Meta said there were 42 purchases. Shopify recorded only 27.
So... where did the other 15 come from?
If you've ever compared your Meta Ads results with your Shopify sales and felt confused, you're not alone.
This is one of the most common questions I hear from business owners.
The first reaction is usually:
"Meta is overreporting."
But that's not always true.
Here's what could be happening:
📌 Meta may be using a different attribution window.
📌 Some customers clicked your ad but completed their purchase days later.
📌 A customer may have interacted with multiple ads before buying.
📌 Your website's tracking could be missing events or firing them more than once.
📌 The Meta Pixel and Conversions API might not be deduplicating events correctly.
In other words, the numbers don't always match and they aren't supposed to.
The real question is:
Do you understand why they don't match?
Without that understanding, it's easy to pause profitable campaigns, increase budgets in the wrong places, or lose confidence in data that is actually telling an important story.
Good marketers don't expect every platform to report identical numbers.
They know how to interpret the differences.
That's what separates informed decisions from expensive guesses.
💬 Have you ever compared Meta Ads with Shopify, WooCommerce, or another e-commerce platform and noticed different purchase numbers? What was the biggest difference you've seen?
If your Meta Ads, GA4, and e-commerce reports are telling different stories, don't ignore it.
