CartCubes Toolbox for FluentCart 1.2.8 (30 Oct 2026) attaches your own PDFs to the customer order confirmation, and stops a second purchase of an active or trialing subscription. See the Toolbox page and the changelog.
Order Documents
Add the PDFs you want customers to receive with the order confirmation. Useful for a policy, a refund document, and similar files, including for EU orders. You can add up to 20. The label becomes the file name in the email.
The files go with the purchase receipt and the offline order confirmation. Admin, renewal, refund, and shipping emails stay unchanged.

See the Order Documents page.
Block repeat subscriptions
Stop checkout when the billing email already has an active or trialing subscription for a plan in the cart. Canceled, paused, expired, and completed subscriptions can be bought again. One-time products are not affected.
The checkout banner shows the message you write before Place Order. The default is “You already have this subscription.”

See the Block Purchases page.
