Workflow Automation Suite for Manufacturing Pro
How we built a custom workflow automation system that reduced manual processing time by 60% and eliminated costly human errors in a manufacturing company.
Project Overview
A growing manufacturing company was drowning in repetitive manual tasks — order processing, inventory updates, invoice generation, and cross-system data entry consumed over 30 hours per week of staff time. We developed a comprehensive workflow automation suite that integrated with their existing ERP, CRM, and accounting systems to automate end-to-end business processes.
The Challenge
Manual Repetitive Processes
Staff spent hours each day copying data between systems, creating invoices, updating inventory, and processing customer orders manually.
Human Errors
Manual data entry led to frequent errors in orders, invoices, and inventory records, causing customer complaints and financial losses.
Disconnected Systems
ERP, CRM, e-commerce platform, and accounting software didn't communicate, requiring manual synchronization across all platforms.
Slow Response Times
Processing delays meant slower order fulfillment and poor customer experience, impacting competitiveness.
Our Solution
Custom Workflow Engine
We built a centralized workflow automation engine using Node.js and Express that orchestrates complex business processes across multiple systems with intelligent routing and error handling.
- Visual workflow builder for non-technical users
- Trigger-based automation (time, event, condition-based)
- Parallel processing for high-volume operations
- Comprehensive logging and audit trails
API Integration Layer
Developed custom API connectors and middleware to integrate ERP (SAP), CRM (Salesforce), e-commerce (Shopify), and accounting systems (QuickBooks) into a unified ecosystem.
- RESTful API integrations with all major systems
- Webhook listeners for real-time event processing
- Data transformation and validation layer
- Retry logic and failover mechanisms
Automated Document Generation
Implemented automated generation of invoices, purchase orders, packing slips, and shipping labels with customizable templates and PDF export.
- Template-based document generation
- Automatic email delivery to customers and vendors
- Cloud storage integration (AWS S3)
- Digital signature capabilities
Smart Notifications System
Created an intelligent notification system that alerts team members at critical workflow stages and escalates issues automatically.
- Multi-channel notifications (email, SMS, Slack)
- Role-based alert routing
- Escalation workflows for unresolved issues
- Custom notification templates
