The system is very bad. Developers should not intervene with how the accountants will handle and manage the chart of accounts and other accounting activities. You should design the system which will allow the users to change with ease. Another thing, You know already that companies do pay taxes. Some withholding agents (taxpayers) withhold or deduct a portion of money before they pay the vendor. I see it in India as TDS or Tax Deducted at Source. In our country, the TDS is just named as Withholding Tax, they why this cannot be setup in our country? This is so ridiculous, your are selling your product globally yet there's no freedom for customization. Before you market your product to different countries, you need to do some research, not just trying to make a dress for one that fits all!!
