O.Z. Enterprises: How O.Z. Enterprises Doubled Revenue and Reduced AP Time by 90%
About O.Z. Enterprises
Founded in Pittsburgh, PA, O.Z. Enterprises is the region’s leading independent provider of building automation systems (BAS) — specializing in Tridium Niagara solutions that integrate HVAC, lighting, security, and metering for optimized energy use and streamlined facilities management. Since acquiring the business, CEO Ryan Birtwell has led O.Z. to double its revenue and expand from 22 to nearly 50 employees, all while maintaining a focus on quality and customer service in the education, healthcare, and telecommunications sectors.
The Challenge
Like many growing businesses, O.Z. Enterprises faced a major AP bottleneck. Ryan, the CEO, personally handled financial tasks — spending 2–3 hours every Sunday manually entering bills line by line into QuickBooks to ensure accurate job cost tracking. Some bills contained 150+ line items, including dollar value, quantity, sales tax, and shipping.
This manual data entry extended beyond AP: Ryan also manually entered employee timesheets into QuickBooks for payroll — a 3-hour weekly chore that created duplication and the risk of errors. Managing complex union rules and job cost allocations further complicated the process, making it difficult to scale without adding admin staff.
“Sunday night, I used to spend 2–3 hours entering all our bills into QuickBooks, line item by line. Sometimes there would be 150 items in a single bill.”

The MakersHub Solution
Ryan implemented MakersHub to transform both AP and timesheet management. The platform’s AI-powered Smart Data Capture extracts line-item details with 100% accuracy, eliminating manual entry. Bills can be emailed directly to MakersHub, where they’re instantly processed — ready for review and approval in seconds, with automatic syncing to QuickBooks.
On the timesheet side, MakersHub’s integrated Timesheet Tracker allows employees to submit hours online via mobile or desktop, ensuring accurate job cost allocation. Union rules and benefits are preserved, and the job list syncs seamlessly from QuickBooks — eliminating duplicate entry and errors.
With MakersHub, Ryan’s team can:
- Automatically capture and code line-item details from every bill — no more manual entry
- Submit and approve timesheets in one place — faster and more accurate
- Sync all data to QuickBooks in real time — improving financial accuracy
- Focus on high-value growth projects instead of data entry
“It’s a complete game-changer. What used to take hours now takes minutes — and my team can focus on customer-facing work that actually grows the business.”
