Your own store is a channel like any other
Shopify, WooCommerce, Magento, PrestaShop, OpenCart, Wix and others connect the same way as a marketplace. The difference is on the money side: there is no marketplace commission, and the payment arrives from a processor as a collection.
Same orders, different money
On a marketplace the money arrives as a payout with commission already deducted. On your own store it arrives from a payment processor, with its own fee and its own settlement delay.
Describing both with one sentence would be wrong, so the product records them differently — and the channel comparison still works.
