Overview

Physical products and digital subscriptions in one shop

Dopamine Drops BD is an e-commerce website I built for a client in 2026. It received more than 500 orders within about four months.

It sells physical products and digital subscriptions. I am a reseller, so customers can buy or renew subscriptions such as Spotify Premium directly on the site. Customers pay with bKash or cash on delivery.

Product tour

A walk through Dopamine Drops BD

    The home page brings together product categories, from digital subscriptions to phone cases, chargers, cables and powerbanks, and popular subscriptions such as Spotify Premium, Canva Pro and Netflix Premium. Search, wishlist and cart sit in the header, beside a link to the Aura leader board.

  3. 03Physical products

    A physical product has a photo gallery, feature highlights, live stock, a sale price, colour options and a quantity picker, then Add to cart or Buy now. Orders are paid with bKash or cash on delivery.

    The subscriptions page tracks each customer's plan with its duration and expiry: 150+ active, with counts for those expiring soon and those expired or cancelled, plus totals per product such as Spotify Premium, Canva Pro, Netflix, Google One and Crunchyroll. The list filters by status or by what expires in the next 7, 15 or 30 days, to stay ahead of renewals.

  12. 12Subscription detail

    One customer's subscription at a glance

    Each subscription has its own page: the plan, start and expiry dates, days left and renewal history, beside the subscriber, the product, the order it came from with its bKash payment, and quick stats.

    Subscription #341, active: a monthly plan started on 9 October and expiring on 8 November with 30 days left, no renewals yet, and side cards for the subscriber (blurred), the Canva Pro product, order #725 paid by bKash, and quick stats.

  15. 15Coupon builder

    A coupon, built from the ground up

    A new coupon starts with a code (typed or generated), a name and the message customers see at checkout, then the discount: a percentage with an optional cap on the maximum discount.

    Create coupon: coupon code with a Generate button, coupon name, a customer-facing description, and discount configuration with type, percentage and a maximum discount cap.

  16. 16Coupon rules

    Complete control over who, when and how often

    Every coupon can be tuned to the campaign.

    • Validity: a start and expiry date and time, or none for an always-on code.
    • Usage limits: a total limit, a per-user limit, and whether it can stack with other coupons.
    • Applicability: which products, which customers, a minimum order value and a minimum quantity.
    • Subscriptions: the discount can cover the first billing only, every billing for the lifetime of the subscription, or the first N billings.
    Coupon rules: start and expiry date and time, an active toggle, total and per-user usage limits, coupon stacking, products it applies to, customer eligibility, minimum order value and quantity, and which subscription billing cycles get the discount.

  17. 17Reports and settings

    Reports and store settings

    The admin sidebar also holds the reports and the settings that run the shop.

    • Reports: an overview, top customers, revenue, subscriptions and any custom date range.
    • Store settings: the top and hero banners, social links, bulk SMS and SMS templates, delivery, meta and storage.
    The admin sidebar: Reports (Overview, Top customers, Revenue, Subscriptions, Custom range) and Store settings (Top banner, Hero banner, Social links, Bulk SMS, SMS templates, Delivery, Meta, Storage).

  18. 18Behind the scenes

    Automatic SMS and Telegram alerts

    A scheduled cron job and a Telegram bot keep customers and admins informed without anyone checking the dashboard.

    • When someone buys, the customer gets an SMS on their phone confirming the order.
    • When a subscription is about to expire, the customer gets an SMS reminder to renew.
    • Every one of those messages is copied to the admins' Telegram group by the bot, so the team hears about new orders and expiring subscriptions as they happen.

What it does

What the shop does

  • Products and subscriptions in one store

    One storefront sells physical products, from chargers to phone cases, and digital subscriptions, with categories, search, filters, a wishlist and a cart.

  • Subscription plans

    Subscriptions such as Spotify Premium are bought or renewed on the site, with plans of 1, 3 or 6 months or a year, each with its price per month.

  • Product variations

    A product can have colour variations, each with its own price, compare-at price, stock and images.

  • Admin dashboard

    Orders, products, customers and active subscriptions at a glance, with order management by status, user management, product management for physical and digital products and an editor for details, pricing and media.

  • Subscription tracking

    Every customer subscription is tracked with its plan, expiry and days left, with counts for active, expiring soon and expired, and filters for what expires in the next 7, 15 or 30 days.

  • Coupon engine

    Percentage, fixed amount and free shipping coupons with bulk generation, validity windows, total and per-user limits, stacking rules, product and customer targeting, minimum order rules, and subscription discounts for the first billing, the first N billings or every billing.

  • Order and expiry alerts

    A cron job texts customers when they buy and when a subscription is about to expire, and a Telegram bot copies each alert to the admins' Telegram group.

  • Reports and bulk SMS

    Reports on revenue, top customers, subscriptions and custom date ranges, plus bulk SMS with reusable templates.

  • bKash, cash on delivery and delivery settings

    Customers pay with bKash or cash on delivery, and delivery is configured in the store settings.

My role

What I did

  1. Built it for a client

    Built Dopamine Drops BD for a client in 2026: the storefront, the admin and the automation behind them.

  2. Built the storefront

    Built the shop customers use: the home page, the catalogue with filters and sorting, product pages for physical goods with colour options and live stock, and subscription plans that customers buy or renew.

  3. Built the admin side

    Built the admin dashboard, order and user management, product management with variations and inventory, the three-tab product editor, subscription tracking with expiry, the coupon engine, the reports, and store settings such as bulk SMS and delivery.

  4. Automated the notifications

    Set up a cron job that sends customers an SMS when they buy and before a subscription expires, and a Telegram bot that copies every alert to the admins' group.
