Overview
By default, Lago dates invoices on the first day of the new billing period (e.g., November 1st for an October usage and subscription). Some businesses need invoices dated on the last day of the billing period instead (e.g., October 31st) for accounting or compliance reasons. This feature gives you control over the issuing date displayed on your invoices. Note that this is configured at the Billing Entity level and applies to all customers under that entity. However, you can override it for specific customers when needed.Invoice settings
Issuing date anchor
This setting determines which issuing date appears on your invoice.Issuing date adjustment
This setting controls what happens when an invoice is finalized after the anchor date, especially when a grace period greater than 0 is configured.Examples
The following examples show how different combinations of settings affect the invoice issuing date for a subscription with a billing period from October 1st to October 31st. The grace period determines when the invoice is finalized after the billing period ends.Common use cases
Standard billing (default)
Best for most businesses. Invoice dates reflect when invoices are actually issued, which simplifies payment tracking and customer communication.
Period-end accounting
Ideal for businesses that need invoices dated within the same month as the service period for revenue recognition or accounting compliance. Example: An October subscription invoice will always show October 31, even if generated in November.
Fixed period start dates
Useful when you want consistent invoice dates aligned to billing cycle starts, regardless of processing delays. Example: Monthly invoices always dated on the 1st of each month.
