Montana-founded business services firm bundling PEO co-employment with accounting, recruiting, marketing and managed IT
Avitus Group is a PEO that quotes companies of 10 to 150 employees (sweet spot: 15 to 75), most often Montana, Rocky Mountain and Pacific West small businesses. Montana-founded, independently held since 1996, and one of the few PEOs that also sells accounting, recruiting and managed IT under the same agreement. Neither IRS CPEO certified nor ESAC accredited, and it publishes no scale figures, so finance-led buyers will need to do their own diligence.
Our take
Avitus Group is worth a look for small employers in Montana and the Rocky Mountain West who want one vendor for payroll, HR and the parts of the back office most PEOs do not touch, including accounting, recruiting and IT. That bundling is a real differentiator for an owner with no internal administrative team, and the firm has been independently held since 1996 rather than passed between sponsors. What we flag is the credential stack: no IRS CPEO certification and no ESAC accreditation, which means neither the federal tax-liability shift nor bonded financial assurance is on the table. We also push for hard numbers on worksite employees and master medical participation before signing, because the company publishes almost nothing about its own scale.
