Does FluentCart support prorated billing for subscriptions or partial periods?

I'm evaluating FluentCart for a subscription-based setup and would love to know if it supports prorated billing and Charge Next Month logic.

Specifically, I'm looking for:

• ✅ Automatic pro rata calculations when a user subscribes or changes their plan mid-cycle
• ✅ Support for Charge Next Month behavior — where purchases after a certain day extend the initial billing period

📅 Example for Charge Next Month:

Let’s say Charge Next Month is set to 20.

• A user subscribes on January 22 → This is after the 20th, so the initial billing period includes:

  • The remainder of January plus
  • The full next billing cycle (e.g., through February 27 for monthly billing)

• A user subscribes on February 10 → This is before the 20th, so the initial billing period includes:

  • Only the remainder of the current cycle (e.g., February 10–27)

🔄 Example for Pro Rata:

• A user upgrades from Basic to Premium on the 15th of a monthly cycle

• FluentCart should ideally:

  • Charge only the pro rata difference for the remaining days
  • Adjust the next billing cycle accordingly

Does FluentCart support this kind of logic natively, or would it require custom development or add-ons?

Any insights or experience would be greatly appreciated!

Thanks! 😊
