Why ChatGPT gets your prices wrong, and how to fix it

ChatGPT gets your prices wrong because it quotes the last version of your price that it read, and that version can be days out of date or sit on a page you forgot about. The fix is to state one price plainly on your own site, repeat it identically everywhere else, and then check what ChatGPT says every week.

We know because we watched it happen. When GetLean Clinic cut its starting price, ChatGPT took a few days to catch up, and it kept repeating a detail the clinic's site had just removed.

What we saw

GetLean cut its monthly starting price from S$388 to S$288 on 3 October 2026. We asked ChatGPT, logged out and from Singapore, on two days:

5 October: it quoted S$388, the old price, two days after the cut.
7 October: it quoted S$288, the new one.

So ChatGPT picked up the new price within four days. One price change is one data point, not a rule, but it gives you a rough sense of the timescale.

Two other things came out of the same tests:

ChatGPT does read your prices. It quoted GetLean's "from S$288/month" in every answer that gave a price.
It also repeats what you have just deleted. ChatGPT quoted a follow-up schedule that GetLean's site had only just removed.

The lesson is that ChatGPT lags your website by days. Whatever your site said last week is what ChatGPT may still be telling customers this week.

Why ChatGPT's version of your price goes wrong

There is nothing mysterious about it. These are the usual causes, in the order I would check them:

An old price still exists somewhere. An old PDF price list, last year's promotion page, a pinned Facebook post, a directory listing or a WhatsApp Business auto-reply. ChatGPT can only quote what it finds, and it doesn't know which page you meant to be the current one.
Two pages disagree. Imagine a tuition centre in Bishan whose homepage says "from S$280 a month" while its Google profile says "from S$250". Customers, and ChatGPT, will meet both.
GST is shown differently. If one page shows prices before GST and another after, ChatGPT may quote either, and your customer finds out at the counter.
There is no price at all. If you don't publish one, a customer asking "how much does it cost" may get an answer that leans on other businesses' prices instead of yours.
ChatGPT hasn't re-read your site yet. Even when everything is fixed, expect a delay of a few days, as GetLean's change showed.

How to fix it

1. Put one price on one clear page

Make a plain pricing page. Give a "from" price for each service, say whether GST is included, and add a line such as "Prices correct as at [date]". If you are a renovation contractor, "from" prices by type of job (for example, a bathroom in a 4-room HDB flat) are far more useful than "contact us for a quote".

2. Make every other place say the same thing

Go through this list and make the price match your pricing page:

Your homepage and any service pages
Your Google Business Profile (the services and prices section)
Facebook, Instagram and LinkedIn bios and pinned posts
Directory and marketplace listings
WhatsApp Business profile and auto-replies
PDF brochures, menus and quote templates
Old promotion pages that are still online

3. When a price changes, change everything on the same day

Update the pricing page first, then work down the list above. Delete or redirect old pages and PDFs rather than leaving them online next to the new ones. An old page that still exists is a page ChatGPT can still read.

4. Re-test a few days later

Ask ChatGPT the same price question you asked before the change. Because GetLean's new price showed up within four days, a sensible habit is: change it on Thursday, re-test after the weekend. If the old price is still there after a week, look at the sources ChatGPT lists under its answer. They can point you to the page you missed.

5. Check every week

Prices creep back out of sync. Someone updates the website but not the booking page, or a supplier's listing keeps the old figure. A weekly check with the same wording catches it. Our guide to checking what ChatGPT says about your business has a ten-minute method and a table you can copy, and "price quoted" is one of the things to record.

What you can't control

You can't make ChatGPT re-read your site on a schedule. One logged-out answer is also only a snapshot: ask the same question again and the answer may change. If ChatGPT keeps quoting something wrong and you can't find where it came from, write down the wrong answer and the date, keep your own pages correct, and test again next week.
