What should be the entry of Owner investment when he start the business and which voucher is to be made ?

Cash (DR); Capital or Equity (CR)

General Journal 

****dr/bank

****dr/car

****dr/furniture

*********cr/capital

opening entry 

I think Cash/Bank Account to be debite because it gain in any source . and Owner's Equity account should be credited with same amount as it gain libilty .

Receipt Voucher is not require because there is no second party .

Owner himself investing in his own business so journal entery is enough and suporting documents require ( legal documents ) as proof
