Invoice Management Software
See every invoice and exactly who owes you. Filter by Pending, Paid, and Overdue, send automatic reminders, and reconcile payments without lifting a finger.
No credit card required to start · Works on any phone
When invoices live in your email sent folder and a notebook, money slips through the cracks. Costryx Pay puts every invoice in one dashboard you can filter by status, so you always know what's outstanding, what's been paid, and what's gone overdue.
Clients are stored and reused, payments reconcile automatically when customers pay by card, and overdue reminders send themselves. It's the difference between hoping you got paid and knowing you did.
What you get
Status at a glance
Filter invoices by Pending, Paid, and Overdue. The dashboard shows exactly what's outstanding without any spreadsheet math.
Saved client records
Store each client once and link them to invoices. Repeat billing takes seconds and contact details never get lost.
Automatic reminders
When an invoice hits its due date, Costryx Pay emails the client a reminder for you — no awkward follow-up required.
Self-reconciling payments
When a client pays by card, the invoice flips to Paid and the balance updates instantly, keeping your records accurate.
