I monitor accounts with severely past due invoices by making sure notices are sent in a timely manner. Exerting all collection efforts via email or call to make sure that payment will be collected as early as possible. Answering to customer's dispute and making sure that it is addressed properly and not hold the collection process for long. Verifying and processing refund request from customers. Updating Accounts Receivable files for updates in a timely manner to make sure that all accounts are executing the correct collection step.
