CartThrob Add-ons
First-party CartThrob add-ons extend checkout, recurring billing, store operations, and post-order workflows. Add-on names link to their documentation when documentation is available; store links point to the ExpressionEngine Add-on Store.
Commercial Add-ons
Subscriptions
Take recurring payments for memberships, subscriptions, layaway, and donations using token-based gateway vaults. Subscriptions pairs with Permissions Manager when subscription purchases should grant member access.
Permissions Manager
Create permission items, assign them to members, and sell content access through CartThrob checkout. Use it for member-only content, protected downloads, or subscription-backed permissions.
Gift Certificates
Sell gift certificates, redeem codes into session balance, and apply gift balances during checkout. The add-on handles certificate purchase, redemption, and balance tracking.
Global Item Options
Define reusable item option groups and price modifiers that apply across product entries. Use it when many products share the same configurable options but still need per-entry overrides.
Abandoned Cart Notifications
Send staged follow-up emails when customers start checkout but do not complete their purchase. The docs use the legacy Expired Cart Notifications path for this add-on.
Fees
Add automatic fee line items to the cart based on location, cart contents, item options, or custom cart data. Fees can be flat or percentage-based and may be configured as taxable when needed.
Order Manager
Manage orders, run supported gateway actions, resend emails, generate reports, and export order data from the control panel. Order Manager ships with CartThrob, so there is no separate ExpressionEngine Add-on Store link.
Free Add-ons
PayTrace Payments
PayTrace Payments is a free CartThrob payment gateway add-on, currently listed as version 1.1.0 in the ExpressionEngine Add-on Store. It adds PayTrace payment processing support for CartThrob stores.
Retired Add-ons
Credits
Let members purchase store credits and apply them toward cart totals during checkout. This add-on is retired, but the documentation remains available for existing installs.
Multi Address Shipping
Capture multiple shipping addresses per order, group cart items by address, and calculate costs separately for each destination. This add-on is retired and retained for legacy reference.
Wish List / Gift Registry
Store wish lists as channel entries and let customers move wish list items into CartThrob checkout. This add-on is retired and retained for legacy reference.
Invoice
Create invoices in the control panel, email them to customers, and let customers add invoices to cart for payment. This add-on is retired and retained for legacy reference.
