Overview
This article applies to self-serve ChatGPT Business billing for standard ChatGPT seats and usage-based Codex seats. Read our overview article to learn more about ChatGPT Business.
Note: As of April 2, 2026, we’ve changed the pricing structure for ChatGPT Business and have reduced the price of standard ChatGPT seats by by USD $5 per month (note that prices will vary depending on your specific region and local currency). If you are on a monthly plan, the new, lower price will be reflected on your next bill. If you’re on an annual plan, it will be reflected at your next renewal. In both cases, you’ll receive a credit applied to your next subscription renewal to account for the price change. Read more about the credit refund.
ChatGPT Business is built around 2 types of seats: standard ChatGPT seats and Codex seats. Each seat type determines what a user can access and how you are billed for that user.
| Seat type | Included access | Billing model | Minimum seats required |
|---|---|---|---|
| Standard ChatGPT seat | ChatGPT and Codex | Fixed per-user, per-month cost | 2 |
| Codex seat | Codex only | Usage-based | No minimum |
Standard ChatGPT seats (fixed cost)
Standard ChatGPT seats are billed per user and require a minimum purchase of 2 standard ChatGPT seats.
Monthly plan: $25 per user per month
Annual plan: $20 per user per month, billed annually
ChatGPT seats include baseline access to Codex, and you can use flexible pricing and purchase workspace credits to extend usage beyond the included rate limits for Codex and for ChatGPT models.
Codex seats (usage-based, no fixed cost)
Codex seats have no fixed monthly seat price. They do not require a minimum starting number of seats, but they do require workspace credits for activity. Read more about how credits work, and refer to the Codex rate card for latest pricing information.
Managing billing in your ChatGPT workspace
You can review and manage seats, payment methods, and other billing settings from Workspace settings → Billing.
A ChatGPT Business workspace can include any combination of seat types – only standard ChatGPT seats, only Codex seats, or a mix of both. Standard ChatGPT seats include core ChatGPT Business workspace access, ChatGPT access, and access to Codex.
Payment methods
ChatGPT Business is a self-serve subscription that currently supports credit and debit card payments only. Invoice billing, bank transfer, wire, ACH, purchase orders, net terms, and split payments are not available for self-serve Business workspaces.
If your organization requires invoicing, contact Sales to discuss a contracted plan such as ChatGPT Enterprise or ChatGPT Education. When reaching out, include your organization name, estimated number of seats, preferred billing cadence, and any compliance or security requirements.
Support cannot convert an existing self-serve ChatGPT Business workspace to invoice billing.
Billing for standard ChatGPT seats
Billing cadence applies to standard ChatGPT seats. Credits for usage-based products are separate, and are covered later in this article.
Monthly plan
Under the monthly plan:
At the start of each billing month, you are charged for your baseline number of standard ChatGPT seats.
If you add standard ChatGPT seats above the baseline during the month, those seats are charged on a prorated basis.
At the beginning of the next billing period, you are charged based on the current number of standard ChatGPT seats for the upcoming month.
If the number of standard ChatGPT seats is reduced below the baseline during the month, the baseline adjusts to the new reduced count at the next monthly invoice date. You are still billed for the baseline number of standard ChatGPT seats during the current billing month.
Monthly plan example
A user buys 10 standard ChatGPT seats at a monthly price of $25 per seat, for a total of $250. On day 10, the user adds 3 standard ChatGPT seats, bringing the total to 13. On the next invoice, the total charge is $375.
13 seats × $25 monthly price = $325
3 extra seats × 20 days used ÷ 30 days × $25 monthly price = $50
Total = $375
Annual plan
Under the annual plan:
At the beginning of the billing year, you are charged for your baseline number of standard ChatGPT seats.
If you add standard ChatGPT seats during the year, those seats are billed on a prorated basis at the end of each monthly true-up cycle.
At the end of a monthly true-up cycle, you are charged for seats above the baseline at a prorated annual rate, and the new standard-seat count becomes the baseline for the rest of the year.
True-ups reconcile actual seat usage with what has already been billed.
If you add 1 times your current baseline or 20 standard ChatGPT seats in a month, you receive an instant invoice for a true-up before the monthly cycle ends, and the baseline resets immediately.
Annual-plan example
A user buys 5 standard ChatGPT seats at an annual price of $20 per seat per month, for a total of $1,200 for the year. On day 10, the user adds 3 standard ChatGPT seats, bringing the total to 8. On the next invoice, the user is charged $700 total for the additional seats for the days used and the remainder of the year.
Invoice 1: 5 seats × $20 × 12 months = $1,200
First monthly true-up cycle: 20 days used ÷ 30 days × 3 seats above baseline × $20 monthly subscription price, plus 3 seats above baseline × $20 monthly subscription price × 11 months remaining in the annual plan
Total = $700
If the owner removes 2 users on day 20 of month 2, nothing changes in the billing process because the seat count remains below the new baseline.
Billing for Codex seats and credits
Codex seats are usage-based seats. They do not incur a fixed recurring seat fee, but they do require workspace credits for activity. Learn more about credits by reading our Help Center article: Flexible pricing for Business and Enterprise/Edu plans. Then refer to the Codex Rate Card for the latest pricing for ChatGPT Business.
