Who we are
EliosTech, Inc. is a Chicago-suburbs technology consultancy based in Rolling Meadows. We take on the work that moves money, systems and crews: payments and banking integrations, banking business analysis, Finance ERP on Dynamics 365, new-domain builds, and IT for construction and trade businesses.
We work as business analysts, testers, developers, improvers and creators, so one partner can map the process, write the spec, test the change and improve it after go-live. When the pressure is on — red-tag tickets, escalations, go-live weekends — we choose the right thing for your business over the fast shortcut, document what changed, and leave you with a setup that holds.
How we work:
- One accountable lead — the person you scope with is the person who delivers and answers for it.
- Visible work — boards, written estimates and a steady cadence sponsors can follow.
- Clean contracting — C2C through EliosTech, Inc. preferred; scope and rate stated up front.
- Honest packaging — premium, ethical engagements with no black box and no scare tactics.
EliosTech, Inc. is an S corporation incorporated in December 2014, owned and led by John Eliopoulos. John's personal background and résumé live on his personal site, separate from the company.

Every client leader we work for runs their own world. The engagement type you choose tells EliosTech, Inc. where you want us: our scope of authority, what we own and where we stop. Vice-president–level ownership takes vice-president–level money; a narrow individual or external-consultant focus can carry significant discounts. Contracts set clear relationship boundaries, the work EliosTech offers your business is proprietary, and, like a monthly SaaS plan, service continues while it is paid.
Why companies hire Eliostech
You are not buying a ticket queue. You are buying one accountable owner who:
- Owns the outcome — specs, data contracts, UAT and release readiness, not just status updates.
- Works under pressure — red tags and escalations get the right fix, not the fast wrong one.
- Keeps work visible — boards, written estimates and a cadence sponsors can trust.
- Contracts cleanly — C2C through Eliostech Inc. preferred; W2 when the total package is strong. Senior BA / BSA bands ~$80–$200/hr; trades operating partnerships $12,000–$20,000/month.
