Instead of starting from scratch, simply generate a quote from an existing subscription, update the terms (or add new phases), and let Hyperline automatically apply the changes once the customer signs. ## Subscription contracts We've improved how contract details are handled within subscriptions. **Commitments are now replaced by contract duration**, with start and end dates set dynamically based on the subscription. This provides a clearer structure and ensures contract terms align with your billing cycle, making it easier to track and manage long-term commitments. ## ACH with GoCardless Hyperline now supports **ACH direct debit via GoCardless**, giving you more payment flexibility for your US customers. Now, you can offer an additional, cost-effective payment method for businesses that prefer direct bank transfers over credit cards. ## Manage quote ownership Quote ownership is now **a dedicated, editable field** in Hyperline. By default, it's assigned to the creator (whether from the interface or CRM), but if needed, users with the right permissions can update it. ## Custom tax codes for more regions Tax compliance just got easier. You can now define **custom tax codes** beyond the EU, covering specific cases like **reverse charge or tax exemption**. Make sure that your tax rules align with international requirements and integrate smoothly with your accounting software, such as Exact Online. ## Invoicing entity language You can now configure the default language for your invoices and credit notes for each invoicing entity. Previously, this was inferred from the invoicing entity's country, but now you have more flexibility. ## Organisation-based billing refresher We've revamped the way we display customer hierarchies and organisation-based billing options on the customer page. The relationships between customers are now clearer and more structured. ## ISO 27001 certified Following our **SOC 2 compliance** announcement, Hyperline is now **ISO 27001 certified**. This milestone reinforces our commitment to the highest security and compliance standards, ensuring that your data remains protected at all times. *[More details about security & compliance](../security)*
