guide to business structures, you're a sole proprietorship if you do business without registering as anything else. An LLC can protect your personal assets from business debts in most cases, though forming one means paying a state filing fee.

Next, get an employer identification number, or EIN. The IRS issues EINs free online and it's warned applicants about websites that charge a fee.

Don't leave sales tax until orders start arriving from other states. In its 2018 ruling in South Dakota v. Wayfair, the Supreme Court decided that states could require out-of-state sellers to collect sales tax without a physical presence. South Dakota's law covered sellers with more than $100,000 in sales or 200 or more separate transactions a year in the state, and other states have set their own thresholds since.

Payments are the last setup task in how to start an ecommerce business. Funnelish connects to Stripe, Checkout.com, Airwallex and NMI for cards, along with PayPal, Apple Pay, Google Pay and Klarna, and it doesn't add extra processing fees on any plan. Your gateway still takes its cut: Stripe's pricing lists 2.9% plus 30¢ per successful domestic card charge.

4. Build Your Store as a Funnel

A sales funnel walks each buyer from an ad through a landing page, checkout, upsell and thank you page. Once you've decided how to start an ecommerce business online with one product, you won't need a catalog, a menu or a search bar.

Each step can add to the order. An order bump on the checkout offers a small extra with one tick. After payment, a one-click upsell can offer a bigger one without asking for card details again. Has the buyer turned the upsell down? A downsell can offer the same item for less.

In Fetchlio, a free Funnelish template for a dog toy store, a $38.99 order grows to $78.97 when the buyer takes the order bump and the upsell.

Build the steps in the Funnelish funnel builder and edit each page by dragging blocks into place, without writing code.

How Much Does It Cost to Start an Ecommerce Business?

Software won't be your biggest bill. Funnelish's Basic plan costs $49 a month, or $41 a month billed yearly, and it includes 20 funnels, 20,000 visitors a month and a 14-day free trial.

What you spend beyond that depends on the model you've picked for how to start an ecommerce business. Stock, samples and photos can swing the total a long way, and in the example below, you'll spend the most on the ad test.

How much does it cost to start an ecommerce business with one product? Here's an example first month.

Drop the stock line and dropship instead, and you'd spend about $593 that month. You'd pay for that saving with a thinner margin on every order.

How to Start an Ecommerce Business on Amazon

Selling on Amazon puts shoppers in front of you on day one. Amazon's seller pricing lists two plans: Individual at $0.99 per item sold and Professional at $39.99 a month. On top of the plan, there's a referral fee on each sale, set as a percentage by category with a minimum charge. For electronics accessories, the rate was 15% on the first $100 of the price when we checked in September 2026.

That's a big channel. Amazon's small business report said independent sellers accounted for more than 60% of sales in its store, and US sellers averaged more than $375,000 in annual sales in 2025.

Before you decide how to start an ecommerce business on Amazon or in a funnel of your own, run both sets of fees on a single order. At a 15% referral fee, Amazon would keep $5.85 of a $38.99 sale before fulfillment fees, while a Stripe charge would cost $1.43 and Funnelish wouldn't add anything on top.

Per-sale fees and plan costs for a $38.99 order at 100 orders a month, with Amazon's fulfillment fees left out.

Have you wondered how to start an ecommerce business like Amazon? The company sold books online before it added other categories, and one category makes a sensible first step for you too. In Working Backwards, two former Amazon executives described how the company's teams wrote a press release for a product before they built it.

There's nothing wrong with running both channels side by side. Amazon's seller policies limit how you can contact its customers, and your own funnel, fed by your own ads and emails, is where you'll keep the customer relationship without a referral fee.

5. Find Your First Buyers

Where shoppers start looking has shifted. Salesforce's State of Commerce report found that agentic search, where people ask an AI assistant to find and compare products, grew 200% in a year as the first step of a purchase.

Start with one paid channel and one organic one. Short creator videos can show the product in use, and a Funnelish blog gives search engines and AI assistants pages about your product to find.

Whichever path you've taken on how to start an ecommerce business, track cost per buyer from day one. Does a buyer cost more to win than the first order earns? You'll need the bump and upsell from step 4 before you raise your ad spend.

Launch With a Free Funnel Template

Fetchlio, a free Funnelish template, comes with every step above already built for one product, a smart interactive dog ball. It's a working example of how to start an ecommerce business around a single offer and a full funnel.

Its home page opens with "A Smarter Way to Beat Boredom & Keep Your Dog Happy." On the landing page, buyers can choose one ball for $38.99, two for $78.98 or three for $106.97, with a 4.8 score from more than 1,200 ratings shown above them. Checkout shows the bundles again, with a $9.99 protective cover added as an order bump.

When you click through the funnel, the one-time offer after payment pitches an extra ball for $29.99, and the downsell brings that price to $19.99. The confirmation page then hands buyers a 10% discount code for their next order.

Fetchlio walks buyers from the landing page through checkout, the upsell and the downsell.
