Frequently Asked Questions

What is a custom e-commerce solution?

A custom e-commerce solution is a tailor-built online selling platform designed specifically for your business model. Unlike off-the-shelf platforms like Shopify or WooCommerce, custom solutions offer complete control over features, user experience, integrations, and scalability — ideal for businesses with unique requirements such as custom pricing models, complex product configurations, or multi-vendor marketplace functionality.

How much does a custom e-commerce platform cost?

Custom e-commerce platform costs vary widely based on complexity. A basic custom store starts around $20,000-$40,000, while a full-featured marketplace with multi-vendor support, advanced inventory, and custom checkout can range from $50,000-$200,000+. We provide transparent pricing after a thorough requirements analysis and can phase delivery to manage budgets effectively.

How long does it take to build a custom e-commerce platform?

A custom e-commerce platform typically takes 3-8 months depending on complexity. An MVP with core shopping features can launch in 3-4 months, while a comprehensive platform with marketplace functionality, advanced analytics, and multiple integrations may take 6-8 months or more. We use agile sprints so you see working features every two weeks.

Can you migrate my existing store to a custom platform?

Yes, we handle complete e-commerce migrations including product catalogs, customer data, order history, SEO rankings, and URL redirects. We ensure zero data loss and minimal downtime during the transition. Our migration process includes thorough testing in a staging environment before going live, with rollback procedures in place for safety.

What payment gateways do you integrate?

We integrate all major payment gateways including Stripe, PayPal, Square, Razorpay, Authorize.net, and Braintree. We also support cryptocurrency payments, buy-now-pay-later services (Klarna, Afterpay), and custom payment solutions for B2B transactions with invoicing, net terms, and purchase order workflows.

Do you build B2B e-commerce platforms?

Yes, we specialize in B2B e-commerce platforms with features like custom pricing tiers, bulk ordering, quote management, purchase order workflows, account-based purchasing, and ERP integrations. Our B2B solutions streamline complex business-to-business sales processes with approval workflows and volume discount automation.

How do you handle e-commerce security and PCI compliance?

We implement end-to-end security including PCI-DSS compliance for payment processing, SSL/TLS encryption for all data transmission, tokenized payment storage, fraud detection algorithms, DDoS protection, and regular security audits. Customer data is encrypted at rest and in transit, with role-based access controls for administrative functions.

Can you build a multi-vendor marketplace like Amazon or Etsy?

Absolutely. We have extensive experience building multi-vendor marketplace platforms with vendor onboarding, commission management, automated payouts, vendor dashboards, product moderation, dispute resolution, and split payment processing. We design marketplace architectures that scale from a handful of sellers to thousands.
