Rillet and Abacum Partner to Transform Financial Planning for Modern Finance Teams

Rillet has partnered with Abacum, a modern Financial Planning and Analysis (FP&A) platform, to help high-growth companies run faster and smarter planning processes. This integration brings together Rillet’s clean, real-time financial actuals with Abacum’s collaborative modeling tools - unlocking a more connected, accurate, and efficient approach to financial planning.

Automate, analyze, and plan with confidence

Integrating Abacum with Rillet enables a single source of truth for actuals, assumptions and long term strategy. This is a significant unlock for busy finance teams. 

By connecting Rillet’s subledger and reporting engine with Abacum’s forecasting workspace, teams can:

• Eliminate the export-import cycle: Automatically sync actuals from Rillet into Abacum without manual effort or CSV gymnastics
  

• Drill from plan to journal entry: Tie forecasts and variances directly back to transactions, vendors, and revenue drivers
  

• Model faster, with more accuracy: Build hiring plans, revenue scenarios, and expense forecasts using live actuals instead of stale snapshots

Together, Rillet and Abacum help finance and accounting teams work off the same data, with fewer surprises and faster insights.

Integration in action

This isn’t just a surface-level connection. The Rillet–Abacum integration was intentionally designed to streamline workflows for your teams:

• Automated headcount forecasting: Sync employee and payroll actuals from Rillet to power hiring plans and scenario models
  

• Granular cost analysis: Break down actual expenses by department, vendor, GL account, or custom dimensions from Rillet’s source data
  

• Variance tracking: Monitor forecast vs. actual in real time and investigate gaps with full context from Rillet’s audit trail
  

• Collaboration-ready planning: Abacum’s interface makes it easy to bring in budget owners, while Rillet’s roles and permissions ensure sensitive data stays secure
  

Real teams, real benefits

This joint solution is built for modern finance organizations that care about accuracy, speed, and clarity:

• FP&A teams can focus on strategic planning instead of spreadsheet maintenance
  
• Controllers and accountants trust that the numbers match the books, with clear auditability
  
• CFOs and execs make faster decisions with real-time visibility into metrics, forecasts, and runway
  

A new standard for finance stack integration

At Rillet, we believe the future of finance isn’t just about closing the books faster. It’s about intelligent systems that connect actuals to action. Abacum shares that belief, and this partnership represents a major step toward that future.
