Hints

Updated: 11 March 2024

1. Daily Fee Deduction by Order

1. Define a per-order fee rate. For example, feePerOrder = 7.5 Cent.
2. Each time an order is placed, deduct the specified fee from the merchant's account or balance. For instance, if 100 orders are placed in a day, the total fee for the day would be 100 × 7.5 = $7.50. Then deduction rate is 35%, So your actual 100 orders fee will be $4.875

2. Track Daily and Monthly Fees

1. Maintain a daily record of the number of orders and the corresponding fees
2. At the end of each day, add the daily fee to a cumulative monthly fee total.

3. Ensure a Minimum Monthly Fee

1. At the end of the month, compare the cumulative fee total to the minimum fee requirement $15.
2. If the total fees collected during the month are less than $15, calculate the shortfall and deduct it from the merchant's account. For instance: If the total fees collected for the month are $12, the system should deduct an additional $15 - $12 = $3 Tk.

4. Notifications and Reporting

1. Notify the merchant daily about the fees deducted and their current balance.
2. At the end of the month, send a report summarizing the total fees deducted, the shortfall (if any), and the adjustments made to meet the minimum fee requirement.

Example Scenario

• Fee Per Order: 7.5 Cent
• Orders on Day 1: 50 → Fee Deducted = 50 × 7.5 Cent = $3.75
• Orders on Day 2: 100 → Fee Deducted = 100 × 7.5 Cent = $7.5
• ... (similar calculations for the remaining days)
• Monthly Total Fee Collected: $12 Tk (sum of daily fees)
• Shortfall: $15 - $12 = $3
