About CGI Payroll Services

CGI Payroll Services provides comprehensive payroll, tax filing, and Human Capital Management (HCM) solutions to businesses of all sizes across the United States. Their mission is to allow clients to focus on their core operations while CGI handles the complexities of payroll, tax compliance, and workforce management.

The Challenge

Before partnering with NatPay, CGI Payroll Services was managing ACH files directly with financial institutions. While workable, this approach created several operational challenges:

  • Early processing cut-off times limited flexibility and put pressure on internal teams.

  • ACH returns were difficult and time-consuming to manage.

  • Transactions were not warehoused, which made ACH reversals a “nightmare.”

  • There was no built-in underwriting support when onboarding new clients.

As CGI continued to grow, these inefficiencies created additional administrative burden for their tax and finance teams and took time away from serving their clients.

Goals

CGI Payroll Services set out to:

  • Implement a more efficient, centralized ACH solution.

  • Reduce the administrative burden associated with returns, reversals, and exceptions.

  • Strengthen security and fraud prevention around payroll disbursements.

  • Free internal teams to focus more on client needs and less on back-office processes.

The NatPay Solution

To address these challenges, CGI Payroll Services chose NatPay to modernize and streamline their ACH processing and payment workflows.

Solutions in use include:

  • ACH Direct Deposit – Centralizing and simplifying ACH processing, including returns and reversals.

  • My.DirectDeposit.com – Providing a convenient way for employees to manage their direct deposit information.

By shifting away from a bank-driven ACH process to NatPay’s platform, CGI gained:

  • Warehoused transactions, which make corrections and reversals significantly easier.

  • Fraud notifications that go beyond what traditional financial institutions typically provide.

  • Underwriting support for new clients, helping CGI manage risk more effectively.

Implementation

The transition to NatPay was described by CGI as straightforward and low impact.

Implementation was “a breeze,” with NatPay’s team handling most of the heavy lifting. The migration was seamless for CGI’s internal teams, and day-to-day operations were not disrupted. Staff quickly adapted to the new workflow due to its clarity and ease of use.

Results & Impact

Since implementing NatPay, CGI Payroll Services has seen meaningful improvements across operations, security, and resource allocation.

1. Simplified ACH Operations

  • The ACH process is now more streamlined and easier to manage.

  • Returns processing has become more organized and less time-consuming.

  • Warehoused transactions have turned what used to be challenging reversals into a manageable, straightforward process.

2. Enhanced Security and Fraud Protection

  • NatPay provides fraud notifications that CGI did not receive from their financial institutions.

  • Potential fraudulent activity can be identified earlier, helping protect both CGI and their clients’ employees.

  • This added layer of protection has increased confidence in the overall payment process.

3. Reduced Administrative Burden

  • CGI’s tax and finance departments spend less time wrestling with ACH issues and manual corrections.

  • Internal resources can be more focused on client needs and higher-value work.

  • Payroll cycles are smoother, with less stress during peak processing times.

4. Better Experience for Employees

  • Employees benefit from reliable direct deposits and stronger fraud monitoring.

  • The added security and proactive notifications help build trust in the payroll process.

By partnering with NatPay, CGI Payroll Services transformed ACH processing from a time-consuming operational challenge into a streamlined, secure, and scalable system. What was once defined by early cut-offs, complex reversals, and administrative strain is now characterized by flexibility, stronger fraud protection, and simplified workflows. With warehoused transactions, proactive fraud notifications, and underwriting support in place, CGI has gained greater control over risk while freeing internal teams to focus on delivering exceptional service to their clients. The result is not just improved back-office efficiency—but a more confident, secure, and client-focused payroll operation built for continued growth.

NatPay has completely transformed how we manage ACH processing. Before, we were constantly fighting early bank cut-off times, messy returns, and difficult reversals. With NatPay, those headaches are gone. Their warehoused transactions, fraud notifications, and support underwriting new clients give us a level of control and security we never had with traditional financial institutions. Implementation was a breeze—NatPay did all the heavy lifting—and our tax and finance teams now have more time to focus on serving our clients. It’s been a game-changer for CGI Payroll Services.
