#the-client

everything for the party, in one cart.

Party Depot sells everything for a celebration online: balloons, decorations, tableware, candles, costumes and toys, for birthdays, baby showers, weddings, graduations and every holiday in between. Shoppers browse by type, color, occasion, theme or age, and can put their own photo, name or initials on a balloon.

The brand wanted a store that feels as fun as the party, and that helps the many shoppers who know the occasion but not where to start.

#the-problem

a thousand items, zero party plan.

  1. 01Too much choice, no starting pointThousands of products across dozens of categories. Shoppers knew the occasion, not the product names.
  2. 02Custom items are hard to sell onlinePeople want their name or photo on a balloon, and they want to set it up without emailing back and forth.
  3. 03A stock theme looks like every other storeA default Shopify theme could not carry the brand's playful look or the browsing paths by color, theme and age.
#the-solution

describe the party. get the plan.

We designed the brand's interface and built a custom Shopify theme in Liquid, with menus by type, color, occasion and theme, Quick Add on every product card, and a homepage that changes with the season.

PlanTogethr AI lets shoppers enter the occasion, guest count, date and budget and get a party plan in seconds. It runs as an n8n workflow that calls a GPT model. Customily handles personalization, so shoppers pick a shape, size and color, upload a photo and add their own text right on the product page.
