eCommerce Review from Anonymous
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.

We’ve been working with Disruptive on a long-term PPC strategy, and they’re constantly optimizing campaigns and landing pages based on performance. They use Google Analytics to ensure accurate tracking, Unbounce for landing page testing, and run ads through Google and LinkedIn, with knowledgeable experts for each channel.

Mike Ritzema Review from Google
5.0★
Mike Ritzema's Review Sourced from Google
Before working with IMPACT, we were stuck trying to make marketing work on our own. I had read They Ask, You Answer (the previous version of Endless Customers) and believed in the principles, but doing it DIY wasn’t producing results. We were writing articles here and there, posting inconsistently, and missing clear calls to action. The content wasn’t building trust or generating the kind of sales opportunities we needed.That changed when we made the decision to get a coach. Working with IMPACT’s coaching team gave us the structure, accountability, and clarity that had been missing. They helped us understand how to create content that earns trust with potential buyers, draws them in, and positions us as the most preferred option they are considering. We learned how to align each piece of content with the buyer’s journey and give every article a purpose.The results have been measurable. In just one year, our website traffic grew by 18% at a time when many companies are seeing declines. More importantly, our sales opportunities nearly tripled and grew even more when we only count qualified trucking companies. That growth allowed us to hire a salesperson for the first time in four years, which freed our content manager to focus fully on building quality articles, videos, and new tools.The experience of working with IMPACT has been excellent. The coaching team brings accountability and guidance without overwhelming us. The conferences and community have also been a big part of our journey, giving us ideas, tools, and connections that make implementation easier.I would recommend IMPACT to any business that wants to stop guessing at marketing and start building trust that translates into real sales opportunities.

Jason Diller's Review Sourced from Google
I've been doing inbound marketing since 2010 and I can say that Impact is one of, if not the best, inbound marketing agencies in the country. They're great people that are highly skilled at their craft. I would recommend them to anyone with aggressive growth goals. Impact delivers great results and their team is as kind as they are smart.

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.

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

Paisley Crain Review from Google

Paisley Crain's Review Sourced from Google
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.

Peter Keast, Sr.'s Review Sourced from Google
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.

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.
