Starting Amazon Canada Bussiness

Hello there, I am starting a new amazon bussiness with a friend. We are both a full time employees and we decided to invest some of our savings to “try” to see if we are good in selling in Amazon, so we are taking it slowly and only investing a very small amount of money. We registered a bussiness name in ontario and made a partnership account on amazon canada. I am wondering how the finances should be managed to make it easy for us when we do the taxes:

• we are planning of having the revenue reinvested in the company and not pay our selves a salary or bonuses until we really need it. Is there a better way to lessen our taxes?

• Currently the revenue goes to one of our personal bank accounts. When we file for taxes next year, will we be asked to declare the taxes for the bussiness or to include the taxes in our personal filing.

• anyone has other tips for the finances? (Grants, free resources, other advices?)

P.S. not familiar with bussiness and finance terms so please talk to me like you are explaining to a child. Thank you!
