Equity Research Subscription Platform
A subscription platform for a regulated equity research firm — identity verification, digital client agreements, recurring payments and a full compliance back-office, built around the audit requirements that regulated advisory work carries.

Project Overview
Investment advisory is a regulated business, and most of the engineering difficulty sits in compliance rather than the product surface a subscriber sees. Before a client can receive a single recommendation, the firm must verify their identity against a central registry, capture a digitally signed agreement, and retain an auditable record of both.
We built the platform end to end: a public marketing and disclosure site, a subscriber area serving research recommendations, and an administrative back-office covering onboarding, billing, content and regulatory reporting.
The Challenge
Identity verification had to run against a central KYC registry, with request and response payloads encrypted and every call retained for audit.
Client agreements required legally valid e-signature, including asynchronous webhook callbacks when a signing completed out of band.
Regulatory obligations meant an append-only audit trail across administrative actions, not just a change log on the primary records.
Subscriptions needed plan changes, coupon-based discounting and usage tracking without losing the billing history behind each account.
Mandatory disclosure content — investor charter, complaint redressal, risk disclaimers — had to be maintained by the firm rather than hard-coded.
What We Built
KYC integration with a central registry, including AES-encrypted request handling and dedicated tables logging every vendor API exchange.
E-signature integration for client agreements, with webhook handling so signing events complete reliably outside the user session.
Subscription engine covering plans, lifecycle transitions, and a coupon system with per-code usage tracking.
Payment gateway integration for checkout and recurring billing, with the payment record kept separate from subscription state.
Multi-channel notifications — email, SMS, WhatsApp and push — with per-user preference controls.
An audit trail that backfills historical records on startup, so the log is complete rather than beginning at deployment.
A grievance and complaint redressal workflow, plus firm-editable disclosure pages.
Research recommendation feed with detail views, and an editorial section for long-form market content.
Delivered
The firm can onboard a client end to end — identity verified against the central KYC registry, agreement digitally signed, both retained as auditable records — before any recommendation is issued.
Signing completes reliably outside the user session through webhook handling, so an agreement finished hours later still lands correctly.
Every regulated third-party exchange has its own audit-log table, so vendor calls are independently reviewable rather than inferred from application logs.
The audit trail backfills historical records on startup, so the log is complete rather than beginning on deployment day.
Mandatory disclosures — investor charter, complaint redressal, risk disclaimers — are firm-editable, so a compliance update no longer needs a release.
Subscriptions handle plan changes and coupon-based discounting without losing billing history, with payment records kept separate from subscription state.
A 19-entity data model and 94 REST endpoints across 14 modules, with 19 dedicated administrative screens alongside separate public and subscriber areas.
