A short, AI-generated podcast-style summary of this article.

When you purchase an OmniAI add-on partway through your current billing cycle, the first charge is adjusted based on the remaining time in that cycle. From the next billing cycle onward, the full monthly add-on price applies.

How Mid-Cycle Add-on Billing Works

If an add-on is purchased after the billing cycle has already started, the first charge is prorated.

Prorated billing means you pay only for the portion of the billing cycle during which the add-on is active.

After the current billing cycle ends, the add-on is billed at its full monthly price together with your subscription.

Example: Adding an Extra Member Mid-Cycle

Assume a customer is subscribed to Flexito Essentials at $59/month for a billing cycle running from May 1 to May 30.

An Extra 1 Member add-on costs $19/month.

If the customer adds the extra member on May 15, there are 15 days remaining in the 30-day billing cycle.

First Billing Cycle

The prorated add-on cost is:

$19 × 15 / 30 = $9.50

The total charge for that billing cycle becomes:

$59 + $9.50 = $68.50

So, for the current billing cycle, the customer pays $68.50.

Following Billing Cycles

From the next full billing cycle onward, the complete monthly add-on price applies:

$59 base subscription + $19 Extra Member = $78/month

As long as the subscription and add-on remain active, the recurring monthly total is $78/month.

Proration Formula

You can understand the first add-on charge using this formula:

Monthly add-on price × remaining days in billing cycle ÷ total days in billing cycle

The result is the prorated add-on charge for the current billing cycle.

Important Billing Notes

  • Mid-cycle add-on charges are prorated for the remaining portion of the current billing cycle.

  • The full monthly add-on price applies from the next billing cycle onward.

  • Add-ons are billed separately from the base OmniAI subscription.

  • All listed prices exclude applicable taxes.

  • Third-party provider charges may apply separately.

  • Subscription, add-on, and usage payments are non-refundable.

Frequently Asked Questions

What does prorated billing mean?

Prorated billing means the add-on charge is adjusted according to how much of the current billing cycle remains when the add-on is purchased.

Will I pay the full add-on price immediately?

Not when the add-on is purchased partway through the billing cycle. The first charge is calculated for the remaining portion of that billing cycle.

When does the full add-on price begin?

The full monthly add-on price applies from the next complete billing cycle.

Does this change my base subscription price?

No. The base subscription price remains the same. The prorated add-on charge is added to the current billing cycle, and the full add-on charge is added from the next billing cycle onward.
