Event RSVP and Guest Management Glossary
Plain definitions of the terms hosts, planners, and caterers use when collecting replies and counting plates, followed by answers to the questions we hear most often.
- Allergen
- An ingredient that can trigger an allergic reaction in a guest, such as peanuts, tree nuts, shellfish, dairy, eggs, wheat, or soy. Allergens are recorded as dietary restrictions attached to a named guest so the kitchen can act on them.
- Attendance status
- The current answer for a guest or household: attending, declined, no reply, or partial reply. Keeping a status per household is what makes reminders and headcounts possible without rereading every message.
- Catering buffer
- A small number of extra plates ordered above the confirmed count to cover late changes, unexpected guests, and meal swaps. Caterers often build their own overage into prep, so agree on who is responsible for the buffer.
- Change log
- A dated record of every edit to the guest list: who changed, what changed, and when. A change log lets a host trace a restriction or a headcount shift back to its source instead of re-asking the guest.
- Children's meal
- A separate, usually simpler and less expensive plate offered to young guests. Collecting a child flag or age with the RSVP lets the caterer count children's plates apart from adult plates.
- Confirmation message
- A short on-screen summary or email sent to a guest after they reply, restating their attendance, party names, meal choices, and restrictions. Confirmations catch mistakes while the guest still has the form open.
- Cutoff date
- The internal date after which the host stops accepting changes and treats silent guests as declined. It usually sits a few days before the caterer's guaranteed count deadline and later than the reply-by date printed on the invitation.
- Dietary restriction
- A constraint on what a guest can eat regardless of the menu, including allergies, intolerances, medical diets, religious requirements, and ethical choices such as vegan. Restrictions are collected separately from meal choices and attached to the individual.
- Guaranteed count
- The final number of guests, often broken down by meal option, that a host commits to the caterer by a contractual deadline. Many caterers bill on the guaranteed count or the actual attendance, whichever is higher.
- Guest list
- The master record of everyone invited to an event, typically organized by household with individual guests underneath. A well structured guest list is the single source of truth for invitations, replies, meals, seating, and the caterer's count.
- Household
- The unit that receives one invitation, such as a couple, a family, or a single guest with a plus one. Households carry the contact details and seat allowance; the individuals within them carry meals and restrictions.
- Invitation
- The message, mailed or digital, that asks a household to attend and tells them how to reply. For online collection, the invitation carries a reply link that identifies the household and its allowed seats.
- Meal choice
- A guest's selection from the menu options the host offers, such as chicken, fish, or a vegetarian entree. Meal choices are collected per named guest so the caterer receives a plate count for each option.
- One of the entrees or plates a guest can choose. Writing menu options in plain, appetizing language and noting whether each is vegetarian, vegan, gluten-free, or nut-free reduces unclear dietary notes.
- No-show rate
- The share of guests who confirmed attendance but did not arrive. It varies widely by event type, and the best guide for planning a buffer is your own past events rather than a general figure.
- Partial reply
- A household that has answered some questions but not all, most often confirming attendance without choosing meals or naming a plus one. Partial replies need a targeted follow up rather than a generic reminder.
- Place card
- A small card at each seat showing the guest's name, and often a discreet marker indicating their meal choice so servers deliver the correct plate. Place cards are generated from the final guest list and seating chart.
- Plate count
- The total number of meals to be served, usually broken down by menu option, children's plates, and vendor meals. The plate count is derived from attending guests and their meal choices, not maintained separately.
- Plus one
- An additional guest a named invitee is permitted to bring. Hosts decide in advance who receives a plus one, whether the plus one must be named, and whether they choose their own meal.
- Regrets
- A polite term for a declined invitation, as in "regrets only" on an invitation that asks guests to respond only if they cannot attend. Regrets-only invitations are risky when a caterer needs an accurate count.
- Reminder sequence
- A planned series of follow up messages sent to households that have not replied, usually one before the reply-by date, one on it, and a personal message afterward. Each reminder includes the reply link.
- Reply link
- A unique web address sent to each household that opens their RSVP form with their names and seat allowance already known. Reply links remove the need for accounts and let guests return later to make changes.
- Reply-by date
- The deadline printed on the invitation by which guests are asked to respond. It is set earlier than the caterer's deadline to leave time for reminders and changes.
- Response rate
- The share of invited households that have replied, whether yes or no. It depends heavily on how easy the reply process is and on the reminder sequence, and there is no universal figure to plan around.
