In a previous role, I faced a situation where a client disputed a large invoice due to a discrepancy in service dates. I reviewed the billing records and discovered an error in the system that had misaligned the dates. I corrected the error, provided the client with a detailed explanation and supporting documentation, and negotiated a revised payment schedule that was acceptable to both parties. This experience taught me the importance of thorough documentation and clear communication in resolving billing disputes.

I prioritize tasks by first identifying overdue accounts and prioritizing those with the highest balances or those that are at risk of going into collections. I then focus on accounts with upcoming due dates, ensuring that I communicate with clients before their payments are due. I use a task management system to track each account's status and set reminders for follow-ups. This approach helps me stay organized and ensures that no account slips through the cracks.

To improve payment compliance, I start by ensuring that invoices are clear, accurate, and sent out promptly. I also establish regular communication with clients to understand their payment processes and any potential issues they may face. Offering multiple payment options, such as online payments or payment plans, can also increase compliance. Additionally, I follow up consistently but politely, reminding clients of their obligations without being overly aggressive, which can sometimes lead to better payment outcomes.

When a client refuses to pay, I first review the account history to ensure there are no misunderstandings or unresolved issues. If the client is still non-compliant, I escalate the matter to my supervisor and provide all relevant documentation. In some cases, I may suggest involving a third-party collection agency or legal counsel to pursue the debt. Throughout the process, I maintain clear and professional communication with the client to avoid damaging the relationship while still pursuing the owed funds.

I have extensive experience with automated billing systems, such as SAP and Oracle. To ensure data accuracy, I regularly audit the system's output by cross-referencing it with manual records and client-provided data. I also participate in system updates and training to stay current with any changes that could affect billing accuracy. Additionally, I implement double-checking procedures within my team to catch any discrepancies before invoices are sent out, which helps maintain high data accuracy.
