The People Behind Agvance
Located in the heart of agriculture in Central Illinois, we’re developing technology and ideas that help make agriculture more productive and sustainable. We are passionate people who willingly embrace challenges and continually strive for solutions. We celebrate collaboration and encourage each other to think outside the box. At the end of the day, we love what we do – helping ag retailers become more successful.
We know choosing the right software platform is an important decision. Selecting the right company to work with is just as important. Here’s what sets SSI apart:
Our Roots Are in Agriculture
It’s who we are and where we come from. Our company was born from a single co-op that needed a more effective, user-friendly system. We believe easily accessed information makes ag retailers more efficient and productive, and this simple belief continues to drive us.
We’re Committed to Improving Agriculture
Through leading-edge thinking, our software solutions are helping to influence an ever-growing, data-driven industry. By embracing leadership roles, through AgGateway and other channels, we are working to positively affect the industry and move it forward.
We’re the Trusted Leader in Ag Retail Software
With over 30 years of experience, we’ve gained the expertise, knowledge, and insight to discern a company’s challenges and provide it with the best solutions. This extensive experience, combined with our familiarity of the industry, allows us to continually develop and deliver the most effective systems for agricultural retailers.
