If an app doesn't move a metric, it doesn't belong in your stack. This guide shows exactly how to pick Shopify integrations that speed up operations, lift conversion rates and average order value, and retain customers without slowing your site or increasing costs. Built specifically for India first D2C teams.

At a Glance: What to Prioritize

Pick integrations that tie directly to a KPI like speed, conversion rate, average order value, retention, or profit margins.

Automate wherever possible including orders, returns, notifications, and payouts.

Review your stack quarterly and remove anything not used in the last 60 to 90 days.

Prefer apps with WhatsApp native flows, UPI support, and COD/RTO protections.

For growth, lock in referrals and affiliates early via Referrush because it compounds cheaply over time.

India Specific Realities: Design Around Them

Payments: UPI is the default payment method. Show rupee values, support wallets and cards, and enable smart retry logic.

Cash on Delivery: Control fraud and costs by paying incentives only after delivery. Offer a small prepaid bonus to shift the payment mix.

WhatsApp: This is the primary sharing and support channel. Use one tap shares, order updates, and reorder prompts.

Logistics: Delivery times vary across regions. Pick shipping and tracking partners with non delivery report workflows and return to origin prevention.

Compliance: Handle TDS on cash payouts and GST on invoices and discounts. Ensure apps export clean financial records.

How to Choose Apps: A Simple Scorecard

Score each potential app from 1 to 5 on these criteria. Only install apps that score 4 or higher on average.

Impact on KPIs: What does this move? Conversion rate, average order value, retention, or costs?

India Readiness: Does it support UPI, COD, WhatsApp, GST, and TDS exports?

Performance: Does it use minimal JavaScript, defer loading, use lazy loads, and server side events?

Integration: Does it have clean webhooks and APIs that work well with your email platform, CRM, and business intelligence tools?

Proof: Are there case studies in your category, a sandbox to test, and a refund policy?

Team Capacity: Does your team actually have time to use and maintain this app?

Rule of thumb: if the app doesn't earn its keep in 30 to 45 days, remove it.
