Billing Scenario

At 15:30:00 on October 15, 2024, a user purchased a change management package with 200 change tickets for one month. After a period of time, the current capacity cannot meet service requirements. At 10:30:00 on October 27, 2024, the user purchased the package with 300 change tickets. After the package expires, the user does not renew the package. How much the user should be charged in both October and November?

Billing Analysis

Yearly/Monthly fee:

• From 10:30:00 on October 15, 2024 to 10:30:00 on October 27, 2024, the user needs to be billed for using the change management package with 200 change tickets for 12 days.
• From 10:30:00 on October 27, 2024 to 23:59:59 on November 15, 2024, the user needs to be billed for using the change package with 300 tickets for 19 days.

  The unit price of the change management package is $0.12 USD per month for each change ticket. Note: The unit price of the package is an example. The actual unit price is subject to the purchase page.

  Specification change fee = Quantity after change × Unit price × Remaining duration – Quantity before change × Unit price x Remaining duration

  Remaining duration (excluding the current hour for the change) = 4 days and 13 hours/31 days + 15 days/30 days ≈ 0.6465 days (Remaining duration in October/Total duration in October + Remaining duration in November/Total duration in November)

  Specification change fee = 300 × $0.12 USD x 0.6465 – 200 × $0.12 USD × 0.6465 = $7.758 USD

Therefore, the total fee is calculated as follows: $0.12 USD per month for each change ticket × 200 + $7.758 USD = $31.758 USD (Fee for the first purchase + Specification change fee)
