A REST API that replaces the manual Excel workflows FP&A teams run every month — budget management, actuals ingestion, and variance reporting in a single deployable binary.

The Problem

Every month, finance teams export actuals from their ERP, paste them into spreadsheets, and manually calculate budget vs. actual variances by department and GL account. It is slow, error-prone, and breaks the moment someone edits the wrong cell.

This engine moves that logic into a versioned, auditable API.
