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
- 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
