Most domain marketplaces are built around negotiation. You list a price, buyers counter, and eventually you land somewhere in the middle — assuming the domain doesn't expire first.
NotRenewing skips that entirely. Every listing on the platform is priced at exactly $99, full stop. No offers, no back-and-forth, no auction countdown clock stacked on top of the renewal countdown clock that got the domain listed in the first place.
The logic is about matching the format to the moment. An expiring domain is, by definition, time-constrained inventory. Sellers who list there aren't trying to maximize a single sale — they're trying to avoid losing the asset entirely. A flat price turns a multi-day negotiation into a single decision a buyer can make in the time it takes to read the listing.
It won't replace negotiated marketplaces for premium, one-of-a-kind names — a flat $99 makes no sense for a domain worth six figures. But for the long tail of decent, ordinary, about-to-lapse names, removing the negotiation step entirely might be the more honest model: the domain is worth what it's worth to whoever's fastest to click buy, not what a seller wishes it was worth with three more weeks to shop it around.
