Our verdict on Invoicerr
Invoicerr is an open-source invoicing application for freelancers and small businesses that need quotes, invoices, payments, expenses, client documents, and project-time billing in one system. It can record billable and non-billable project hours, then turn unbilled time into invoice lines. The client portal includes documents, balances, PDFs, payments, and quote decisions, while e-invoicing, multi-currency workflows, email delivery, and bank-statement payment matching extend its billing focus. It suits self-hosters who want control over deployment, as well as teams that prefer a vendor-hosted cloud option.
Platform fit is a central strength. Invoicerr runs on the web and exposes a REST API, outgoing webhooks, plugins, and an MCP server for AI-assisted quote, invoice, client, and article creation. Self-hosting is supported through Docker, docker-compose, and Helm, with PostgreSQL and SQLite listed among its integrations. The self-hosted plan includes every feature of the app, unlimited seats and companies, and an AGPL-3.0 license. Cloud is hosted and updated by Invoicerr, includes every feature of the app, offers a 14-day trial, and provides data export when leaving. A free plan is also available, making the product suitable for evaluating its core workflow before choosing a deployment model.
The product’s center of gravity is invoicing rather than specialized time management. Its published capabilities clearly cover recording project hours and billing unbilled time, but buyers seeking deeply defined time-entry controls, approvals, rate assignment, or expense-billing workflows should compare it with a time-tracking-first alternative. Invoicerr is a strong match for self-hosters who need invoices, quotes, portals, payment matching, and extensibility, especially when unlimited seats and companies matter. Choose another category fit if advanced time operations are more important than open-source deployment and broad billing workflows.
