      Our company provides software as a service to some of the largest transportation companies nationwide. For over 16 years TJCO has been our trusted go to software developer. TJCO support and response times go over and above expectations. We appreciate their professional approach and look forward to working with them again on our next development project.

      I ordered the DNC scrub they never delivered. I am still waiting for my refund. Ordered on a Saturday got an email stating " our offices are closed we will reopen bla bla bla" After a few days of hassle they decided to refund however so far the money did not show up in my credit card. I don't recommend doing business with this company.

      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.
