Shopify Developer Needed: Single-Product Website with Subscriptions, Fulfillment Integration & Ad Tracking

We’re a San Francisco branding and creative agency, looking for an experienced e-commerce developer to build and launch a website for Nineli, a premium prenatal supplement brand. This is a focused, single-product website. We have an existing website design direction and need someone who can translate it into a beautiful, fast, fully functioning store. The site will receive traffic from Instagram, Facebook, TikTok, and potentially YouTube. It needs to look excellent on mobile and make purchasing easy. Design and website build Build a responsive website closely following the attached design, including: Product hero section with clear purchase buttons. Founder story with embedded video. Product benefits, ingredients, and formula information. Brand story and daily ritual sections. Customer testimonials, including video. Expert profiles. One-time purchase and subscription options. Expandable FAQs. Section for video content (like a library) Email signup, navigation, and footer. The attachment shows the main homepage. Please identify and include any supporting pages needed for a complete store, such as product details, contact, FAQ, shipping and returns, and policy pages. State the page count included in your quote. We will supply final approved copy, branding, product photography, and video assets. Please flag any additional design files or assets you need. E-commerce and subscriptions Set up the product, cart, secure checkout, and payment processing. Offer both one-time purchases and monthly subscriptions. Allow subscribers to manage their subscriptions, including skipping, pausing, canceling, and updating payment or shipping details. Configure shipping, tax settings, discount codes, and customer order notifications using information we provide. Include customer account access and subscription terms at checkout. The mockup currently shows an $89 one-time purchase and a $71 monthly subscription. Final pricing and subscription terms will be confirmed before setup. Fulfillment integration Connect the store to our fulfillment partner so that: New orders and recurring subscription orders are automatically sent for fulfillment. Inventory availability stays synchronized. Shipping status and tracking numbers return to the store. Customers receive shipping notifications. We will provide the fulfillment partner’s name and integration documentation. Please explain whether your quote assumes an existing connector or includes custom integration work. Clearly identify any costs that depend on reviewing the partner’s system. Advertising and analytics Set up and verify: Google Analytics 4 with e-commerce tracking. Meta tracking for Facebook and Instagram. TikTok tracking. Product view, add-to-cart, checkout, and purchase events, including purchase value. Appropriate consent settings and supported server-side tracking where available. Campaign attribution using UTM links. Please price Google Ads/YouTube conversion tracking as a separate option. Paid campaign management and ad creative production are outside this assignment. Testing, launch, and handover The finished website must be ready to accept real orders. Please include: Mobile, desktop, and major-browser testing. Image and video optimization for loading speed. Basic SEO setup and accessibility checks. Testing of one-time purchases, subscription signup and renewal, and the fulfillment workflow. Verification that advertising purchase events report correctly without duplication. Domain connection and launch. A short training session and handover documentation so our team can update content. 30 days of post-launch support for defects. The store, domain, analytics, and integration accounts must be owned by the client. Please include in your proposal Two or three relevant live e-commerce examples, preferably single-product or subscription brands. Your recommended platform, theme, subscription app, and fulfillment approach. A fixed project price, broken down into website build, subscriptions, fulfillment integration, tracking, and launch. All ongoing platform, theme, app, and maintenance costs, listed separately. Your estimated timeline and earliest start date. What you need from us to begin. Your assumptions, exclusions, revision allowance, and payment milestones. Whether you will personally complete the work or use a team. Shopify is preferred, but we’re open to a well-supported alternative if you explain the advantages. We’re looking for someone with a strong eye for design and proven experience taking an e-commerce website all the way through launch. Please review the attachment and respond specifically to this project.
