Every party order has a deadline printed on an invitation, which makes the delivery date the biggest conversion factor in this category. The shopper knows the theme, the date and roughly how many children are coming, and is trying to buy one of everything without ending up with plates for eight and cups for twelve. If your page cannot promise arrival before Saturday, the basket goes to a shop that can.
We write growth plans for kids' party supply stores that already sell online. The plan covers Shopping feeds that carry the theme and the pack count in the title, guest-count bundles that do the arithmetic for the shopper, delivery cutoffs shown before the basket is started rather than in the footer, licensing handled properly in ads and listings, and a reminder that lands eleven months later when the same birthday comes round again.
It also covers what can and cannot be shipped or advertised, which in a shop selling balloons is not a small question.
A party is bought in a single sitting, usually in the fortnight before the date, by a parent working from a theme and a headcount. The theme is decided by the child and is not up for negotiation. The headcount comes off the invitation list. Everything after that is arithmetic the shopper would rather not do: how many plates, cups, napkins, party bags, balloons and candles for that many children, plus a few spares for the adults standing at the back.
The store that does the arithmetic wins. A pack of eight in one product and sixteen in another across the same theme is how a basket ends up wrong, and a wrong basket on the morning of a party is a story that gets told to other parents.
Delivery is the second decision and often the first. The cutoff has to be visible before the shopper starts filling a basket, and the whole order has to arrive together, because a table missing its plates is not partly solved.
Personalised items, banners with a name and an age, need production time and cannot be returned, so both facts have to be obvious. Balloons carry their own rules, since helium cannot be shipped the way customers assume. The repeat is the most reliable in the industry: the same child has a birthday every year, and there is often a sibling.
