A:
Insert the UPI transaction ID into the e-invoice’s payment details section as a fixed, non-editable field.
Pull the reference ID directly from the billing ledger entry linked to the GeM purchase.
Include the purpose code/MCC only if required for internal or GeM audits, not for GST validation.
Ensure the field becomes immutable after invoice generation to maintain audit integrity.

Q:
A:
Configure the engine to map real estate token plans/charges to the correct RBI/NPCI UPI purpose code in its product/payment settings.
When generating the UPI intent/collect request, auto-attach this purpose code into the transaction metadata sent to the PSP/gateway.
Persist the tagged code on the invoice, payment record, and settlement entries, and expose it in exports/reports to simplify audits and regulatory checks.
Q:
A:
Set a retry policy with exponential backoff and a strict max retry count per UPI token transaction (e.g., 3–5 retries).
Drive throttling from p95 latency, timeout, and error-rate metrics from the gateway/UPI PSP, when thresholds breach, auto-reduce parallel calls.
Add a circuit breaker that temporarily blocks new retries, queues pending requests, and raises alerts to ops/finance until latency stabilises.
Q:
A:
When UPI caps are hit mid-checkout, the software should recommend debit/credit cards, net banking, and wallets as immediate fallback options.
It should also suggest bank transfer (IMPS/NEFT/RTGS) for high-value hospital bills.
The fallback choices must appear instantly with a clear reason for the UPI failure for user transparency
Q:
A:
Configure a retry policy with exponential backoff and a max retry cap per payment; for example, 3-5 retries per UPI transaction.
Tie throttling with latency/timeout thresholds: when the UPI/acquirer p95 latency or error rate crosses a set value, automatically lower concurrency and increase backoff.
A circuit breaker that temporarily pauses new retries, pushes pending attempts into a queued job, and raises alerts to ops/finance.
Q:
A:
The accounting package should query the mapped hospital category and current RBI/NPCI limit table in real time at payment initiation.
If eligible for higher limits, it should display a dynamic in-app and checkout banner message confirming the enhanced cap.
This message must be API-driven and audit-logged to ensure regulatory traceability.
