The payment term starts to run from the day the invoice is emitted to be paid.

Customization per customer
In the Advanced section, you can enter the custom payment term negotiated with your customer.
Grace period
For invoices with usage-based products, Hyperline uses a grace period, defined as a number of days, to leave invoices open before sending them for payment. This period allows you to review the invoices before they are finalized. At the end of this period, Hyperline automatically sends invoices for payment. The default duration is 3 days, but you can configure it on the Settings → Invoicing page.Behavior during the period
During this period, newly ingested events for the invoice billing period are considered and invoices are regularly updated, so they have the latest accurate usage data. Invoices in grace period don’t have a unique number (not part of the sequential numbering). Hyperline generates this number when the invoice is finalized/ready to be paid.
When the invoice leaves the grace period and is ready to be paid, a webhook
invoice.ready message is sent. You can check more details about webhooks in
the webhooks page.
