Parties & birthdays

Plan the party. Skip the spreadsheet.

Cake, drinks, decorations, the surprise gift. The One Bill keeps the celebration simple and the math out of sight — so the only number you remember is the candle count.

No credit card required. Singing the birthday song remains a personal choice.

You probably know the drill. We just made the math part vanish.
