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.

Salesforce Review from Rishi Kumar
I had the opportunity to work with Accenture on implementing Salesforce with ServiceMax. Their expertise and dedication were impressive. Accenture's work on implementing Salesforce and the ServiceMax managed package was invaluable, significantly benefiting our organization's operations and efficiency. However, one area for improvement would be the documentation process. It was challenging to access comprehensive documentation, which slowed down certain aspects of our project. Nonetheless, I recommend Accenture as their talented team delivers exceptional results.

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.

RA's Review Sourced from Google
As an accounting firm I would give them 1 star. I recently discovered a litany of deductions they failed to consider. You will be given an EA, which is just a glorified tax preparer. They will know nothing and be slow to reply. You might as well get your taxes done by H&R block or a proper independent CPA. If these folks do your taxes, get prepared for a larger tax bill. I strongly advise against it.

I am giving this company 2 stars...1 star is because they do an ok job. The other star is for when we tried to cancel they said fine but no one told us there was a 30 day cancellation and we had to pay for the month we cancelled/never used them. Buyer Beware!

I chose St. Louis Digital based on their long-standing reputation in my market. As a new franchise owner, I initially faced challenges with advertising effectiveness. However, upon the recommendation of St. Louis Digital, we transitioned from our corporate website to one of theirs. The result has been outstanding – within just seven days, we received more phone calls than we did in the entire month of July. The team at St. Louis Digital is responsive, professional, and I highly recommend their services.
