FAQ
Common questions
Everything you need to know before starting a project with us.
Shopify or BigCommerce — which should I choose?
It depends on your catalog complexity, B2B needs, budget, and growth plans. Shopify excels at ease of use, app ecosystem, and DTC brands. BigCommerce offers more built-in features, no transaction fees, and stronger B2B tooling. We help you evaluate both during discovery and recommend the best fit — no platform bias.
How long does a typical project take?
A standard Shopify or BigCommerce store build takes 4–8 weeks. Migrations with large catalogs or complex integrations may take 8–12 weeks. We provide a detailed timeline in your proposal after discovery.
Can you migrate my existing store without losing SEO?
Yes. We map every URL, set up 301 redirects, migrate meta titles and descriptions, and submit updated sitemaps. Most clients see no meaningful SEO dip — many see improvement from faster page loads and better UX.
Do you offer ongoing support after launch?
Absolutely. We offer monthly retainer plans for bug fixes, feature additions, platform updates, and CRO experiments. You can also engage us ad-hoc for one-off projects.
What does a project typically cost?
Store builds start around $8,000 for a focused launch. Migrations and custom development range from $15,000–$50,000+ depending on scope. We provide fixed-price proposals after discovery so there are no surprises.