If you see a Codex usage-limit banner in Workspace settings, add credits so members can continue using Codex. You can also enable automatic recharge to help avoid future credit interruptions.
When you add the first Codex seat to a workspace that currently has only standard ChatGPT seats, you will be prompted to add credits using the saved payment method.
When you add your first standard ChatGPT seat to a Codex-only workspace, you will be prompted to purchase a minimum of 2 seats using the saved payment method.
Read managing credits and spend controls for step-by-step instructions on adding credits, enabling automatic recharge, and setting workspace limits.
Billing impacts of adding or removing seats
Before adding or removing members, verify the current standard ChatGPT seat count, Codex-seat count, and available credits in the workspace billing area. To understand the mechanics of inviting members and adding seats, refer to our Help Center article: Managing workspaces, people, and access in ChatGPT Business.
Add standard ChatGPT seats
When you add members with standard ChatGPT seats to a ChatGPT Business workspace, you add standard ChatGPT seats to the subscription.
Flexible monthly plan: standard ChatGPT seats above the baseline are billed on a prorated basis.
Annual plan: standard ChatGPT seats above the baseline are billed at the end of the monthly true-up cycle on a prorated basis.
Add Codex seats
When you add members with Codex seats, the seat itself has no fixed monthly cost, but the workspace needs credits for usage.
Remove standard ChatGPT seats
Reducing team size by removing standard ChatGPT seats affects future billing only after the standard ChatGPT seat count drops below the baseline and the billing cycle resets. For the current period, you are still billed for the current standard ChatGPT seat baseline.
If you want to continue offering standard ChatGPT seat access, you must purchase at least 2.
To reduce or remove standard ChatGPT seats,
Sign in as a Workspace Owner.
Go to Workspace settings > Billing
Select Plan
Update the number of standard ChatGPT seats to the desired total.
Confirm the change.
Review the next renewal date. The reduced standard ChatGPT seat count applies to a future invoice or renewal, not the current billed period.
Moving a member with a standard ChatGPT seat to a Codex seat
Changing a user from a standard ChatGPT seat to a Codex seat affects both product access and future billing. Review the seat-type change in Workspace settings > Members page and any related credit requirements before confirming the change. Note that we do not offer refunds for changing from Standard ChatGPT seats to Codex mid-cycle for both monthly and annual plans.
Manage billing information
Only Owners can view and manage workspace billing information.
From the billing settings area, Owners can:
View past invoices
Change credit card details
Update billing information
Cancel the plan through Manage plan
See the next invoice date and amount
See how many standard ChatGPT seats and Codex users are currently in the workspace
Access credit-related controls such as adding credits or enabling auto-top-up if those controls are available in the billing area
Change billing cadence
Owners can change the billing schedule from monthly to annual, or from annual to monthly, for standard ChatGPT seats.
Go to the billing area for the workspace.
Select Manage license.
Select Billing schedule.
Select the new billing schedule, then select Continue.
Select Confirm.
Review the next renewal date, because the change takes effect at renewal rather than immediately.
Examples:
Monthly to annual: if today is July 8, 2024, and the monthly subscription renews on July 17, 2024, changing to annual means the next renewal still happens on July 17, 2024, but the subscription then runs through July 17, 2025.
Annual to monthly: if today is July 8, 2024, and the annual subscription renews on September 17, 2024, changing to monthly means the next renewal still happens on September 17, 2024, but the subscription then runs through October 17, 2024 instead of September 17, 2025.
Manage tax and VAT information
If you are in a region that levies VAT, you can self-identify as a business and enter your Tax ID at checkout. This automatically exempts the purchase from VAT, and the same status applies to future invoices.
Refunds and Cancellations
Note: As of April 2, 2026, we’ve changed the pricing structure for ChatGPT Business and have reduced the price of standard ChatGPT seats by USD $5 per month (note that prices will vary depending on your specific region and local currency).
If you are on a monthly plan, the new, lower price will be reflected on your next bill. If you’re on an annual plan, it will be reflected at your next renewal. In both cases, you’ll receive a credit applied to your next subscription renewal to account for the price change.
Depending on whether you have a monthly plan or an annual plan, we’re applying a pro-rated pricing difference refund to your current billing cycle as a credit to be used for future ChatGPT seat subscriptions.
This is not a cash refund to your original method of payment - the credit will remain on your account and will automatically be applied to your invoice for your next subscription payment.
Note that this credit is not displayed in settings - you can review it in your list of invoices.If you cancel your subscription, choose not to renew, or delete your account, the credit is forfeit. This credit cannot be transferred between accounts, or applied to a new account. The credit cannot be used for Codex or other flexible pricing account features.
ChatGPT seats
Unused standard ChatGPT seats are not refundable once you commit to a seat count on either a monthly or annual plan. ChatGPT seat billing is based on the number of seats selected at checkout, not actual usage.
Owners can adjust your plan’s seat count at the end of your billing cycle for future periods.
Codex seats
Codex seats do not have a fixed monthly charge, and credits are not refundable except in limited circumstances. Learn more.
Owners/admins can cancel your plan from Workspace settings > Billing. Click the Cancel button in the bottom of the page to get started.
