Stacks
AI-powered financial close and reconciliation platform
About Stacks
Stacks is a practice management platform designed for modern accounting firms, offering project management, time tracking, billing, and team collaboration tools in a clean, intuitive interface. The platform positions itself as the operational system that connects firm management to the accounting work happening across client engagements. Stacks' workflow features handle recurring engagement management — the platform tracks deadlines, manages task dependencies, and distributes work across team members based on capacity and expertise. The billing module integrates time tracking with invoicing, reducing the revenue leakage that occurs when billable time goes unrecorded or uninvoiced. For firms transitioning from spreadsheet-based operations, Stacks provides structured project management without the enterprise complexity of platforms like Karbon or Practice Engine. The platform is particularly well-suited to firms with 5 to 25 team members that need visibility into workload distribution and engagement profitability. Client management features track engagement history, key contacts, and recurring service schedules. The limitation is that Stacks focuses on practice operations and doesn't extend into the accounting work itself, requiring integration with separate tax, bookkeeping, and reporting tools.
