Introduction to payment gateway integration for accounting

Payment gateway integration for accounting sends clean transaction data from gateways to your books in real time, connecting platforms like Razorpay, PayU, Cashfree, Paytm, PhonePe, or Stripe to accounting systems like Tally or Zoho Books.

What is payment gateway integration for accounting

Payment gateway integration for accounting is a bridge that pulls payment events into your books, it captures orders, payments, refunds, chargebacks, fees, GST on fees, and settlements, then links each event to the right ledgers with proper tax coding and timestamps.

Key data it brings in

  • Order ID and payment ID
  • Customer name and contact
  • Product or plan details with HSN or SAC
  • Taxes like CGST, SGST, IGST
  • Fees like MDR or convenience fee with GST
  • Net settlement to bank
  • Date and time, currency, and status

This data then lands in Tally, Zoho Books, QuickBooks, or Xero with clean audit trails, you get MIS reports that match your gateway dashboard, and your CA can track exceptions and fix them early.

  • Fees accounts
    Separate MDR, convenience fees, dispute fees, and chargeback fees, record GST on fees to claim input credit.

India tax and compliance for payment gateway integration for accounting

    Gateways charge GST on fees, capture it and claim input tax credit, reconcile it with GSTR two A and vendor invoices, see, https://www.aiaccountant.com/blog/gst-compliance-services-india.
  • E invoicing for B2B
    E invoicing becomes mandatory once your B2B turnover crosses a set limit, the current common trigger is five crore, get IRN for eligible supplies like digital services.
  • GSTR one and three B
    Map HSN or SAC codes and place of supply for SaaS and e commerce, separate intra state and inter state tax correctly.
  • TDS and TCS
    TDS under section one nine four O can apply to certain aggregator models, get CA advice, track Form twenty six Q, twenty four Q challans.
  • Annual GST
    GSTR nine and nine C need clean data, for exports use LUT or IGST and keep FIRC for foreign receipts.

A good setup lowers the risk of notices and penalties, more context, https://www.aiaccountant.com/blog/payment-gateway-integration-accounting-india.

FAQs on payment gateway integration for accounting

For a startup on Tally, what is the most reliable way to ingest Razorpay or PayU data so ledgers and GST are correct

Use gateway APIs and webhooks to stream payment events into a middleware, or a connector that posts into Tally with idempotency, then apply mappings for CGST, SGST, IGST based on place of supply, AI Accountant, as an AI enabled Virtual Accounting service, can pre configure these mappings, validate sample runs, and maintain exception queues.

How should refunds, partial captures, and chargebacks be journaled so gross sales and GST remain accurate

Record gross sale on capture, for a refund, post a gross reversal of Sales and Output GST with a link to the original payment ID, for chargebacks, debit a Chargeback Provision on dispute and reverse on resolution, this keeps visibility on refunds versus disputes and sustains clean GST reporting.

We run multiple gateways and currencies, how do we avoid breakages in reconciliation at month end

Create clearing accounts per gateway and per currency, standardize order IDs across systems, revalue FX balances monthly, and implement three level reconciliation, gateway events to settlement statements to bank, AI Accountant can automate this cadence, flag breaks, and produce an audit log for your CA.

What controls should a finance head insist on before approving go live for gateway integration

Insist on idempotent posting, deduplication for retries, strict error handling and exception queues, audit logs for all changes, and maker checker for tax mappings, run a parallel trial for one cycle, reconcile differences, then approve, this reduces rework and notices.

How do we capture GST on MDR and convenience fees, and ensure ITC is claimed correctly in three B

Pull fee GST from gateway invoices or settlement statements, post to Input GST with vendor linkage, reconcile with GSTR two A, and adjust for any mismatches, AI Accountant’s workflow pairs vendor invoices to ledger entries so ITC is not missed, and supports monthly three B filing.

Is e invoicing required for B2C online sales, and what is the B2B threshold we should watch

E invoicing is not required for B2C, for B2B, once your turnover crosses the current threshold, common trigger is five crore, you must generate IRN for eligible supplies, configure your system to publish e invoices automatically for B2B customers with correct SAC and place of supply.

How do we treat coupons, cashbacks, and promotional credits in the books for an e commerce store

Treat coupons and promotional credits as marketing contra entries rather than netting sales, post gross sales, then debit Marketing Contra for the discount, this preserves true ASP metrics and keeps GST consistent, cashbacks funded by gateways should sit in fee adjustments or other income depending on terms.

As a founder, what live metrics should I monitor on the dashboard to catch issues early

Watch gateway success rate, fees as percent of GMV by gateway, refund and chargeback rates, clearing account aging, settlement TAT, GST ITC utilization, and TDS variances, AI Accountant’s dashboard surfaces these with alerts for abnormal spikes, settlement delays, or ITC leakage.

Can we post net settlements directly to revenue for simplicity, our volumes are high and the team is lean

No, posting net settlements to revenue hides fees and distorts taxes, always book gross revenue, fees, GST, and net settlement separately using clearing accounts, it improves analytics and audit readiness, and prevents GST or TDS inaccuracies.

What is the recommended cadence for reconciliations and exception handling in a fast growing SaaS

Daily exception review for failed or pending payments, weekly partial reconciliation of gateway ledgers to settlement files, monthly full reconciliation including bank, maintain an exception queue with owners and SLAs, AI Accountant can run this as a managed service, ensuring month end close is predictable.

How do we handle TDS under section one nine four O for marketplace or aggregator models

Assess your commercial flow to confirm if one nine four O applies, set up vendor wise TDS mappings, monitor gross credits and deduct TDS at source, reconcile Form twenty six Q filings, AI Accountant can design the SOP, calculate deductions, and align challans, reducing compliance friction.

We are preparing for audit, what artifacts should we have for payment gateway integration

Maintain mapping docs, SOPs, change logs, API and webhook configurations, reconciliation reports by level, gateway invoices and settlement statements, GST and TDS filings, and exception closure logs, AI Accountant packages these in an audit binder so your CA and auditor have a complete trail.
