The most common reason Shopify stores fail isn't the platform, the design, or the marketing - it's the product. A store selling something nobody wants, or something where all the margin is captured by large established players, doesn't succeed regardless of how well it's built. Finding the right product is more important than everything else combined.
Start with demand evidence, not product ideas
The mistake most new sellers make is starting with a product they like and then looking for demand. The better approach is finding existing demand and then finding a way to serve it.
Google Trends. Enter product ideas or problem categories and check whether search volume is growing, stable, or declining. A product with rising search trend has tailwind. A declining trend requires either a specific angle on why your version is different or a willingness to fight for a shrinking pie.
Amazon BSR (Best Seller Rank). Look at the bestseller lists in relevant Amazon categories. Products consistently ranking in the top 100 of their category have proven demand. The question becomes whether you can compete on quality, price, niche, or brand.
Etsy search and sales estimates. Etsy's search autocomplete and tools like Marmalead show what people are actively searching for in handmade and unique goods. High search volume with fewer established sellers indicates an underserved gap.
Reddit and niche communities. Communities around a hobby, interest, or lifestyle often complain about products that don't exist or products that exist but are poor quality. These complaints are product ideas. "I can't find a good [X] for [Y]" is a business opportunity if it's said frequently enough.
Evaluating product viability
For any product you're considering, answer these questions before committing:
Is the margin viable? What does it cost to produce or source? What will customers pay? After Shopify's fees, shipping, and customer acquisition cost (assume £10–£15+ per new customer via paid advertising), is there enough margin left to build a sustainable business? A product that costs £8 and retails at £20 has almost no margin after acquisition and fulfilment costs. A product that costs £8 and retails at £60 can work.
Is it defensible? Can a large retailer or Amazon easily copy it and undercut you? Products with genuine differentiation - handmade, customised, a strong brand story, unique materials, or a proprietary formulation - are harder to commoditise. Generic products with no differentiation compete only on price.
Can it be shipped profitably? Heavy, fragile, or temperature-sensitive products have shipping costs and breakage rates that can make the unit economics unworkable for a small brand. Products that are lightweight, durable, and non-perishable are logistically simpler and cheaper to ship.
Is there a repeat purchase dynamic? A product someone buys once and keeps for ten years requires constant customer acquisition. A consumable that runs out every 4–6 weeks creates natural repeat purchase. For building a sustainable business with lower ongoing acquisition cost, repeat purchase products have a significant structural advantage.
Sourcing approaches
Manufacturing your own. Maximum control, maximum quality, maximum investment. If you make the product yourself - skincare, jewellery, food, clothing - you have full differentiation and no minimum order anxiety. The constraint is scale: you can only make so much.
UK/EU manufacturers and white-label. Commission a manufacturer to produce your product to your specification, with your branding. More investment upfront (minimum order quantities, formulation costs) but full brand control and higher margins than reselling. Many product categories have small-batch UK manufacturers willing to work with emerging brands.
Sourcing from trade shows and directories. UK trade shows (Spring Fair, Top Drawer, Autumn Fair) and wholesale directories (Faire, Ankorstore) connect you with brands willing to sell wholesale for resale. Lower margin than own-brand but lower risk and investment.
Dropshipping suppliers. Zero inventory risk but thin margins and limited brand control. Right for testing demand before committing to inventory, not as a long-term high-margin business model for most product categories.
The validation step before building
Before building a full Shopify store and ordering inventory, validate that people will actually pay for your product:
- Sell on Etsy or eBay with minimal setup - real sales from real customers before a full store investment
- Pre-sell: announce the product, take deposits, and only produce if you hit a minimum. Kickstarter and Indiegogo exist specifically for this
- Run a minimal Facebook or Instagram ad to a simple landing page to measure interest before building
The goal: get real purchase data before significant investment. A customer paying £30 for your product is stronger validation than ten people saying they'd buy it. Build the full Shopify store once you have evidence that matches the ambition of what you're building.
