Airbase

Airbase is a leading platform in the rapidly growing category of modern "Spend Management." It represents a philosophical shift away from siloed financial tools. Historically, a mid-market company would use one software for Accounts Payable (like BILL), a completely different software for employee expense reports (like Expensify), and physical corporate credit cards from a traditional bank. Airbase collapses all three of these functions into a single, unified, software-defined platform, providing finance teams with absolute, real-time visibility and control over all non-payroll corporate spending. The foundation of Airbase is its deep integration with corporate card issuance. The platform allows finance teams to instantly generate virtual and physical corporate credit cards for employees. However, unlike traditional bank cards, Airbase cards are software-controlled. A manager can issue a virtual card specifically for an employee's AWS subscription, locking the card to that specific vendor and setting a hard monthly limit of $500. If AWS tries to charge $501, the software instantly declines the transaction, completely preventing budget overruns. Furthermore, the employee simply takes a photo of the receipt on their phone, and the transaction is automatically coded and synced to the general ledger. On the Accounts Payable side, Airbase offers a robust, modern bill pay system. It handles complex, multi-stage approval workflows for massive vendor invoices. What makes Airbase unique is its "Amortization" engine. If a company pays a massive $120,000 annual software subscription upfront, Airbase automatically understands the accounting principles and creates the journal entries to smoothly amortize that expense over 12 months in the general ledger (e.g., NetSuite). By unifying corporate cards, expense reimbursements, and massive vendor AP, Airbase is the platform of choice for hyper-growth technology companies and modern mid-market firms.
