  • All letterheads, invoices, bills or other documents used for the purposes of doing business have the sole proprietorship’s registration number listed

  • Limited capital or expansion options as investors are often hesitant to deal with non-incorporated entities

  • All changes to the particulars of the business must be lodged with the Registrar within 14 days from the date of change

  • Quick and easy set up

  • No need to audit accounts or file annual returns with ACRA.

  • Simple business structure, the owner is the sole decision maker.


  • Unlimited liability. Owners are personally liable for all debts and obligations and therefore personal assets are at risks. You may want to avoid setting up as a sole-proprietor if your business involves high risks such as offering term payments to clients.
