SAN FRANCISCO, September 30, 2025 — Karbon, the global leader in practice management software for accounting, bookkeeping, tax and audit firms, today announced its acquisition of Aider, a pioneer in AI-powered advisory and reporting technology. The acquisition accelerates Karbon’s vision to transform the accounting profession through AI.

Aider’s cutting-edge solution is already trusted by firms across the United States, Canada, Australia, and New Zealand for automating time-consuming bookkeeping and advisory workflows like reconciliations and period close, while delivering real-time client insights and predictive reporting. By integrating Aider’s capabilities into Karbon, firms will gain powerful tools to eliminate repetitive work, expand advisory services, increase profitability, and automate period close.

“This is a defining moment for the future of accounting practice management,” said Mary Delaney, CEO of Karbon. “With Aider, we’re accelerating the shift from administration to automation—giving firms the ability to automate the mundane, scale without added overhead, and deliver richer advice to their clients.”

“Aider is incredibly proud to join Karbon,” said Brendan Roberts, CEO and Founder of Aider. “We share a bold vision for the future where accounting is proactive, data-driven, and deeply client-centric. Karbon is the ideal partner to scale that vision and deliver even more value to our customers.”

The acquisition will deepen the recently launched integration between the two platforms, with an AI-powered period close experience built directly into Karbon’s practice management platform. This brings firms closer to intelligent, automated operations where repeatable workflows don’t just get tracked, they get completed with confidence.

With Aider integrated into Karbon, firms will benefit from:

• Automated period close with task coordination, follow-up and inline editing of uncategorized transactions with the most popular general ledgers

• AI-generated management reports featuring real-time insights, KPIs, and executive commentary
