Designing a Unified Payment Settlement Platform: Blueprint, Challenges, and Lessons

01. Make Everyone See

The product manager’s mission is to solve problems using a product as a tool, always returning to the enterprise’s scenario to deliver the optimal solution.

When the author joined a company as the product lead for the payment settlement middle‑platform, the senior director asked for a complete blueprint and an internal presentation. At that time the organization had no clear middle‑platform strategy, so the presentation needed to define the future vision.

First, the author collected product and business information from the team and stakeholders, learning about past, present challenges, pain points, and future expectations. After a week of discussion, the current state of the settlement business and the responsibilities of the middle‑platform were summarized (see diagram below).

The analysis revealed five major problems:

System construction is fragmented

Severe business coupling

Weak product configurability

Poor data accuracy

Low service abstraction

To address these, the author proposed five central hubs:

Unified Clearing Center

Unified Accounting Center

Unified Account Center

Unified Settlement Center

Unified Reconciliation Center

Beyond the core middle‑platform services, these hubs will provide comprehensive financial solutions such as wallet services, merchant settlement, B‑merchant settlement, insurance settlement, employee exit settlement, guarantee fund, and commission fund solutions, extending the middle‑platform’s reach into the business front‑end.

02. One Diagram Determines Destiny

The author created a single diagram that captures both the business layer and the account layer of the unified account center.

The diagram consists of two parts:

Business Layer

Describes the scenarios the unified account middle‑platform serves and the user groups involved, including wallet business, financial processing, balance payment at cash registers, corporate settlement platforms, and the account console.

Account Layer

Divided into three tiers:

Basic Capability Layer: Core account functions such as entity management, account management, balance management, transaction handling, and ledger management.

Service Layer: Exposes services like entity changes, account opening, and information queries to both internal and external systems.

Solution Layer: Packages the services into ready‑to‑use financial solutions (e.g., settlement schemes, corporate settlement, enterprise payment channels).

This service‑oriented approach makes capabilities visible, selectable, composable, and customizable for users.

03. Make Yourself Irreplaceable

Over the next three years, the department will continue to build on these five centers, standardizing, configuring, and abstracting services to a high degree of perfection.

When the author eventually leaves, the goal is to have completed all planned constructions, with the demand dropping to just two tickets per quarter while still achieving top performance.

The key insight is that understanding the past clarifies the present and illuminates the future; with a clear vision, a single diagram can drive decisive action.
