Complex Payroll, HR and Absence Implementation for a Leading Logistics Provider

Delivering a high-pressure implementation across 10 pay groups, multiple payroll frequencies and time and absence integration.

This case study shows how a leading logistics provider successfully went live with a complex payroll, HR and absence implementation despite coordination delays, data issues and post-go-live fixes.

About The client

Americold

The client is a major provider of temperature-controlled warehousing and logistics services focused on the storage and transportation of perishable goods.

The project covered an end-to-end payroll, HR and absence implementation. The scope included 10 pay groups, time and absence integration, and multiple payroll frequencies made up of 5 weekly and 5 monthly payrolls.

Over a 4 month programme, the delivery team supported implementation, payroll continuity and post-go-live stabilisation while working across several client-side payroll and HR stakeholders.

How It Went

The Challenge

  • Poor coordination across 10 pay groups slowed data migration and created knock-on delays across later project phases.
  • Time and absence sign-off was delayed, and payroll inputs supplied through the interface file did not sync with iHCM2 after implementation.
  • One weekly payroll was configured against incorrect pay schedule details provided by the client after go-live.
  • Employees needed to be transferred from live pay groups to parallel phase pay groups after go-live, creating operational and timing risk.
  • Incorrect employee codes across 600+ employees caused payment errors and required reversals and repeated fixes.
  • Missing reporting data affected GL reports, pension reports and average holiday reporting.
  • Errors in sales and contract documentation created invoicing issues that required cross-team resolution.

How We Did it?

Our Solution

PHRism’s payroll team supported the client through a structured implementation and stabilisation approach built around control, responsiveness and payroll continuity.

The team implemented iHCM2 for payroll, HR and absence, while also using the Data Fix Utility, Import Tool and time and absence integration to keep the programme moving. Where interface issues blocked automation, interim manual processes were used so payroll runs could continue.

Because the project involved 10 pay groups and both weekly and monthly payrolls, close coordination was essential. The team worked across multiple client contacts, supported payroll specialists during weekly pay runs, corrected employee codes, managed pay group transfers and resolved configuration issues as they surfaced.

Delivery intensity was high throughout. The team worked 15-hours in each day and weekends to meet deadlines, then continued support after go-live until payroll had stabilised across all groups.

Joint Effort

The Collaboration

The engagement required daily coordination between the implementation team, payroll specialists and several client-side HR and payroll contacts.

As a functional consultant within the PHRism payroll team, the role focused on cross-team coordination, payroll support during weekly runs, high-priority issue resolution and maintaining momentum through complex post-go-live changes.

When documentation gaps, reporting issues and payroll exceptions appeared, the team worked closely with the client and internal stakeholders to diagnose problems quickly and keep the programme on track.

FAQ's

About This Project

A payroll, HR and absence implementation usually includes discovery, data migration, system configuration, pay group setup, integration work, testing, go-live support and post-go-live stabilisation.
Timelines vary by scope, payroll complexity, data quality and integrations. In this project, the implementation and support period ran across 4 months.
Time and attendance integration helps move approved working time data into payroll accurately. When that connection fails or sign-off is delayed, manual work and payroll risk usually increase.
Complexity increases when different teams, pay schedules, employee groups and reporting needs must be aligned at the same time. Coordination and data accuracy become critical.
Common post-go-live issues include incorrect pay schedules, employee coding errors, reporting gaps, integration failures and urgent fixes needed to protect payroll continuity.
Businesses should look for proven delivery capability, strong stakeholder coordination, hands-on go-live support, experience with complex payroll structures and the ability to resolve issues quickly under pressure.
