Charlotte, NC – June 18, 2026 – Forest Systems, a leading provider of advanced general ledger accounting and reporting solutions for accounting firms, family offices, RIAs, and ultra-high-net-worth clients, today announced an API integration with BILL (NYSE: BILL), the intelligent finance platform trusted by nearly half a million businesses to manage, move, and maximize their money. Through this integration, accounting firms and wealth management organizations can now seamlessly automate accounts payable workflows between BILL and Forest Systems, helping them reduce manual work, improve operational visibility, and streamline financial operations.
“We are excited to partner with BILL to bring a more connected and automated financial operations experience to our clients,” said Ed Van Deman, CEO of Forest Systems. “Accounting firms, family offices, and sophisticated financial organizations require technology that can eliminate operational inefficiencies while maintaining accuracy and control. This integration aligns perfectly with our vision of delivering a modern, intelligent accounting ecosystem that allows firms to operate more efficiently and scale with confidence.”
As accounting firms, family offices, and wealth management organizations continue to grow in complexity, many still rely on disconnected systems and manual processes to manage payables, approvals, and financial reporting. These fragmented workflows can create inefficiencies, increase operational risk, and delay access to critical financial information.
The BILL API integration with Forest Systems addresses these challenges by directly connecting accounts payable automation with Forest’s comprehensive accounting and reporting platform. The integration creates a unified workflow that automates data synchronization, reduces duplicate entry, improves financial visibility, and accelerates operational processes across the organization.
“At BILL, innovation is driven by the real-world needs of the nearly half a million businesses we serve,” said Mike Cieri, Chief Product Officer at BILL. “As businesses grow, their financial systems must scale with them. We design our technology to connect seamlessly with the tools finance teams rely on every day. By integrating with Forest Systems through our API, we’re helping customers unify critical workflows so they can operate more efficiently and scale with confidence.”
