## Which Platform Fits Your Business?

**WooCommerce** is the right choice when you need deep customization, own your infrastructure, or have complex requirements that Shopify's app ecosystem cannot cover. Custom payment gateways, multi-step booking flows, departure management, and tight integration with WordPress content.

**Shopify** is the right choice when you want a managed platform with managed hosting, built-in payment processing, and a faster path to launch. Multi-store architectures, B2B wholesale on Shopify Plus, and DTC brands with straightforward product catalogs.

We will tell you which platform fits before you spend money on the wrong one.

## Custom Payment Integrations

Payment processing is where most e-commerce projects get complicated. We have built custom payment gateway integrations that go beyond installing a Stripe plugin:

- **Regional bank integrations:** Custom WooCommerce payment gateways for Himalayan Bank and NABIL Bank, handling local currency processing, bank-specific authentication flows, and transaction verification
- **Donation processing:** Payment integrations with nonprofit CRMs for recurring donations, campaign tracking, and donor management
- **Multi-gateway routing:** Configuring stores to route payments through different processors based on currency, location, or transaction type

## Travel Booking and Departure Management

Our [travel and booking sites](/industries/travel) run on our WooCommerce infrastructure. They include:

- **Departure management:** Backend tools for managing trip dates, availability, capacity, and seasonal pricing across dozens of itineraries
- **Trip filter systems:** Complex search interfaces where travelers filter by destination, date, duration, difficulty, and price
- **Booking workflows:** Multi-step checkout with deposit collection, balance payments, traveler information forms, and booking confirmations
- **Inventory management:** Real-time availability tracking across multiple departure dates and trip variations

## B2B and Wholesale Commerce

B2B e-commerce has different requirements than DTC. We build wholesale portals with:

- Tiered pricing based on customer group, volume, or contract terms
- Custom product catalogs visible only to approved buyers
- Net payment terms and invoice-based checkout
- Approval workflows for new accounts and large orders

We have built B2B commerce on both WooCommerce (custom plugin development) and Shopify Plus (native B2B features).
