Know who’scoming.

Your guests tell you on their own page whether they’re coming and what they’d like to eat. You see the answers come in, and the kitchen cooks for everyone who said yes.

Messages that send themselves

For each round you plan an invitation and reminders: when they go, to whom, and by email, WhatsApp or both. Name, date and deadline fill in for each guest.

  • Attendance, menu choice and a final check
  • Reminders only for those who haven’t replied
  • For each message you see who opened it
The messages per round: the invitation of 22 September, the reminder of 1 October and the menu-choice round.
A guest’s personal inbox: one message is waiting for you.

One page per guest

Every guest gets their own link. There they tell you whether they’re coming, what they’d like to eat and what the kitchen should watch out for. No app, no account.

  • Allergens with every dish
  • Bringing someone? They’re added in a moment
  • Still changeable until the deadline
Is this right? The guest’s details are already filled in.
The guest chooses their dishes, with the allergens for every dish; the venison stew is chosen.

Cook for what was chosen

After the deadline you see how many of each dish were chosen. Your kitchen cooks for those numbers, not for a guess.

  • Allergies and requests by name

What does a no-⁠show guest cost?

Without RSVPs, your caterer cooks for everyone you invite. Work out what that costs, with your own numbers.

€4,320 a year on covers nobody eats. 96 covers: 12 crates· €1,080 per event

Ask for RSVPs first and you only order for the people who said yes.

How we calculate

Worked example. All four are your own numbers: how many events you run a year, how many people you invite, how many usually don’t come and what your caterer charges per cover.

How we work it out: without RSVPs your caterer cooks for everyone you invite. 4 events × 120 invitees × 20% who don’t come = 96 covers; × €45 = €4,320 a year.

One crate stands for 8 covers. Waste Warrior doesn’t weigh anything at your event: it lets you know in advance who’s coming and what they’ll choose.

Questions we
often hear.

No. Each guest gets a personal link by email or WhatsApp and simply opens their page in the browser.

You import a CSV file with name, email address and phone number, add guests by hand, or share a registration link. You can combine these routes.

At the moments you schedule. For each phase you set up an invitation and reminders, each with its own time, audience and channel. Nothing is sent until the event is published.

Yes, if you allow it. The guest adds the people coming along on their own page and gives a menu choice for them too.

You set the allergens for each dish in the menu, so guests see them before they choose. Whatever guests note themselves, you read back for each guest.

Yes. We start with a pilot and only expand after we evaluate it together.

Does your sum add up?

You worked it out above. In a demo we show you how an event runs, from guest list to menu choice. Then you start small, with a pilot at your next event.
