BILL (Bill.com)
Bank / A2A PaymentsBILL, still widely known as Bill.com, is the largest US accounts-payable and accounts-receivable payments platform for small and mid-sized businesses: 479,300 businesses, $98 billion of payment volume in the quarter to June 2026 and $1.65 billion of annual revenue, run from San Jose by founder René Lacerte since 2006 and listed on the NYSE since 2019. It charges per user — $49, $65 or $89 a month on the Essentials, Team and Corporate plans, custom for Enterprise — plus per-payment fees that it publishes in full: 59¢ per ACH, $1.99 per mailed cheque, free virtual-card and foreign-currency wires, 2.9% to pay or be paid by card, and 1% (minimum $9.99, maximum $100) to send money instantly. Its Spend & Expense card product, the former Divvy, is free. Licensed as a money transmitter in all 50 states, it is a serious, regulated piece of infrastructure; it is also a subscription business with a complicated fee table, uneven support and a stream of complaints about payments held in transit.
