One person organizes it, everyone chips in by card from a link, and the total is visible to the group. A group baby shower gift, one big item or cash for the parents, comes together on a clean record instead of a cash envelope.
Baby showers are the classic case for chipping in together: instead of twelve people buying twelve small things, the group covers the stroller, the crib, or a stack of cash the new parents actually need. The catch is collecting for it, one host ends up taking Venmo from some, cash from others, and reminding the rest while planning the whole shower.
Set the price of the item as the table's goal so everyone can see the number the group is aiming for, and let people chip in what works for them toward it. Some will cover more, some less, and the running total tells the host the moment there's enough to buy without anyone being singled out for an amount.
If the parents would rather have cash than a chosen item, the same table works: collect into it, and the host hands over exactly what the record shows. The money goes directly to the host through Stripe, TableCash never holds it, and the app is the record everyone who gave can open. Doing the shower with coworkers?
