# Invoices

> Understand Sandbox invoice types for subscriptions, wallet usage, and overdrafts

Sandbox generates different types of invoices based on your usage and billing model. Each invoice type provides a clear breakdown of charges and payments for specific services.

<Info>
  You can [view and download invoices](https://help.sandbox.co.in/portal/en/kb/articles/view-and-download-invoices) from your Console at any time.

## Invoice types

Sandbox generates three types of invoices depending on your billing activity.

<ParamField path="Subscription invoice">
  Generated when you pay for a subscription plan at the start of each billing cycle (monthly or annually). Once paid, your subscription becomes active and includes access to 200+ APIs, API keys, and monthly quota. No additional subscription charges apply during the billing period unless you upgrade or change your plan.

</ParamField>

<ParamField path="Wallet charges invoice">
  Generated for wallet usage on APIs that incur per-call charges. Customers add funds to the Sandbox Wallet using a payment gateway or bank transfer. Wallet charges are aggregated daily and deducted from your wallet balance. The invoice summarizes all billable API usage for the period.
</ParamField>

<ParamField path="Overdraft invoice">
  Generated when you exceed your monthly quota with overdraft enabled. Additional API calls beyond quota are charged at the per-call rate defined in your plan. At the end of each billing cycle, a separate invoice lists all overdraft usage and charges.
</ParamField>

## Managing invoices

All invoices are available in your Console under the billing section. You can download GST-compliant invoices for accounting and tax purposes.

<Tip>
  Set up automatic payment instructions to ensure uninterrupted service for subscription renewals.
