The employer is checking whether the candidate can translate a billing discrepancy into plain client-friendly language, connect every added fee to a real service or approval, and handle the conversation without damaging the relationship.
Respond in role-play form, using 'you' for the client. Open with a warm acknowledgment, list only the actual changes, show the original versus final amounts, and ask a check-in question before moving on.
Start by thanking the client for trusting you with the event, then pivot quickly into the numbers so the explanation feels transparent rather than defensive. Say plainly that the original quotation was built on a specific timeline and a defined equipment list, and that two changes on the day itself moved the final figure. Frame the overtime as a service you were happy to provide, not a penalty, and say that the additional charge covers the crew, venue extension, and utilities that had to be secured beyond the contracted hours. For the projector, explain that the same-day rental came from a third-party supplier at a standard daily rate, and that this was added to the invoice only after you confirmed the client's verbal approval during the event. Show the original amount, then add each line item clearly, and close by asking if the client wants a breakdown per cost or if they have any questions. Keep your tone warm and matter-of-fact, as if you are simply walking a friend through a receipt. Avoid the word "kasi" entirely and never hint that the client caused the problem, because in the Philippine service culture, preserving the relationship matters as much as the explanation itself. End with a soft check-in question, such as whether the breakdown makes sense, so the client feels heard rather than challenged.
Candidates often say 'Kasi po may overtime kayo, tapos nagdagdag kayo ng projector' and sound like they are blaming the client. Instead, phrase it as 'The overtime and the same-day projector added the following amounts' and keep the tone neutral.
Situation
During a mock client call in our events management class, I played the coordinator explaining extra charges after a simulated company dinner. The client had approved overtime and added a projector on the day.
Task
I had to communicate the two cost increases in simple terms, take responsibility for any unclear timing, and get the client to accept the revised final bill without sounding defensive.
Action
I started by thanking the client for choosing the venue and acknowledged the event went well. I then walked through the two changes: overtime was charged per hour after the first ten hours as stated in the original quotation, and the same-day projector was booked through our in-house vendor at a slightly higher last-minute rate. I showed them the original quote line items and the updated figures side by side, then asked if they had questions before discussing payment terms.
Result
The mock client agreed the explanation was clear and said she would have approved payment because she understood exactly where the extra amount came from.
Explain billing line by line and connect each extra charge to a specific client-approved change.
