Situation: Painful Invoice Processes & Time-Consuming Timesheets
Without a centralized system, Lewis’s payroll processing and customer invoicing were challenging, slow, and manual. To put it in perspective, the company processed 86,000 spreadsheets for payroll each year. This required nearly 45 full-time employees to complete, and the General Foreman had to enter the same data four times.
“The general foremen were being pulled in so many directions that it was causing inefficiencies in operations,” says Huntley Hedrick, VP of IT at Lewis.
Weekends of time-consuming work made for unhappy employees, payroll delays, slow revenue realization, and poor customer experiences.
Solution: Data Platform & Custom Application
Using ProArch’s Dataware Data Platform, the team integrated the HR and ERP systems into a data warehouse and then developed a custom application called “Tiempo.”
The data modeling in the background simultaneously calculates payroll and invoices based on customized rules by location, job type, pay rate, employee, and start/end time.
Results: A Game-Changer All Around
- Lewis has experienced a 90% reduction in the overall effort with a clear, streamlined process for time entry, timesheet creation, and approval.
- Advanced reporting capabilities using data from different systems.
- Before, Lewis experienced a high volume of invoice adjustments. Now, it is a 3% adjustment rate.
- Customers have a better experience, and Lewis can realize revenue faster.
- Lewis owns the tool so they can avoid future costly and complex ERP upgrades and customization.
For the general foremen, Tiempo has been transformational. Hedrick added, “What I’ve observed with the rollout of Tiempo has been greater than anything that I’ve ever seen in my career with how accepted it’s been in such a short amount of time.”

How Does ProArch’s GuardAssist Managed Services Maintain Security During Routine Changes?
About
A large power generation facility supporting critical infrastructure relies on a complex identity environment spanning on-premises and cloud systems.
After completing onboarding to ProArch’s GuardAssist Support Managed Services, a routine personnel change revealed a latent security risk that could easily be overlooked without continuous monitoring and automated controls.
Services
During a standard offboarding process, a departing employee’s account was disabled in Microsoft Entra ID and associated licenses were removed. At the time, the administrator believed the process was complete.
However, the user account remained active in the organization’s on‑premises Active Directory Domain Services (AD DS). During the next directory synchronization cycle, the account was automatically re-enabled in the Azure environment.
This left an enabled, unlicensed account vulnerable to login attempts and potential compromise, posing a significant security risk.
ProArch’s GuardAssist Support Managed Services detected the issue quickly through its automated alerting and compliance monitoring capabilities.
Using Microsoft Lighthouse and ProArch’s Alert Processor, the system identified the account as “Not Compliant (Regressed)” across multiple security baselines and automatically generated support tickets.
ProArch engineers analyzed and consolidated the alerts, then remediated the issue by:
- Disabling the user account in on-premises AD DS
- Moving the account to a non-synchronizing organizational unit (OU)
- Ensuring the offboarding process was fully completed and protected from reoccurrence
Subsequent compliance scans verified that the remediation was effective, with all security indicators returning to a compliant state.
Ongoing monitoring and enforcement of identity controls across hybrid systems helped the organization minimize manual effort and ensure consistent protection.
As a result, the organization’s environment remained stable and secure, requiring no further action. The organization benefited from reduced risk and improved confidence in their security posture.
Industry
- Power Generation
Challenge
- A routine offboarding process left an identity account active due to directory synchronization, creating a hidden security risk.
Solution
- GuardAssist Managed Services used continuous identity monitoring and automated compliance alerts to detect and remediate the issue.
Result
- The risk was resolved early, compliance was restored, and ongoing monitoring reduced manual effort.