- RSVP
- From the French phrase meaning "please respond", the request that guests confirm whether they will attend. In modern use it also covers collecting party size, meal choices, and dietary needs alongside the yes or no.
- Save the date
- An early notice sent before the formal invitation so guests can hold the day. Save the dates do not usually collect replies, though some hosts use them to gather addresses and contact details.
- Seating chart
- The assignment of attending guests to tables and seats. A seating chart built from the final guest list carries meal choices and restrictions to each table so servers and the kitchen can find them.
- Single source of truth
- The principle that one list holds every reply, meal, restriction, and change, and every count is derived from it. Keeping separate tallies in messages, notebooks, or a second spreadsheet is what causes counts to drift.
- Vendor meal
- A plate provided to working staff at the event such as photographers, musicians, and coordinators. Vendor meals are often required by contract and are easy to forget when sending the caterer a count.
- Walk-in
- A guest who attends without having replied or registered. Walk-ins are rare at weddings and common at open corporate or community events, so plan a policy and a buffer with the caterer.
Questions people ask
What does RSVP actually mean and do guests still need to do it?
RSVP comes from a French phrase meaning "please respond". Guests very much still need to do it, because the reply is what tells the host how many seats, plates, and place cards to prepare. The format has changed from mailed cards to links and forms, but the purpose is the same.
How long should guests have to reply to an invitation?
Enough time to check their calendar and coordinate with a partner, but not so long that the invitation gets buried. For weddings, invitations commonly go out six to eight weeks ahead with a reply-by date three to four weeks before the event. For smaller events, two to three weeks to reply is usually plenty.
Is it rude to ask guests for meal choices on the invitation?
No, it is expected, and most guests appreciate knowing what will be served. What guests find tiresome is being asked twice, so collect the meal choice and any dietary restrictions in the same form as the attendance answer whenever the menu is set.
What is the difference between a dietary restriction and a meal preference?
A meal preference is a choice from your menu: the guest would rather have fish than chicken. A dietary restriction is a constraint the kitchen must respect no matter what, such as an allergy, a medical diet, or a religious requirement. Ask them as separate questions so restrictions are never buried in a menu pick.
How do I handle a guest who RSVPs for more people than were invited?
The best fix is prevention: a form that only allows the number of seats the household was given. If it happens anyway, a short, warm message explaining that space is limited and the invitation was for the named guests resolves most cases. Decide your policy before invitations go out so you are not deciding under pressure.
When does the caterer need the final headcount?
It varies by caterer and menu, typically somewhere between a few days and two weeks before the event, so ask for the exact date when you sign the contract. Set your own reply-by date and internal cutoff earlier than that so you have time to chase silent guests and record late changes.
How many extra meals should I order?
There is no universal number. Ask your caterer what overage they already build into prep, then consider a small buffer of your own based on how many late changes and unexpected guests your past events produced. Remember to count vendor meals separately since they are usually required by contract.
Should I use paper reply cards or an online RSVP?
Online replies are easier for most guests, produce cleaner meal and restriction data, and let guests update their own answers. Paper cards remain a nice courtesy for guests who will not use a link. If you offer both, enter every paper reply into the same online list so there is one source of truth.
What is a typical RSVP response rate?
It varies so much by event type, guest relationship, and reply method that no single figure is useful. What is consistent is that response rates rise when the reply takes under two minutes on a phone and when reminders go out on a planned schedule. Track your own rate per event and use it for future planning.
How do I collect RSVPs for a corporate event?
The same way as any event, with a few adjustments: send a single reply link through the channels your organization actually uses, avoid requiring accounts, let people register on behalf of a colleague where that is normal, and set a registration close date. Plan for walk-ins and no-shows based on your organization's past events.
Can guests change their RSVP after submitting?
They should be able to, because changes will happen whether or not you allow them formally. A reply link that reopens the guest's own form lets them update their party or meal directly, with the change recorded and dated. Lock the form only when you truly need to freeze the count.
How do I keep guest information private when sharing lists with vendors?
Share only what each vendor needs. The caterer needs counts per meal and a restriction list by name or table; the venue needs totals and the seating chart; the coordinator needs names and tables. Export a filtered view for each rather than sending the full spreadsheet with addresses and phone numbers.
What information should an RSVP form ask for?
At minimum: attendance, the number of people in the party, each person's name, each person's meal choice, and any dietary restrictions. Add event-specific questions such as transportation or accommodation only if you will act on the answers. Keep required fields to the essentials so the form stays short.
