## TL;DR
days_until_due only works with collection_method send_invoice. On charge_automatically invoices Stripe charges the payment method right away and the due-days setting is meaningless. Switch the invoice or customer default to send_invoice if you want net terms.

```text
days_until_due ignored charge_automatically
```

## Use this when
- An invoice charges immediately despite days_until_due being set.
- You want net-30 terms but the customer is on auto-charge.
- Your code sets days_until_due on every invoice and it only sometimes works.

## Not for this skill when
- The collection method is already send_invoice and terms still fail. Check the customer default.
- The invoice was manually finalized. Manual finalization has its own rules.

## Steps
1. ('Read the invoice collection_method. Verify: it is charge_automatically.', 'Decide the intent: auto-charge customers should not get net terms. If terms are correct, change collection_method to send_invoice. Verify: the invoice shows a due date.', 'Check the customer-level default collection method, since invoices inherit it. Verify: new invoices will use the right method.', 'For mixed customers (some auto-charge, some terms), set collection per invoice, not per customer. Verify: each invoice carries its own method.', 'Resend or re-finalize as needed. Verify: the customer sees terms, not an immediate charge.')

Compatibility: Stripe Billing invoices API, all client versions.

## Why it happens
The two collection methods are different products: charge_automatically means "bill the card now," send_invoice means "email terms and wait." days_until_due belongs to the second product. When both are set, charge_automatically wins because charging immediately is the stronger instruction. The API accepts the combination silently, which is why the due-days setting looks ignored rather than rejected.

## Edge cases / pitfalls
- Switching a customer to send_invoice stops auto-collection on all future invoices. Confirm with finance.
- Past-due auto-charge invoices converted to send_invoice still need manual collection.
- Your invoice template may print "due in N days" on auto-charged invoices. Fix the template per method.
- Test both methods in your invoice code paths; silent field conflicts are test-shaped bugs.
