A User would like to know why there is a discrepancy on Total Storage Size in Billing Information and NetSuite Account Center.
The Storage Info data in NetSuite Account Center is updated monthly, on the first week of the following month. For example, the data showing on the Account as of July 8, 2020 is the storage information data for the month of June 2020.
Meanwhile, for more current storage information, see the Total Storage Size (MB) entry on Billable Components tab of the Billing Information page at Setup > Company > NetSuite Account Information > View Billing Information (Administrator). The Total Storage Size (MB) information on the Billing Information page is updated weekly, as can be seen on the Component Usage tab.
NOTE: If in any case, you would like to increase the Total Storage Size of your account, kindly reach out to your dedicated Customer Success Consultant.
