Enterprise Payment Gateway - Fixed USD Milestones

Build resilient, multi-processor payment checkout architectures that eliminate payment failures and protect customer financial data. Aurevon engineers custom Stripe, Adyen, and ACH payment gateways on AWS us-east-1 under fixed USD milestone contracts.

Production Architecture

Fintech platforms, high-volume recurring subscription businesses, and enterprise e-commerce merchants processing over $1M in monthly transactional volume.

Who Is It For

Fintech platforms, high-volume recurring subscription businesses, and enterprise e-commerce merchants processing over $1M in monthly transactional volume.

Typical US Use Case

A San Francisco B2B SaaS billing engine suffered a 6.2% payment decline rate during subscription renewals. We re-engineered their billing middleware with intelligent routing across Stripe and Adyen, configured automated card updater webhooks, and integrated direct Plaid ACH debit, lowering transaction fees by 34% and recovering $280,000 in monthly recurring revenue.

Enterprise Security

Engineered for high-concurrency US traffic surges, low-latency nationwide delivery, and resilient cloud uptime.

Compliance & Tech Considerations

Engineered to PCI-DSS Level 1 standards using client-side tokenization (Stripe Elements / Adyen Drop-in) ensuring zero raw cardholder data touches your application servers. Automated network tokenization, 3D Secure 2.2 authentication, and AWS us-east-1 KMS encryption.

Production Scale & Quantified Outcomes

Defensive data security protocols coupled with verified business results.

Verified Production Outcomes

Reduced payment decline rates from 6.2% to 1.1%, decreased merchant processing fees by 34% via optimized ACH routing, and achieved complete PCI-DSS SAQ A compliance.

Verified Engineering Standards

Every milestone is governed by a fixed USD Statement of Work, unencumbered intellectual property assignment under US law, automated CI/CD suites, and weekly Friday staging deployments.

AWS US Multi-Region (us-east-1 & us-west-2) & SOC 2 Type II

Every platform is deployed with verified domestic US cloud hosting, automated CI/CD coverage, and strict compliance with SOC 2, HIPAA, and CCPA standards.

100% US Commercial IP Assignment & Fixed USD Milestone Quotes

Full Git repository ownership and commercial copyright transferred under US law with milestone disbursements in USD ($) via ACH or wire and zero retainers.

Frequently Asked Questions (United States)

Direct answers to questions US founders and engineering directors ask us before getting started.

How do you ensure our servers remain outside the scope of heavy PCI-DSS audits?+

We implement client-side hosted tokenization and secure iFrames, ensuring sensitive primary account numbers (PAN) never touch your backend infrastructure, qualifying your business for lightweight SAQ A compliance.

Can you integrate Plaid ACH payment processing alongside credit cards?+

Yes. We build unified checkouts that offer instantaneous Plaid bank account verification and low-fee domestic ACH debit alongside credit and debit cards, cutting payment processing overhead on large transactions.

How does intelligent multi-processor failover work?+

If an outage or elevated fraud decline occurs on your primary payment processor, our routing middleware seamlessly dispatches subsequent transaction requests to an active secondary gateway without customer friction.

How do your fintech engineers collaborate with US technical teams during development?+

We provide real-time collaboration across Eastern, Central, Mountain, and Pacific timezones, coordinating via Slack, holding daily standups, and providing live sandbox testing sessions.

Do we own the custom billing engine and integration source code?+

Yes. All integration repositories, cloud infrastructure scripts, and webhook orchestrators are transferred directly to your corporate custody with complete unencumbered IP assignment under US law.

What tax paperwork and payment methods do you accept from US enterprises?+

We issue formal W-9 forms, provide fixed USD milestone billing, and receive payment via domestic ACH bank transfers, Fedwire, and Net-30 enterprise invoicing.
