B2B Electronic Sales & Instant Invoicing
Facilitating massive commercial transactions and reliably processing 10,000+ daily orders

Project Overview
Built a gigantic B2B E-Commerce store targeting retailers for wholesale orders, complete with an engineering infrastructure supporting high traffic pressure, alongside secure, invisible routing integration with the Zakat, Tax and Customs Authority (ZATCA Phase 2).
The Challenge
The client suffered from the difficulty of manually issuing compliant e-invoices for over 5000 daily orders, leading to frequent accounting blunders and inevitable compliance risks with tax auditors.
Architectural Solution
We built a Microservices platform featuring dedicated servers for payment processing (Payment Engine) and ZATCA-linked servers to cryptographically stamp every XML invoice instantly, seamlessly returning the required QR code.
Key Features
Phase 2 Instant ZATCA API Integration
Multi-warehouse & Geographical mapping support

Sales growth through automated, highly streamlined ordering
Flawless legal & tax compliance totally securing company operations
Methodology Used
