Software built around your business
Off-the-shelf tools force your team to adapt to someone else’s idea of how work should be done. Spreadsheets and manual workarounds don’t scale. Custom software is built around your processes instead.
Bitter Works is a software development agency based in Asunción, Paraguay. We’ve built software for consulting firms, business groups, real estate and travel companies, and our team brings more than 6 years of experience working with companies in the US and Europe.
Why build custom software
- It fits your process, not the other way around.
- Everything in one place: customers, sales, inventory, bookings or whatever your business runs on.
- It connects to the tools you already use through APIs.
- It scales: new features can be added as your company grows.
“Today I manage my entire business with the custom system they built for me.” — Karina Buitrago, Bitter Works client
Nearshore development from Paraguay
Working with a team in Paraguay gives US and European companies a nearshore partner with strong time zone overlap, communication in English or Spanish, and competitive rates.

Frequently asked questions
What kind of software do you build?
Web applications, mobile apps, custom business systems, online stores, landing pages and API integrations between systems. If a process in your company runs on spreadsheets or manual work, it can probably become software.
Do you work with companies outside Paraguay?
Yes. We're based in Asunción and our team has more than 6 years of experience working with companies in the US and Europe. We work remotely in English or Spanish.
What time zone do you work in?
Paraguay is in the UTC-3 time zone, which overlaps most of the US working day, so real-time calls and collaboration are easy.
How long does custom software take to build?
It depends on scope. A landing page is quick, while a full platform is planned in phases. After the first meeting we send a proposal with a timeline.
Do you provide support after launch?
Yes. We offer ongoing support and maintenance: bug fixes, updates, improvements and new features as your business grows.
