In Malaysia, there is a colloquial phrase in Manglish called "open order", which often used when a seller opens a list of slots for buyers to place in order to purchase the former's merchandises, most commonly home-made food or grocery items, which will be delivered directly to the buyers at a specific time slot.

Unlike the other type of online ordering activity where only the buyer and the seller have the knowledge of the order between them, in an "open order", the order is open for people to view and add their purchase requests to the list, although such people are commonly restricted to groups of people who know each other such as members of group messaging Whatsapp or Telegram. This "open order" activity, however, is not new and has been around for as long as I can remember in my teenage years (more than 20 years ago) when such a list was written on a piece of paper and passed around among my boarding school dormmates to purchase burgers for supper.

Searching online for "open order" returns results that touch on investment trading so I'm wondering if it is a misuse of that phrase to refer to the scenario that I elaborated above. If so, what would be the proper English term for it, if any?

N.B.: the order being open for other people to view the list of participants is a key characteristic of an "open order" where sellers specifically desire the publicity that comes from the participations. Potential buyers will also have, for the lack of better words, the "peer factor" from looking at the other buyers joining the list.

  • The system is called a "booking system" - this represents a system in which (dates and/or) times for goods or services are made available: The verb is "to book" -- "I've booked a meal to be delivered at 8:30. I would have booked an earlier time but they were fully booked until 8:30." / "Can you book tickets for the play?"

    @Greybeard, "booking system" does not relay the meaning of being "open", where everyone can see other people's bookings.

The term that I thought of (having never seen this feature before) was group order. And it seems to be the term that’s actually in use:

A group order allows multiple people to add their individual items into a collective order cart at the same time. Once a Group Order is created through your DoorDash Account, the rest of your group doesn’t need to have a DoorDash Account to use the group order link. — DoorDash

Two ways to Group Order

  • Group Order
    Administrators send out the restaurant choices, ordering link and manage the budget.
  • Open Group Order
    Employees order together with a group of coworkers and use Split with coworkers at checkout to share the cost.
