Invoices are emailed from Anytime Capital in your branding and paid at their url. Totals are calculated from the line items, an optional discount and tax. A customer can pay a deposit first, and automatic reminders go out around the due date unless you turn them off.

}Knowing when an invoice is paid
Subscribe to the invoice.paid webhook, which carries the invoice object once it is paid in full, by card or recorded as paid in the dashboard. Each card payment on an invoice, deposits included, also sends payment.succeeded with source.type invoice and source.id the invoice id. See Webhooks.
