I need a production-ready Subscriber Management & Billing System built in Python/Django with a PostgreSQL backend. The goal is to give our Pay-TV operation full ownership of the source code while seamlessly driving CryptoGuard CAS for card activations, renewals and suspensions. Core domain The application must understand a multi-tier structure of dealers, sub-dealers and end users, each with their own wallet balance tracked through a simple ledger model. Cards and STBs move through that hierarchy, so the database has to record inventory ownership changes and keep a complete audit trail at every step. Business flow A dealer tops up a wallet, assigns or transfers a card, selects a product, and the system should instantly hit the CryptoGuard API to push the corresponding entitlement. When a cycle is about to expire, scheduled tasks must handle renewal or suspension automatically, again calling CryptoGuard and writing back the result to our ledger, the card record and the customer’s subscription history. User experience I am happy with the standard Django admin for internal staff, but a lightweight responsive front-end (Django templates or React, your choice) is required for dealers to see balances, move cards and trigger transactions. Every action has to land in an immutable audit log and feed simple dashboards so we can visualise active cards, expiries, cash flows and commissions at a glance. Deliverables & acceptance • Full Git repository containing Django project, PostgreSQL schema migrations, Celery/Redis (or preferred) task queue setup and all CryptoGuard integration modules • Environment files or Docker compose so the stack spins up locally • REST endpoints (DRF is fine) documented via Swagger/OpenAPI • Basic unit and integration tests that cover at least the billing cycle, wallet debit/credit, and a successful CryptoGuard entitlement call • A short deployment guide so we can drop the code onto our own servers without any licence dependencies If you have prior Pay-TV, CAS or fintech wallet experience, highlight it—otherwise solid Django architecture and clear, testable code will speak for itself.

Hi, this is Elias from Miami. I read your scope and it’s very clear: you need a production-ready Django + Postgres subscriber management and billing system that you fully own, with a clean dealer → sub-dealer → end user hierarchy, wallet ledger, inventory custody tracking (cards/STBs), and a tight CryptoGuard CAS integration for activation, renewal, and suspension. Plus scheduled jobs (Celery/Redis) to handle expiries automatically and write everything back into an immutable audit trail. I can build this as a proper domain-driven Django app (ledger-first), where every balance/inventory change is an append-only event, and the “current state” is derived and dashboarded. CryptoGuard calls get wrapped with idempotency + retries, and every entitlement request/response is stored for traceability (so you can audit exactly why a card is active or suspended). Q1: Do you already have the CryptoGuard API spec, and does it support idempotency keys (or should we implement our own request fingerprinting to prevent double-entitlements)? Q2: How are commissions calculated across dealer/sub-dealer (fixed per sale, %, tiered by product, or both), and do you need commission ledger entries separate from wallet ledger? Timeline-wise, a solid POC → production-ready MVP typically lands in 4–6 weeks depending on CryptoGuard complexity and commission rules. Regards,

Hello! We can design and build this Subscriber Management & Billing System as a production-ready Django application with full source-code ownership and a clean, auditable architecture. Our team has strong experience with Python/Django, PostgreSQL, ledger-based billing, and API integrations, which aligns well with your Pay-TV and CryptoGuard CAS needs. The system would be built around your multi-tier hierarchy, with a proper wallet ledger, immutable audit logs, and full traceability of cards and STBs. Core flows top-ups, assignments, transfers, renewals, and suspensions would run server-side via scheduled background jobs, ensuring reliable CryptoGuard API interaction and consistent subscription and entitlement state. For UX, we can use Django Admin for internal staff and provide a lightweight, responsive dealer interface showing balances, card actions, transactions, and key dashboards. Delivery includes a complete Git repository with migrations, background task setup, CryptoGuard integration, documented REST APIs, Docker or environment setup, essential tests and a concise deployment guide so your team can run everything independently.

I am Sumit Joshi from Sacesta Technologies. I can build this Django + PostgreSQL subscriber and billing system with dealer hierarchies, wallet ledger, inventory custody, and a reliable CryptoGuard CAS integration, keeping everything self-hosted and audit-safe. How I’d structure it Core models: dealer tree, users, wallets with double-entry style ledger, cards and STBs, subscriptions, products, commissions, and an immutable audit log. Inventory transfers will be event-based so every ownership change is traceable and reversible through history, not edits. CryptoGuard integration A dedicated service module with idempotency keys, request signing, retries, and full request response logging. Every entitlement call writes a transaction record tied to ledger entries and subscription state, so reconciliation is easy. Billing automation Celery + Redis for scheduled renewals and suspensions, with safe locking to prevent duplicate runs. Tasks will update subscription history, debit wallets, apply commissions, and trigger CryptoGuard, then persist results. Dealer portal A lightweight responsive UI for balances, card moves, activations, renewals, and transaction history. Django templates can be fastest and simplest, with DRF for APIs and admin plus portal sharing the same permission layer. Regards, Sumit Joshi
