Bill.com

Leading cloud-based financial operations platform for SMBs, processing hundreds of billions in payment volume annually with a large network of connected businesses and accountants.

Bill.com (NYSE: BILL) is a leading cloud-based business payments and financial operations platform headquartered in San Jose, California. Founded in 2006, the company primarily serves small and medium-sized businesses by automating accounts payable, accounts receivable, expense management, and budgeting workflows. Its platform connects businesses with their suppliers, clients, accountants, and financial institutions to streamline the movement of money. Bill.com went public in December 2019 and has grown significantly through organic expansion and strategic acquisitions. Notable acquisitions include Divvy (expense management and corporate cards, acquired 2021 for ~$2.5B) and Invoice2go (mobile invoicing for freelancers and small businesses, acquired 2021 for ~$625M). These acquisitions broadened its platform from pure AP/AR automation into a more comprehensive spend management suite. While Bill.com is not a core AdTech company, it appears in the AdTech database due to lineage or ownership connections — possibly through Invoice2go or another acquired entity that had AdTech-adjacent functionality (such as small business marketing tools or digital advertising billing). Its primary market position is in FinTech/SMB financial operations, where it competes with Brex, Ramp, Tipalti, and others, processing hundreds of billions of dollars in payment volume annually.
