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.
