# Overdue invoices

> What happens when an invoice isn't paid on time.

An invoice becomes overdue when it passes its due date without being paid in full. Clarely flags overdue invoices in your list so nothing slips through.

## How overdue is determined

The due date is calculated from the **net terms** on the invoice. The default is **net 14** (14 days from the invoice send date). You can change your default net terms in **Settings → Invoicing**, and you can also set a custom due date on any individual invoice before sending.

Clarely computes overdue status in real time — there's no overnight batch. An invoice shows as overdue as soon as its due date passes with a remaining balance.

## Finding overdue invoices

Overdue invoices are flagged in your invoice list. Filter by status to see all overdue invoices at once.

## Late fee preview

If you've configured a late fee in your invoicing settings, Clarely shows a late fee preview on overdue invoices. This is informational — the late fee is not automatically added to the invoice total or sent to the client. How you apply it is up to you.

## Following up

Clarely can send automatic payment reminders before and after the due date. Configure reminder timing in **Settings → Workflow**. See [Invoice reminders](/invoices/invoice-reminders) for the full setup. Reminders stop automatically once the invoice is paid.

To follow up manually, open the invoice and tap **Resend** to send another email to the client with the payment link.

## Marking an overdue invoice paid

If a client pays late (or pays outside Clarely), mark the invoice paid manually. Open the invoice and tap **Mark as Paid**. Enter the amount received. If they paid the full balance, the invoice moves to **Paid** status. If they paid partially, the remaining balance stays visible and the invoice remains in your active list.

<Tip>
  Checking your invoice list at the end of each week is the easiest way to catch overdue invoices before they age too long. With payment reminders set up, Clarely handles most of the follow-up automatically.
