As of 13 August 2026, AI can compare wholesale prices from UK suppliers.
Most people should hand this to a purpose-built tool.

What the alternative costsA purpose-built tool such as Parseur extracts data from invoices, emails and PDFs, but no alternative price is provided here.
If this goes wrong: you choose a supplier using a misleading unit price or missed delivery charge and pay more, receive the wrong quantity or disrupt your purchasing process.

How to actually do it
- Open the current quotes, price lists and supplier emails, and save the relevant files with clear supplier names and quote dates.
- Gather the product specification, required quantity, pack sizes, delivery postcode or delivery terms, VAT treatment and any minimum order requirements.
- Paste or attach the source documents in a chatbot with the comparison prompt, and state the unit you want prices normalised to, such as per kilogram, litre or item.
- Ask the chatbot to produce the comparison table and to flag any specification, VAT, delivery, lead-time or quote-expiry mismatch rather than filling gaps.
- Compare every price, pack size, delivery charge and condition in the draft table against the original quote, checking the displayed calculation for each normalised price.
- Ask the chatbot to recalculate any disputed row using the corrected source figure, then save the verified table with the source documents.
- Send the unresolved questions from the final list to the relevant suppliers and update the comparison when their written replies arrive.
Prompt
Compare the attached or pasted wholesale quotes from UK suppliers for [PRODUCT]. Use only the information in the supplied documents and do not invent missing figures. Create a table with supplier name, product description, pack size, quantity, quoted price, price per [UNIT], VAT status, delivery charge, minimum order quantity, lead time, payment terms, quote expiry date and any stated conditions. Convert prices to a consistent unit only when the pack size and quantity make that calculation reliable. Show the calculation for every converted price and keep VAT-inclusive and VAT-exclusive figures clearly separate. Do not treat different specifications, grades, pack sizes or delivery terms as equivalent. Flag any missing, ambiguous, inconsistent or expired information instead of guessing. Identify the lowest comparable delivered cost, but do not recommend a supplier until you list the reasons the options may not be directly comparable. Finish with a short list of questions I should ask suppliers before ordering. Source every row and calculation by naming the document, page, section or quote reference.

What it gets wrong
- AI cannot know whether two differently described products meet your operational or quality requirements.
- AI cannot reliably infer whether a delivery charge, rebate, credit term or minimum order condition applies when the quote is unclear.
- AI cannot provide current prices unless you supply current supplier documents or connect it to an authorised live source.
- AI cannot take responsibility for choosing a supplier or for the consequences of an incorrect order.
- AI does not replace supplier confirmation when the commercial terms are ambiguous.
Even on a YES, the friction has a name: real time truth, judgement under ambiguity and stakes of error.

FAQ
- Can ChatGPT compare supplier quotes?
- Yes. It can extract figures from pasted quotes or attached files, standardise comparable units and create a table showing prices and stated terms. Check every row against the original supplier document before using it to place an order.
- Can AI find the cheapest wholesale supplier in the UK?
- It can identify the lowest figure among the quotes you provide, including a calculated unit price where the pack sizes are clear. It cannot establish the cheapest current supplier without current quotes, and the lowest price may not be the lowest delivered or usable cost.
- Can AI compare prices including VAT and delivery?
- Yes, if the quotes state the VAT treatment and delivery charges clearly. Tell it to keep VAT-inclusive and VAT-exclusive figures separate, show its calculations and flag charges or terms that are missing.
- Is it safe to use AI to choose a wholesale supplier?
- It is suitable for preparing and checking a comparison, but you remain responsible for the buying decision. Confirm product specifications, availability, delivery terms and any ambiguous prices with the supplier before ordering.
