Control catalogs, pricing, orders, customers, visits and sales performance through the panel.
For suppliers & distributors
Share products, define collaboration terms, request supply and follow quotations.
The order journey
When an order requires network supply, an inter-company request joins this workflow.

The challenge
Automotive parts distribution goes beyond placing orders. Many distributors restrict price visibility and offer different prices and terms to different customers. Products themselves can also be visible only to selected customer grades, cities or regions. Customer grading and geographic scope provide a basis for these differences, while visibility is a separate decision from calculating the price. Each company has its own catalog, pricing, customers and collaboration terms, while a customer order may depend on another company's supply, sales approval, payment and dispatch. The challenge was to connect these journeys while preserving company identity, settings and sales policies.
B2B CATALOG ACCESS & SALES TERMS
A catalog and sales terms tailored to each customer.
Distributors decide which products each customer can see, whether prices are visible and which prices and terms apply. Customer grade, city and region inform these rules, managed through each organization's administration panel.
- 1
Price visibility
Browsing the catalog does not imply public access to prices. Whether prices are shown follows the company's rules.
- 2
Product visibility by grade
Customer grades govern more than the purchase price. A product can appear for some grades and be entirely absent from the catalog for others.
- 3
City & regional scope
Product visibility can be limited by the customer's city or region. Customers in one area may see a product while customers in another do not.
- 4
Grade-based pricing
Cash or check-based prices and sales terms apply according to customer grade. The same product can have different prices for customers in different grades.
Example: a part is visible to an eligible grade in a served region, while a customer in another grade or region may not see it at all. Even among customers who can see it, price visibility and cash or check-based prices can differ. Each distributor defines its own access and sales policies.
COMPANY ACCOUNTING, CONNECTED TO THE CUSTOMER APP
From accounting software to current information in customers' hands.
A dedicated connector application is installed on the company's computer to connect accounting software such as Sepidar, Holoo, Argham System and other systems used by companies. It transfers accounting information to the platform, keeping prices, stock and customer statements updated in real time.
- 1
Company accounting
Product prices, stock and customer financial information are recorded and updated in the company's accounting software.
- 2
Locally installed connector
Dedicated software adapted to the company's accounting system retrieves information and transfers it to the platform.
- 3
Real-time updates
Price, stock and customer statement changes update the organization's online system.
- 4
Customer application
Customers see current prices, stock and their own statements in the app, according to their access and pricing grade.
Information flow: company accounting → dedicated connector → the organization's platform → customer app. The information exchanged depends on each accounting connector's capabilities.
Project journey & live example
From Argan Pakhsh to a multi-tenant platform.
Launching Argan Pakhsh
In 1396 of the Solar Hijri calendar (2017–2018), we launched the first version as Argan Pakhsh for an automotive parts distributor. The application connected the company with many auto parts stores across Iran, providing a B2B purchasing and order-entry journey.
View Argan Pakhsh on Cafe BazaarRebuilt around operational experience
Experience with the original product and its operational challenges shaped the rewrite. The new generation was developed with higher performance and quality and redesigned to address the issues encountered in use. Its multi-tenant architecture lets distribution companies and suppliers use a shared core with their own identity, settings and business policies.
ONE OF TODAY'S LIVE EXAMPLES
The purchasing view for an auto parts store
This example shows the auto parts store's purchasing journey: browsing products, selecting items and buying. It may look like a straightforward storefront, while the entire system workflow is controlled through the administration panel, from products and pricing to orders, supply, payments, dispatch and reporting.
The public view serves buyers; management capabilities are handled through the organization's panel and permissions.SYSTEM MAP

Orders and invoices, payments and installments, check submission and review, wallet history, sales shares and accounting connectors provide the existing foundation.
Scope defined in the document
The items below are requirements for the accounting module. Completing them requires separate implementation and verification; the document does not imply that every capability is ready.

ENGINEERING & DELIVERY
A coordinated architecture behind the flow.
My responsibility
System Designer, Lead Full Stack Developer & Project Manager
Worked across requirements analysis, architecture, backend and database development, administration panels and storefront interfaces. Pricing and order logic, inter-company workflows, accounting connectors and background jobs were central areas of my work. As lead developer and project manager, I focused on coordinating these components, translating business needs into practical workflows and building shared tools for development and maintenance.
Architecture & engineering decisions
Organization context in each request
Domain-based tenant resolution and organization context for settings, data and access enable dedicated sites and panels on a shared core.
Separate financial & network policies
Supplier purchasing rules are kept separate from customer sales terms. Changing a network purchase from cash to credit should not inadvertently change a customer's invoice price or payment method.
Connections to existing systems
Connectors and APIs exchange prices, stock and quotations between stores and accounting software, with tests, logs and processing queues supporting error investigation.
Background processing
Synchronization, analysis, image imports and backups run through jobs and queues so execution remains observable.
PRODUCT VALUE
Individual features become a manageable workflow.
The value lies in how the parts connect: pricing informs purchases, orders feed supply, and payments and sales performance remain traceable through reporting and settlement.
