The wallet types your organization can open, PayKeeper's fee on
disbursements from each, and whether each wallet gets an account number
of its own (fundingAccount). PayKeeper sets these up for your
organization. A
preset expands into the wallet's policy: who can see it, who can fund
it, who can disburse from it and who administers it. Name one when you
create a wallet.

FUNDING is the usual one: collected from the payers you give
instructions to, disbursed only on your instruction, with no PayKeeper
approval step. If none fits, ask PayKeeper.
