Fatture Geometri is a free app designed to help freelance architects and engineers create invoices, pro-forma invoices, quotes, and receipts. This Android-based app offers several features, including calculation of invoices, pro-forma invoices, quotes, and receipts based on the taxable amount. The app also provides reverse invoicing (VAT deduction) based on the total taxable amount, reverse invoicing (VAT deduction and contributions) based on the total invoice, and reverse invoicing (VAT deduction, contributions, and IRPEF tax withholding) based on the total expenses incurred by the customer. Fatture Geometri also offers invoicing for substitute tax-paying clients, such as companies, firms, and individuals.

The app is compliant with the updated 2022 regulations and provides a manual setting for VAT rates, calculation of stamp duty, and the inclusion of non-taxable expense reimbursement. Fatture Geometri also provides split payment VAT (payment splitting) and offers settings for Italian, European, and extra-European clients. The app's free version has ads, and there is a paid version (Fatture Geometri Pro) that offers additional features, including the ability to save PDFs and send them via email.
