1. Confirm the exact product
Match the retailer product to the Amazon listing. Check the brand, model, EAN or ASIN, pack size, variation, colour, size, condition, expiry information and included accessories. A similar title or photograph is not enough. Amazon says listings use product identifiers and offer details to specify what is being sold.[3]
2. Check that you are allowed to sell it
Check your Seller Central eligibility before buying. Some categories require approval, some brands or products are restricted, and FBA has its own restrictions.[3] Do not assume that another seller's offer proves that your account is authorised.
3. Check demand and competition
Review price history, current offers, Buy Box behaviour, sales-rank context, Amazon presence and likely sell-through. Historical data is evidence, not a forecast. Consider how many sellers compete, whether stock is seasonal and whether the current price is unusually high.
4. Check the full cost
Record the purchase price, delivery, preparation, labels, inbound shipment, referral fee, fulfilment, storage, returns, advertising, VAT and any import charges. Use the FBA profit calculator and compare the result with the UK FBA cost guide.
5. Check VAT and imports
Decide whether your figures are VAT-inclusive or net and keep the treatment consistent. If goods are imported or moved across a UK border, check the EORI and customs position before ordering.[6][7] Do not treat VAT or import costs as an afterthought.
6. Check product and account risk
Look for IP concerns, Hazmat indicators, category approval, expiry dates, safety documentation, authenticity evidence, batteries, liquids, fragile packaging and restrictions on condition. If you cannot explain the supply chain or provide acceptable evidence, pause.
7. Decide a maximum buy price and quantity
Set a maximum buy price that leaves room for a lower sale price, fees, returns and slower sell-through. Choose a quantity that matches your cash available and your ability to hold stock. A theoretical ROI does not tell you how quickly the money will return.
8. Save the decision record
Record the source URL, time checked, product identifier, purchase price, expected sale price, fee assumptions, VAT basis, expected ROI, maximum buy price, quantity, risk flags and recheck date. Keep the supplier invoice and order confirmation with the decision record.
Stop conditions
Do not buy when the listing match is uncertain, eligibility is unconfirmed, required evidence is missing, the economics work only at the current price, the product is restricted, the supplier cannot be traced or the stock quantity is beyond your cash and storage tolerance.
