Customer Testimonial

“We were struggling with QuickBooks:  No easy way to pay vendors by job, customer invoicing was difficult, having to manually produce G702/G703 AIA documents, no document management, and on and on.  With Cumulus Apps Job Cost we’ve now moved from always trying to catch up on paperwork and accounting issues to really being able to grow our business.  So now we have real-time information about our jobs and can make timely adjustments to ensure we’re profitable.  It’s amazing what a difference a great job costing and accounting solution can make for a business!”
