Yellowcube API is a full-featured business operations platform developed for Yellow Cube Kft. It brings sales, partner management, subscriptions, finance, and internal administration into one secure and scalable system.
I developed the platform to support the complete business lifecycle—from managing partners, suppliers, products, and contacts to following deals through sales pipelines, quotes, orders, deliveries, and renewals. It also automates complex commercial processes such as subscription cycles, commission calculations, payment tracking, currency conversion, VAT handling, and financial reporting.
The platform includes role-specific dashboards for administrators, managers, suppliers, resellers, and internal users. These dashboards provide actionable business insights through sales statistics, pipeline visualizations, commission reports, partner performance data, calendars, and activity tracking.
I also implemented document and workflow functionality, including invoice, contract, and purchase-order uploads, branded PDF generation, QR-code support, release management, notifications, and data export capabilities. Real-time updates improve collaboration and keep users informed without requiring manual page refreshes.
Security
Security was a core part of the platform. The system supports role-based permissions, JWT authentication, two-factor authentication, WebAuthn/passkeys, reCAPTCHA, and protected API operations.
Overall, Yellowcube API is more than an administration panel: it is an integrated business platform that streamlines operational workflows, centralizes commercial data, and gives different user groups the tools and visibility they need to work efficiently.
