The Sterling difference
Oversight, engineered in.
Nothing moves on its own. Every transaction passes through a deliberate, four-step path — the reason platforms trust us with real money.
Integrate
Drop in the API. Create a payin or payout with a single signed request.
Queued
The request lands in a unified approval queue — never auto-settled.
Reviewed
An admin approves or rejects, with reason. The ledger moves only then.
Notified
A signed webhook fires; your platform reflects the result instantly.
Capabilities
Everything a modern money platform needs.
Fast local transfers
Quick, secure disbursement to local bank accounts and UPI IDs — single or in bulk.
Dynamic UPI collections
Generate a unique per-transaction QR encoding amount + reference. The payer scans, pays, enters the UTR.
Human-approved settlement
A person reviews every payin and payout. Approve, reject with reason, or bulk-clear a batch.
HMAC everywhere
Signed API requests and signed webhooks. Secrets are shown once, never re-displayed.
Real-time dashboard
Wallet, statements, and live status updates the moment an admin acts — no refresh.
Full audit trail
An append-only ledger reconstructs every balance. Nothing is silently mutated.
Security & compliance
Every transaction reviewed before it settles.
Manual approval isn't friction — it's the control layer. Fraud gets stopped by a person, not a heuristic, and every decision is signed, logged, and reversible in the ledger.

Payins
A dynamic QR for every payment.
Call the API and we mint a unique UPI QR encoding the exact amount and reference. Your customer scans, pays in any UPI app, and enters the UTR on a hosted page that feels like part of your brand.
- Unique per-transaction QR + intent link
- Hosted, on-brand checkout page
- PSP status as a second signal against fraud
Amount payable

Payouts
Three ways to disburse.
Single transfer
Fire one payout via the API or the admin — reviewed, then executed.
Bulk transfer
Upload an Excel of many rows. We validate each, flag the bad, queue the good.
API-triggered
Your end-user requests a withdrawal; your backend calls us; we queue it for review.
The dashboard
Clarity your finance team will love.

FAQ
Quick answers.
Every payin and payout lands in a unified queue. An admin (or a scoped sub-admin) approves or rejects it — the ledger only moves on approval, and a signed webhook notifies you instantly.
Approvals are typically actioned within minutes during business hours. Bulk batches can be cleared in a single action.
Dynamic UPI collections for payins; single, bulk (Excel) and API-triggered payouts to bank accounts or UPI IDs.
Yes. Every account starts in sandbox so you can integrate and test the full flow before switching to live.
Webhooks are signed with HMAC-SHA256 using your webhook secret; money-movement API calls require a signed request within a replay window. Secrets are shown once.
