# Billing & invoices

Manage your plan, credits, and payment details from one place: [**Billing settings →**](https://app.pletor.ai/?settings=credits)

#### Common questions

<details>

<summary><strong>Where do I find my invoices?</strong></summary>

Open [Billing settings](https://app.pletor.ai/?settings=credits). Past invoices and receipts are listed there, downloadable as PDF.

</details>

<details>

<summary><strong>How do credits work?</strong></summary>

Credits work as a prepaid balance: every run consumes credits, based on the models it uses.&#x20;

Your current balance and usage are shown in [Billing settings](https://app.pletor.ai/?settings=credits).&#x20;

</details>

<details>

<summary><strong>Do credits expire?</strong></summary>

It depends on your plan and credit types.

* **Monthly credits expire**: unused monthly credits expire after a set time (depending on the [plan](https://www.pletor.ai/pricing)). "Use it or lose it."
* **Top-up credits never expire**: these stay until used.

Switch plan [here](https://app.pletor.ai/?settings=plans).
