# Place Order

> Place an order against another studio's swap offer.

Places an order against another studio's swap offer. The platform takes no commission: only the guaranteed-price escrow is held on each side.

Eligibility is checked at submit time:

* you own the model on your side
* model meets the performer-top floor
* OnlyFans session is active for the model
* model has at least 5 GG content items and at least 2 promo texts
* requested quantity falls inside the offer's `[min_quantity, max_quantity]`
