Flask chatbot VS Code environment pack Documentation framework Static site Project InventoryDo you want to manage quotes, invoices, payments and business expenses in one system without relying on multiple SaaS platforms or paying recurring subscriptions?
This self-hosted invoicing system brings the entire billing workflow into your own environment, from quotes with electronic signatures to invoice generation, payment tracking, paid invoice documents, expenses and structured exports.
Available as a complete system or as independent modules, it is deployed directly on your server and remains under your control.
Quotes, invoices, payments and related business records use the same structured information throughout the system, reducing repeated data entry and keeping documents consistent.
The system includes:
Documents and exports remain organized within your own environment, making business records easier to access, verify and archive.
The system is designed for businesses operating in the United States, while remaining adaptable to the specific requirements of each business.
The standard system supports manual U.S. sales tax rates, allowing the business to apply the tax treatment and rates appropriate to its own operations.
Because U.S. sales tax rules can depend on the destination state and local jurisdiction, tax nexus and the specific taxability of the products or services sold, the standard system does not include a universal automated U.S. tax engine.
When automated tax determination is required, business-specific tax rules or a third-party tax engine can be integrated as a separate custom service. This allows the system to be adapted to the actual states, products, services and tax obligations of the business without imposing unnecessary complexity on every deployment.
Specific business requirements, additional integrations or custom workflows can also be handled as separate adaptations when needed.
This system is designed for freelancers, independent professionals and small businesses that want to manage their invoicing without depending on an external platform, paying a recurring subscription or handing control of their business documents to a third-party SaaS provider.
The system can be deployed as a complete solution or as standalone modules, depending on your business requirements.

Every deployment includes installation on your hosting environment, standard system configuration, validation testing, documentation and handover. Business-specific tax automation, tax-engine integrations and custom fiscal rules are quoted separately when required.
Once installed and configured, the system is designed to operate autonomously, without a maintenance subscription or mandatory recurring service.
Any future modification, additional feature, custom integration or specific technical evolution can be provided separately when needed.

This step reduces installation time and allows the system to be delivered preconfigured for your business.
