Owner & Principal Consultant

Wayne Schulz

As the owner of Schulz Consulting and a Non-Practicing CPA, my focus is simple: provide expert, fixed-fee Sage 100 support that delivers results.

I specialize in helping wholesale distributors with everything from complex troubleshooting to providing a valuable second opinion on their systems.
