The Problem
Standard e-commerce platforms handle the common case. Your business has the edge cases:
- Complex discounts: Promotional rules that don’t fit the platform’s discount system
- Custom shipping: Weight-based, freight, or pallet shipping beyond simple zone pricing
- B2B payment terms: Staged payments, net terms, or customer-specific pricing tiers
- Product complexity: Configurable products with thousands of variants
- Tax edge cases: Multi-jurisdiction rules or partial payment tax calculations
When you force your business to adapt to software limitations, you create friction for both staff and customers.
How I Solve It
I extend e-commerce platforms to match how your business actually operates:
Custom Discount Logic
- Mass discount application with correct stacking rules
- Product-specific promotions and tiered pricing
- Cart-based conditional discounts
- Customer-specific pricing and discount tiers
Custom Shipping Calculations
- Weight-based calculations with freight handling
- Pallet auto-assembly algorithms for optimal shipping
- Real-time carrier API integration (FedEx, UPS)
- Hazardous materials and oversized item handling
B2B Payment Features
- Staged payment systems (down payment, pre-shipping, net terms)
- Customer-specific payment terms stored in their account
- Partial payment tracking and invoice generation at each stage
- Integration with Avatax for partial payment tax calculations
Product Configuration
- 200,000+ SKU catalog architecture
- Variant structures for complex specifications
- Attribute inheritance for efficient catalog management
- Pricing matrices for B2B complexity
