Stop Losing Orders At The Payment Step

Shopify payment gateway integration means connecting one or more payment processors, such as Razorpay, PayU, Cashfree, Stripe or PayPal, to your store through Shopify's supported Payments Apps API and checkout extensibility. It also covers local payment methods, fraud rules and settlement reconciliation, not just switching on a single default gateway. The work that actually affects revenue is usually downstream of the connection: which gateway handles which transaction, what happens when one declines, and whether settlements reconcile against orders without a spreadsheet. We scope those explicitly, because an integration that only proves a test payment succeeds is not finished.

Most new stores are fine with one gateway. A second starts paying for itself once decline rates, gateway downtime or a missing local payment method are measurably costing you orders, typically once a store is processing meaningful volume across several regions. Before adding one we look at your actual decline data, because another processor means more fees, more reconciliation and another integration to maintain. If declines are really caused by fraud rules that are too strict, or by a checkout losing people earlier, a second gateway fixes nothing. We will tell you which of the two you are facing.

Yes. We integrate these and other regional gateways alongside Shopify Payments, with routing rules that decide which gateway handles a given transaction based on card network, region and order value. Each gateway is connected through Shopify's supported payments app path rather than an unsupported checkout hack, so it survives platform updates. We also test the parts merchants tend to discover late: refunds and partial refunds, currency handling, webhook reliability, and how each provider reports settlement. Availability of specific methods depends on your acquiring setup and the gateway's own onboarding, which is their approval process rather than something we can shortcut.

Smart payment routing sends each transaction to the gateway most likely to approve it, based on factors like card issuer, region and order value, instead of pushing every transaction through one fixed processor. Done properly it also handles failover, so a gateway outage during a sale does not stop orders. The honest caveat is that routing only helps when you have enough volume for the differences between providers to be real rather than noise. We start by measuring approval rates per gateway on your own traffic, then write the rules from that data instead of from vendor marketing claims.

Yes. We add UPI, popular wallets and BNPL providers such as Simpl, LazyPay, Klarna or Afterpay through your connected gateways, so customers see the local payment methods they actually use. This is one of the higher-return changes available in checkout, since Baymard's research puts average cart abandonment at 70.19%, with a missing or unwanted payment option a recurring reason buyers leave. What we cannot do is enable a provider you are not approved for, because each has its own underwriting, category restrictions and fees. We map which providers fit your business and market before promising anything at checkout.

We build retry sequences and card updater logic on top of the Selling Plans API and your gateway's tokenization, so a declined renewal gets a second and third attempt on a schedule instead of silently cancelling the subscription. Retries are paired with customer messaging, because a genuinely expired card needs the customer to act, and dunning emails recover more revenue than retry logic alone. Every attempt is logged so you can see real recovery rates rather than guessing. Retry schedules also have to respect card scheme rules, so we keep them within those limits instead of hammering the gateway.

We layer velocity checks, device signals and address verification on top of your gateways' built-in fraud tools, tuned to your specific order profile so legitimate customers are not blocked while suspicious orders get flagged before capture. The tuning is the actual work. Rules that are too aggressive cost more in rejected good orders than the fraud they prevent, so we measure both sides and revisit the thresholds with real data after launch. For higher-risk categories we prefer a narrow manual review queue over blanket blocking. No setup eliminates chargebacks, so the goal is a defensible ratio rather than zero.

Yes. We build a webhook-driven matching layer that reconciles gateway settlement files against Shopify orders automatically, including partial refunds and multi-currency settlements that a manual spreadsheet process usually gets wrong. Unmatched items are surfaced in a report for a human rather than quietly written off, which is the difference between reconciliation and hopeful arithmetic. Where your finance team uses an ERP or accounting system, we push matched settlements into it instead of asking them to re-enter data. Timing depends on each gateway's settlement schedule and file format, so both get confirmed during discovery before the work is quoted.

Card data stays inside your payment gateways' hosted fields and tokenization flows. Our integration code never touches raw card numbers, which keeps your PCI DSS scope the same as using a certified gateway directly. That is a deliberate architectural choice rather than a convenience: the moment an integration handles card data itself, your compliance burden and breach exposure change completely. API credentials live in your own accounts and secret storage, never embedded in theme code. If a requirement would expand your PCI scope, we say so and propose an alternative that keeps sensitive data with the processor where it belongs.

A single additional gateway with basic routing typically takes 1 to 3 weeks. A full multi-gateway setup with fraud rules, recurring billing and reconciliation automation usually takes 4 to 6 weeks, depending on how many payment methods and markets are involved. The delay in practice is rarely development time; it is gateway onboarding, merchant account approval and sandbox credentials, all of which sit with the provider. We raise the paperwork and access requests on day one for that reason, and we sequence launches so the store keeps taking payments throughout rather than needing a risky cutover window.

Yes, using Shopify Markets alongside locally acquiring gateways, so international customers see pricing and payment methods that feel native to their market instead of one foreign-currency checkout. Local acquiring usually improves approval rates, and showing prices in local currency with duties handled upfront reduces exactly the surprise costs Baymard's research identifies as the leading reason people abandon a cart. The constraints here are commercial rather than technical: each market needs an acquiring relationship, and duty and tax handling has to match your legal setup. We work through that with your finance team before configuring anything.

Yes. Gateway APIs, fee structures and fraud rules change over time, so we monitor approval rates and settlement accuracy after launch and adjust routing and rules as your transaction data grows. Payments are the part of a store where silent failure is most expensive, because a broken webhook or an expired credential can stop orders without any visible error on the storefront. Alerting is therefore part of the build rather than an add-on. We also review the setup ahead of peak trading periods, when a gateway limit or an outgrown fraud rule is most likely to bite.
