B2B fuel marketplace with multi-round price negotiation.

GT Platform is a B2B marketplace for fuel, oil, diesel, gas, and bioethanol trading in the Ukrainian market. Structurally similar to Airbnb — suppliers list offerings at physical bases (fuel storage locations), and business customers can browse prices, densities, and available amounts, then create orders, negotiate terms, sign contracts digitally, process payments, and arrange pickup logistics. The client, ********, is a Ukrainian fuel business owner with three existing bases who wants to digitize his operations and expand into a marketplace where partners and competitors can also list their offerings and services (fuel sales, tank storage rental, blending, tax services).

Challenge.

Client challenge: client's company had an existing platform built on 1C (a Ukrainian/Russian accounting and ERP system). The 1C-based customer interface was ugly, extremely slow, and customers refused to use it. He needed a modern frontend that would drive adoption while preserving his existing 1C backend for accounting and order management. During discovery, the scope changed approximately 50% as real requirements surfaced — a typical outcome when moving from a vague vision to actual product definition.

Technical challenges: Building a middleware layer to integrate with the legacy 1C platform. Complex multi-round negotiation workflow for orders (customers propose prices, suppliers counter, both parties iterate until agreement). Integration with Ukrainian digital signature providers for legally binding contract execution. Real-time currency rates from local bank APIs. Commodity price feeds. News scraping from Ukrainian oil and fuel industry sources via Puppeteer. Map-based UX for base locations using Mapbox.

Cultural challenge: The client's existing team operates with bureaucratic processes, while Reliqio operates as a fast, agile startup environment. This mismatch created friction and some wasted time on unnecessary formalities.

Solution.

Built a Node.js/NestJS middleware layer between the legacy 1C backend and a modern React frontend. The architecture preserves the client's entire existing accounting and order infrastructure while delivering a fast, professional user interface. Designed and developed within 2.5-3 months. Implemented the full order lifecycle: browse bases and offerings → compare options → create order → negotiate price and terms → digitally sign contract → process payment → arrange pickup logistics.

Impact.

UX: Transformational improvement — from an unusable 1C interface that customers rejected to a modern, Figma-designed React application with Mapbox maps, offering comparison tools, and streamlined negotiation workflows.

Platform Adoption: The old system had zero voluntary customer usage. The new platform is designed to drive adoption and is about to ship to production.

Business Expansion: Enables client to scale from three owned bases to a marketplace model where external suppliers can list their own offerings and services.

Client Relationship: Client's satisfaction is validated by the engagement expanding far beyond the original scope. He has already commissioned a second product (Mira, under NDA) and has two additional AI-heavy products planned — making this a four-product relationship from a single client.

Features.

Dashboard: Hot offerings, currency exchange rates (EUR/USD/UAH via local bank API), oil/diesel/gas market prices, market news (scraped from industry sources), analytics across the organization (amount spent, amount delivered), critical documents, documents pending signature, orders pending payment.

Bases: Base directory with photos, search and filter by type. Offering comparison tool to evaluate multiple bases side by side. Mapbox-powered interactive map with base pins. Base detail pages with imagery, facility map schemes, location in map with Google Maps routing, available services (storage, blending, filtering, mixing), product listings, descriptions.

Orders: Product order creation form (select basis, product, amount, desired price, pickup date, notes). Multi-round negotiation workflow with status tracking and counter-offers between customer and supplier. Digital signature integration with Ukrainian e-signature providers. Payment status tracking via 1C integration. Document management per order. Order detail view with product info (density, basis, supplier, amount, payment status).

Pickups: Pickup creation form (truck number, reservoir number, vehicle model, driver name, driver license, delivery organization searched by tax ID). Pickup list with statuses. Pickup detail pages with supplier-generated documents and approval status.

Suppliers: Supplier summary view with documents signed, amounts paid and delivered, spending charts, critical orders, supplier contact information.

Settings: Organization settings (name, email, phone, branding). Personal account settings. Logout, email and password reset. Role-based access planned for future.

Authentication: Firebase Authentication.
