This article explains how billing and invoicing works for a prepaid customer.


The usage summary for prepaid accounts is generated on the 1st of every month for the preceding month i.e. Invoice for the period 1st January to 31st January will be generated on February 1st and has 3 main sections:


  1. Usage charges

  2. Recurring charges

  3. Credited payments





1. Usage Charges: This is the amount that a customer has incurred by using Plivo platform throughout the month. In this case, from Jan 1 to Jan 31.




2. Recurring charges: This section is the sum of:

  • Rental charge for total numbers on the account as on 1st of any month: This section shows the total numbers present in the account on 1st of the month (in this example, 1st of February)

  • Setup and rental charge for numbers purchased in the month of January: This section lists the numbers that were purchased in the month of January. This amount is already paid by the customer as and when they purchase a new number as per prorated calculation. 







3. Payments: This section is the sum of all the successful payments made on the account in a month


Coming to the calculation part:


a. Usage charge: USD  0.47

b. Recurring charge: USD 2.16

Rental charge for all numbers as on Feb 1: USD 1.76

Setup and rental charges for numbers purchased in Jan: USD 0.40

c. Payments: USD 0

d. Balance: 0.47+2.16-0 = 2.63 i.e. I owe Plivo USD 2.63.


Another thing to note is negative and positive balance showing on the invoice:

  • A negative amount occurs when the recharge on the account is more than the usage. This means that the account balance at the end of the billing period is positive. 

  • The positive amount occurs when the recharge on the account is less than the usage. This means that the account balance at the end of the billing period is negative.

During a month, an account will never be in a negative balance (given that auto recharge is enabled and all card recharges are approved) because the account will get recharged as soon Plivo credits go below the set threshold. However, as the invoices are generated on the 1st of the following month and we also charge for monthly rental on an advance basis, the invoice shows a balance. The pending amount is debited and customers will see a higher recharge on the 1st of every month.


In order to check the actual spend for a month, the customer might have to refer to both December and January invoice:

  • December invoice: For numbers present in your account as of January 1

  • January invoice: For usage charges and new numbers purchased for the period January 1 to January 31


Short Code charges: SC fee is charged on 1st of a month (usually for a quarter). The customers will see the complete payment for a quarter in the first month and no charge for SC in the next two invoices.
