How should reconciliation software export UPI reference IDs for term deposit opening into our GST e-invoice PDF?

If your SaaS invoicing tool handles UPI payments for term deposit (FD) openings, you really need to monitor daily UPI inflows, both for compliance and to avoid hitting PSP caps.

It’s not about tracking each payment, it’s about spotting when total UPI volume or value starts spiking.

Here’s what to set up:

• Daily Aggregate Value Alert

Trigger an alert when total UPI receipts for term deposits cross a set threshold (say ₹50 L or ₹1 Cr per day).

Why:

Banks and PSPs impose soft caps on total daily inflows for high-value UPI handles. Crossing that cap could delay settlements or block new payments.

• Transaction Volume Spike Alert

Set a rule for when total number of UPI transactions jumps by, say, 30–50% vs. average.

Why:

A sudden increase could mean automation bugs (duplicate posting) or customer retries due to PSP failures.

• High-Value Receipt Alert

Alert on any single UPI payment above ₹1.5L–₹2L.

Why:

UPI caps vary by bank, and if you’re receiving unusually large payments, that’s worth a quick check before settlement files bounce.

• Pending Settlement Alert

Every day, compare UPI Success count vs. UPI Settled count from NPCI files.

Alert if pending settlements > 5% of daily volume.

Why:

That usually means a mismatch in your ledger or delayed RRN posting.

• Partner-Wise Cap Tracker

Track UPI usage per partner bank or VPA (e.g., icicibank@upi, hdfcbank@upi).

Alert if:

Total inflows for any partner > 80% of their assigned daily limit.
That gives ops teams time to route new deposits via another partner.

• Reversal or Refund Spike Alert

Monitor sudden increases in reversed or refunded RRNs.

Why:

Could mean failed FD creations, PSP instability, or a problem with split payments.

• UPI Failure Rate Alert

If failure rate (failed RRNs ÷ total attempts) exceeds 10–15% in a day, alert finance + tech teams.

Why:

Might indicate PSP downtime or broken UPI intents.

If your POS (like a school’s front-desk billing or fee collection terminal) accepts UPI payments, you absolutely need to push the UPI Reference ID (RRN or UPI Txn ID) into the GST e-invoice PDF, both for audit and GST return matching.

Here’s the clean way to do it:

• Capture the right UPI field from the PSP

Every successful UPI payment response contains a unique reference ID, usually under one of these keys depending on your PSP:

upi_txn_id: 231015672345,

rrn: 324512378912,

txn_reference: HDFC12345UPI

Make sure your POS stores this value in your payment table alongside the invoice number, like:

invoice_no | payment_mode | upi_ref_id

FE2025-0923 | UPI | 231015672345

• Map it into the e-invoice JSON schema

The GST e-invoice format already has a section for Payment Details:

PaymentDet: {

PayMode: UPI,

FinInsBr: HDFC Bank,

PayInstr: 231015672345,

PayTerm: Full,

PayInstrDt: 2025-10-28

}

Here, PayInstr is where your UPI reference ID goes — that’s the field most ERP and GST tools recognize when generating the final PDF.

• Modify your PDF template

If your POS auto-generates PDFs, just add a small Payment Reference block under the payment summary section:

Payment Mode: UPI

Reference ID: 231015672345

Bank: HDFC Bank

That’s all GST auditors need to trace the UPI transaction back through NPCI or the PSP.

• Validate before export

Always check that:

• The UPI ID is alphanumeric and 12–20 chars long
• The transaction status = SUCCESS
• It’s linked to the same invoice date

This avoids junk data creeping into e-invoices or IRN rejections during filing.

• Sync with your accounting / ERP

When you push invoices to Tally, Zoho Books, or your ERP, include the same upi_ref_id field in your payment ledger. That keeps reconciliation super easy later, especially when you pull settlement reports from Razorpay, Cashfree, etc.

If your reconciliation tool is handling UPI collections for term deposit openings (FDs), you really want those payments tagged with the right purpose code — otherwise, your audit trail turns into spaghetti.

Here’s how to do it without overcomplicating your system:

• Add a purpose code field to every incoming UPI transaction

When your system parses PSP or NPCI settlement files, include a column for purpose codes.

If you’re generating the UPI collect request yourself, you can also tag it in the payload (many gateways support this).

Example:

purpose_code: TDOP

Here, TDOP = Term Deposit Opening Payment.

• Maintain a small internal mapping table

Keep a lookup that maps product categories → purpose codes.

When reconciliation runs, match the incoming payment to the category (based on metadata or account it hit) and auto-assign the right code.

• Write it into your ledger and export files

In your ledger entries, include the purpose code as a column or tag.

This lets auditors filter only FD-related receipts instantly.

• Push the code to your GST and accounting exports

When your reconciliation tool pushes data to your accounting package or GST e-invoice system, include the purpose code as part of the Payment

Details section:

Payment Mode: UPI

Purpose Code: TDOP (Term Deposit Opening)

UPI Ref ID: 324915674382

That gives traceability from PSP → ledger → GST filing.

• Validate the tagging logic

If your reconciliation logic ever sees a UPI payment hit a Term Deposit account but no purpose code attached — flag it.

This catches untagged or misrouted collections early.

To test refunds and chargebacks for FD openings under new UPI caps:

• Simulate pre- and post-settlement refunds.
• Verify RRNs are linked correctly.
• Ensure refunds don’t count as inflows.
• Test refund behavior when PSP/bank caps are hit.
• Always reconcile with NPCI files (R-17, R-19, R-22).
