Frequently Asked Questions

Should I build a custom store or use a platform like Shopify?

Ready-made platforms are great for simple, standard stores. We recommend a custom build when you need multi-vendor logic, complex pricing, or integrations that off-the-shelf platforms cannot support.

Can you migrate our existing store to a new platform?

Yes, we handle product, customer, and order data migration with a plan to avoid downtime during the switch.

How do you handle multi-vendor commission and payouts?

We build configurable commission rules and automated or manual payout workflows that match your marketplace's business model.

Which payment gateways can you integrate?

We integrate major international gateways like Stripe and PayPal, plus regional providers, along with cash-on-delivery workflows where needed.

Can the platform handle high-traffic sales events?

Yes, we design for peak load with caching, CDN delivery, and load testing before major campaigns or sales.

Do you provide ongoing support after launch?

Yes, including monitoring, seasonal readiness checks, and continuous feature development as your catalog and traffic grow.
