Opeux Invoices is for the small business that hates chasing money. Send polite, on-brand reminders on a schedule that suits you, see what's overdue at a glance, and stop letting unpaid invoices quietly bleed your cash flow. It is not a full accounting package — it sits next to your accounting tool and handles the bit it does badly: gentle, persistent follow-up. AI drafts the reminder copy, you approve, and the invoice gets paid weeks earlier. Reminders include a clean public link to the invoice so customers see exactly what's outstanding without trawling their inbox for the original PDF, and you can track every open and download on the activity log.
