# Billing and usage

> How MantrixFlow checkout, plan changes, monthly allowances, and plan limits work.

Use the application billing page to review your current plan, usage, checkout options, invoices, and billing portal.

## Current allowances

| Plan       | Pipelines | Delivered rows per month |
| ---------- | --------: | -----------------------: |
| Free       |       `5` |                 `25,000` |
| Plus       |      `20` |              `1,000,000` |
| Pro        |      `50` |             `10,000,000` |
| Enterprise | Unlimited |                Unlimited |

See [Pricing](/pricing) for current monthly and annual prices.

## Start a paid plan

1. Open **Settings → Billing**.
2. Choose Plus or Pro and a monthly or annual billing period.
3. Continue to the Dodo Payments hosted checkout.
4. Review the final price, taxes, payment methods, and billing period.
5. Confirm the purchase.
6. Return to MantrixFlow after checkout completes.

Do not close the checkout page until the payment provider shows a result. If the application still shows the previous plan, refresh the billing page after the payment confirmation is processed.

## Change a plan

The billing page shows whether a plan change starts immediately or at the next renewal. Review the effective date in the hosted flow before confirming the change.

Use the billing portal for supported payment-method, receipt, invoice, and cancellation actions.

## Pipeline limits

When a workspace reaches its pipeline limit, MantrixFlow blocks creation of another pipeline. Existing pipelines and their history remain available.

## Delivered-row limits

Rows count after successful destination delivery. Rows that fail before delivery do not count toward the delivered-row allowance.

MantrixFlow warns workspace owners as usage approaches the monthly allowance. When delivered rows reach the plan limit, new runs pause until the workspace upgrades or the allowance resets.

## Billing support

For a checkout, invoice, cancellation, or account-access problem, contact [support@mantrixflow.com](mailto:support@mantrixflow.com). Include the workspace name and billing email, but never send passwords, access tokens, or database credentials.
