# Billing and Subscriptions
What is the order process?
1. Choose a data plan and subscription type in the [order form](https://tardis.dev/#order).
* available data plans
* [Perpetuals](#what-is-included-in-perpetuals-data-plan)
* [Options](#what-is-included-in-options-data-plan)
* [Spot](#what-is-included-in-spot-data-plan)
* [Derivatives](#what-is-included-in-derivatives-data-plan)
* [All Exchanges](#what-is-included-in-all-exchanges-data-plan)
* available subscription types
* [Solo](#what-are-the-differences-between-subscription-types)
* [Academic](#what-are-the-differences-between-subscription-types)
* [Pro](#what-are-the-differences-between-subscription-types)
* [Business](#what-are-the-differences-between-subscription-types)
2. Proceed to checkout where you provide your email address and payment details. [See accepted payment methods](https://paddle.com/support/which-payment-methods-do-you-support/).
* accepted payment methods
* Credit Cards (Mastercard Visa Maestro American Express Discover Diners Club JCB UnionPay)
* PayPal
3. Successfully complete your payment and receive an API key via email that allows you to [download CSV datasets](/downloadable-csv-files/overview.md) and [access historical data via API](/api/quickstart.md). The API key is valid while your account has an active subscription.
{% hint style="info" %}
For larger orders we also accept [pay through invoicing](#can-i-pay-through-invoicing).
{% endhint %}
Do you provide discounts?
No. We do not provide discounts, but we offer [different subscription types](#what-are-the-differences-between-subscription-types) for solo traders, academic users, professionals and businesses.
How does subscription-based access work?
Subscription-based access uses monthly, quarterly or yearly billing. An active subscription gives access to newly collected market data as it [becomes available](/faq/data.md#what-is-the-historical-market-data-delay-in-relation-to-real-time), plus [existing historical market data](#do-subscriptions-include-access-to-historical-data-as-well). The historical range depends on the billing interval.
When ordering a subscription, you choose:
* Subscription type — [Academic, Solo, Pro, or Business](#what-are-the-differences-between-subscription-types)
* Data plan — [Perpetuals](#what-is-included-in-perpetuals-data-plan), [Options](#what-is-included-in-options-data-plan), [Spot](#what-is-included-in-spot-data-plan), [Derivatives](#what-is-included-in-derivatives-data-plan) or [All Exchanges](#what-is-included-in-all-exchanges-data-plan)
* Billing interval — [monthly, quarterly or yearly](#do-subscriptions-include-access-to-historical-data-as-well)
For example, an "[All Exchanges](#what-is-included-in-all-exchanges-data-plan)" Business subscription with [yearly billing](#do-subscriptions-include-access-to-historical-data-as-well) gives access to **all available existing historical data via API and CSV files**, plus new data as it becomes available during the yearly billing interval.
The product access scope depends on your subscription type:
* **Academic and Solo** — [downloadable CSV files](/downloadable-csv-files/overview.md) only
* **Pro and Business** — [downloadable CSV files](/downloadable-csv-files/overview.md), [raw data replay API](/api/quickstart.md), [tardis-machine](/tardis-machine/quickstart.md), and [instruments metadata API](/api/instruments-metadata-api.md)
What are the differences between subscription types?
{% hint style="warning" %}
Academic subscriptions are currently disabled for new subscriptions. They remain listed for reference; when available, they require confirmation of eligibility, for example using university (@edu) email address.

{% hint style="info" %}
Academic, Solo and Professional include one active API key; Business includes up to 10. All API keys share the account's [API request and data transfer limits](/api/rate-limits.md).
Each API key can be used from one IP address at a time. [Real-time market data streaming](/faq/general.md#do-you-support-consolidated-real-time-market-data-streaming) does not require an API key.
{% endhint %}
Do subscriptions include access to historical data as well?
Yes, **depending on the billing interval**, subscriptions include access to existing historical market data as well:
* **Yearly billing:**
* **Business subscriptions:** access to **all available historical data** since **2019-03-30** for majority of the supported exchanges ([see exchange details page](/historical-data-details/overview.md#per-exchange-historical-data-details) for exact date for particular exchange)
* **Academic, Solo, and Pro subscriptions:** access to **4 years of historical data**, e.g., subscription that has started at 2026-01-01 includes access to historical data since 2022-01-01
* **Quarterly billing:** access to **12 months of historical data**, e.g., subscription that has started at 2026-01-01 includes access to historical data since 2025-01-01
* **Monthly billing:** access to **4 months of historical data**, e.g., subscription that has started at 2026-01-01 includes access to historical data since 2025-09-01
Historical data access is not a rolling time window, but a fixed starting date since when historical data is available for your subscription.
