A Grok research brief for supplier quotes
Direct answer
Give Grok a fixed brief for supplier research: three companies, their websites, and a price only when that price is printed on the page you are given. Open every link before you trust a figure or put it in a quote. Estimates are not allowed. Not live-tested yet.

Grok chat on a free or Plus plan may be enough. The X Subscription docs, updated 11 October 2026, list Plus at $8 a month and Premium at $30. They say Grok Bot is included from Premium upward and is not included on Plus. This playbook is a chat brief, not the Bot product. About £6 or £23 at the planning rate. Confirm x.ai pricing before you pay.
GBP figures are a budgeting conversion at £1 = $1.33 and €1 = £0.86, rounded to the nearest pound, fixed for this edition on 24 October 2026. They are not a live rate and not a quote. Vendor list prices are usually quoted before tax.

Who it is for
A sole trader pricing a job that depends on materials, a subcontractor, or a product they do not buy every week, and who will check the pages themselves.
Keep a note called Supplier checks with the prompt and a line for the date. When a price mattered, write the URL you opened. Six months later, when the same job comes back, you will not remember whether the number was real.
If the material is safety-critical, a datasheet and a supplier who will put the specification in writing matter more than a low unit price. The model is not a specifier.
What you need
- A Grok account on grok.com, on whatever plan you already have or are willing to read the price of.
- A specific thing you need, with constraints such as town, size, or a budget ceiling.
- Time to open the links. If you will not open them, do not use the answer.
Step by step
01
Brief it like a junior, not like a search box
Write what you need, the constraints, and what a useful row looks like. 'Find me a supplier' produces a confident paragraph. 'Find three UK suppliers of this exact material who publish a trade price, with the page URL' is a brief. Include whether the price must be ex VAT, and the unit, such as per metre or per box.
02
Use a prompt that forbids estimates
Paste this shape: list up to three suppliers; for each give the company name, the homepage, and a price only if it is written on a page you cite; quote the sentence the price is in and give the URL; if no price is published, write not published; do not estimate, convert, or recall a price from memory; if you are not sure the page is current, say so. Save the prompt. Change the product next time, not the rules.
03
Open every URL before the number travels
Click each link. Check the price, the unit, whether it is ex VAT, and any date on the page. If the link is dead or the price is not there, throw the row out. Do not average the gaps. Keep a note of the date you looked. A price you send to your customer should come from the supplier's page or from a quote they sent you, not from the model.
04
Check the company if you will pay them
For a UK limited company, look the name up on Companies House and see that it matches the site. A web page is not a contract and a low price is not a vetting. If you pay subcontractors in construction, the Construction Industry Scheme may apply. Reading a supplier page is not operating CIS. Ask your accountant or read the GOV.UK guide before you treat a search result as a hiring decision.
05
Regenerate once, then stop
If the answer includes an estimated price, delete it and run the prompt once more. If it happens again, the product is not following the brief today. Search yourself. Do not negotiate with the model until it produces a number you wanted. That number is the dangerous one, because you asked for it.
What can go wrong
A price with no sentence
If the row has a figure and no quoted sentence from the page, it is not a source. Drop it, even if the company is real. Real companies get attached to invented prices.
Currency and VAT quietly converted
A US list price turned into pounds at a rate the model chose is not a UK trade price. Keep the original currency and convert from a rate you can point at, such as the supplier's own GBP page or your card statement later.
Using the answer as the customer quote
Your quote to a customer is your document. Paste a supplier's published price into it only after you have opened the page, and say it can change. Better: ask the supplier for a quote and use that.
UK notes
Costs, including VAT
Budget £0 if the free allowance covers an occasional search, about £6 for Plus, or about £23 for Premium if you specifically want Grok Bot. Those are planning conversions of the 11 October 2026 list prices, before tax. The docs say tax may be added at checkout. A VAT-registered buyer of an overseas digital service should check the reverse charge rather than assuming the sticker price is the full cost.
Data flow
A research prompt that names your customer, their address, and their budget is personal data sent to xAI. You usually do not need to include the customer's identity to find a supplier. Leave them out. xAI's pricing and privacy pages describe the product. International transfers of personal data still need a UK GDPR basis and safeguard if you do include a person. Companies House data about a company is a different, public matter.
HMRC and Making Tax Digital
A supplier price is not your taxable turnover and it is not an allowable expense until you actually incur it. Keep the quote you rely on with the job file. Making Tax Digital does not require this research habit. If the job is construction and you pay a subcontractor, CIS has its own registration, deduction, and return rules on GOV.UK. This playbook stops before that process on purpose.
Practical orientation for a UK reader. Not tax, legal, or accounting advice.
Test log

Pending first test. The prompt and the checking rule were written from xAI's subscription docs and from the known habit of models estimating missing prices. No supplier search has been logged against live pages for this guide.

Questions people ask
Why Grok rather than a normal search?
A normal search is often better. Use this when you want a first list and you will verify it. The rule about opening links is the same if you paste the prompt into ChatGPT or Claude instead. The tool page explains which Grok plan includes the separate Bot product.
Can I ask it for three prices and average them?
No. An average of published prices can still hide a unit error, and an average that includes a guess is fiction. Quote a source or get a written supplier price.
What if the page is behind a login?
Then the model has not seen it, whatever it claims. Log in yourself or ask the supplier. Do not paste a trade-account password into the chat.
