Your Own Store (Shopify) vs. Marketplaces: The Data You Can Actually See Is Different
Published: 2026-07-29
In short
On your own store (Shopify), you have near-unrestricted access to raw, order- and customer-level data. On marketplaces (Rakuten, Amazon, ZOZOTOWN, Yahoo! Shopping, and others), you can only see data at whatever granularity the marketplace's seller dashboard provides, and certain data — customer information in particular — is often deliberately withheld. This is a structural design choice marketplaces make to protect their ownership of the customer relationship on their own platform, and it isn't something a seller can fix through effort alone.
Introduction: The Same "Sales Data" Doesn't Mean the Same Level of Detail
When you try to view data across multiple marketplaces at once, you quickly notice that the granularity available on your own store (Shopify) is fundamentally different from what marketplaces offer. Information you can take for granted on your own store often turns out to be visible on a marketplace only within whatever range its seller dashboard happens to expose.
Your Own Store (Shopify): Access to "Your Own Database"
On a direct-to-consumer platform like Shopify, order, customer, and inventory data fundamentally belongs to you as the merchant, and you can access nearly all of it freely — through dashboard exports or the API. You can capture and use customer-level purchase history, or even which channel a given customer arrived through, entirely at your own discretion.
Marketplaces: You Only See What the Marketplace Chooses to Show
On a marketplace, by contrast, the data a seller can view is limited to whatever range the marketplace's own seller dashboard provides. Customer personal information and detailed behavioral data in particular are often deliberately withheld from sellers by design. It's more accurate to understand this not as a technical limitation but as a structural choice: marketplaces are protecting their ongoing control over the customer relationship on their own platform. The underlying assumption is that even when a seller acquired a customer through the marketplace, the customer data itself remains the marketplace's asset.
This Gap Makes Cross-Channel Analysis Difficult
On your own store, you can freely analyze data at the level of product x customer x time period. On marketplaces, you may only be able to get data down to product x time period. If you try to line up data across channels without accounting for this gap in granularity, you tend to end up with a lopsided picture — your own store looking unusually detailed, and every marketplace showing only broad numbers. Before comparing across channels, you need to first understand exactly how granular a data each marketplace makes available.
- Check each marketplace's seller dashboard to see exactly how granular the data is by product and by time period.
- Understand that customer-level data is, in practice, only available from your own store.
- Recognize that data granularity on marketplaces isn't something you can change through effort — it depends on how the marketplace is designed.
- Design your cross-channel analysis around the lowest common denominator of granularity — such as product x marketplace x time period — that every channel can actually provide.

Frequently Asked Questions
Q. Is there any way to get customer-level data from a marketplace?
In some cases, limited information can be obtained within the marketplace's dashboard and terms of service, but it's usually far less flexible than what your own store provides. Since the terms and the scope of available data differ by marketplace, you'll need to check each marketplace's terms and dashboard specifications individually if you need this.
Q. How should we handle cross-channel analysis when granularity doesn't match?
The practical approach is to design your analysis around whatever granularity is common to all marketplaces — such as product x marketplace x time period. Detailed data that's only available from your own store can then be used separately, as a standalone analysis of that channel.
Q. Can we negotiate with a marketplace to get access to more data?
This depends heavily on the marketplace's terms and operating policy, and the range that can actually be changed through individual negotiation tends to be limited. It's more realistic to treat the difference in data granularity as a given constraint and focus your energy on how to design cross-channel analysis within it.
Facing this kind of challenge?
For sellers running two or more of Rakuten, ZOZOTOWN, and their own store (Shopify), we build a dashboard that consolidates data across marketplaces and deliver a weekly AI-annotated report focused on the metrics that matter for your industry. A free diagnostic is also available to check your current data-integration status.
