How One Telecom WFM Team Met the OBBB Without Missing a Paycheck

When the One Big Beautiful Bill was released, payroll and workforce management teams across the U.S. had to work out how it would change the way they calculate and report overtime.

For one U.S.-based telecom company, that job landed on the workforce management (WFM) team. They had to build a brand-new overtime calculation, roll it across hundreds of pay rules, and prove it worked, all without changing a single dollar on anyone's paycheck. Here's how they did it, and how test automation saved them nearly a month and caught a costly defect just before go-live.

The challenge: real OBBB payroll implications

With the release of the One Big Beautiful Bill, the company's WFM team was tasked with creating a separate overtime calculation to support the bill's guidelines. The work had two goals running side by side:

• Keep paying overtime according to company policy, exactly as employees were used to.
• Support the IRS requirements for the OBBB by calculating OBBB overtime hours separately and reporting them to payroll.

And it all had to happen without impacting employees' paychecks.

The solution: new pay codes, 600 updated distributions, automated tests

The team tackled the problem in three moves.

1. Built new pay codes for OBBB hours. Rather than altering the existing overtime logic employees are paid on, they added dedicated pay codes that capture the additional overtime calculation the OBBBA requires. The paycheck math stayed untouched; the new codes ride alongside it.
2. Updated all 600 Pay Code Distributions in their WFM. Each distribution had to report OBBB hours to the payroll system so payroll could calculate the qualified amount according to the guidelines. Missing even one would mean incomplete reporting for some group of employees.
3. Put TestAssure to work. The team reused existing automated test scripts and built new ones to cover the new configuration. That let them validate the change across pay rules, locations, and scenarios far faster than manual testing could.

The design choice that matters most here is separation. By layering the OBBB calculation next to the existing overtime rules instead of rewriting them, the team protected what employees actually get paid while adding the new reporting the IRS requires.

The results: four weeks back and a defect caught in time

Nearly four weeks of testing time saved. Because so much of the regression and new-configuration testing ran through automated TestAssure scripts, the team cut almost a month from its testing timeline. On a regulatory change with a hard deadline, that's a month of breathing room.

A California overpayment stopped before release. The automated scripts flagged a defect right before go-live. If it hadn't been found, it could have resulted in California employees being overpaid for overtime.

Because the team caught it in testing, the issue never reached a paycheck.

What other WFM and payroll teams can take from this

• Add, don't rewrite. Build the OBBB calculation alongside existing overtime rules so pay stays stable while reporting changes.
• Inventory every touchpoint. Pay codes are only half the job; every distribution that feeds payroll has to carry the new hours.
• Test across every location. Broad automated coverage is what surfaced the California defect before release.
• Automate before the deadline, not after. Reusable scripts paid off twice here: in speed, and in catching a defect manual testing could easily have missed.

This team's approach shows that a regulatory change doesn't have to mean payroll risk. With a clean configuration strategy and automated testing behind it, they supported the OBBB guidelines, kept every paycheck intact, and finished weeks ahead of where manual testing would have left them.
