**

John and Priscilla, business owners facing a substantial sales tax audit, initially confronted a liability of $18,000. By partnering with Certus, we successfully reduced their liability to just $2,000.

**Here's How We Helped:**

- **Audit Review & Strategy:** We analyzed their financial records, identifying eligible deductions and ensuring compliance.
- **Effective Communication with Auditors:** By verifying taxable transactions, we worked with the state to supply supporting documents.
- **Minimized Liability:**  We successfully reduced their liability from $18,000 to just $2,000.

**The Outcome:**

Even though this audit was almost 8 hours of billable work, the clients decided it was worth it. John and Priscilla only paid taxes on items with verifiable liabilities, ensuring a fair and accurate assessment while alleviating financial stress.
