Airbase is built as a cloud-native spend management platform that integrates with ERP systems, HRIS tools, and corporate card networks to deliver end-to-end financial control. The platform supports multi-module deployments spanning accounts payable automation, corporate cards, expense reimbursements, and purchase orders — all governed by configurable approval workflows. As part of Paylocity's broader HCM platform, it connects HR data with financial operations, enabling real-time sync of employee records, cost centers, and budget allocations. APIs and native integrations allow finance engineering teams to embed Airbase data into their existing BI and accounting stacks.
