Integrating Disparate HR Systems using Make.com: Mid-Atlantic Manufacturing’s Journey to Unified HR Data

In today’s fast-paced manufacturing environment, efficient operations extend beyond the production floor to every facet of the business, especially human resources. Yet, many mid-sized companies grapple with legacy HR systems that operate in silos, creating inefficiencies, data inconsistencies, and significant manual overhead. This case study details how 4Spot Consulting partnered with Mid-Atlantic Manufacturing Co., a leader in industrial components, to overcome these challenges by integrating their disparate ATS, HRIS, and payroll systems using Make.com, establishing a single source of truth for their critical HR data.

Client Overview

Mid-Atlantic Manufacturing Co. is a well-established, mid-sized industrial components manufacturer with a workforce of approximately 350 employees across three regional facilities. With a strong commitment to quality and innovation, the company had grown steadily over the past two decades. Their HR department, however, was struggling to keep pace with this growth dueed to an aging technology stack. They utilized a legacy Applicant Tracking System (ATS) for recruitment, a separate Human Resources Information System (HRIS) for employee records and benefits, and an entirely distinct payroll provider. Each system, while functional on its own, lacked seamless integration with the others, creating a fragmented data landscape.

Their HR team of eight professionals was spending an inordinate amount of time on data entry, reconciliation, and manual reporting. This not only diverted their focus from strategic HR initiatives but also introduced a significant risk of errors, particularly in critical areas like payroll and compliance. The company recognized that their HR systems were a bottleneck, hindering their ability to scale, make data-driven decisions, and provide a superior employee experience. They sought an expert partner to modernize their data infrastructure without a complete, costly rip-and-replace of their core systems.

The Challenge

Mid-Atlantic Manufacturing Co.’s HR operations were plagued by several critical challenges stemming from their disconnected systems:

• Data Silos and Inconsistency: Information about a single employee was fragmented across three separate platforms. A new hire’s data would be entered into the ATS, then manually re-entered into the HRIS upon offer acceptance, and finally input again into the payroll system. This repetitive data entry was a primary source of discrepancies.
• Excessive Manual Data Entry: The HR team estimated they spent nearly 30% of their time on manual data entry and cross-referencing information between systems. This was particularly acute during onboarding, offboarding, and benefits enrollment periods.
• High Risk of Human Error: Each manual data transfer presented an opportunity for error, leading to incorrect payroll deductions, benefits eligibility issues, and compliance risks. Rectifying these errors was time-consuming and often led to employee dissatisfaction.
• Lack of a Single Source of Truth: There was no centralized, real-time view of employee data. Generating comprehensive reports on headcount, turnover, or labor costs required laborious data extraction, merging, and reconciliation from multiple systems, often resulting in outdated or conflicting information.
• Delayed Onboarding Process: The manual transfer of new hire data from ATS to HRIS and payroll meant a sluggish onboarding experience. New employees often faced delays in gaining system access, receiving accurate paychecks, or enrolling in benefits, impacting their initial experience and productivity.
• Limited Scalability: The existing manual processes were unsustainable for future growth. Any increase in hiring volume would exponentially increase the HR team’s administrative burden, making it difficult to expand operations without proportional increases in HR staffing.
• Inefficient Reporting and Analytics: Strategic HR planning was hampered by the inability to quickly access accurate, consolidated data. Decision-making for workforce planning, talent management, and operational efficiency was therefore reactive rather than proactive.

Mid-Atlantic Manufacturing understood that these challenges were not just administrative burdens but strategic impediments. They needed a robust, flexible, and cost-effective solution to bridge these data gaps and create a streamlined, error-free HR data flow.

Our Solution

4Spot Consulting approached Mid-Atlantic Manufacturing’s predicament with our “OpsMesh” framework, focusing on strategic integration rather than wholesale replacement. Recognizing the client’s existing investments and the robust capabilities of Make.com as a powerful low-code automation platform, we proposed a comprehensive integration strategy. Our solution centered on using Make.com to serve as the central nervous system, orchestrating data flow between the legacy ATS, HRIS, and payroll systems.

The core components of our Make.com-powered solution included:

1. Discovery & OpsMap™ Audit: We began with a detailed OpsMap™ diagnostic to thoroughly map Mid-Atlantic Manufacturing’s existing HR workflows, identify all data points, system APIs, and pinpoint every manual touchpoint and potential error source. This forensic analysis provided a clear blueprint for the integration strategy.
2. Make.com as the Integration Hub: We leveraged Make.com’s extensive library of pre-built connectors and its flexible API capabilities to establish robust, bi-directional data pipelines between the client’s Greenhouse ATS, BambooHR HRIS, and ADP Payroll systems. Where direct connectors were unavailable, we utilized Make.com’s HTTP module to interact with custom APIs.
3. Automated New Hire Onboarding: A cornerstone of the solution was the automation of the new hire process. Once a candidate was marked as “hired” in Greenhouse ATS, Make.com automatically triggered a scenario to:
   • Extract relevant candidate data (name, contact info, job details, start date).
   • Create a new employee record in BambooHR, populating all necessary fields.
   • Initiate the necessary data transfer to ADP Payroll, ensuring accurate setup for first paycheck and deductions.
   • Trigger internal notifications to HR, IT, and managers for onboarding tasks.
4. Employee Data Synchronization: We implemented scenarios to ensure ongoing data consistency. Any changes to an employee’s record in BambooHR (e.g., address change, department transfer, salary adjustment) would automatically update the corresponding records in ADP Payroll, minimizing discrepancies and manual reconciliation.
5. Custom Error Handling and Alerts: Critical to any automation is robust error management. Our Make.com scenarios included built-in error handling, automatically logging any failed data transfers and sending immediate alerts to the HR team for intervention, ensuring no data was lost or overlooked.
6. Centralized Reporting Data Lake: While not a full data warehouse, we configured Make.com to push key, aggregated HR data points into a secure cloud database (e.g., Google Sheets or a simple SQL database) nightly. This created a lightweight “single source of truth” for reporting and analytics, accessible to authorized HR personnel.
7. Scalable and Flexible Architecture: The Make.com-based solution was designed for future growth and adaptability. As Mid-Atlantic Manufacturing’s needs evolve or if new systems are introduced, the modular nature of Make.com allows for easy modification and expansion of existing integrations without requiring extensive re-development.

By implementing this Make.com-driven strategy, 4Spot Consulting empowered Mid-Atlantic Manufacturing to transform its fragmented HR data landscape into a cohesive, automated ecosystem, laying the groundwork for greater operational efficiency and strategic HR capabilities.
