The permanent presence of an accountant in a small company is not important! You can get an accountant to attend once a week with a little amount to prepare the accounts, and so on.
The benefit of this is to have an excellent knowledge of the expenses and all matters related to your business, in addition to profit and loss.
Many companies think they are winning because they earn 200% with each sale without taking the operating price, like employees and rent, into consideration. So, owners pay salaries and employer spends their money. However, after a year, you can see the owner is surprised by the accumulation of debts! Despite the fact that they were not spending from their money, or the consumption of some employees may be more than their income.
In these cases, the accountant lets you avoid these things.
