Pocket Invoice

Pocket Invoice is a free invoicing workspace for freelancers and small businesses. Create invoices, estimates, quotes, receipts and purchase orders, keep customer and item records, export PDFs and track paid or unpaid invoices. Saved records are shared across the web, iOS and Android apps. There are currently no subscriptions or paid plans; account, document and storage limits apply. The public online document generator can create a PDF without an account. Saved business records and the optional hosted MCP server require an account. The MCP server supports Streamable HTTP and OAuth and has been tested with Codex. An authorized assistant can find customers and items, create invoices or estimates, apply company templates, generate PDFs and check unpaid invoices. Other clients need compatible remote MCP and OAuth support. Email sending is disabled by default and requires confirmation for each send. The service does not charge cards or transfer funds.
