# Other Housekeeping
### Cloudformation stacks created
Do not delete the CloudFormation stacks that were created during the initial onboarding. We use the permissions granted during then that helps us purchase and sell RIs/Savings plan.
If you have any further questions, please contact us at .
### Should I purchase RIs or savings plans in future
Dotted is 100% responsible for all the purchase decisions we make. That means you have no financial risk when it comes to commitments.
If you were to make these purchases on your own, Dotted would not take responsibility, and the risk would be on you. We strongly recommend that you avoid doing this.
### Spinning up an AWS service or discontinuing one
Dotted AI continuously scans your purchase history and tries to forecast your future spend. While AI can do its job well, we recommend that you inform us of your plans in advance (if possible) so that we can be even more efficient with our commitments. You can leave us a message on the chat or email us at . We will soon embed this feature in the product itself to make it more convenient.
