The (usually) technically correct response is that your company will reimburse you in your home country.

My father-in-law is a salesman for women's apparel. Two of his largest lines are based in Canada, so he has to go there at least twice a year for sales meetings. However, his reimbursement is entirely covered by their US subsidiary. It's a working visa, but granted on entry and prohibits work that will be paid for in Canada (e.g., he can take orders for products that will be shipped to the US, but not for those that will be shipped to Canada).
