Engineers working inside a client's facility log time in the client's system, so their paycheck is the employer touchpoint that matters most. An automotive engineering services firm used CloudApper to move those hours into UKG Pro WFM automatically, ending manual re-entry and the pay errors that strained trust with embedded engineers.
Engineering services firms win work by placing their best people inside a customer’s operation. Those engineers badge into the client’s buildings, follow the client’s program schedules and log their hours in the client’s time system. For weeks at a time, the only part of the employer they touch directly is the paycheck. That makes payroll accuracy an HR leadership issue, not just a payroll one. When the one employer touchpoint an embedded engineer sees is wrong, it lands harder than it would for someone sitting down the hall from HR.
A large automotive engineering and testing services firm lived this with engineers stationed inside a major automaker’s facilities. Payroll ran on UKG Pro WFM. The hours lived in the automaker’s own time system. CloudApper connected the two, and the manual step that put engineers’ pay at risk went away.
The Employee Who Never Sees Your Systems
Before the integration, every engineer’s pay depended on a daily manual routine. Someone at the firm downloaded the automaker’s time export, cross-referenced it against payroll records and re-entered the result into UKG. The engineers never saw any of this. What they saw was the occasional short paycheck or a correction on the next cycle.
According to the HR Director at the engineering services firm, “Our engineers did everything right. They logged every hour where the client required it. When their pay was off, it was our process that failed them, and they knew it.”
For a workforce of experienced engineers, that matters. These are people with options, working alongside the client’s own staff every day. Each correction chips at the employer relationship, and HR has fewer chances to repair it because the employee is rarely on the firm’s own site.

Taking the Human Relay Out of Payroll
CloudApper built an integration pipeline on CloudApper iPaaS for UKG that ingests the automaker’s daily CSV export automatically, applies the firm’s contract logic, flags exceptions and syncs clean data to UKG Pro WFM. The pipeline also keeps payroll hours separate from client billing hours, a design covered in depth in how the firm feeds client-owned time data into UKG Pro WFM.
“I used to spend part of every pay week fielding questions from my engineers about missing hours. That conversation has disappeared. They log time once, in the client’s system, and the pay follows.”

For HR, the significant change is that the engineer’s single act of logging time in the client’s system now carries all the way to their paycheck without anyone retyping it. Manual re-entry was where errors entered, the same weak point behind many payroll integration problems between UKG and other systems, and it is gone.
“Pay accuracy is the one promise we make to people we rarely see. Now we can keep it.”

What HR Leaders Gained
The daily download, cross-reference and re-entry process is eliminated. Payroll errors from manual re-entry dropped, so embedded engineers are paid from validated data. HR conversations shifted away from fixing pay problems and toward the career and program questions that keep experienced engineers engaged.

“When pay is right, nobody calls payroll. That silence is the result we wanted.”

The Lesson for Firms With Client-Site Workforces
Any organization whose people work under another company’s systems faces the same exposure, from engineering services to physician staffing firms paying by hospital location. The employer controls very little of the daily experience, so the parts it does control have to be flawless. HR leaders should ask where client-site hours are retyped today, and who absorbs the consequence when that step slips. CloudApper builds the connection so the answer is nobody: the hours flow into UKG under the employer’s rules, and the paycheck reflects the work.
If your employees log time in a client’s system and payroll depends on someone retyping it, talk to CloudApper about connecting that data directly to UKG Pro WFM.
