Using CartBot for deferred fees for rentals and demos

CartBot is compatible with Downpay and we recommend using it when you'd like to auto add products to the cart and disallow removal.

Example of use cases:

• Selling a product from your store for a 20$ trial/rental and adding a 0$ deposit 100$ security deposit product to the cart in order to be able to store a card on file and have the ability to charge the customer if they do not return the product.

To complete setup for the above example

1. Set up Downpay and create a new 0$ upfront deposit purchase option and assign your Security deposit product.

2. Install CartBot and click Create a bot and use the Products bot trigger

3. Add the 20$ trial product in the When a customer's cart includes: box

4. Add the deposit product in the Then automatically add: box and click Set subscripiton option and choose the Downpay selling plan you've created

5. Review the settings in CartBot to make sure the behaviour suits your workflow and save the bot.

The bot will now add the 0$ security deposit to the cart and on Checkout, you will see a due later total of the $100 that was deferred.

6. Should you also wish to place an authorized hold for the remaining balance, please review our Flow workflow on how to set this up.
