Facebook Pixel Tracking wrong Purchase Value

(Note: Updated for current Funnelish V2 instructions)

If you are noticing your Facebook Pixel tracking inflated purchase values (for example, a $50 purchase reporting as $200), this is almost always caused by overlapping scripts or incorrect product configurations.

In the modern Funnelish builder, here is how to fix this:

  1. Remove hardcoded scripts: Go to your Custom Codes section and delete any manual Facebook Pixel base scripts you might have pasted. If you leave a manual script while the Funnelish FB App is running, FB often gets confused and multiplies the value.
  2. Use the Native App: Ensure your pixel is exclusively running through Funnel Apps > Facebook Pixel.
  3. Check Product Prices: The native integration pulls the exact purchase value directly from the Products tab in your funnel. Ensure the price listed in the settings exactly matches what you are actually charging.

The native app is designed to pass the exact itemized value per step (Order Form, Order Bumps, OTOs) to keep your ROAS 100% accurate.

The Facebook Pixel App is over-inflating the Purchase Value. Where customers have bought for $50 for example it shows $200 in purchases which is not true.

How can this be fixed?

Can you try the pixel helper, because it’s not a single case by case issue, I mean it could be that FB inflated the value or double fired the pixel (which happens sometimes).

Or, if it happens a lot, then do you have any custom pixel code in your funnel or funnel steps? check them for any custom pixel code that might be firing without you knowing, but again the Facebook Pixel helper should be more than enough…

Hey @samlee I checked and it does not double fire the pixel.

The number of purchases is always correct but it is just the value of each purchase that gets inflated.

Can you look into it as it makes it very hard for us to track ROAS in FB like this.

Ok, PM us the URL of that page where the value is fluctuated
