Guide
Start a product-based business
Sector-agnostic guide to starting a product business covering sourcing, stock management, storage, packaging, labelling, product safety, and pricing.
Selling physical products requires more upfront investment than a service business, but offers the potential for higher margins and scalability. Success depends on getting the fundamentals right before you launch — reliable sourcing, proper labelling, and safe products.
Finding and vetting suppliers
Your supplier is your most important business relationship. A reliable supplier delivers consistent quality on time. An unreliable one can destroy your reputation and cash flow.
- Domestic suppliers: Higher unit costs but shorter lead times, easier quality control, and no customs duties. Search trade directories and attend trade shows.
- Overseas suppliers: Lower unit costs but longer lead times (4-12 weeks from Asia), customs duties, and UKCA/CE marking requirements. Always get samples before placing bulk orders.
- Vetting checklist: Request samples, check references, start with a small trial order, agree payment terms in writing, and confirm they can scale if demand grows.
Storage and fulfilment options
- Home storage: Free but limited. Check your home insurance covers business stock and your council permits home-based business. Not suitable for food or hazardous products.
- Self-storage units: £50-300/month depending on size and location. Flexible terms, good for small to medium volumes.
- Fulfilment centres: Third parties store your stock and ship orders for you. Charges per item stored and shipped. Cost-effective for online sellers with high order volumes. Amazon FBA is one option.
- Shared workspace: Some makerspaces and shared workshops offer storage alongside production facilities.
Pricing your products
Many new product businesses underprice. Calculate your true cost per unit before setting prices:
- Direct costs: Materials, components, packaging per unit
- Labour: Your time or employee time to produce/pack each unit
- Overhead allocation: Rent, utilities, insurance, software — divided across expected units
- Shipping: Postage, packaging materials, courier fees
- Platform fees: Marketplace commissions (Etsy 6.5%, Amazon 8-15%, eBay 10-13%)
- VAT: If VAT registered, factor in 20% VAT on sales
Add your profit margin on top. Research what competitors charge for similar products. If your costs mean you cannot compete on price, you need a differentiation strategy (quality, branding, niche targeting).

Source and test samples
Find 2-3 potential suppliers and order samples. Compare quality, lead times, minimum order quantities, and pricing before committing to one supplier.

Calculate your true cost per unit
Include materials, labour, packaging, shipping, platform fees, and overhead. Only then add your profit margin. If the final price is uncompetitive, rethink your supply chain.
-
Check product safety requirements
Ensure your product meets UK safety standards. Check if your product category has specific regulations (toys, electrical, cosmetics, food). The Office for Product Safety and Standards (OPSS) provides guidance.

Set up stock tracking from day one
Use a simple spreadsheet or inventory app to track stock levels, reorder points, and sales. This prevents stockouts and overordering.
