BILL is a financial operations platform for small and midsize businesses, headquartered in San Jose, California. The company serves approximately 500,000 businesses and 9,000 accounting firms, with a proprietary network of over 8 million members. BILL's total payment volume represents approximately 1% of U.S. GDP, and fiscal year 2025 revenue was nearly $1.5 billion.
BILL's core offering is an AI-enabled platform that automates accounts payable (AP), accounts receivable (AR), expense management, and B2B payments. Businesses use BILL to generate and process invoices, streamline multi-level approvals, make and receive payments (ACH, check, card, international wire), manage employee expenses via BILL Spend & Expense (corporate cards with budget controls), and sync everything to their accounting system. BILL integrates deeply with popular accounting software, banks, card issuers, and payment processors.
Businesses use BILL to digitize and accelerate their payables and receivables workflows — particularly SMBs that rely on their accountant or bookkeeper and need a platform that connects seamlessly to QuickBooks, Xero, Sage, or NetSuite. BILL is a common choice for small and midsize businesses that want to move off manual check-cutting and paper invoicing, gain approval workflow controls, and centralize AP/AR and spend management without building an enterprise-grade finance stack.
