# Product updates April, 2025
> Hyperline April 2025 release: Anrok tax integration, audit logs, QuickBooks, promotion codes, and CRM data sync observability for sales workflows.
## Anrok
Hyperline now supports **tax calculation and reporting with Anrok**. As an alternative to Hyperline's built-in tax engine, you can now choose to use your Anrok account to compute VAT and sales taxes.
## Audit logs
To improve **traceability and monitoring of activity** within a Hyperline account, new audit pages are now available.
You can track:
* App activity: Lists all actions performed in the account, the associated entities, and the users/source who performed them.
* Email activity: Shows emails sent, their opening status, and the recipients, including those in BCC.
*This feature is accessible for the account owner.*
## QuickBooks
**Hyperline is now integrated with QuickBooks**. Your invoices, credit notes, and payment reconciliation data can be automatically and seamlessly synced to your QuickBooks account for accounting.
## Promotion codes
In addition to the existing coupon features, Hyperline now allows you to create promotion codes on a coupon with various options — such as time limitations, restrictions to specific customers, plans, or products. These promotion codes can be entered by your prospects and customers on the checkout subscription page.
*This feature is available exclusively through the Hyperline API.*
## CRM data sync observability
You can now **monitor issues related to CRM integration with Hyperline** directly within your account. Full details are provided, including the sync source and destination, action performed, error information, changed fields, entity ID, and more. Additionally, issues can be retried, retriggering the object data synchronization process.
