Custom Product Information Management (PIM) System

Client Challenge

The business relied on separate Excel files to manage product, supplier, stock, and pricing data. This made updates slow, manual, and error-prone, especially when supplier prices and stock changed frequently.

Overview & Key Features

A custom-built Python-based Product Information Management (PIM) platform designed to centralize and automate critical business operations. Deployed across multiple Windows workstations, the system serves as the core hub for product information, supplier integrations, inventory synchronization, pricing management, auditing, and e-commerce updates. Built around internal business workflows, the platform provides secure, near real-time data synchronization and extensive automation to improve efficiency and maintain data consistency across systems.

FAQs

Why use PostgreSQL instead of MongoDB for a PIM system?

PostgreSQL is best for structured, relational business data such as products, suppliers, pricing, stock, and audit history. MongoDB is better for flexible document-style data.

Why use an API between clients and the database?

An API keeps business logic, security, validation, and database access centralized. Desktop clients do not connect directly to the database, making the system safer and easier to maintain.

How can real-time updates be sent to Windows clients?

Server-Sent Events, or SSE, can push updates from the server to connected desktop clients when products, pricing, stock, or sync statuses change.

When should webhooks be used?

Webhooks are used when an external system, such as WooCommerce, needs to notify the platform that something happened, such as an order, product update, or stock change.

When should APIs be used?

APIs are used when the platform needs to request, send, update, or retrieve data on demand, such as updating WooCommerce prices or fetching product information.

Solution

A custom Python-based PIM platform was built to centralize product, supplier, stock, pricing, and e-commerce data.

The system replaced disconnected Excel workflows with one shared platform, automated supplier imports, applied pricing rules, synchronized WooCommerce data, and provided audit history for better control and traceability.

Who It’s For

Ideal for retail, wholesale, distribution, and e-commerce businesses that manage large product catalogues, frequent supplier updates, and complex pricing or stock workflows. Best suited for companies that have outgrown Excel and need a custom system to centralize, automate, and control product data.
