How CFO Mark Delaney unlocked sales tax refunds to drive major business expense reduction across six states
Follow Mark’s journey to see how overlooked financial data turned into a six-figure recovery.
Financial complexity increases as companies expand across state lines, especially when tax rules, vendor billing practices, and exemption requirements vary by jurisdiction. Many mid-sized manufacturers operate with lean finance teams focused on compliance and daily operations, leaving little time to revisit historical transactions for hidden errors. As a result, overpayments often remain buried in routine expenses.
Mark Delaney, CFO of a manufacturing company operating across six states, believed the company’s finances were in good shape. But tightening margins signaled that something was off. His core challenge was identifying whether years of unnoticed tax overpayments were preventing the company from recovering a legitimate, multi-year sales tax refund.
As margins tightened, CFO Mark Delaney realized the company may have overlooked years of sales tax overpayments, putting a legitimate multi-year refund at risk.
Keep reading to discover how a structured review revealed a significant recovery opportunity.
Navigating the Financial Landscape of a Manufacturing Firm
Mark’s company had grown steadily through regional expansion, new supplier relationships, and increased production capacity. Each move added operational complexity, particularly in how vendors charged sales and use tax across different states. Tax rules shifted, exemption eligibility varied, and invoice reviews focused more on payment accuracy than tax validation.
Over time, this environment created blind spots. Minor discrepancies, including misapplied tax rates, taxable classifications on exempt purchases, and inconsistent vendor billing, became normalized. Without a structured review process, these issues blended into standard operating costs.

The Budget Review That Forced a Deeper Investigation
The breaking point came during a quarterly budget review with senior leadership. Rising material costs and freight expenses were already tightening margins, and every department was being asked to justify its upcoming expenditures.
As Mark walked through the financials, one trend stood out. Indirect tax expenses had increased steadily over several years, despite a relatively consistent purchasing volume.
Indirect tax costs kept rising even though purchasing volume stayed the same, revealing hidden inefficiencies.
The leadership team wanted clarity on why costs were rising in an area that should have been stable. Mark realized he could not give a precise explanation. Internal audits had confirmed compliance, but they had never focused on whether taxes charged by vendors were actually correct. His team ensured bills were paid, and returns were filed, but they did not have the time to recheck tax treatment across thousands of historical transactions.
After the meeting, Mark reviewed a small batch of invoices on his own. He quickly noticed inconsistencies. Similar items were taxed differently by different vendors. Some purchases that should have qualified for exemption had full tax applied.
In other cases, tax appeared to be layered on top of use tax accruals. These were not dramatic errors on single invoices, but patterns that could accumulate into significant overpayments.
A quick invoice review exposed patterns of misapplied tax, pointing to years of potential sales tax refund opportunities.
At that moment, Mark understood the scale of the issue. Recovering a legitimate sales tax refund would require a structured, multi-year comprehensive expense analysis reconstruction supported by specialized tax expertise, not a simple internal review.
Determined not to let potential recoveries slip away, he decided it was time to bring in outside specialists who could thoroughly investigate past overpayments and determine whether the company was owed meaningful recoveries tied to a sales tax refund.
How The SALT Group Uncovered a $385K Sales Tax Refund Through Expert Expense Review and AnalysisReconstruction
Mark began looking for a firm with deep multi-state tax expertise and a proven process for large-scale and comprehensive expense analysisreconstruction. He needed specialists who could analyze years of transactions without overwhelming his internal team. That search led him to The SALT Group.
From the outset, their approach was different. Instead of sampling invoices or reviewing only recent periods, The SALT Group performed a comprehensive historical analysisreconstruction of transaction data across vendors, purchase categories, and state jurisdictions. Their consultants examined how sales and use tax had been applied line by line, validating taxability, exemption eligibility, and vendor billing accuracy.

The review revealed consistent patterns of overpayment. Vendors had applied tax based on default settings rather than product-specific tax rules. Exemption documentation had not always been used at the point of sale. In some cases, use tax had been accrued even when sales tax had already been charged.
Individually, these discrepancies were small. Across multiple years and thousands of invoices, they accumulated into a substantial sales tax refund opportunity.
The SALT Group managed the end-to-end process, including documentation, jurisdictional analysis, and direct coordination with state tax authorities. Because the engagement was performance-based, Mark’s company faced no fee until refunds and other benefits were identifiedBecause the engagement was performance-based, Mark’s company faced no upfront cost and paid only from realized recoveries.
The results confirmed the scope of the issue. The structured review secured a $385,000 sales tax refund across multiple states by recovering accumulated overpayments and introduced stronger controls that supported long-term business expense reduction.
