# Customer payment terms and due dates

Customer payment terms that prefill receivable due dates.

Store optional **Payment terms** on the customer master so new receivable invoices prefilled **Due date** from your commercial terms. Cortena applies a clear priority: **manual due date on the invoice wins**, then customer terms, then subscription terms, then invoice date fallback.

**Who this is for:** AR admins who standardize Net 14 / Net 30 per customer and clerks who compose subscription or one-off receivables without retyping due dates.

## 1. Set payment terms on the customer

1. Go to **Receivables → Customers**.
2. Open or create a customer.
3. In the customer form, set **Payment terms** (optional), for example *Net 30* or your workspace’s configured term list.
4. Save the customer.

Terms appear on the customer list/detail for reference; they drive due-date prefill on **new** drafts, not retroactively on issued invoices unless you edit the invoice.

## 2. How due date is prefilled

When Cortena creates or opens a receivable draft:

| Priority | Source |
| --- | --- |
| 1 (wins) | **Due date** you set manually on the invoice |
| 2 | **Payment terms** on the linked **Customer** |
| 3 | Terms on the **Subscription** (subscription-billed receivables) |
| 4 | **Invoice date** (same-day due when nothing else applies) |

Example: Customer *Acme GmbH* has Net 30; invoice date 1 March → due date prefills 31 March until you change it.

## 3. Manual override

1. Open the receivable in the combined invoice view.
2. Click **Due date** in the dates section (same spreadsheet-style editing as invoice date).
3. Enter a new date and commit (Enter or blur).

Your edit is kept on save. Even if customer or subscription terms change later, this invoice keeps the date you set.

## Tips and limitations

- Payment terms on the customer are **optional**; leave blank to fall through to subscription or invoice date.
- Changing customer terms does not rewrite due dates on existing drafts you already edited manually.
- Discount / Skonto terms on payables are separate; this article covers **receivable due date** prefill only.
