Short answer

How can I preview billing changes in Zuora using AI?

Your agent uses the preview_subscription tool to calculate how specific modifications to a subscription will change upcoming invoices. This lets you catch errors in billing logic before you apply changes to real accounts. You'll see the exact breakdown of the projected charges below.

The simulation outcomes

What you get from a preview

Running a simulation gives you several ways to validate your billing math.

PREVIEW

Projected invoice totals

The AI calculates what the next bill will look like based on your proposed changes. You get a clear view of the new amounts and dates.

VALIDATE

Logic verification

The agent checks how new product additions or quantity changes interact with existing discounts. This ensures your pricing rules work as expected.

AUDIT

Change impact logs

You receive a summary of every adjustment made during the simulation. This helps you compare the old billing state against the new one.

HUMAN

Final approval

The AI never commits changes to Zuora. You review the simulation results and decide whether to push the updates to the live system yourself.

The workflow

What your AI does when the simulation request arrives.

The agent handles the heavy lifting of calculating complex billing cycles so you don't have to do the math manually.

  1. Identify the target

    The agent looks up the specific subscription in Zuora to understand its current state, including active products and existing terms.

    preview_subscription

  2. Apply proposed changes

    The agent applies your requested modifications, like adding a new seat or changing a tier, to a virtual version of the subscription.

    preview_subscription

  3. Calculate the delta

    The agent runs the math to determine the difference between the current billing schedule and the new one.

  4. Present the summary

    The agent provides a plain English breakdown of the projected charges, tax implications, and timing for your review.

FAQ

Common questions about billing simulations

  • 01

    Will this change my actual customer bills?

    No. The preview tool only simulates changes. Nothing is written to your Zuora account unless you manually perform the update yourself.

  • 02

    Can the AI delete a subscription?

    No. This MCP only includes tools for previewing and viewing subscription data. It cannot delete or terminate subscriptions.

  • 03

    Does it handle prorated charges?

    Yes. The simulation tool calculates proration based on the current billing period and the date of the proposed change.

  • 04

    Can I use this to fix errors in Zuora?

    You can use it to verify what a fix would look like, but the AI cannot execute the correction in your live environment.

  • 05

    What if the subscription has complex custom pricing?

    The agent uses the existing pricing logic defined in Zuora to run the simulation, so it respects your custom rules.
