How to Start Ecommerce in 2026: Customers First, Then Stock

Quick answer: To start an ecommerce business in 2026, find your customers before you buy your stock. Pick one clear type of customer, build a small audience with content, test demand with small batches, pre-orders or marketplace listings, and only scale stock once people are actually buying. Put your early money into reaching and learning from your first 100 customers, not into a big first order.

Here's a story we see again and again. Someone spends £5,000 on a container of products, builds a beautiful website, launches, and waits. The orders don't come. Six months later the stock is still in the spare room and the money has gone. The product often wasn't the problem. The problem was that nobody knew it existed, and nobody had checked whether the people it was made for actually wanted it.

At Tekovex we manage stores on eBay, Etsy, Amazon, TikTok Shop and Shopify, and our client stores have passed £1 million in UK sales. The stores that grow almost always started the other way round: customers first, stock second. Here's how to do it in 2026.

Why 2026 is still a good year to start, and why it's harder

• The market is big: 28.8% of all retail sales in Great Britain were made online in August 2026, according to the Office for National Statistics.
• Social selling is booming: TikTok Shop now has 300,000 UK small business sellers, new sellers grew 200% year on year, and sales from TikTok Shop Live rose 55%, as Retail Gazette reported in July 2026.
• But customers cost more: research by SimplicityDX found brands were losing $29 on every new customer in 2022, up from $9 in 2013, a 222% rise, and that acquisition costs had climbed by as much as 60% in five years (Business Wire).

So there are more buyers online than ever, but getting each one costs more. That's exactly why your first pounds should go on learning how to reach customers cheaply, not on stock you'll struggle to sell.

What "customers first, stock second" really means

It doesn't mean "spend everything on ads". It means your early money and time go on three things before a big stock order:

• Finding out who buys: one specific customer with one specific problem.
• Reaching them cheaply: content, communities, creators and marketplaces where they already shop.
• Proving they'll pay: real orders, pre-orders or a waitlist, not compliments from friends.

Stock is the last step, and you buy it in small batches that real demand has already justified.

Real brands that did it this way

• Gymshark: Ben Francis started in 2012 by dropshipping supplements and clothing, holding no stock, and the first order took two months to arrive. He sent clothes to fitness YouTubers he admired, and the community did the rest. At the BodyPower Expo in 2013, the site went from about £300 a day to £30,000 in 30 minutes (The Official Gymshark Story).
• Glossier: Emily Weiss launched the beauty blog Into The Gloss in 2010 and built an audience of 2–3 million monthly visitors before launching Glossier in 2014 with just four products (Contrary Research). The audience came first; the products were designed around what readers wanted.
• Rose & Caramel: Rosie Greenhalgh developed tanning products alongside her salon in Bolton for years before going full time. In one year the brand quadrupled turnover and sold over 35,000 products through its own website (Cosmetics Business). It's now one of the UK brands growing through TikTok Shop.
• Enchanted Scrunch: founder Dasha Derkach's first TikTok video got 15,000 views and 10 orders on day one. Posting consistently took the business from about 2 orders a week to around 500 (Shopify).
• UK live sellers in 2026: Glow For It made £100,000 in a single TikTok Shop live session, and Malik Butchers sold £8,000 of meat in one three-hour broadcast, about 3–4 days of high-street sales (Retail Gazette).

Different products, same pattern: they earned attention and trust first, then sold to people who were already waiting.

Step 1: Choose a customer, not a product

"I want to sell phone cases" is a product. "Nurses who need a phone case that survives a 12-hour shift and wipes clean" is a customer. The second one tells you where to find buyers, what to say, and what to make. Write one sentence describing your customer and their problem before you look at a single supplier.

Step 2: Build a small audience before you buy stock

• Post short videos on TikTok, Instagram or YouTube about the problem, not the product.
• Join the places your customer already talks: Facebook groups, Reddit, forums, local communities.
• Collect emails with a simple waitlist page: "Get first access and 10% off launch day".
• Aim for your first 100 to 500 genuinely interested people. That's enough to test a launch.

Step 3: Test demand cheaply

• Marketplace test: list a small batch (10–30 units) on eBay, Etsy or TikTok Shop. Marketplaces already have buyers, so you learn fast.
• Pre-orders: take orders before you've made the stock, with an honest, clearly stated dispatch date.
• Samples to creators: send 10–20 samples to small creators in your niche and watch which videos make people ask "where can I buy this?"
• Small ad test: spend £100–£200 on ads pointing to a product page or waitlist and measure clicks and sign-ups.

Decide your pass mark before you start, for example "30 orders in 30 days" or "300 waitlist sign-ups". If you hit it, buy more stock. If you don't, change the offer, not your bank balance.

Step 4: Split your starting budget the right way

Here's how we'd split a £2,000 starting budget for a physical product:

• Samples and a first small batch: £600–£800
• Content, creator samples and small ad tests: £600–£800
• Packaging, postage and marketplace fees: £200–£300
• Reserve for reorders of what sells: £300–£400

Notice that reaching customers gets as much money as stock does. Most failed launches we see spent 90% on stock and almost nothing on being found.

Step 5: Remove the reasons people don't buy

Getting visitors is only half the job. Baymard Institute's research across 50 studies puts the average online cart abandonment rate at 70.22%. The top reason, given by 40% of shoppers, is extra costs such as delivery and fees, followed by slow delivery at 20% (Baymard Institute).

• Show the full price, including delivery, early.
• Offer guest checkout. Don't force account creation.
• Dispatch quickly and say so clearly.
• Show real reviews and a simple returns policy.

Step 6: Keep the customers you've paid for

Because acquiring customers is expensive, every repeat purchase is close to pure profit. Research by Frederick Reichheld of Bain & Company found that increasing customer retention by 5% increases profits by 25% to 95%, and acquiring a new customer costs 5 to 25 times more than keeping one (Harvard Business Review).

• Add a handwritten thank-you note or small extra in every order.
• Email buyers with useful tips, not just discounts.
• Launch new products to existing customers first.
• Ask every happy customer for a review.

Step 7: Choose your channels in the right order

• Start on a marketplace (eBay, Etsy, Amazon or TikTok Shop) where buyers already are.
• Add social selling once you have content that works, especially TikTok Shop and live selling.
• Open your own Shopify store once you have repeat customers and an email list to send there.

The 90-day plan

• Days 1–14: define your customer, research competitors, order samples.
• Days 15–45: post content daily, build a waitlist, send creator samples.
• Days 46–60: run your demand test: marketplace batch, pre-orders or small ads.
• Days 61–90: reorder only what sold, cut what didn't, and start emailing your first customers.

Frequently asked questions

How do I start an ecommerce business in 2026?

Choose one specific customer, build a small audience with content, test demand with a small batch or pre-orders, then scale the products that sell.

Should I buy stock before launching?

Only a small test batch. Use pre-orders, marketplace listings or a waitlist to prove demand before you place a large order.

How much money do I need to start ecommerce?

You can test with a few hundred pounds on a marketplace. A £1,000–£2,000 budget lets you split money between stock, content and customer testing.

What is the best platform to start selling online in the UK?

A marketplace such as eBay, Etsy or TikTok Shop is usually best to start, because buyers are already there. Add your own store later.

Is ecommerce still profitable in 2026?

Yes, for sellers who control acquisition costs and keep customers coming back. Online sales are 28.8% of GB retail, but customers cost more to win than ever.
