Why we recommend Amir
Amir (FactorBox) stands out for its straightforward approach to invoice generation, requiring no registration or installation. It prioritizes user privacy by storing all data locally in the browser's storage, never transmitting information to external servers. The app calculates VAT and discounts automatically, streamlining the invoicing process. Users can choose from various output formats, including A4, A5, thermal receipts, PDF, and Excel, catering to diverse business needs. Its support for integration with AI assistants via a free MCP server is a unique feature, enabling automated invoice creation and calculations. The claim of being a public utility and always free adds to its appeal, positioning it as an accessible tool for small businesses and individuals.
Best use cases
Best for: Small businesses and freelancers in Iran needing to quickly generate official, sales, or proforma invoices without complex software or registration. Ideal for users who require automatic tax and discount calculations and want to print invoices in various formats, including thermal receipts. It's also suitable for those who prioritize data privacy, as all information is stored locally, and for users looking to integrate invoice creation with AI assistants.
Honest limitations
Amir is not designed for advanced accounting needs or managing complex client databases beyond local storage. It does not replace electronic invoicing systems for submitting reports to government tax platforms. While it generates official-looking invoices, it's explicitly stated not to be a substitute for the electronic invoicing required by the 'Samane Modayan' system. The app's primary focus is on quick, client-side invoice generation, not comprehensive financial management.
