assuming the business is taxed as a sole proprietor or partnership, deposit the funds and use owner equity investment as the source account for the deposit
For a company taxed as a sole proprietor (schedule C) or partnership (form 1065), I recommend you have the following for owner/partner equity accounts (one set for each partner if a partnership)
[name] Equity (do not post to this account it is a summing account)
>> Equity
>> Equity Drawing - you record value you take from the business here
>> Equity Investment - record value you put into the business here
