SageConnect
Automating ERP Integration for 200+ Enterprise Staff
Tech Stack
Overview
SageConnect bridges the gap between Sage 300 ERP and supplier portals, replacing error-prone manual workflows with a fully automated integration platform. Built for an enterprise with 200+ staff members across multiple departments, the system processes CFDIs, purchase orders, payments, and supplier data in real-time.
The Problem
The company relied on manual data entry between Sage 300 ERP and their supplier portal. Staff members had to copy invoice data, purchase orders, and payment information by hand — a process that was slow, error-prone, and unsustainable as the business grew.
With 200+ employees affected across procurement, accounting, and operations, even small errors cascaded into delayed payments, supplier disputes, and reconciliation nightmares. The accounting team spent hours each week fixing mismatched records.
The existing workflow couldn't scale. Every new supplier meant more manual touchpoints, more chances for human error, and more time spent on data entry instead of strategic work.
The Solution
I designed and built SageConnect as a dual-runtime system: a web dashboard for real-time monitoring and manual overrides, paired with a background processor that handles automated data synchronization around the clock.
The platform connects directly to Sage 300's database and the supplier portal's APIs, mapping data fields bidirectionally and validating every transaction before it's committed. Custom transformation rules handle edge cases in CFDI formatting, currency conversions, and tax calculations.
The system includes a monitoring dashboard that gives operations teams visibility into sync status, error rates, and processing queues — enabling them to catch and resolve issues before they impact business operations.
The Impact
Within the first month of deployment, manual data entry errors dropped by 95%. The accounting team reclaimed over 20 hours per week previously spent on reconciliation and error correction.
The platform now processes all supplier transactions automatically, achieving 100% synchronization coverage. Workflows that previously took days now complete in minutes, and the system scales effortlessly as new suppliers are onboarded.
What's Next
The current system relies on an external Windows executable (ImportaFacturasFocaltec.exe) to import CFDIs into Sage 300 — a black box with no structured error feedback, no per-invoice tracking, and no correlation between processed XMLs and created batches.
The next evolution replaces this executable entirely by integrating directly with Sage 300's REST Web API. This eliminates the dependency on Windows, enables granular error handling per invoice, and makes the entire data flow observable and testable from Node.js.
This migration also addresses critical reliability gaps: payments that upload to the portal before confirming CFDI import, silent failures in control table inserts, and XML corruption from race conditions in the addenda injection pipeline.
