# Invoice AI > Invoice AI is invoicing software for freelancers and one-person businesses. > You create an invoice by speaking to your phone — the app understands natural > language — and artificial intelligence handles the rest: sales forecasting, > debt recovery, cash-flow projection and custom reports. Available on iOS and > Android, in English, Spanish and Brazilian Portuguese. Invoice AI is made by Smart Tech Software, LLC, a mobile business solutions company founded in 2008. There is a free plan; paid plans start at $2.95 per month. Pricing is public and machine-readable at /pricing.md — no sales call is needed to see it.

Commands include Create, Modify, Delete, Search and Adjust, and it also accepts full sentences such as "Invoice Juan for 10 boxes". - **Payment tracking.** Send PDF invoices and follow what has been paid. - **AI reports.** Ask questions about your own numbers in plain language. - **Sales forecasting, debt recovery and cash-flow projection.** - **Daily backups**, including on free accounts. - **Offline-first**: the app works without a connection and syncs afterwards. ## Pricing - [Pricing in plain text](https://www.invoice-ai.cloud/pricing.md): every plan, its price and its limits, in a file made to be read by machines. - [Pricing section on the site](https://www.invoice-ai.cloud/#pricing): the same figures, rendered server-side, always current. ## Pages - [Home — English](https://www.invoice-ai.cloud/) - [Inicio — Español](https://www.invoice-ai.cloud/inicio.php) - [Início — Português (Brasil)](https://www.invoice-ai.cloud/inicio-pt.php) - [Benefits](https://www.invoice-ai.cloud/benefits.php): what the app does, feature by feature. - [Privacy and terms](https://www.invoice-ai.cloud/privacy-terms.html) ## Blog Articles on invoicing, getting paid, and how artificial intelligence changes the way a small business bills.
