Use network infrastructure instead of bookkeeping software when the missing capability is communication between endpoints and services. Infrastructure supplies access links, switching, addressing, routes, naming, traffic controls, monitoring, and resilient paths. Bookkeeping software supplies financial capture, coding, matching, reconciliation, and record retention.
They commonly coexist, especially when bookkeeping is hosted, but one cannot repair the other. A port, VLAN, address, route, resolver, policy, capacity, or path fault calls for network work. A missing receipt, wrong account, duplicate entry, unmatched payment, or close discrepancy calls for bookkeeping controls. This distinction also determines how source transaction and financial archive should be evidenced and reconciled.
