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.”

ProArch Secures Vendor Access and Strengthens Cyber Resilience at Power Generation Facility

About

A gas-fired generation facility that is part of ProArch’s OT Insights & Managed Services (OTIMS) program detected an unexpected remote access connection coming from a monitoring system tied to the plant’s CEMS (Continuous Emissions Monitoring System).

A third-party vendor had installed TeamViewer on a monitoring device for remote diagnostics outside of formal access protocols.

The device was directly connected to the SCADA network, creating an unmonitored and unsecured remote access path. The setup introduced a serious vulnerability that could be exploited by threat actors to move laterally into critical OT systems.

Services

  • Remote Access Detection
  • Risk Escalation and Response Coordination
  • Segmented Access Policy Implementation
Challenge
  • Unapproved remote access software (TeamViewer) installed by a third-party vendor
  • Connection path was active and unmonitored
  • Device was directly linked to the SCADA network, bypassing segmentation
  • Risk of lateral movement into OT environment went unnoticed
Solution
  • 24/7 monitoring as part of OTIMS detected the anomaly
  • ProArch escalated the issue to plant leadership immediately
  • Remote access was disabled within hours
  • Segmented access controls were introduced to enforce secure vendor access
Result
  • Strengthened Cyber Resilience: Continuous visibility into remote connections and vendor activities from OTIMS prevent future unwanted third-party access.
  • Operational Continuity: By catching vulnerabilities before exploitation, the plant ensures consistent uptime and performance protecting production and revenue.
  • Vendor Accountability & Process Maturity: Vendors now follow formal procedures increasing accountability and reducing dependence on informal support arrangements.
  • Data-Driven Decision-Making: With improved visibility into OT assets and network activity, the plant can make informed investment and maintenance decisions.

Challenge

  • Unapproved TeamViewer access bypassing SCADA segmentation and exposing lateral-movement risk.

Solution

Result

  • Cyber resilience strengthened, operations protected, vendor accountability improved, and visibility increased.
