Frequently Asked Questions
How do I know which eCommerce platform is right for my business?
Choosing the right platform depends on your size, budget, product catalog, and long-term goals. For example, Shopify is ideal for fast launches, Magento (Adobe Commerce) offers deep customization for complex catalogs, Salesforce Commerce Cloud is enterprise-grade with AI-driven personalization, WooCommerce works well for content customization, and OpenCart provides open-source flexibility at lower cost. We start with a consultation to match your needs with the right platform.
Can you migrate my current store without losing customer data or orders?
Yes. We follow industry best practices for data migration:
– Data assessment & mapping (align old and new platform structures)
– Data formatting & transformation (cleaning and converting)
– Validation & testing (ensuring no missing products, customers, or orders)
This reduces downtime and ensures a smooth transition.
Do you provide custom integrations with ERP, CRM, or loyalty systems?
Absolutely. We have integrated eCommerce platforms with SAP, Salesforce, HubSpot, custom POS, and loyalty programs.
Can you support multi-store, multi-language, and global selling?
Yes. We’ve built systems for Japan, Europe, and North America, including multi-currency checkout and localized content. Shopify, Magento, and Salesforce Commerce Cloud natively support these features, while WooCommerce and OpenCart achieve them via plugins.
Can I track and analyze the performance of my store across platforms?
Yes. Analytics options vary:
– Shopify: Built-in reports + Google Analytics integration.
– Magento: Advanced Business Intelligence dashboards.
– Salesforce Commerce Cloud: Einstein AI analytics for personalization.
– WooCommerce & OpenCart: Integrate with GA4 or third-party BI tools.
We set up performance tracking so you can monitor sales, customer behavior, and lifetime value.
How much does it cost to build or migrate an eCommerce store?
Cost depends on:
– The chosen platform (Shopify tends to have lower upfront costs; Magento and Salesforce are higher but more customizable)
– Store complexity (number of products, integrations, custom features)
– Ongoing support needs.
We provide a tailored proposal after an initial consultation.
How long will it take to launch or migrate my online store?
Time depends on platform, complexity, data volume, and integrations. Rough estimates:
– A simple store on Shopify or WooCommerce with standard theme and no heavy customizations: a few weeks (2-6 weeks).
– More complex projects (large catalog, custom UX, multiple integrations, internationalization) on Magento, Salesforce Commerce Cloud, or custom setups could take up to months.
Migration includes phases: project planning, data assessment & mapping, data transformation, integration testing, design/theme adjustments, QA, and deployment. Good vendors should factor in buffer for unexpected issues (data cleanup, third-party app compatibility).
How flexible are your development services with in-house teams?
We operate in Agile methodology and can embed dedicated engineers who collaborate directly with your in-house team. Our Project Management Office (PMO) ensures communication, timelines, and quality standards are consistent.
How can I ensure the confidentiality and privacy of my store’s data with maintenance services?
Here are some measures you can take to safeguard your data during maintenance:
– Non-disclosure Agreements (NDAs)
– Trusted and Verified Service Providers
– Limited Data Access
– Secure Communication Channels
– Data Backup and Disaster Recovery
Can you integrate AI-driven personalization into my eCommerce store?
Yes. We implement AI recommendation engines, chatbots, and personalized marketing automation. Salesforce Commerce Cloud has built-in AI (Einstein), while Shopify and Magento can integrate with AI tools for tailored experiences.
