Use Cases
Built for the way you share.
Households, teams, co-owners, trips and everyone in between. If a group shares the cost, OneCard gives it one card and splits every purchase the moment it happens.
Every kind of group
If it's shared, it fits on one card.
Name the card for what it's for, invite whoever's in, and pick a split. Here are a few we'd start, and three we built around below.

For Roommates
One household. One card.
Rent, utilities, groceries, the router nobody wants to pay for. Everyone's share settles as it's spent.
- One card for the whole household: rent, utilities, groceries, cleaning supplies.
- Set percentage splits based on room size, income, or whatever the house agreed on.
- New roommate moves in? Add them to the card and adjust the split.

For Teams & Clubs
Fund the season, not the paperwork.
Rec leagues, booster clubs, team travel, office budgets. Set the rules, let the group spend inside them, and let every share land where it belongs.
- Cover league fees, jerseys, and tournament entries from one shared card.
- Give the club treasurer a card the whole board funds, with no personal account in the middle.
- Team travel: hotels, vans, and meals on a card with a ceiling you set.


Saratoga Syndicate 🐎
••••••••••••4821
04 / 28

For Shared Ownership
Every cost, already allocated.
Racing syndicates, fractional aircraft, boat partnerships. Costs land on the right owner in the right proportion, the moment they're incurred.
- A racing syndicate covering training fees, vet bills, farrier visits, and entries across owners.
- Fractional aircraft partners splitting hangar, maintenance, and fuel by share.
- A boat partnership handling slip fees, haul-outs, and insurance.

One card, your rules
Same card. Set up for your group.
Splits, roles, limits, merchant locks and expiry dates combine differently for every group. Here's how three of them might set it up.
