FAQ
Common questions
How much does a website cost?
It depends on scope. A focused business site costs much less than an online store or custom app. After a short call, you'll get a flat-rate quote with no hourly surprises. Most projects are split into a deposit up front and the balance at launch.
How long does a project take?
Most business websites launch in 2–4 weeks. Online stores and custom apps typically take 4–10 weeks depending on features and integrations. You'll get a timeline with your quote.
Do I own my website?
Yes. Your domain, code, and content are yours. If you ever want to move to another developer or host, we'll hand everything over.
Can you redesign my existing site?
Absolutely. We can rebuild on a modern stack while keeping your domain, search rankings, and content intact, with proper redirects so nothing breaks.
Can my website connect to my POS or other software?
Usually, yes. We've integrated websites with point-of-sale systems, Stripe, Shopify, and custom databases so inventory, orders, and customer data stay in sync.
How do I pay?
Projects are typically 50% up front and 50% at launch. You'll get a quote to review and accept online, then invoices by email with a secure Stripe payment link. Pay by card or bank transfer (ACH), and see everything anytime in your client portal.
What happens if I cancel my care plan?
Nothing is held hostage. Your plan runs to the end of the paid month, then we transfer the code and hosting to your own accounts (or help you move to any host you like) and hand over every login.
Will I be able to update the site myself?
Yes. Every project comes with a recorded walkthrough and a written guide. If your site needs frequent content changes, we can build in an easy editor so you can update text, photos, and products without touching code.
