In an example embodiment, a group of local trusted devices is formed based, at least in part, on locations of a plurality of devices. Then a payment tree is presented in a user interface of a first device in the group of local trusted devices, the payment tree including a graphical representation of relationships between devices in the group and permitting selection, by a user of the first device, of one or more devices in the group to share in paying a bill received from a device outside the group. A bill may then be generated from the first device to each selected device in the payment tree, the bill indicating a payment amount reflecting a portion of the bill received from the device outside the group. |
