I have extensive experience with various billing systems, including SAP and Oracle. To ensure accuracy, I follow a rigorous QA process that includes cross-referencing invoices with purchase orders, validating rates against contracts, and conducting regular audits. I also utilize automated testing tools to identify discrepancies early in the billing cycle, which helps in maintaining high accuracy levels.

When discrepancies are found, I first document the issue thoroughly, including the source of the error and the impact on the billing. I then escalate the issue to the relevant department, such as IT or Finance, depending on the nature of the error. I work closely with them to resolve the issue promptly and implement preventive measures to avoid future occurrences.

I focus on streamlining processes by automating repetitive tasks where possible, such as using scripts for data validation. I also conduct regular training sessions for the billing team to ensure they are up-to-date with the latest billing procedures and software. Additionally, I implement performance metrics to monitor efficiency and identify areas for improvement.

I stay current with industry regulations and ensure that our billing processes adhere to all relevant laws and standards. This includes regular audits to verify compliance and updating internal policies as needed. I also collaborate with legal and compliance teams to address any regulatory changes and implement necessary adjustments to our billing procedures.

One challenging issue I faced was a recurring discrepancy in invoice amounts due to a misconfigured rate table. I first isolated the root cause by comparing the billing data with the rate table and identifying the incorrect entries. I then worked with the IT team to correct the configuration and retested the system to ensure the issue was resolved. Finally, I implemented a new QA check to prevent similar issues in the future.
