The arithmetic

Where checkout happens on the platform, a selling fee applies as a percentage of the order. Where the product tag links out to the seller's own site, there is no platform fee at all and the cost is the seller's own payment processing.

On-platform: net = price − platform selling fee − payment processing. Off-platform: net = price − own payment processing.

The two routes differ enough that they are separate commercial decisions rather than a configuration choice.

How that looks in practice

The $58 item with on-platform checkout at a 5% selling fee: $2.90, leaving $55.10 before fulfilment.

The same item sold through a tag linking to your own store: $1.98 of payment processing, leaving $56.02, $0.92 better, and the customer data, the email address and the remarketing permission stay with you.

That data is worth considerably more than $0.92 over a customer relationship, which is the real argument for keeping checkout on your own site.

Against it, on-platform checkout converts better because it removes a step, and for impulse purchases that difference can exceed the value of the data.

Where this breaks down

The fee comparison is trivial and the strategic difference is not. On-platform checkout means the platform owns the customer relationship; off-platform means you do.

Conversion differences also vary enormously by price point and by how well-known the brand is. An unfamiliar brand benefits far more from on-platform checkout than an established one.

Acting on it

Decide on the basis of customer ownership rather than the fee. For a business building a brand and a repeat customer base, the off-platform route is usually right despite converting slightly worse.

Then test rather than assume the conversion gap. It is measurable by running both and comparing, and the size of the difference decides whether the data is worth what it costs.

Social commerce and where the margin has to come from

Social channels create demand rather than capture it, which means acquisition is advertising rather than search, and advertising cost is the dominant line in the model regardless of the platform fee.

A product sold this way needs enough gross margin to fund content, paid distribution and a return rate elevated by impulse purchasing. Products with 45% gross margins that work on search-driven channels routinely fail here.

The fee is therefore close to irrelevant to whether the channel works. What decides it is whether the product has the margin to fund demand creation, and whether it demonstrates well enough in the format to make that demand creation efficient.

Attribution between social discovery and eventual purchase is genuinely difficult, since a customer may see a product several times over weeks before buying through a search.

That makes last-click measurement systematically unfair to social channels, and sellers who judge them purely on directly attributed sales usually undercount their contribution substantially.

Whichever checkout route is used, the product tag has to lead somewhere that converts on a phone. A tagged product linking to a slow or awkward mobile page wastes the entire content investment, and mobile page speed is the single most consequential technical factor in the channel.
