# Billing transactions and balance history
> Billing transactions provide a historical view of all billed charges for your organization. If you have questions about charges, invoice details, or want to analyze the underlying data, start with billing transactions.
**Important:** The **Statements** page has been deprecated. Detailed transaction history is now available on the **Transactions** page and can be downloaded as an XLSX or CSV file.
The **Transactions** page provides a historical view of all billed charges for your organization, and has two views of your billing history. The **Balance history** tab displays a summary of transactions against your balance history, by month. The **Transaction history** tab displays a detailed list of all billed transactions for your organization that can be downloaded for analysis or reporting purposes.
## Balance history tab
The **Balance history** page displays a summary of transactions against your balance history, by month. Totals are calculated at the end of each calendar month. It includes the following information:
* **Billing period**: The month and year of the billing period.
* **Charges**: Running total of all charges during the billing period.
* **Credits and adjustments**: Total of all credits and adjustments during the month.
* **Total charges**: The total amount of charges less credits and adjustments during the month.
Each row also links to the detailed **Transaction history** for that month.
## Transactions tab
On the **Transactions** page, you will see a list of historical transactions for your organization, grouped by charge type, with filters for date range and SIM tags. This page has some differences in content and functionality depending on your organization's billing type.
**Prepaid organizations** with an account balance:
* Can view transactions for the current month
* Data usage transactions may be aggregated per SIM to meet a minimum charge threshold of \$0.25
**Postpaid organizations** with monthly invoicing:
* Can view transactions only for prior months, after invoices have been generated for that month
- Data usage transactions are aggregate per SIM, by Universal Network Code (UNC), per month. You can map transactions to specific networks to determine exact session-level charges.
To download the transactions as an XLSX file, click the **Download** button in the top right corner of the page. To download other file formats, hover over the transactions table, click the three-dot menu that appears, select **Export**, then choose the desired file format.
