The main distinction between Sole Proprietors and Partnerships and Limited Companies in bookkeeping terms is the treatment of the funds used to finance the business - the capital.
Sole Proprietors and partners have a capital account - the private funds they have put into the business. It usually has a Credit balance as it is money owed by the business to its owner (a liability of the proprietorship or partnership).
During the year, proprietor or partners may contribute more funds, which will be Credited to the Capital account. Similarly the owner(s) may draw a 'wage' or use business funds for private expenses, which are known as "drawings". These will be Debited to the Drawings account.
Profits/losses for the year are added to the capital account each year based on the formula in the partnership agreement.
