Birthday party invitations you send as a link

Most birthday plans come apart on the headcount, not the theme. You book a table for twelve, nine turn up, and you pay for three empty chairs. An invite that states the time, the place and the food plan in its first three lines prevents a lot of that.

Bringalong builds you an event page in about a minute, with no account and nothing for guests to install. You get a public link to paste into the group chat you already use, plus a private manage link that stays with you. Guests tap Going, Maybe or Can't go, add a +1, and your count updates as they do.

How far ahead to send a birthday invite

Three weeks suits an adult party at home. That is long enough for people to move a Saturday around and short enough that they remember it. Push to four or five weeks if guests need flights, hotels or a sitter, and expect a second wave of replies after the first weekend passes.

Casual plans survive a shorter runway. Drinks on a Thursday can go out ten days ahead. A group dinner with a deposit should go out a month ahead, because the restaurant wants your number before your friends give it to you.

• Drinks or a bar meet-up: 10 to 14 days.
• Party at home, 15 to 30 guests: 3 weeks.
• Restaurant dinner with a deposit: 4 weeks, with a reply date 10 days before.
• Anything on a holiday weekend: 6 weeks.
• Guests flying in: 8 weeks, then a reminder at 2 weeks.

What the invite has to say

Guests scan an invite in about five seconds and decide two things: can I come, and what is this going to cost me. Answer both high up. A start time with no finish makes people guess, and the guess tends to land in the direction that leaves you cleaning at 2 a.m.

Keep the practical details in a block at the bottom so nobody has to text you about parking.

• Day name with the date: Saturday, March 14, not 3/14.
• Start time and a rough finish: 7 p.m. until about 11.
• Full address, plus the door code or which buzzer.
• The plan in one line: pizza at 8, cake at 9.30, music after.
• What to bring, or that there is nothing to bring.
• A dress note if it matters, including shoes-off houses.
• A phone number for the lost and the late.

Getting a real headcount

Assume a quarter of your guests go quiet on the first ask. That is a half-read message in a busy chat, not rudeness. Two nudges clear most of it: one a week after you send, one three days before the reply date, both aimed only at the people who have said nothing.

Tie the deadline to something real. "Let me know by Sunday so I can order the food" gets answers. "Let me know when you can" does not. Your Bringalong manage link puts the Going, Maybe and Can't go counts next to each other, so you can see who is still silent and message those people alone. There is a CSV export if you are handing numbers to a caterer or a venue.

Treat Maybe replies as half a guest for food and a whole guest for seating. Three Maybes in a group of twenty will not break your shopping list, but three missing chairs are obvious.

How much food and drink to buy

Catering math is where birthdays go over budget. For a two-hour drinks party, count six to eight bites per guest and assume anything hot gets eaten twice. For a sit-down meal, cook for your headcount plus one and make the sides generous rather than adding another main.

Guests get through about one and a half drinks in the first hour, then one an hour after that. Twenty people from 8 p.m. to midnight lands near 90 drinks, which is less alarming once you count the two friends nursing a single beer all night.

• Two-hour drinks: 6 to 8 bites per guest, half of them cold and made ahead.
• Wine: a bottle pours 5 glasses, so buy one bottle per two guests for three hours.
• Spirits: a 750 ml bottle makes about 16 drinks.
• Soft drinks and water: a liter per guest, more in summer.
• Ice: a pound per guest if you are chilling bottles in tubs.
• Cake: a slice each plus 15 percent, and a few boxes for people to take home.

Gifts, bar money and the bill

If you do not want presents, say so on the invite and give the impulse somewhere to go. "No gifts, bring a bottle if you are passing a shop" works. So does naming a charity you are collecting for. A bare "no gifts" still produces a pile of them, so clear a side table and accept it.

At a bar or a restaurant, name the money arrangement in writing. "Drinks are on me until 9, cash bar after" beats silence, and nobody ends up hovering near the till doing arithmetic. For a split bill, give the figure: about $45 a head including tip, cash or transfer on the night.

For a group present, ask someone who is not you to collect. Set a per-person amount, keep it low enough that it is an easy yes, and let people opt out by messaging the collector directly instead of in front of the group.

Where to send the link

An invite travels best in the app your guests already read. Paste the Bringalong link into the group chat, send it one-to-one to the two or three people who ignore group chats, and print the QR code for the fridge if a chunk of your guest list is family who prefer paper. Bringalong does not email or text anyone on your behalf, so the invite arrives under your name.

From the invite page a guest can drop the date into their own calendar as an .ics file or straight into Google or Outlook. That single tap kills most of the "wait, was it Saturday?" messages the night before. If the plan changes, edit the event from your manage link and the same link shows the new details.
