Configuring a VPS order: billing cycle, options and the order summary

What happens to a renewal

PNLCS runs billing on a schedule, so nobody has to remember to send an invoice or switch off an unpaid account. These are the defaults; every number is a setting.

Billing lifecycle in the docs

  1. 14 days before

    Renewal invoice

    Created and emailed to the customer.

    invoice_days_before_due = 14

  2. 3 days before

    Stored card charged

    If you turn auto-charge on. Up to 3 attempts, 3 days apart.

    AutoChargeDaysBefore = 3

  3. Due date

    Reminders

    Unpaid invoices turn overdue and reminder emails go out. An optional late fee applies after 3 days.

    LateFeeMinDays = 3

  4. 3 days after

    Suspended

    The service is suspended on the server. Paying unsuspends it within 30 minutes.

    AutoSuspensionDays = 3

  5. 30 days after

    Terminated

    Only if you enable it. Off by default.

    AutoTerminationDays = 30
