Pig Roast RSVP Website: Portions, Table Seats, and a Meat Order
A pig roast RSVP has to lock portions and table seats before the meat is ordered, because a whole roast is sized to a headcount and a maybe cannot be fed from a pig that was already bought.

A pig roast goes wrong when the animal is ordered for a guess and the yard fills with people who never said they were eating. A whole roast is bought against a headcount the pit master or the caterer asked you for. A maybe cannot be fed from a pig that is already on the fire, and a vegetarian who arrives to "just have sides" still needs a plate, a chair, and a serving that you did not steal from someone else's pork. Tables, shade, and trash all have a size. The roast does not expand because the afternoon feels festive.
You can create a pig roast RSVP that separates people who will eat pork from people who will only eat sides, and stops when the order and the tables are full.
Get the portion number from the person cooking, then cap to it
Ask the caterer, the butcher, or the friend running the pit what headcount the roast you are buying is meant to feed, and what time they need that number locked. Write their answer on your planning sheet. Do not publish a pounds-per-person figure you made up, and do not let the invite promise "plenty for whoever shows up." If they count children as partial portions, ask how they want children marked and use that same split on the form.
Set a capacity limit on people who will be on the property, and a second count in your own notes for pork eaters versus sides only. The form can stop new yeses when the yard, the table seats, or the pork portions are gone. Say which limit closed. If the pit can feed forty and you only own tables for twenty-four, twenty-four is the party unless you rent more tables before you raise the cap.
Ask each person, or one adult per household, to pick a food line:
Eating pork and sides counts against the roast order and the table
Sides only counts against the side dishes and the table, not against the pig
Not eating still counts against chairs and parking if they are coming
A household reply keeps one parent from saying yes while another family member sends a separate maybe for the same seats.
Allergies, smoke, and the rest of the menu
Pork is not a neutral menu. Ask about a pork avoidance, a severe allergy, and anything in the sides that can hurt someone: nuts in a salad, gluten in a bun, shellfish if you added a second pot. Use a severity field so "I do not love pork" is not stored the same way as an allergy that cannot share a cutting board. Tell guests whether the vegetarian sides are cooked apart from the pig or on the same table. If everything sits in the smoke, say that too. People who cannot be around that smoke need to know before they drive over.
Write what you are actually serving besides the roast, in plain food names. If guests may bring a side, cap those offers. Five pasta salads and no water is a planning failure. If you are not taking extra dishes, say the meal is provided and ask people not to add a surprise tray that you have no table for.
Shade, seats, and the carve time
List the start time, the time you expect to carve, and the time you need the yard clear. A roast that is ready at four does not wait until six because a group chat is running late. Late plates dry out, and the people who arrived on time should not lose their serving to people who did not reply. Ask for a phone number so you can release a no-show portion before you wrap the meat.
If the roast is outside, say where people sit if it rains: a tent you have already rented, a porch that holds a number you counted, or a postpone. "We will squeeze inside" only works if you counted the inside chairs. Name the parking rule if you are in a neighborhood that will complain about a street full of cars.
Lock the order on the caterer's clock
Close the RSVP on or before the moment the meat order cannot change. After that, a late yes gets sides only if you truly have extra, and only if you still have a chair. Do not tell them to "just come" and then short the people who replied. Export the list the day you order and again the morning of the roast: name, pork or sides only, allergy with severity, household, phone.
A pig roast RSVP is finished when the number you gave the pit matches the pork eaters, every other guest fits a chair you own, and nobody is promised a plate that was never in the order.
