Bronze Wedding Anniversary Invitations: 20 Guests, €29.99

Twenty people are coming to dinner for your bronze wedding anniversary. You booked the restaurant back in March, counted the chairs twice, and then your brother calls: his two kids are coming after all, and could his in-laws come too. Nobody rings the kitchen to update the headcount. The restaurant serves more plates and adds them to the bill.

So the dinner moves every time the guest list moves. Your invitation doesn't. It's the one line in the budget that costs the same whether eighteen people sit down or twenty-two, and you pay it once.

A bronze wedding anniversary dinner is priced per cover, not per table

Restaurants charge per person. Twenty confirmations mean twenty portions, twenty glasses and twenty slices of cake. One bigger cake, two extra chairs, one more bottle: every late yes moves the whole bill. Confirming a place isn't a social detail you sort out later — it's the number the whole evening is built on, from the size of the table to the number of candles.

• Covers: 20 portions, 20 glasses, 20 chairs. You pay per head, not per table.
• Cake: ordered by the number of diners, so every late yes makes it bigger.
• The room: a dinner at home grows tables, tablecloths and someone pouring drinks.
• Digital invitation: €29.99 paid once, with no envelopes, stamps or reprints.

A group message to twenty people isn't free either

A message in the group chat doesn't tell you who's actually coming. Someone still has to read the yeses, write them down somewhere else, and chase the people who never replied. When the time or the restaurant changes, the message goes out a second time and you check again who read it. That's time, not money, and it still lands on somebody's evening.

Guests don't install anything. They open the link on a phone, look at the photos, hear the music and confirm from there. The invitation is a web page, not a PDF, so there's nothing to download and nothing to print. If someone in the family wants something to keep, do both: one link for everyone, a few printed copies for whoever will file them away. The printed version stays as it was printed. The link is the one that's correct tonight.

The dinner is billed per head. The invitation is billed once.

€29.99 across 20 guests, and the RSVP closes the list

Split €29.99 between twenty people and it comes to under €1.50 each. There's no subscription and no fee for each extra guest who joins the dinner. The confirmations arrive inside the invitation, in one list you can read in a minute, with the questions you set yourself. Close that list before you call the restaurant: the real number is what decides the size of the cake and how many tables to set. Start with the invitation — edit the cover for free, publish it with a link when it looks like your evening, and keep editing it afterwards if the plans change.
