How invoice errors turn into recovered revenue

By Jesse Sanchez. 

Invoice IQ helps contractors compare supplier invoices against agreed pricing to identify overcharges and recover revenue. 

For contractors managing material costs across hundreds or thousands of invoices, missed pricing errors can quickly drain revenue. On this episode of Roofing Road Trips®, Karen Edwards spoke with John Albright of InvoiceIQ about why invoice review matters and how technology can make a manual, time-consuming process more manageable. 

Q: How does InvoiceIQ help contractors verify supplier pricing? 

At its core, InvoiceIQ addresses a simple but costly gap in contractor operations: the difference between agreed pricing and the amount charged on a supplier invoice.  

“When you get a supplier invoice mailed or emailed to you. We upload that with your agreed price sheet with your supplier and it checks to make sure they’re charging you the right price.”  

John’s explanation underscores the importance of verification, especially for contractors managing supplier relationships, pricing agreements and high-volume material purchases. By comparing invoices with agreed price sheets, the platform helps contractors catch discrepancies before they become absorbed as a cost of doing business. 

Q: Why can invoice review become harder as a business grows? 

In John’s experience, growth can quickly outpace manual invoice review. As supplier spending increases, checking each invoice line by line becomes harder to staff, manage and verify consistently.  

“Once it got up to $40 million, the only thing I could do to combat not having the team check invoices was to just check my P&Ls. How much money was I making on each house I was building, each building I was building? That generally made my anxiety go down.”  

Without that detailed review, contractors may have to rely on project-level profitability checks instead. While that approach can show whether a job remained profitable, it may not reveal where pricing errors occurred or how much revenue was lost. 

Q: Why should contractors pay attention to smaller material charges? 

According to John, invoice errors do not need to appear on large-ticket items to affect the bottom line. He explained that contractors often focus on the most expensive products on an invoice, such as boilers or major equipment, because those costs stand out immediately. But overcharges on smaller materials can be just as damaging when those items are purchased repeatedly across many jobs. 

“He started raising the price on 25-cent fittings and things like that, which, when you consolidate the whole account, is 80% of what you’re actually paying, not a $3,500 boiler or a $5,000 boiler.” 

Contractors may naturally focus on expensive equipment or more obvious line items, but smaller charges can carry just as much risk when they escape review. Over time, even minor overcharges can compound across an account and turn into meaningful lost revenue. 

For companies managing multiple projects, disciplined invoice review can help protect margins, improve job costing and strengthen supplier accountability. InvoiceIQ gives contractors a way to identify discrepancies before they are absorbed as a cost of doing business.
