Can I upgrade a Single App User to a Standard User in Vtiger?

Yes, you can upgrade a user license from a Single App User to a Standard User both during the trial period and after the subscription begins.

• During the trial period: You can upgrade users without any charges. Billing will be calculated based on the user types and count at the end of the trial when the subscription starts.
• After the subscription starts: If you upgrade a user, the system may generate an invoice based on the updated user count and pricing plan. In such cases, the billing can be adjusted to charge only for the remaining duration of the subscription period.
