Benefits of an integrated approach

We assign engineering oversight to the design process to ensure engineering feasibility and budget alignment.

Our nearshore development office in Buenos Aires, Argentina, grants us access to top-tier English-speaking resources at roughly 50% of the cost of US-based resources. But it’s merging the two in a “blended team” model that really makes AccelOne stand out. Our model allows us to employ a local software architect to lay the framework while leading a team of custom software developers in Argentina. It also enables us to hire a specialty developer for your unique project — all at lower costs without sacrificing quality.
