      Our company left Tandem HR when they hiked the prices in 2024. Apparently, they do not send employers, copies of W2's for companies that have left service. I'm supposed to reach out to each employee to get a copy. Nice job, for doing the one job you had.

      Tandem HR has done a great job maintaining the white-glove service we have come to expect over the years. The HR, Payroll, and Benefits experts that engage with our team feel like true partners rather than a third-party vendor.

      The quality support I receive from my contacts at Tandem HR is unbelievable. I don't even entertain outreach from other PEOs. Paola consistently goes above and beyond for Prevention First. She is always so pleasant, knowledgeable, responsive, and helpful! The rest of the team (Janet, Danielle, Jennifer, etc) is really great too!

      So sphiscated accounting systems I must say. For what? Never saw an irs payable in any return they asked me to prepare although I’m no licensed accountant. No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis. The roc building is beyond comprehension though, they even do SNL up or down stairs never got to see a show so I don’t know

      Deloitte completely failed implementation of Army IgnitEd, which led to thousands of service members paying out of pocket for education expenses. The circus that we watched unfold leaves me with zero confidence in the services that this firm provides.

      Graham Ebetsch's Review Sourced from Google

      We found ourselves in the hands of QBO after our previous accountant merged her practice with theirs. We didn't feel great about the process in working with them for tax prep and pursued other help after one year. Our new accountant caught a major error within minutes of scanning through our QBO filings which cost us well over $2,000 at the time.We followed up with their team to understand how an error like that could have happened. I was assured by the president that he would personally investigate; I never heard back.

      QBO has handled our accounting and tax work for 5+ years and done a great job. They are very responsive and attentive. If you need outsourced bookkeeping or accounting services, you'd be hard pressed to find a better option.

      QBO has been doing my personal and now my Company's tax work. I was dissatisfied with my previous CPA- and the difference over the past 5 years has been night and day. Extremely knowledgeable and responsive. Additionally we have outsourced my Business' bookkeeping service to QBO and have referred them to other friends/businessowners.

      Had to use Synchrony as part of a company I worked for. Very difficult interface on top of requiring multi verification every time you wanted to log in and not providing a way for users to opt out. Would not set up a way for copies of checks to be emailed so I wouldn’t have to deal with multi verification anymore.
