Right after launching our campaigns with Disruptive, we saw results almost instantly. Our monthly revenue jumped from about $50,000 to over $70,000. Every key Google Ads metric improved, and by November, we were already nearing $550,000 in revenue, well on track to hit our $700,000 annual goal.

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.

Horrible experience with this agency. They wasted thousands of dollars on keywords not related to my business, failed to deliver accurate monthly reports, and my website had better SEO results before they started. I was on page 1 for my most important keyword, and am now on page 3 in a six month period. My account was passed on to 3 or 4 separate reps due to employee turnover and I was constantly reeducating people about my company and goals. My business was better off with Reach Local! Thankfully I only signed a 6 month contract, I don't know if my business could have survived an entire year of Advantix induced set backs.

I they do not care about their customers!I have been with them for over 40 years! I was just notified I was no longer wanted as a client.I called and text 3 people I knew there, asking why they were canceling my simple tax account.NO ANSWERES. Then a month later I got an email saying they were down sizing!Is this how you treat a loyal customer of over 40 years that does a simple tax return? I always relied on this company and the people in it. I feel so disrespected. I would never trust them again.

Computer technology has vastly improved many of our lives, even in the non-profit world. The issues are cost, reliability and maintenance. It is too much for a small business owner to become an expert in these areas. I'm not even sure it is possible. Having a partner - a paid vendor, yes, but a still a partner that respects your budget, responds quickly to problems as they arrive, and proactively seeks to protect your network from crashes and malware is invaluable. We feel like we have that partner with Whittlesey Technologies. Every year we meet to discuss vendor agreements and performance. Whittlesey Technologies has never been considered for replacement. They are our partner.

They have also provided very responsive day to day support. We look at Whittlesey as a trusted partner and part of our team.

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.
