Overview

InvoiceShelf brings estimates, branded invoices, expense tracking, payment records, and business reports together in a web application. Its open-source AGPL-3.0 plan costs 0.00 USD per free, lasts forever, and has no seats or subscription. That is a compelling fit for small businesses, agencies, and consultancies that want predictable software costs and can handle self-hosting. It is a weaker choice for teams looking for a hosted service that requires no infrastructure work.

Key features

Invoices, payments, and customer access

Custom fields, tax rules, multi-currency support, and PDF templates give businesses useful flexibility when preparing invoices and estimates. Recurring invoice generation covers retainers, subscriptions, and repeat customers, while invoice tracking, payment reminders, and overdue-balance reports help users follow collections. The ability to record partial as well as full payments is useful when customers pay in stages; Stripe checkout adds online card payments. Customers can view invoices, estimates, and payments through a private portal without setting up a separate account.

Expenses, reporting, and operations

Expense tracking and reports covering sales, taxes, overdue balances, and profit give owners a broader view than invoice totals alone. UI backups can include the database, files, or both, which gives administrators options when planning routine backups. Remote file storage drivers include Dropbox, Amazon S3, and DigitalOcean Spaces, providing alternatives to local file storage.

Extensions and setup

A REST API using Sanctum tokens and a module system give developers ways to extend or connect the application. Webhooks are marked as coming soon, so teams that depend on event-driven integrations should not assume that capability today. InvoiceShelf 3 documentation describes MCP connections for Claude, ChatGPT, Claude Code, and Cursor, with read-only or read-and-write access; the MCP server is available in version 3.0.0-alpha.5 and stays off until a super admin enables it. The download requirements—PHP 8.3 or 8.4, a web server, and a supported database—make technical ownership part of the purchase decision, even though the software itself is free.

Pricing

The InvoiceShelf plan is 0.00 USD per free, free forever, open source under AGPL-3.0, and self-hosted. It allows unlimited invoices and customers with no seats or subscription. There is no free trial because the product is free, and the plan's uncapped invoicing is particularly attractive to a growing small business. The trade-off is that the plan does not remove hosting and setup responsibilities. Community support is through Discord, with GitHub Discussions linked for installation help.

Platforms

InvoiceShelf is available as a web application, with self-hosting and an API among its platform options. The listed requirements include PHP 8.3 or 8.4, Nginx or Apache, and MySQL 8+, MariaDB 10.4+, PostgreSQL 13+, or SQLite 3.35+. It suits organizations able to provide that environment; readers seeking an app across desktop and mobile operating systems may prefer a different option.

Who it's for

InvoiceShelf is a good match for individuals and small businesses that want control over billing data and can maintain a web application. Agencies and consultancies can benefit from recurring invoices, expense records, and reports without adding a subscription or per-seat charge. It is not the natural choice for teams that need a managed service, mobile-native apps, or webhooks as a current integration method.

Pros and cons

Pros: Unlimited invoices and customers at 0.00 USD per free make costs straightforward as billing volume grows.
Pros: Estimates, recurring invoices, partial-payment records, reminders, and a customer portal cover much of the billing and collections workflow.
Pros: Expense tracking and sales, tax, overdue-balance, and profit reports extend it beyond invoice production.
Cons: Self-hosting requires a compatible PHP, web server, and database environment, placing setup and operation on the user.
Cons: Webhooks are still coming soon, limiting fit for workflows that rely on event notifications.
Cons: The described MCP capability is tied to an alpha release and must be enabled by a super admin, so it is not a ready-made default for every installation.

Verdict

InvoiceShelf is best for a small business, agency, or consultancy that wants a capable invoicing and expense system without a subscription and has the means to self-host it. Unlimited invoices and customers, recurring billing, and payment tracking are persuasive strengths at 0.00 USD per free.
