Korellis Systems Control improves job management and cash flow with Joblogic
Korellis Systems Control moved from desktop-based processes to Joblogic’s web-based HVAC software, improving visibility across field operations, streamlining invoicing and supporting more efficient day-to-day job management.
The story in brief
Korellis Systems Control is a Hammond, Indiana-based union mechanical contractor, providing professional, cost-effective control systems and commercial HVAC solutions. Since 1985, the business has built a strong reputation for quick response, professionalism and reliable service, supporting school districts, churches and other commercial buildings in and around Chicagoland.
As a specialist mechanical contractor managing work across multiple field staff and customer sites, Korellis Systems Control needed a simpler, more connected way to stay involved in the day-to-day management of its mechanics and field teams. Having previously used desktop-based job management software, the business wanted a web-based system that could improve visibility, simplify scheduling and make administration easier.
By implementing Joblogic’s HVAC software in January 2018, Korellis Systems Control was able to streamline the way jobs were logged, scheduled and managed from the office through to the field. With Joblogic, the team can manage mechanics more effectively, capture time, materials, parts and labour information, and carry job details through to invoicing more efficiently, helping the business improve productivity, workflow and cash flow.
Korellis Systems Control needed a simpler way to manage their mechanics and a more efficient method for handling invoices.
Having already used job management software in the past, they implemented Joblogic into their business in January 2018. Since then, Korellis Systems Control has seen improvement with their overall workflow.
Korellis Systems Control provided constructive suggestions which Joblogic assessed and embedded into their long-term improvement process. We are always open to customer feedback.

Challenge & Opportunity
Korellis Systems Control needed to modernise the way jobs, field teams and financial processes were managed across the business.
They needed a more efficient way to stay involved in the day-to-day management of its mechanics and field teams
Their previous desktop-based system limited accessibility and made it harder to manage work flexibly across the business.
Scheduling and deploying jobs to the right mechanics was time-consuming and needed to be more organised.
Capturing time, materials, parts and labour for each job created extra administration and slowed down invoicing
Slower invoicing processes had the potential to delay payments and affect cash flow.
By moving to Joblogic, Korellis Systems Control could bring greater structure, visibility and efficiency to its HVAC service operations.
A centralised, web-based system offered the opportunity to improve visibility across field operations and give the team greater control over daily job management.
Moving to a cloud-based platform created the opportunity to access job information more easily, helping office staff manage work from one connected system.
Smarter scheduling created the opportunity to assign jobs more efficiently, improve response times and support better use of available resources.
Connecting job costing with invoicing created the opportunity to reduce manual admin, speed up billing and improve accuracy across the process.
Faster, more streamlined invoicing created the opportunity to improve cash flow by reducing delays between job completion and payment.
“It is now so easy to bill time and materials - everything is already in the system and shows up on the invoice.”
