LinkWorks — Enterprise System Integration for Corrigan Industrial

Connected a manufacturer's ERP, CRM, and warehouse management systems that had run in complete isolation for a decade — eliminating over 20 hours a week of manual data re-entry.

Project Overview

About This Project

Corrigan Industrial had run SAP for finance and production, Salesforce for sales, and a standalone warehouse management system for a decade — with zero integration between them. Every order required staff to manually re-key the same customer and order data into three separate systems, a process that consumed over 20 hours of staff time every week and was a constant source of costly data entry errors.

Digivance designed and built a middleware integration layer connecting SAP, Salesforce, and the warehouse system through a combination of REST APIs and event-driven messaging. Orders now flow automatically from sales through fulfilment without a single manual re-entry step, and all three systems stay in sync in near real time.

The Problem

Challenges We Solved

Triple Manual Data Entry

Every single order required staff to manually re-enter the same customer and order details into SAP, Salesforce, and the warehouse system separately — a process that ate over 20 hours of staff time weekly.

Frequent Data Entry Errors

Manual re-keying inevitably introduced mismatches between systems — wrong quantities, mismatched customer records, and pricing discrepancies that caused fulfilment delays and customer complaints.

No Real-Time Order Visibility

Sales had no visibility into actual production or inventory status in SAP, and warehouse staff had no visibility into new orders until someone manually keyed them in, often a day or more later.

Fragmented Customer Records

Customer information existed as three separate, frequently inconsistent records across the three systems, with no reliable single source of truth for account history or contact details.

Legacy Systems With Limited API Support

SAP and the warehouse system's older versions had limited and inconsistently documented integration capabilities, requiring careful custom integration work rather than an off-the-shelf connector.

Growing Order Volume Outpacing Manual Process

As order volume grew, the manual re-entry process became an increasingly severe bottleneck, with staff unable to keep pace during peak periods without significant overtime.

Our Approach

How We Solved It

Systems Landscape Mapping

We mapped the complete data flow across SAP, Salesforce, and the warehouse system to understand exactly what data needed to move where, and identified where inconsistent data models needed translation.

Middleware Integration Layer

Built a dedicated middleware layer to bridge the three systems' differing data formats and protocols, avoiding fragile point-to-point connections that would become unmanageable as more systems are added later.

Event-Driven Order Flow

Implemented event-driven messaging so a new order in Salesforce automatically triggers the corresponding SAP production record and warehouse fulfilment task — no manual step required anywhere in the chain.

Custom API Adapters for Legacy Systems

Built custom adapters to work around SAP and the warehouse system's limited native integration capabilities, ensuring reliable data exchange despite the age of the underlying platforms.

Data Validation & Error Handling

Every integration point includes explicit validation and error handling, with automatic alerting when data doesn't match expected formats — catching issues immediately instead of days later during reconciliation.

Parallel-Run Validation Before Cutover

Ran the new integrated flow in parallel with the manual process for three weeks, comparing outputs to validate accuracy before fully retiring the manual re-entry workflow.

Results

The Outcomes

Month 2 — Architecture & First Connection
Salesforce-to-SAP Integration Live

Middleware architecture designed and the first integration point — Salesforce to SAP order flow — went live, immediately eliminating the highest-volume manual re-entry step.

Month 4 — Full Three-Way Integration
Warehouse System Connected, Parallel Validation

Warehouse management system integration completed, connecting all three core systems. Three-week parallel-run validation confirmed data accuracy before full cutover.

Month 5 — Steady State
20+ Hours Weekly Reclaimed, 99.5% Reliability

Manual data entry process fully retired. Staff previously dedicated to re-keying data reassigned to higher-value work. Integration has maintained 99.5% reliability with zero order data mismatches since launch.

20+ Hours a Week Reclaimed. Zero Manual Re-Entry.
LinkWorks connected a decade of disconnected systems at Corrigan Industrial, turning three manual data entry points into one automated, reliable flow.
★★★★★
"We'd lived with triple data entry for so long we'd stopped thinking of it as a problem — it was just how things worked. Digivance showed us it didn't have to be that way. Orders now flow from a sales call straight through to the warehouse floor without anyone touching a keyboard in between, and our error rate has essentially disappeared."
