Final answer:
Brent should call the client once a week to inquire about the overdue payment, being consistent and professional with each interaction and conveying the importance of settling the bill without being aggressive.
Step-by-step explanation:
When considering how often Brent should call the client to politely ask when payment will arrive, it isn't necessarily about a fixed frequency, but rather about consistency and professionalism. Brent should initially send a friendly payment reminder via email or a phone call a few days after the invoice becomes overdue. If there's no response, following up weekly can be a reasonable approach. During each contact, he should remain polite and professional, as maintaining a good relationship with the client is essential. It is crucial, however, to also be firm about the payment terms agreed upon. A certain level of persistence shows the importance of the matter without being overly aggressive.
For instance, in a credit card company scenario, there is a clear penalty for late payments, such as a $10 initial charge and an additional $5 daily fee. While Brent's situation may not involve such penalties, being consistent and clear about expectations can help in resolving the issue swiftly. As illustrated by the action taken by Noel upon discovering an overpayment, immediate and assertive communication is imperative in matters of financial discrepancies or overdue payments. In business dealings, such diligence can prevent substantial monetary loss or complications.
