This includes all primary data storage, replication, multi-region backup data transfer and storage, and search indexing storage and replication. For this article, units of bytes are calculated as follows: * One kilobyte (KB) means 1000 bytes. * One megabyte (MB) means 1000 kilobytes. * One gigabyte (GB) means 1000 megabytes. * One terabyte (TB) means 1000 gigabytes. ### Data storage The data storage category represents the total storage size of all standard and custom objects, including all standard and custom attributes. Storage in this category is calculated by multiplying the quantity of each Klass type by its corresponding storage size and then taking the sum of the total. **Klass type** **Storage size** Company 0.1 KB Customer 0.1 KB Conversation 0.5 KB Message 0.2 KB Attachment 0.1 KB Event / Audit Log 0.07 KB Note 0.2 KB **Custom object data** **Storage size** KObject 0.5 KB Custom attribute (including custom attribute strings on standard objects) 0.05 KB **Note:** KObject storage size excludes using the Data attribute. ### Storage limits Storage limits are allocated by organization and user, with defaults for the organization by subscription plan type and per-user allocations by subscription plan. **Default storage allocation per organization\*** The values in the table below are allocated by default for all organizations. _\*If you have created multiple organizations under your account, the amounts below will be allocated pro-rata across the number of organizations on your account._  **Plan** **Default storage** **Additional storage allocation (seat-based plans)** **Additional storage allocation (conversation-based plans)\*** **Data storage** **Data storage** **Data storage** Professional (legacy plan) 2.5 GB 125 MB per full-time user n/a Business (legacy plan) 5 GB 250 MB per full-time user n/a Enterprise 10 GB 500 MB per full-time user 150MB / 1k committed conversations Ultimate  20 GB 1 GB per full-time user 300MB / 1k committed conversations The values in the table above are allocated for each full-time user license on your subscription plan at the end of each calendar month during your subscription term in addition to the per-organization allocation. For clarity, if your organization adds or removes full-time user licenses within a calendar month, your default storage allocation will be adjusted based on the number of licenses at the end of the calendar month. No additional storage allocation is provided for seasonal or collaboration users. _\*If your organization has purchased a custom usage-based license that measures usage every month, the additional data storage per full-time user will be based on a straight-line average of full-time users across the commitment period instead of the actual usage in any given monthly period._ ### Exceeding default storage allocations If you exceed your default storage allocations, Kustomer reserves the right to enforce storage limits, including charging for additional usage, restricting the creation of new data, and/or reducing existing data storage usage. ### View platform usage You can view your current usage of your platform storage in **Settings ![](https://cdn.kustomerhostedcontent.com/media/570fad9d9001bc1000163b28/1ef7081a666403777165feaa7bcb3c04.png)** **\>** **Platform > Platform Usage** at any time. For more information on how to manage your data, see [Manage platform usage](http://help.kustomer.com/manage-platform-usage-data-HJkfk28Kkx). ### Purchase additional data storage You can contact [customersuccess@kustomer.com](mailto:customersuccess@kustomer.com) to purchase additional storage and add it to your default limits. If you do not purchase additional excess data storage prior to the end of the calendar month in which you exceeded the limits on your subscription plan, Kustomer will invoice you on a monthly basis for the amount of additional data storage at the rates set forth above to raise your limits to the amount you need to bring your data storage storage in compliance, and you agree to pay such data storage fees, as applicable. **Note:** If you have questions about your data storage or managing storage limits, please reach out to your aligned CSM or to [customersuccess@kustomer.com](mailto:customersuccess@kustomer.com).
