Payment Processing & Application Security

Security-Conscious Development
Applications handling customer, account, and payment information require security to be part of the development process rather than an afterthought. Our work has included SSL/TLS configuration, access controls, encrypted credentials, secure sessions, form validation, injection prevention, cross-site scripting protections, restricted administrative areas, and PCI-related application changes.
We have also worked through security scan findings and compliance-related remediation in existing applications, where the goal is to correct actual vulnerabilities without unnecessarily breaking required application behavior.

Payments That Connect With the Application
- Authorize.net integrations, including customer profiles and recurring billing
- Stripe integrations and token-based payment processing
- PayPal integrations
- Secure standalone payment portals
- Customer payment profiles for repeat transactions
- Recurring and scheduled payments
- Customer transaction history and receipts
- Declined-payment and expiring-payment-method reporting
- Financial-system exports and transaction synchronization

Payment Processing
We have implemented payment processing within eCommerce, reservation, subscription, point-of-sale, and standalone payment applications. Our experience includes one-time payments, saved customer payment profiles, recurring billing, deposits, partial payments, refunds, and administrative payment processing.
Payment functionality has also been integrated with customer accounts, orders, invoices, reservations, and transaction histories, allowing payment activity to become part of the larger application workflow rather than an isolated checkout process. This includes handling payment status, receipts, declined transactions, refunds, and other information needed by both customers and administrative staff.
