A payment network like GRAFT makes for a good solution for this use case with support for the company (merchant) tokens and private overlay networks while leveraging the robust features of the underlying POS-compatible permissionless blockchain network https://www.graft.network/2018/12/19/enterprise-perks-and-rewards-on-graft-blockchain/

GRAFT project follows the best industry practices in keeping both design and implementation completely transparent so anyone can examine and contribute to it. https://captainaltcoin.com/graft-publishes-request-for-comments-on-proof-of-stake-mechanism/

GRAFT network uses a unique technology called Real-Time Authorizations (RTA) which allows to process instant transaction authorizations and preauthorizations. More info about RTA and preauthorizations here (see sections 4 and 3 respectively) - https://www.graft.network/2018/11/20/how-graft-is-similar-to-and-at-the-same-time-different-from-visa-and-other-payment-card-networks-part-1/
