GetPaidHQ: Smart Recurring Payment Processing Built for Modern Businesses

Project Overview

GetPaidHQ represents the next evolution in recurring payment processing, designed specifically for businesses that need more than basic subscription billing. Built on Domain-Driven Design principles and a clean architecture approach, this platform addresses the growing demand for flexible, usage-based pricing models that traditional payment processors struggle to support.

The platform distinguishes itself by offering three distinct billing approaches: traditional fixed subscriptions, pure usage-based billing, and hybrid models that combine both. This flexibility allows businesses to align their revenue models with actual customer usage patterns, creating fairer pricing for customers while unlocking new revenue streams for providers.

Core Capabilities

At its heart, GetPaidHQ provides comprehensive subscription management with support for complex billing scenarios. The real-time usage recording system captures billable events as they occur, automatically aggregating them by billing period to ensure accurate invoicing. This capability is particularly valuable for SaaS platforms, marketplaces, and telecommunications companies that need to bill based on actual consumption.

The platform's invoice generation goes beyond simple billing statements. Each invoice provides complete transparency with detailed usage breakdowns, showing customers exactly what they're paying for. This transparency reduces billing disputes and builds trust between businesses and their customers.

Advanced Features

GetPaidHQ's usage-based billing system supports both percentage-based pricing for transaction fees and unit-based pricing for resource consumption. This flexibility accommodates virtually any business model, from marketplace transaction fees to API call charges and data storage costs.

The platform includes sophisticated plan change handling with automatic proration, ensuring customers are charged fairly when upgrading or downgrading their services. Revenue recovery features include dunning management and automated messaging to reduce churn and recover failed payments.

Technical Architecture

The system is built using Go with a layered architecture based on Domain-Driven Design principles. The platform integrates with multiple payment providers including Paystack and Checkout.com, supports various authentication methods (API Key, Cognito, Clerk), and uses PostgreSQL for data persistence with Redis for caching.

The architecture supports extensive customization through its workflow engine (Temporal), pub/sub messaging (NATS), and queue system (AWS SQS). This foundation ensures the platform can scale with growing businesses while maintaining reliability and performance.

Business Value

GetPaidHQ enables businesses to capture usage-based revenue streams that traditional subscription models miss. Companies can start with predictable subscription revenue and add usage-based components as they grow, creating pricing models that scale with customer success.

The platform's transparency features reduce billing disputes and support costs, while its flexible pricing options help businesses optimize their revenue models. Whether you're running a SaaS platform with API usage, a marketplace with transaction fees, or a telecommunications service with usage-based charges, GetPaidHQ adapts to your specific needs.

Deployment Options

The platform offers dual deployment strategies to meet different business requirements. Companies can use GetPaidHQ as a managed B2B SaaS solution, or deploy it as a white-label solution in their own infrastructure for complete control over their payment processing.

This flexibility makes GetPaidHQ suitable for everything from startups needing quick deployment to enterprises requiring on-premise solutions with full compliance control.
