We are using poyrty for more than 3 years now in our organization as external auditor of one client's financials which is very large scale transaction where we need to have high level data accuracy assurance.
Their team has always been professional at all times even when their project was not going well with us but they were still there trying hard every day till it gets done right! Nothing so far!! You should go ahead if you want your transactions audit checked by best auditors available out here. They will make sure everything goes smooth no matter what happens within this process because they know how stressful can be dealing with such things otherwise would give up easily especially during recession time like these days! Data integrity checks /assurance/audits etc.
