Custom Development

Custom Platforms For Problems
Shopify And WordPress Can't Solve

Some businesses have requirements that no template or plugin can handle. Multi-warehouse inventory. B2B partner portals with custom pricing tiers. E-commerce with 5,000+ SKUs, compatibility logic, and real-time stock sync. For these, we build from the ground up on Next.js.

When Custom Makes Sense

Not every problem needs a template

Before recommending custom development, we always ask: can this be solved with Shopify or WordPress? If yes, we tell you. Custom builds are more expensive and take longer — we only recommend them when the business logic genuinely requires it.

High-SKU Catalogues

More than 1,000 products with complex variants, compatibility logic, and attribute relationships.

B2B Partner Portals

Different customers see different prices. Tiered pricing, net payment terms, and custom Catalogs.

Multi-Vendor Marketplaces

Multiple sellers, each managing their own products, orders, and payouts from one platform.

Real-Time Inventory Sync

Live stock updates across multiple warehouses or branches. No overselling, ever.

Custom Business Logic

Admin backends with custom workflows — invoicing, partner management, team management.

ERP & API Integrations

Deep integrations with ERPs, accounting software, logistics APIs, and third-party tools.

The Decision Framework

Custom vs. Shopify — How We Decide

We don't push custom development unless it's genuinely needed. Here's our decision framework:

Choose Shopify when:

  • Standard product catalogue (under 1,000 products)
  • Basic variant logic (size/color)
  • Single customer type (retail OR wholesale)
  • Standard payment and shipping flows
  • No deep ERP integration needed

Choose Custom when:

  • Complex compatibility logic (PC builder, etc.)
  • Multi-warehouse inventory management
  • B2B + B2C from one system
  • Deep ERP/accounting integration
  • Performance requirements beyond hosted platforms
