Invoicerr
What Invoicerr is
Invoicerr is open-source invoicing software for preparing quotes and invoices, recording payments, and e-invoicing to tax offices. Its document tools also cover credit notes, purchase orders, and expenses. Clients can review and sign quotes online using a one-time code; quotes can request deposits or be split into instalments. Imported bank statements can be matched against payment references and amounts. Project time tracking covers billable and non-billable hours, with a way to invoice unbilled time in one step. A client portal gives customers access to documents, balances, PDFs, online payments, and quote decisions. For supplier bills, self-hosted OCR turns received invoices into editable proposals that can be approved or rejected.
The product includes a built-in MCP server, a REST API, and 18 webhook events scoped by API key. It lists country-specific tax and e-invoicing details for Germany, France, Italy, Poland, and Portugal, along with 18 interface languages, recipient-specific document language, multiple currencies with rate history, and a hashed legal archive for sent invoices for the retention period required by the selected country. Invoicerr is available on the web, Linux, and through self-hosting and its API. The self-hosted plan costs 0.00 USD and includes all features, unlimited seats and companies, a Docker image and Helm chart, and community support. Cloud is listed at $23 a month, for three seats, per company; it is scheduled to open in November 2026.
