Payments with PayU
PayU is a long-established gateway with strong EMI and affordability options, useful for higher-value purchases. We integrate PayU checkout into your website or app with correct hash generation and verification, refunds, recurring payments and callbacks.
What this covers
Typical timeline
A standard gateway integration takes 1–3 weeks; payout, BBPS or AEPS platforms are delivered in phases.
Who it is for
PayU requests and responses are protected with a SHA-512 hash that must be generated and verified on your server. We implement this correctly, handle success and failure callbacks alongside server-to-server notifications, and reconcile settlements.

Engagement models
A discovery workshop produces a written scope, architecture and milestone plan with a fixed price before any build commitment.
A cross-functional squad (PM, engineers, QA, DevOps) working in two-week sprints on your roadmap, billed monthly.
SLA-backed maintenance, security patching and a monthly allocation of enhancement hours after go-live.
How pricing works: Integrations are quoted per gateway and flow (checkout, subscriptions, refunds, payouts, split settlements). Gateway transaction fees are agreed directly between you and the provider.
