Stop Losing Sales to Broken Checkout and Payment Failures
I set up and configure payment gateways (Stripe, Razorpay, PayPal) for businesses that need reliable transactions, tax compliance, recurring billing, and multi-currency support. You get a checkout that works on the first try, not one that sends customers to your competitor.
Every Failed Payment Is a Customer You Already Convinced and Then Lost
I've debugged payment flows where 8-12% of transactions were silently failing. The checkout looked fine. The Stripe dashboard told a different story. Expired webhook endpoints, missing error handling, and untested edge cases (currency conversion, 3D Secure, declined retries) are the usual culprits.
Silent failures Payments fail but your system shows success. Customers don't get what they paid for. Refund requests pile up.
Redirecting users to a third-party payment page adds friction. Each redirect loses 10-15% of buyers.
Currency confusion International customers see prices in the wrong currency or get hit with unexpected conversion fees at checkout.

How I Work
Audit
I review your current payment flow, transaction volume, currencies, and compliance requirements. You'll know what's broken and what's missing.
Configure
I set up the gateway, webhook endpoints, and test transactions across all payment methods you need. Every edge case gets tested.
Integrate
I wire the gateway into your checkout with proper error handling, retry logic, and customer-facing failure messages that don't say 'error 500.'
Verify
I run 50+ test transactions covering success, failure, refund, subscription renewal, and currency conversion scenarios before go-live.

Common questions
Which payment gateway should I pick?
India: Razorpay (best UX), PayU (best routing), Cashfree (best for high-risk and recurring). Global: Stripe (best dev experience, broadest coverage), Paddle (merchant-of-record so you skip VAT/MOSS yourself), PayPal (still mandatory for trust). Most stores need 2–3 gateways: a primary, a fallback, and a regional option.
Do I need a Merchant of Record (MoR) like Paddle or Lemonsqueezy?
If you sell digital products globally and don’t want to handle EU VAT, GST on services, US sales tax, and IOSS yourself: yes. Paddle takes 5%+, but the alternative is a tax accountant per region or a chronic compliance gap. For physical-goods stores, MoR isn’t worth it; standard payment gateways are fine.
How does UPI payment work for WordPress stores?
UPI is added via Razorpay or Cashfree, which expose UPI as a checkout option alongside cards/netbanking. UPI Intent flow opens the user’s chosen UPI app (PhonePe, Paytm, GPay) and completes payment in 5–10 seconds. Conversion is typically 30–50% higher than card-only checkout in India.
Can you set up subscriptions and recurring billing?
Yes. Stripe Subscriptions (best globally), Razorpay Subscriptions (best in India, with eMandate for UPI autopay), PayPal Subscriptions, or custom solutions via WooCommerce Subscriptions, FluentCart, or SureCart. Each handles dunning (failed payment retries) and proration differently — I’ll pick based on your billing model.
What about webhooks, refunds, and reconciliation?
Configured on every project. Webhooks fire on payment success, failure, refund, dispute, subscription cancel, and chargeback. WordPress order status updates in real time. Daily reconciliation report exported to your accounting system (Xero, Zoho Books, QuickBooks, Tally) so finance can match orders to settlements without manual work.
Can you fix a broken payment integration?
Yes. Common breakages I fix: webhooks pointing to wrong URLs, race conditions on order status, refunds not flowing back into WordPress, mismatched currency conversions, and SCA (Strong Customer Authentication) failing on European cards. Audit + fix is usually a 1-week project.
BNPL (Buy Now, Pay Later) — should I add it?
For ecommerce with average order value above $100/₹5,000: yes. Klarna, Afterpay, Affirm internationally; LazyPay and Simpl in India. AOV typically jumps 30–60% on stores that add BNPL because customers anchor on the installment amount, not the total. Set-up cost is mostly time, not money.
Pricing?
Single gateway setup: $499. Multi-gateway with subscriptions, webhooks, and reconciliation: $1,499. Audit + fix on existing integration: $799. Custom flows (multi-currency, multi-vendor, custom checkout): scoped per build.
