Case Studies

Selected case studies.

A selection of systems and projects we've designed, delivered and integrated — from secure ERP integration to large-scale product platforms, broadcast media workflows, regulatory compliance and enterprise project delivery.

Enterprise Systems Integration

Field Sales App with Secure Oracle EBS Integration

Business Challenge: The client needed a mobile app for field sales reps to record orders directly against Oracle EBS — but Oracle EBS could not be exposed to the public internet under any circumstances, which ruled out a direct app-to-database connection.
What We Delivered: BigBox analyzed the requirement and built a custom mobile sales app backed by a middleware layer. Orders are written to a queue, and a custom syncing utility running on the internal network picks them up and writes them into Oracle EBS — the app and the public network never touch the database directly.
Technology / Integration Involved: Custom mobile app, middleware API layer, queue-based sync utility, Oracle E-Business Suite (EBS), internal-network-only connectivity.
Outcome: Field sales orders now reach Oracle EBS reliably through the queue-and-sync pattern, with the core database kept fully inside the internal network and never exposed publicly.

Multi-Site E-Commerce Platform

Multi-Site Product Catalog & OMS at Scale

Business Challenge: A catalog of 1 million+ products needed to be advertised across an unlimited number of websites, with each site able to set its own pricing, attributes and titles for the same underlying product — without sacrificing performance at that scale.
What We Delivered: BigBox analyzed the catalog and multi-site requirements and built a system that serves one master catalog to many storefronts, with per-site overrides for pricing, attributes and titles, plus complete custom dashboards for order management (OMS) and financial impact.
Technology / Integration Involved: Custom multi-site catalog engine, Elasticsearch for search, a caching layer for response speed at scale, custom OMS dashboard, financial-impact reporting dashboard.
Outcome: A single 1 million+ product catalog now powers multiple storefronts at once, each with independent pricing, attributes and titles, while staying fast at scale — with management able to see orders and financial impact across every site from one dashboard.

Broadcast Media Systems

Commercial Transmission Schedule Module for Radio & TV

Business Challenge: A reputable media client needed to manage the complete content lifecycle — from release order through to transmission — along with the invoicing and General Ledger impact that follows, across both their Radio and TV operations.
What We Delivered: BigBox built a complete Commercial Transmission Schedule (CTS) module covering the full workflow — Release Order, Transmission Certificate, Invoicing, and the resulting General Ledger impact — with dedicated modules for both Radio and TV.
Technology / Integration Involved: Custom Commercial Transmission Schedule (CTS) module, Radio module, TV module, invoicing, General Ledger (GL) integration.
Outcome: The client now runs release, transmission, invoicing and GL posting as one connected workflow across both Radio and TV, instead of separate manual steps.

Regulatory Compliance Integration

FBR Digital Invoicing Platform, Integrated Directly with the ERP

Business Challenge: Pakistan's FBR (Federal Board of Revenue) made digital invoicing a requirement. The client's ERP was from an international vendor, and when they asked that vendor to build the FBR/PRAL integration, the vendor came back with a very high quote — integrating directly with PRAL (Pakistan Revenue Automation Limited), which operates FBR's digital invoicing system, was itself a serious technical challenge.
What We Delivered: BigBox built a custom digital invoicing module that connects directly to the client's ERP through its reporting layer — fetching invoices, validating them against FBR's requirements, and pushing them to FBR/PRAL. The solution covers the full compliance lifecycle: the 72-hour cancellation window, QR code generation, FBR invoice reference numbers, and a custom dashboard, with an onboarding flow where a company can be registered in a few clicks and taken through FBR's required test scenarios before posting live invoices.
Technology / Integration Involved: Custom digital invoicing module, direct ERP report-based integration, FBR/PRAL integration, QR code generation, company onboarding & custom dashboard.
Outcome: The client avoided the international vendor's high quoted cost by having the FBR/PRAL integration built directly against their ERP, with the full compliance lifecycle — validation, cancellation window, QR code, reference numbers — handled end to end, and new companies can be onboarded and validated against FBR's test scenarios in a few clicks.

Project Delivery & Systems Integration

Oracle Fusion Integration Recovery & On-Time Go-Live

Business Challenge: A tracking company processing 20,000+ invoices a month was integrating Oracle Fusion with their internal financial system and an internally-built CRM. Delivery was running into roadblocks between the client's internal team and the external integration company, putting the agreed go-live date at risk.
What We Delivered: BigBox stepped in as project management liaison between the client's internal team and the integration company, clearing the roadblocks that were stalling delivery and keeping the Oracle Fusion, CRM and finance integration on track — while also contributing directly to the application integration work itself.
Technology / Integration Involved: Oracle Fusion, internal financial system, internally-developed CRM, coordination with a third-party integration company.
Outcome: The Oracle Fusion, CRM and finance integration went live on the originally agreed date — supporting a business processing 5,000+ invoices a month — after BigBox's liaison work cleared the roadblocks that had been putting delivery at risk.
