FAQs

Frequently Asked Questions

What is custom e-commerce development?

It's the process of building an online store from scratch, tailored specifically to your business requirements, rather than using a pre-built platform like Shopify or Magento. This gives you complete control over design, features, and functionality.

When should I choose custom development?

Choose custom development when you have complex business rules, need deep integration with legacy systems, require unique features not available on any platform, or want complete ownership and flexibility for long-term growth.

How much does custom e-commerce development cost?

Costs vary significantly based on complexity, features, and integrations. Custom solutions are an investment. Contact us with your requirements for a detailed project estimate and we'll work within your budget.

How long does it take to build a custom store?

A custom e-commerce solution typically takes 3-6 months for a minimum viable product (MVP), depending on complexity. Larger enterprise projects may take 6-12 months. We follow an agile process to deliver value incrementally.

Do you provide ongoing support for custom sites?

Yes, we offer comprehensive ongoing support including maintenance, security updates, backups, performance monitoring, and feature enhancements. You can reach us via Skype, Email, WhatsApp, Google Meet, Slack, or phone.

Can you integrate my custom store with my ERP/CRM?

Absolutely. We specialize in building robust integrations with various ERPs, CRMs, PIMs, and logistics systems using APIs and middleware to ensure seamless data synchronization.

Is a custom solution secure?

Yes, when built correctly. We follow industry best practices for secure coding, data encryption, and PCI compliance. We also conduct regular security audits and penetration testing.

Will I own the source code?

Yes, with custom development, you have complete ownership of the source code, database, and all intellectual property. There are no licensing fees or platform lock-in.

Do you provide prototypes before development?

Yes, we always create interactive prototypes or mockups for your approval before starting development. This ensures we're aligned on design and functionality from the start.

What if I need to add features later?

Custom solutions are designed to be flexible and scalable. Adding new features or integrations later is straightforward since you have full control over the codebase and architecture.
