Overview
If your subscription has an outstanding invoice, you can pay it in the Account Center to bring your account current and restore access. This guide shows you how to find the invoice and complete payment, including adding a card if you do not have one on file. Payment is available to Billing Owners. This guide also covers downloading invoices and receipts, adding a PO number, correcting invoice details, and tax-exempt orders.
Step 1: Open your purchases
Sign in to the Account Center at lucensoftware.com with your Billing Owner credentials. From the left menu, go to Admin, then Purchases.
Step 2: Find the invoice
Locate the invoice you need to pay. To find it quickly, use the Status dropdown to filter by Payment Due, or search by invoice ID.
Step 3: Open the invoice
Click the arrow on the invoice row to open the invoice details, where you can review the amount due and status.
Step 4: Pay the invoice
Click Pay. Choose your saved card, or select Pay with a new card and enter your card details, then complete payment. You receive an email confirmation once the invoice is paid.
For help adding a card, see Managing your saved payment methods in Account Center.
Download or email a copy of your invoice
Open the invoice from Purchases as above, then choose Download PDF to save a copy, or Send invoice to email to have it emailed. If you cannot find an invoice, contact support with any one of these: your subscription reference, the invoice or order number, the last four digits of the card, or the charge date.
My "pay now" link expired
Sign in and pay from Purchases as shown above. The emailed link is only a shortcut; the invoice is always payable from the portal.
Add a PO number or correct invoice details
You can add a PO number during purchase, at checkout. It then appears in the PO number column of your Purchase history and on the invoice. If an invoice was already issued without a PO, or the company name, address, or VAT number is wrong, contact support with the invoice number and the correct details, and we will re-issue the invoice PDF. If you bought through a reseller, the PO is held by the reseller.
Tax-exempt organizations
Send your tax-exempt certificate to [email protected] before you purchase, and we will flag the account so tax is not applied to future orders.
If tax was charged on an invoice you already paid, we cannot refund the tax portion alone. We can refund the full invoice and re-issue it without tax.
The invoice is paid but the portal says "Expired"
This usually means the original subscription was cancelled and replaced with a new one under a different subscription reference. Check Subscriptions for a second entry. If you only see the expired one, contact support with the invoice number.
Invoice period of performance
If your organization needs the service period to start on a future date, contact support before paying and we will re-issue with the dates you need.
The payment form will not load
If the card form stays on "Loading secure card form," clear your cache and cookies, or use a private window in Chrome or Edge. If it still fails, send support a screenshot.
Removing a saved card
