Mizar
ChatGPT pluginInvoice PDFs from your notes
Mizar creates invoices as PDFs from your notes, hours, or timesheets inside ChatGPT — a business-admin productivity tool for freelancers and small businesses. Use it to create an invoice from notes, generate an invoice PDF, or bill a client from a timesheet. Paste notes, hours, or a timesheet; Mizar structures the line items, checks common invoice fields (seller and client details, invoice number, dates, tax rate, payment details) and asks you for missing ones, calculates line amounts, VAT per rate, discounts, and the total with decimal arithmetic rounded to the cent, and renders a one-page invoice in English or German as a PDF and printable HTML with a download link. It is designed to use only values you provide — missing fields appear as visible placeholders on a document marked DRAFT. Please review each invoice before sending it. Invoice details are processed only to calculate and render the document and are not stored by Midchat; download links expire after about an hour. Limitations: does not send invoices, take payments, create structured e-invoices (XRechnung/ZUGFeRD), or give tax or legal advice, and does not confirm that an invoice meets the legal requirements of your country.
