Planning made easy, so you can party like there’s no tomorrow!! Invites, RSVPs and payments for Hong Kong parties.

Plan somethingHow it works →

Free. Your guests never need an app or an account.

Party plan with Hong Kong efficiency.

  1. Choosing an invite look: Golden Hour, Golf, Scrapbook and Neon 開 themes

    Create your invitation

    Pick a look or upload your own art, then add the when and where. It takes about a minute.

  2. Invite extras: hosts, and privacy settings such as RSVP to see the address

    Customize your invite

    Make it yours: your wording, a dress code, a playlist, a bring list, cohosts. You decide who sees the address and the guest list.

  3. A hoi. invite for “Out of Office” at South Bay Beach with Going, Maybe and Can’t go buttonsThe same invite in the neon 開 theme

    RSVP in ten seconds

    Drop one link in the group chat. Guests tap Going, Maybe or Can’t go right on the invite. No app, no account.

  4. The host dashboard: 13 of 16 going, HK$4,400 collected, and “hoi. is reminding them, nothing to do”A guest’s First Class beach pass after paying

    All the payments, one place

    Everyone pays you straight by FPS or PayMe, and you see who’s paid at a glance. Paying gets guests a First Class boarding pass. Anyone who hasn’t gets friendly reminders from hoi., not from you, and nobody is ever called out. Splitting the bill after? Everyone settles up the morning after.

    We do the chasing. You do the partying.

Questions

Is hoi. free?

Yes. Making invites, collecting RSVPs and tracking payments is free for hosts and guests.

Do my guests need the app or an account?

No. They open your link from WhatsApp, tap Going and pay you. Nothing to download, nothing to sign up for.

How do payments work?

Guests pay you straight from their bank app by FPS or PayMe, then tap “I’ve already paid”. You confirm when it lands. hoi. never touches the money.

Who can see who’s paid?

Only you. Guests see how many people are going, never who has or hasn’t paid.

Who sees the address?

Everyone sees the area, like “Sai Kung pier”. Only guests who RSVP see the exact address.

Can I make an account with my phone number?

Not yet. For now we email you a link to make your account or log in. Phone numbers by SMS are coming soon.

Fai dee la! 開 your next party with hoi.
