Beyond Standard Checkout

Most checkout solutions offer a fixed flow. GoKwik stands out by allowing custom checkout flows tailored to your specific business model. Whether you sell subscriptions, bundles, or B2B — the checkout adapts.

When You Need Custom Checkout Flows

Subscription Products

Standard checkout doesn't handle recurring orders well. Custom flows let you:
  • Show subscription frequency options (weekly, monthly, quarterly)
  • Display savings comparison (one-time vs subscription)
  • Set up auto-renewal with payment tokenization
  • Allow pause/resume from the checkout itself

Bundle Products

Selling product bundles requires special handling:
  • Dynamic pricing based on bundle composition
  • "Build Your Box" interface within checkout
  • Quantity adjustments per item in the bundle
  • Gift wrapping and messaging options

B2B / Wholesale Orders

B2B customers have different needs:
  • Bulk quantity inputs with tiered pricing
  • GST number collection and validation
  • Purchase order reference fields
  • Net payment terms (Net 30, Net 60)
  • Multiple shipping addresses per order

Pre-Orders & Launches

Product drops and pre-orders need urgency:
  • Countdown timers in checkout
  • Expected delivery date display
  • Partial payment / deposit options
  • Waitlist to checkout conversion

Building Custom Flows with GoKwik

The GoKwik Checkout SDK

GoKwik provides APIs and SDKs to customize: Checkout UI Customization:
  • Custom fields (engraving text, gift messages)
  • Conditional sections (show/hide based on product type)
  • Custom validation rules
  • Branded themes with CSS overrides
Business Logic Customization:
  • Dynamic shipping rates based on cart contents
  • Custom discount logic (loyalty points, referral codes)
  • Order splitting for multi-vendor marketplaces
  • Inventory-based fulfillment routing

Integration Architecture

The typical custom GoKwik integration looks like:

1. Frontend: GoKwik Checkout SDK embedded in your Shopify theme 2. Middleware: Your custom API for business logic (Node.js/Python) 3. Backend: Shopify Admin API for order creation 4. Webhooks: Real-time order status sync between GoKwik and Shopify

API Endpoints You'll Use

  • Cart API: Modify cart contents programmatically
  • Checkout API: Create and update checkout sessions
  • Payment API: Custom payment flow handling
  • Shipping API: Dynamic rate calculation
  • Discount API: Apply custom discounts

Real-World Implementation

Case: Fashion Brand with Size Exchange at Checkout

We built a custom flow for a fashion client where:
  • Customers could select "Unsure about size?" at checkout
  • A size recommendation quiz appeared inline
  • If they opted for "Easy Exchange", a prepaid return label was auto-generated
  • This reduced size-related returns by 28%

Case: Supplement Brand with Subscription Upsell

For a health supplement brand:
  • One-time purchase was default
  • "Subscribe & Save 15%" toggle at checkout
  • Subscription frequency selector appeared on toggle
  • Customers could mix one-time and subscription items in the same cart
  • Result: 40% subscription adoption rate

Technical Best Practices

1. Keep the critical path fast: Custom logic should not add more than 200ms to checkout load 2. Fail gracefully: If custom APIs are down, fall back to standard checkout 3. Test on real devices: Custom flows must work on low-end Android phones 4. A/B test everything: Use GoKwik's built-in experimentation for flow variants 5. Monitor conversion funnels: Track drop-off at each custom step
