Common questions about our e-commerce and retail software solutions
Development timelines vary based on complexity and features. A basic e-commerce MVP typically takes 3-5 months. Custom marketplace platforms can take 6-10 months. We provide detailed timelines after requirements analysis.
Development costs vary based on features, integrations, and complexity. Factors include the number of payment gateways, third-party integrations (ERP, shipping, marketing tools), product catalog size, custom features, and mobile app requirements. Shopify customization projects are typically more cost-effective than custom platforms. Multi-vendor marketplaces require more investment due to vendor management complexity. We provide detailed cost estimates after understanding your specific requirements.
The choice depends on your requirements. Use Shopify/WooCommerce for standard e-commerce needs and faster time-to-market. Build custom if you have unique workflows, complex integrations, or need complete control. We help evaluate the best approach based on your business model and growth plans.
