CrateLoop subscription box platform

We run a curated subscription box business and need a full-featured web application covering the entire customer lifecycle. The core is a subscription engine with multiple tiers (Starter, Classic, Premium), where each plan is billed on a regular schedule and auto-renews. Subscribers should be able to skip the next box, pause billing for one to three cycles, or swap items in the upcoming set before a cutoff date—all through a self-service dashboard. New visitors take a short preference quiz (categories, sizes, dietary or style tags, allergens), and answers feed a personalization layer that matches the best box option. We need gift subscriptions with activation codes, scheduled first shipment dates and printed postcards, plus prepaid options for three, six and twelve months. When a customer clicks "cancel," the app triggers a win-back scenario: targeted discount, tier downgrade offer, or pause instead of hard churn. On the operations side we need a fulfillment queue that batches monthly boxes, generates picking sheets, hands off orders to the carrier and gives customers delivery tracking with email updates and a status feed. Result: responsive customer dashboard, catalog and curation admin, recurring billing via Stripe, quiz builder, gift module, churn automation, fulfillment and tracking, plus reports on active subscribers, MRR, churn rate and skip frequency. We need clean documentation and a staging environment for acceptance testing.
