I will develop a white label payment gateway and payment processor
ranjanaurmaliya
About this gig
Need your own payment infrastructure instead of renting someone else's?
I build custom white label payment gateways and full PSP platforms: processing, dashboards and the APIs that connect them to your acquirers.
WHAT I BUILD
- White label payment gateway with your branding
- Full PSP platform: merchant onboarding to settlement
- 3D Secure 2 (EMV 3DS) authentication flows
- Multi-acquirer routing with automatic failover
- Crypto processing: BTC, ETH, USDT, on-chain settlement
- Merchant dashboard: transactions, refunds, payouts, reports
- Admin panel: risk rules, fees, rolling reserve, MIDs
- REST API, webhooks and developer docs
- Tokenization, encryption, PCI DSS aligned design
- Chargeback and dispute handling workflows
HOW I WORK
- Architecture and scope agreed before any code
- Modular design that scales with your volume
- Clean code built to pass acquirer technical review
- Deployment and handover included
WHO IT'S FOR
Licensed PSPs, ISOs, fintech startups and merchants with an existing acquiring relationship. I build the software; licensing and PCI certification stay with you.
Message me your acquirer, markets and volume for an architecture proposal and exact quote.

FAQ
Do I need a licence or an acquiring relationship to use this?
Yes, to process live card payments. I build the technology; you need the acquiring bank, PSP licence, or sponsorship for your jurisdiction. Tell me what you have and I'll build to their technical requirements.
Can the platform scale as my transaction volume grows?
Yes. The architecture is modular, so you can add acquirers, currencies, payment methods and merchants without a rebuild. Processing services scale horizontally, and I load test against your projected volume before handover so you know where the limits are.
Do you support non-3DS / MOTO transactions?
Non-3DS flows exist for specific legitimate cases like MOTO and recurring billing, and I can implement them where your acquirer permits it. I only build these for clients with a real acquiring agreement that allows it — I don't build systems designed to bypass cardholder authentication.
Is the system PCI DSS certified?
I build to PCI DSS aligned architecture — tokenization, encryption, network segmentation, no raw PAN storage. Certification itself is an audit you complete with a QSA; I'll prepare the system and documentation for it.
Which acquirers and processors can you integrate?
Most that expose an API — Stripe, Adyen, Checkout.com, Nuvei, Worldpay, PayU, and regional acquirers. Send me their integration docs and I'll confirm before you order.
Which cryptocurrencies do you support?
BTC, ETH, USDT, USDC and most EVM chains, with on-chain confirmation handling, automatic conversion, and wallet management.
