How to show expenses from personal a/c for sole propietorshp

Hello everyone, I really confused in this matter of Sole Proprietorship. If Banks don't issue credit card on current account then how will I transact online in the name of my sole proprietor business? Because online purchases occur using my personal credit card.

Is there a provision where I can transact on behalf of my sole proprietor business so that my expenses can be shown as business expenses?

Please help me clear out this confusion!
