SageSync
Real-Time Inventory Synchronization Between ERP and CMMS
Tech Stack
Overview
SageSync keeps inventory data perfectly aligned between Sage 300 ERP and Fracttal CMMS, replacing manual reconciliation with automated, event-driven synchronization that achieves 99.9% data consistency.
The Problem
Inventory data lived in two disconnected systems: Sage 300 for financial tracking and Fracttal CMMS for maintenance operations. When stock was consumed for maintenance, the ERP didn't know. When purchases were recorded, the CMMS was out of sync.
The maintenance team made decisions based on stale data — ordering parts already in stock or discovering critical shortages too late. Manual reconciliation happened weekly, but errors accumulated faster than they could be fixed.
Without real-time visibility, the company couldn't accurately forecast inventory needs, leading to overstocking some items and stockouts of others.
The Solution
I built SageSync as an event-driven middleware service that listens for changes in both systems and propagates updates within seconds. OAuth2 token management handles secure API authentication with automatic refresh cycles.
The service includes intelligent conflict resolution — when both systems modify the same record within the sync window, business rules determine which change takes precedence. A comprehensive monitoring dashboard tracks sync latency, error rates, and system health.
Built-in retry logic and dead-letter queues ensure no data is lost even during temporary system outages, maintaining 99.5% uptime availability.
The Impact
Sync latency dropped from days to under 30 seconds. The maintenance team now works with real-time data, eliminating surprise stockouts and reducing emergency purchases.
Manual reconciliation effort decreased by 90%, freeing the operations team to focus on strategic inventory optimization instead of data entry.
What's Next
SageSync's next evolution targets a webhook-driven architecture — replacing the current polling-based synchronization with real-time event notifications from both Sage 300 and the e-commerce platform. This shift eliminates the polling interval delay and enables true sub-second sync latency for critical inventory and order data.
The observability roadmap includes containerizing the service with Docker Compose for consistent deployment, and adding a dedicated alert notification channel through email and Slack integration. When dead-letter queue items escalate beyond retry thresholds, operations teams will receive immediate alerts rather than discovering stale sync failures during manual reviews.
These improvements transform SageSync from a reliable batch-oriented bridge into a real-time integration backbone — positioning it to handle higher transaction volumes as the business scales its e-commerce operations.
