We design and build end-to-end payment infrastructure: processing, billing, merchant dashboards, anti-fraud and bank integrations. PCI DSS and regulator compliance built in.
Storing card and payment data without PCI DSS invites fines, license revocation and loss of acquiring-bank trust.
Without scoring and anti-fraud rules, losses from fraudulent transactions, refunds and penalty fees keep growing.
Each new bank or payment-system connection turns into months of manual development and reconciliation.
OneDev builds payment systems as fault-tolerant transactional infrastructure: secure data storage, a unified processing layer, flexible billing and built-in anti-fraud. We own bank and payment-system integrations and support PCI DSS certification.
Idempotent operations, transaction consistency and horizontal scaling for peak loads.
Tokenization, encryption, network segmentation and audit — architecture designed for PCI DSS and central-bank requirements from day one.
Adapters to banks and payment systems via a common gateway: new connections plug in fast without rewriting the core.
Automated reconciliation, ledgers and reporting give a full real-time view of money flows.
Card, QR, e-wallet and P2P acceptance with authorizations, holds, refunds and partial captures.
Subscriptions, recurring payments, pricing plans, invoicing and commission calculation of any complexity.
Rules, limits, behavioral analysis and ML transaction scoring with manual review of suspicious operations.
Self-service portals for merchants and operators: transactions, payouts, reports, roles and access control.
Connectivity to acquirers, processing centers and UZ/CIS payment systems through a single gateway.
PAN tokenization, encryption, vault, logging and readiness for PCI DSS certification.
Transaction observability, payment success metrics, and alerts on failures and load anomalies.
Double-entry ledgers, settlement registers, automated bank reconciliation and accounting exports.
We map processes, regulator requirements and load, then design a secure payment architecture.
We build processing, billing and anti-fraud in iterations, with test coverage and code review.
We connect banks and payment systems and set up gateways, ledgers and automated reconciliation.
We run pentests, prepare documentation and support the certification process.
We ship to production, set up monitoring and take the system under SLA support.
Payment gateways, wallets and P2P transfers with in-house processing and anti-fraud.
Digital payment products, loan and installment billing, and core-banking integration.
Fare, parking and city-service payments via QR, cards and transit wallets.
Split payments, seller payouts, escrow and recurring subscriptions on one platform.
Collection of payments for public services, taxes and fines integrated with government registries.
Metering, recurring charges, upgrades and commission calculation for subscription products.
An MVP with basic processing and one integration usually takes 2-4 months; a full platform with billing and anti-fraud, six months and up. We refine timelines after a requirements audit.
Pricing is individual and depends on scope, number of integrations and security requirements. After the audit we provide a transparent, staged estimate.
Yes. We design the architecture to PCI DSS requirements, implement tokenization and encryption, prepare documentation and support the certifying auditor's review.
We pick by load and task: typically Java/Kotlin, Go or Node.js on the backend, PostgreSQL, Kafka, Kubernetes. We align the stack with your team and infrastructure.
With UZ and CIS acquirers and payment systems, card schemes and e-wallets. A unified gateway lets us add new connections without rewriting the core.
All source code and rights are transferred to you. After launch we offer SLA support, monitoring and product evolution, or hand the project to your team with full documentation.
