Abstract: A purchase management system includes a central database arrangement, a customer interface to the central database arrangement, and a bank specific database module, arranged to communicate with a transaction authorization module within a bank. The central database arrangement is arranged to receive, from a purchasing entity through the customer interface, purchasing rules applying to a purchasing group, and includes central processing means arranged to: add a selected purchasing group as metadata linked to a first transaction ID in the central database arrangement; add the purchasing rules applying to said purchasing group as metadata linked to the first transaction ID in the central database arrangement; and transfer metadata linked to the first transaction ID to the bank specific database module.

Abstract: A purchase management system 100 comprises a central database arrangement 110 and a purchasing authorization database module 130, arranged to communicate with a transaction authorization module 405. The central database arrangement 110: receives, from a purchasing entity 200, purchasing rules applying to a purchasing group 250; adds a selected purchasing group 250 as metadata linked to a first transaction ID; adds the purchasing rules applying to said purchasing group 250; and transfers the metadata to the purchasing authorization database module 130. The purchasing authorization database module 130 receives a purchase approval request from the transaction authorization module 405; decides on the purchase approval request based on whether the requested purchase fulfils the purchasing rules; responds to the transaction authorization module 405 with approval or rejection of the purchase approval request; and transfers the transaction information to the central database arrangement 110.
