InvoicePlane: An Overview

InvoicePlane is a free, open source invoicing application that manages quotes, invoices, payments, and customer records. It is intended for small businesses, freelancers, and agencies that want control over their billing data through a self-hosted solution with customizable templates and client management features.

Compared with hosted accounting and invoicing services such as FreshBooks, QuickBooks Online, and Wave, InvoicePlane is not a hosted SaaS product. Unlike those services, InvoicePlane requires you to host and maintain the application, which removes subscription fees and gives greater control over data and customization. While FreshBooks and QuickBooks include integrated bookkeeping, bank feeds, and vendor support, InvoicePlane focuses tightly on invoice lifecycle and client management with the ability to extend via community plugins.

InvoicePlane does well at delivering a straightforward, privacy-friendly billing stack for teams that can manage their own hosting. Its strengths are cost transparency, template customization, and a community-driven extension model, which makes it particularly suitable for users who want a lightweight, configurable invoicing system without ongoing subscription costs.

How InvoicePlane Works

InvoicePlane runs as a web application on your server or hosting account, using a PHP stack and a database backend. After installation you enter company details, create clients, and produce quotes that can be converted into invoices; invoices can then be marked as paid manually or via connected payment gateways.

The typical workflow follows a simple sales to cash cycle: create a quote, convert to invoice upon approval, send a PDF by email, and record payments. Administrators configure tax, currency, PDF templates, and email settings once, then reuse templates for recurring clients and line items. For community-driven issue tracking and code changes, contributors use the project’s official GitHub repository and the issue tracker to discuss bugs and pull requests.

InvoicePlane features

InvoicePlane centers on billing and client management, with core capabilities including quote and invoice creation, PDF generation, payment recording, client CRM fields, theme and template customization, multilanguage support, and online payment gateway integration. Since version 1.6.2 it also supports creation of eInvoices aligned with European e-invoicing standards.

Quotes, invoices and eInvoices

Create and manage quotes and invoices with configurable number sequences, tax rules, and itemized lines. Invoices export to PDF, can be emailed from the app, and can be converted from quotes with a single action; eInvoice creation enables compliance with EU e-invoicing formats starting in recent releases.

Client management and CRM fields

Store contact details, notes, and custom client fields to keep billing-related client information centralized. The client area supports multiple contacts per client and basic project/task metadata so you can link invoices to client records and track billing history.

Customization and templates

Choose from themes and modify PDF and email templates to match branding and regional formatting. Template editing allows control over layout, custom fields, and amount formatting so generated documents meet business and legal presentation needs.

Online payments

InvoicePlane integrates with popular payment gateways such as PayPal and Stripe to accept one-click online payments. Payment gateways are configured in settings so customers can pay invoices via embedded payment links, reducing manual reconciliation work.

Multilanguage and localization

The interface is translated into multiple languages by community contributors, and currency and number formats can be adjusted per installation. Localization settings help when invoicing clients across different regions and complying with regional invoicing conventions.

Community and open source support

The project is driven by a community that provides support on forums and chat channels, contributes translations, and files issues or pull requests on the project GitHub. Community contributions also include plugins and extensions that expand payment gateways and integrations.

With these features, InvoicePlane delivers a compact invoicing platform that prioritizes document control, template flexibility, and self-hosted data ownership, making it a practical choice where subscription costs or data residency are concerns.

InvoicePlane pricing

InvoicePlane is free and open source software, distributed for self-hosting, so there are no subscription plans for the core application. You can download and run it on your own server without licensing fees, and the source code and issue tracking are available from the official GitHub repository.

While the software itself is free, organizations should budget for hosting, backups, maintenance, and optional paid services such as managed hosting or third-party integrations. For installation steps and configuration guidance consult the installation and configuration guide in the project wiki.

What is InvoicePlane Used For?

InvoicePlane is mainly used to produce and manage quotes and invoices, to track payments, and to maintain a simple CRM of clients and contacts. Small businesses use it to centralize billing documents, generate branded PDFs, and keep an auditable history of invoices and receipts.

It is also used by agencies and freelancers who prefer to control their billing environment, customize templates to match client contracts, and avoid recurring SaaS fees. Developers and IT teams deploy InvoicePlane as part of a self-hosted stack and integrate it with internal systems through community modules or the available developer APIs.

Pros and Cons of InvoicePlane

Pros

  • Free and open source: The core application has no licensing fees and can be self-hosted, giving full control over data and upgrades. This keeps recurring costs low and avoids vendor lock-in.
  • Customizable templates and themes: Templates for PDFs and emails can be edited to meet branding and legal requirements, allowing businesses to control invoice presentation precisely.
  • Lightweight and focused: The interface is focused on billing tasks, which keeps workflows simple for users who do not need full accounting suites.
  • Active community support: Community forums, chat channels, and the GitHub repository provide a place for troubleshooting, feature requests, and contributions.

Cons

  • Self-hosting required: You must manage hosting, backups, security updates, and server configuration, which adds operational overhead compared to hosted SaaS offerings. This can be a limitation for teams without technical resources.
  • Limited built-in accounting features: InvoicePlane focuses on invoicing and client records rather than full bookkeeping, bank reconciliation, or payroll, so additional tools may be necessary for complete accounting workflows.
  • Fewer official integrations: Payment gateways like PayPal and Stripe are supported, but deep integrations with bank feeds, tax services, or enterprise ERPs are typically handled through community plugins or custom development.

Does InvoicePlane Offer a Free Trial?

InvoicePlane offers a free, open-source version for self-hosting. There is no trial period because the application can be downloaded and installed at no cost; users test it directly by installing on a local or hosted server and configuring sample data to evaluate features.

InvoicePlane API and Integrations

InvoicePlane provides developer-facing resources through its project repository and community plugins that extend functionality and add integrations. The project wiki and repository are good starting points for API information, installation guides, and available extensions.

Out of the box, InvoicePlane supports payment gateways such as PayPal and Stripe, and the community maintains additional connectors and modules that integrate with other services or provide custom import/export capabilities. For automation or deeper integrations, developers typically use the available endpoints and community extensions or implement custom extensions aligned with the project architecture.
