Make an invoice or estimate in a minute and download the PDF. No account and no server copy: documents are saved in your browser, with a backup file you can export and import. Works offline after the first visit and installs like an app. 56 currencies, your own tax names and rates, documents in 17 languages including right-to-left Arabic. The free version has no time limit; an optional Pro version adds saved clients and items, search, overdue overview and templates. Not a certified e-invoicing system.
