About

A US company building serious software

RTH Systems, Inc. builds and runs business software for US companies, with a focus on bilingual tools that work as well in Spanish as in English.

RTH Systems was founded by accountants who got tired of the same thing their clients complained about. Small businesses were paying more every year for accounting software that still could not handle a second company, still charged extra for payroll and 1099s, and still treated Spanish as an afterthought.

So we built a better mousetrap. Our accounting platform, Your Books USA and Tus Cuentas USA, runs multiple companies on one flat price, files 1099s straight to the IRS, handles Florida and multi-state sales tax, and works in full English and full Spanish. It is built on open standards, which means customers are never locked in and always own their data.

From there the work grew. Clients asked us to host their other systems, connect their CRM, and build custom tools. Today RTH Systems is the platform, the host, and the developer for the companies we serve, all on infrastructure we control and secure ourselves.

What we care about

Two languages, one product

English and Spanish speakers get the same tools, not a watered-down translation.

Your data is yours

Open standards and clean exports. You are never trapped.

Built for US rules

1099s, sales tax, and payroll are core, not add-ons.

Work with us.

Whether you need books, a full ERP, or something custom, we would like to hear from you.
