// How to build D2C Fashion Store with Try-Before-You-Buy Programme
Try-before-you-buy reduces D2C fashion return anxiety and lifts conversion 3–4×. The key technical challenge is Razorpay payment authorisation (hold on card at order, capture only for kept items after 7 days) plus a reverse logistics workflow. Next.js API Routes avoid a separate backend for this scale. Neon serverless Postgres scales to zero cost between order spikes.

## What to build in the MVP
—Product catalogue with size guide, photos (Cloudinary) and inventory
—Try Box selector: pick up to 5 items per box
—Razorpay card authorisation hold at order placement
—Automated 7-day trial window with SMS/email reminders
—Keep/return decision UI with partial capture and refund
—Reverse pickup booking via Shiprocket API

## Engineering risks to plan for
!Razorpay card authorisation (not capture) has a 7-day maximum hold; design the return window to fit within this constraint.
!Reverse logistics quality from Shiprocket varies by PIN code — build a fallback to manual pickup booking in the admin panel.
!Inventory management across try boxes in transit is complex; treat each Try Box as an order with item-level state from day one.
