Task

  • Integration with multiple payment gateways: enabling payment acceptance through various channels: YooMoney, Sberbank and any third-party processing centers.
  • Fiscalization and reporting: transmitting data to the fiscal data operator and generating receipts in compliance with legal requirements.
  • Unified control point for orders and payments: automating invoicing, balance holds and updates, and order payment management.
  • Centralized reporting and reconciliation: ensuring transparency of financial flows, with automated reconciliations and reporting on payments and balances.
  • Interfaces for accounting and analytics: implemented reporting and reconciliation modules with customizable filters and data export capabilities.

What was done

  • Development of a modular billing architecture: the platform was built as a set of interconnected components - order processing, invoice creation, payment data transfer, funds blocking, reconciliation and reporting.
  • Integration with external payment systems and fiscal operators: enabled support for connecting any providers - YooMoney, Sberbank, internal payment gateways. A gateway for transmitting receipts to the fiscal data operator (FDO) was also implemented.
  • Automation of the invoice lifecycle: the system allows for invoice generation, balance tracking, funds blocking until payment confirmation, and automatic initiation of invoicing and closing processes.
  • Built-in notification system: notifications are sent to relevant users and systems for any actions - payments, invoice issuance, fund blocking, or errors.
  • Interfaces for accounting and analytics: reporting and reconciliation modules implemented with customizable filters and data export functionality.

How it works

  • For customers: Customers can place orders with instant invoice generation, receive notifications, and pay using their preferred method. After payment, a receipt is automatically generated and sent to the tax authority via the fiscal data operator (FDO).
  • For accounting and finance teams: With reconciliation tools, notifications, and analytics, financial flows are tracked in real time. It’s now much easier to control balances, payments and budgeting.
  • For developers and platform operators: The system enables fast integration of new payment providers and allows billing logic to be customized for different product categories, customer types and use cases.
