Four roles,
two pairings, one app.
Hubcux has two kinds of buyer and two kinds of seller. Which role you're in decides how you do things — but all four work in the same app, with the same payment protection.
Who meets whom
There are two separate flows and the roles never mix. But payment, order tracking and invoicing end in the same place for both.
Negotiation happens once, at the start of the period. The member orders, the supplier delivers. Prices aren't renegotiated on every order.
Requests accumulate through the day and close at 17:00. Quote requests go out at 17:15; buyer identities stay private and rival prices are never revealed before closing.
All four roles meet in the same place
Whichever flow it goes through, every order uses the same payment and document rails.
Which role are you in?
If you're buying, the type of need picks the path — and you can use both at once. If you're selling, contracted supply and pool bidding run side by side.
