Accounting Review from Dmitrii Legetskii
This company helped us set up our accounting system from beginning to end. I am a serial entrepreneur with experience working with many different accounting groups and this one has been the most responsive overall. They have helped us with registering the business, putting together payroll, and getting our quarterly tax returns filed. They have been also very helpful with giving personal tax advice. I would recommend them to any other friends and especially other business owners.

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.

Abdalla Abdelrahman's Review Sourced from Google
Their after-sales support has been extremely disappointing. Despite multiple attempts to contact them, my emails have gone completely unanswered. I requested a paid extension for lab access, yet my request has been entirely ignored - even after investing over $2,000 in their training course. This level of service is unacceptable.

I've had my ups and downs hiring various IT professionals to assist in our tech operations. A trusted friend recommended this firm, and since then, I haven't looked back. Dealing with ITAdOn has been delightful; they have been our most reliable partner so far, and no provider I've ever hired has come close in terms of responsiveness, accountability, and professionalism.I've achieved great results with them, receiving fantastic IT support and meeting our recruiting needs. Huge thanks to the ITAdOn team for helping us scale our business.

I have been very satisfied with the IT Support we have received from ITAdOn. ITAdOn has helped us build a secure IT infrastructure that gives us peace of mind (especially where there are a lot of cybersecurity and ransomware risks nowadays). Every staff member is very competent, responsive, and easy to work with. They treat us like their own and do whatever it takes to properly get the job done. The team members at ITAdOn are truly the professionals you want on your team helping you out when your technology snags an issue. Knowing I can rely on them, they are our go-to IT support company here in Philadelphia! I highly recommend them.

ITAdOn has been managing our IT infrastructure for the last few months and we couldn’t be happier. The technical support team is very responsive and extremely knowledgeable. I feel great that our network, server, and our workstations are up to date and running smoothly. They recently upgraded our workstations to Windows 11 which was effortless on our end and everything is working seamlessly. Very happy with their service.
