Payment troubleshooting

Customers can’t pay?

Checkout errors lose sales. Payments that succeed without creating an order leave a different mess. I trace what happened between the customer, the payment provider and your application.

A missing order does not mean the payment failed

Before asking a customer to pay again, check whether the provider accepted the original payment. The application may have missed the confirmation or failed while saving the order.

Fix the checkout—and account for the affected orders

Restoring new payments is only part of the work. I also look at which orders are missing, delayed or duplicated so that retries do not create a second charge or a second order.

  • Checkout errors before payment completes
  • A successful charge with no matching order
  • Payment notifications that arrive late or are processed twice
Payment integration details I can investigate
  • Gateway requests, authentication and environment configuration
  • Webhook delivery, signature verification and event processing
  • Order writes, retries and duplicate-prevention logic
  • Matching provider events to application records using redacted identifiers—not card numbers
What if the payment provider itself is having an outage?

I can check whether the failure is in your application or upstream. I cannot restore the provider’s service. NWI Software Rescue is independent, not payment-provider support.

What happens when a customer pays?

Tell me whether checkout fails, the payment goes through without an order, or something else happens.
