TRXN automatically generates invoices from active subscriptions through the GenerateInvoicesJob. This ensures that recurring charges are billed on time without manual intervention.

​
How it works

1

Scheduled execution

The GenerateInvoicesJob runs on a regular schedule, typically daily. It evaluates all subscriptions to determine which ones are due for billing.
2

Subscription processing

The job iterates through all subscriptions and checks billing eligibility based on the subscription’s next billing date and the current time.
3

Active phase check

Only subscriptions with an active phase containing recurring items are processed. If a subscription has no active phase or the active phase contains only one-time items, it is skipped.
4

Due date calculation

The job compares each subscription’s next_billing_date with the current time. If the billing date has arrived or passed, the subscription is eligible for invoice generation.
5

Invoice creation

For each eligible subscription, the job generates an invoice with line items corresponding to the recurring phase items in the active phase.

​
Invoice structure

When an invoice is generated, it contains:
  • Invoice level — customer, account, and subscription references
  • Line items — one line item per subscription phase item
  • Pricing — uses overridden prices when set, otherwise falls back to the base product price
  • Quantities — reflects the quantity specified in each phase item

​
Example

​
Duplicate prevention

The invoice generation system includes safeguards to prevent duplicate invoices. If an invoice has already been generated for a billing period, the job will not create another one for the same period.

​
Billing cycle anchors

Invoice generation respects billing cycle anchors. When a subscription has an anchor set, the next_billing_date calculation aligns with the anchor date rather than the subscription creation date.

​
Initial invoices

When a subscription is first created, the system may generate an initial invoice depending on the proration behavior:

Subscriptions

Multi-phase subscriptions with flexible pricing and automatic transitions.

Billing cycles

Control when recurring charges occur with billing cycle anchors.
