Hi, My name is Abraham Soriano, i'm a Public Accountant. In my experience i have to write more than 100 of free writings to Mexican IRS. On those writhings I explain diferents bussiness process, mainly enforcement of some energies, gas and oil, meat, dairy, pharma laws and rules in México, and the most important is the explanation of Income Tax and VAT. Those writhings are very important documents because are a statement with sign of legal represent, also in many cases it's verify by CEO. One of those free writhings let me get a VAT Refund (aprox one thousand millons of mexican pesos) of one renamed company in energy field. I can write about Accounting, Taxes, Tax Reform, Bussiness Process, Billing. I would like to help you with this research.
