Office supplies are items the business uses to provide goods or services. Ex: drugs and medication used by a veterinarian; cleaning supplies used by a plumber; household supplies and food that the children use at a daycare, etc…
Office expenses are small items such as pens, pencils, paper clips, stationery, stamps.
If the expense is placed in the incorrect area it may alert the Canada Revenue Agency (CRA) to question the expense as per your kind of business. It may or may not make a difference in the deduction amount.
