## Partner billing

Our new [partner billing API](/api/moov-accounts/partner-billing/index.md) provides more insight into fees, residuals, and revenue. You can now retrieve information about your partner costs and merchant-generated revenue to reconcile costs and residuals.

On the first day of each month, Moov will generate a statement for your account. Partner statements will include a summary of the following:

- Merchant fees collected for each fee category
- Partner fees assessed for each fee category
- Net income for each fee category
- Residual payment (for revenue-share partners)
- Monthly partner platform fees (if applicable)
- Interchange report

You can access your statements with the [list statements endpoint](/api/moov-accounts/billing/list-statements/index.md). View the new [billing](/guides/billing/index.md) guides for more information.

## Invoicing

Use the [invoices API](/api/money-movement/invoices/index.md) or the [Dashboard](/guides/accept-payments/invoices/index.md#in-the-dashboard) to send professional, branded invoices to your customers and accept payments without relying on third‑party tools.

When you send an invoice, Moov automatically creates a single-use, secure payment link scoped to that invoice and customer. See our [invoices](/guides/accept-payments/invoices/index.md) guide for more information.

## API & SDK versioning

Moov API [v2026.01.00](/api/index.md) is officially released. API [v2026.04.00](/api/v2026.04.00/index.md) is available as an *in development* API and should be used with caution as breaking changes may occur without notice.

> **Warning:** Moov is no longer updating the `latest` API version and it will be removed from our documentation. This version of our API used to be in continuous release as a beta version. Those using `latest` should update to a different version of our API immediately - Moov suggests `v2026.01.00` at this time.

Visit our API [version reference](/api/version-reference/index.md) for details on major releases per version.

SDK versioning will follow the following format:

| API version   | SDK version    |
|---------------|----------------|
| `v2025.07.00` | `25.7.x`       |
| `v2026.01.00` | `26.1.x`       |
| `v2026.04.00` | `26.4.0-dev.x` |

Currently API `v2026.04.00` is *in development*, so the corresponding `-dev.x` SDK version indicates an *in development* version of the SDK and should be used with caution.

## Bug fixes

- Fixed a webhooks bug when fetching an accounts `metadata` and `foreignID`
- Fixed a bug where transfers were getting stuck in sandbox mode
- Fixed a bug in which `createTransfer` was being duplicated for sweeps
