CartCubes Invoices for FluentCart
Create a custom invoice that is not a shop product, then copy or email a Pay Now link. The client pays in FluentCart checkout. Prices come from the invoice, not the URL.
Quick highlights
Custom invoices, not catalog products
Add one-time lines or a subscription amount for work, retainers or anything you do not sell as a shop product. The client pays through FluentCart checkout.
Pay Now with locked prices
Copy or email a Pay Now link. Quantity and price are locked on the server, so the checkout total comes from the invoice, not from the URL.
Pay Now and reminder emails
Two editable templates, send from the list or the edit screen, plus an optional automatic reminder after an invoice has been pending for a set number of days.
How it works
Search or add customer details
Search an existing FluentCart customer, or add a name and email for this invoice.
Add lines or a subscription
One-time invoices can have multiple lines. Subscription invoices use one amount, billed on a schedule, with optional trial days and a signup fee.
Save as pending and send
Copy the Pay Now link, or email it to the client. You can also save a draft first.
The client pays in FluentCart
The link opens FluentCart instant checkout. Prices come from the invoice, not the URL.
The invoice is marked paid
After payment, the invoice is marked paid and linked to the FluentCart order. You can also mark a pending invoice paid without a checkout, or cancel so the Pay Now link stops working.

Invoices
Create custom invoices with one-time lines or a subscription amount, then copy or email a Pay Now link. The client pays in FluentCart checkout.
- Invoice list: Search, filter by draft, pending, paid or cancelled, and paginate through invoices.
- One-time or subscription: Multiple one-time lines, or one subscription amount with daily through yearly billing.
- Mix store products: One-time invoices can include a store product next to custom lines on the same Pay Now link. The catalog price is used. Subscription invoices stay a custom amount.
- Trial and signup fee: Optional trial days (up to 365) and a signup fee charged at checkout. During a trial, checkout charges only the signup fee or $0 until the trial ends.
- Pay Now link: Copy, email or send a reminder. Instant checkout uses the invoice totals, not values from the URL.
- Pay Now filters: Other plugins can add query args or rewrite the Pay Now URL. Email {pay_url} and the admin Copy link stay in sync.
- Block coupons: Optionally block coupons on that invoice checkout.
- Duplicate: Copy an invoice from the list or the edit screen. The copy is a new draft.
- View order: Open the FluentCart order from a paid invoice.
- Checkout message: Optional message on that invoice Pay Now only. Place it after name and email, before payment, or in the order summary.
- Actions: View, duplicate, copy link, email, send reminder, view order, mark paid without checkout, or cancel so the Pay Now link stops working.
- Admin notes: Private notes on the invoice. The client does not see these.
Email Settings
Pay Now and Reminder email templates, with subject, heading, HTML or plain text, and merge tokens.
- Pay Now email: Send the client their Pay Now link. Enable or disable the template, then edit subject, heading, body and footer.
- Reminder email: Follow up on unpaid invoices. Use it from the list, the edit screen, or the automatic reminder.
- Merge tokens: {customer_name}, {invoice_title}, {id}, {amount}, {pay_url} and {site_name}.
- Email token filter: Other plugins can add or change invoice email tokens after the default map.
FluentCRM
Create invoices, send the Pay Now or reminder email, and cancel pending invoices from a FluentCRM automation.
- Create Invoice: Create a pending invoice for the contact. It does not send email. One-time is up to three custom lines. Subscription is one amount, with interval, trial days, and a signup fee.
- Send Invoice Email: Email the Pay Now link for a pending invoice. Choose the newest pending invoice, or one with a matching title.
- Send Reminder: Email the reminder for a pending invoice. Same target as Send Invoice Email. The Reminder template must be enabled.
- Cancel Pending Invoice: Cancel the newest pending invoice, every pending invoice with a matching title, or every pending invoice. The Pay Now link stops working.
Settings
Automatic reminders, unpaid invoices in the customer account, FluentCRM actions, and whether data is removed on uninstall.
- Automatic reminder: Send one reminder after an invoice has been pending for the number of days you set (1 through 365).
- Customer account: Show Unpaid Invoices In The Customer Account. Off by default. Pending invoices for the logged-in email, each with a Pay Now link.
- FluentCRM: Enable FluentCRM Actions. Off by default. Adds Create Invoice, Send Invoice Email, Send Reminder, and Cancel Pending Invoice to FluentCRM automations.
- Delete on uninstall: Optionally remove invoices, settings and the license record when the plugin is deleted.
