Online Invoice Payment Software
Every invoice gets a Pay Now button. Customers pay by card in seconds, the money lands in your bank, and the invoice reconciles itself.
No credit card required to start · Works on any phone
Getting paid shouldn't require a trip to the bank or a chase-down text. Costryx Pay turns every invoice into an online payment page: your customer clicks Pay Now, enters their card, and the transaction runs through Stripe straight to your account.
Because payments are wired into your invoices, reconciliation is automatic. The second a customer pays, the invoice flips to Paid, the balance updates, and you both get a receipt. No spreadsheets, no manual matching, no guessing who has settled up.
