What is Airbase and how does it function? Airbase is a modern tool for managing expenses that automates AP accounting. It replaces the ad-hoc request process with pre-approved policies that are efficient and save time compared to other similar software. It also helps detect duplicate requests made by employees and allows for easy retrieval of contracts and invoices during approval. Unlike other applications where approval requires opening the app, Airbase allows approval via email without logging into the Airbase account. The software consolidates all payment methods, including virtual cards, physical cards, and ACH transfers/checks, automatically logging transactions into the database. Additionally, it offers separate cards for each vendor, reducing the risk of fraud and unauthorized auto-renewal. In addition to its in-app features, Airbase provides a strong support team to assist with any inquiries.
