1# Billing
 2
 3We use Stripe as our payments provider, and Orb for invoicing and metering. All Pro plans require payment via credit card or other supported payment method.
 4For invoice-based billing, a Business plan is required. Contact [sales@zed.dev](mailto:sales@zed.dev) for more information.

 6## Billing Information {#settings}

 8You can access billing information and settings at [zed.dev/account](https://zed.dev/account).
 9Most of the page embeds information from our invoicing/metering partner, Orb (we're planning on a more native experience soon!).

11## Billing Cycles {#billing-cycles}
12
13Zed is billed on a monthly basis based on the date you initially subscribe. You'll receive _at least_ one invoice from Zed each month you're subscribed to Zed Pro, and more than one if you use more than $10 in incremental token spend within the month.
14
15## Threshold Billing {#threshold-billing}
16
17Zed utilizes threshold billing to ensure timely collection of owed monies and prevent abuse. Every time your usage of Zed's hosted models crosses a $10 spend threshold, a new invoice is generated, and the threshold resets to $0.
18
19For example,
20
21- You subscribe on February 1. Your first invoice is $10.
22- You use $12 of incremental tokens in the month of February, with the first $10 spent on February 15. You'll receive an invoice for $10 on February 15
23- On March 1, you receive an invoice for $12: $10 (March Pro subscription) and $2 in leftover token spend, since your usage didn't cross the $10 threshold.
24
25## Payment Failures {#payment-failures}
26
27If payment of an invoice fails, Zed will block usage of our hosted models until the payment is complete. Email [billing-support@zed.dev](mailto:billing-support@zed.dev) for assistance.

29## Invoice History {#invoice-history}

43## Sales Tax {#sales-tax}
44
45Zed partners with [Sphere](https://www.getsphere.com/) to calculate indirect tax rate for invoices, based on customer location and the product being sold. Tax is listed as a separate line item on invoices, based preferentially on your billing address, followed by the card issue country known to Stripe.

47If you have a VAT/GST ID, you can add it at during checkout. Check the box that denotes you as a business.
