How do I send an invoice with PayPal?

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.

Check the bill’s hospital/healthcare MCC or purpose code and confirm the hospital is NPCI-verified for high-value UPI.

Validate the payable amount against the applicable per-transaction and daily caps before showing eligibility.

Confirm via the gateway/PSP pre-auth response that the high-limit category is accepted.

Show a higher-limit eligible banner only after all checks pass and log the validation for audit.

Use a purpose-code mapper that assigns the correct automotive/vehicle MCC based on the product (car, bike, commercial vehicle).

Embed this purpose code in the UPI collect/debit payload so the gateway logs it correctly.

Store the purpose code + UPI txn ID in the reconciliation ledger for audit and settlement matching.

Block UPI initiation if a down payment lacks a mapped purpose code

Use purpose-code/MCC-driven GL mapping so vehicle down-payment UPI receipts post to the correct vehicle sales, deposit/escrow, tax and fee ledgers.

Add split-settlement rules to allocate down payment across dealer settlement, taxes, dealer commissions, and platform fees with parent→child UPI txn links.

Enforce NPCI/bank per-txn (₹5L) and daily (₹10L) cap checks before posting and flag over-limit receipts for manual review or auto-split.

Persist immutable UPI txn ID, purpose code, merchant verification flag, and parent/child links on every ledger entry to support reconciliation, refunds and audits.

Integrate the ERP finance module with the PSP/NPCI UPI limit-eligibility API and tag each payment as EVENT_TICKETING before the check.

If the API returns higher-limit support for the customer’s bank, show a banner like Your bank supports higher UPI limits for ticket purchases,  up to ₹X available.

Cache eligibility results per bank for a few hours and fall back to standard-limit messaging when no enhanced limit is returned.
