Thank you.
This is the requirement I got from the IRCC page
- if the applicant is self-employed, articles of incorporation or other evidence of business ownership, evidence of self-employment income and documentation from third-party individuals indicating the service provided along with payment details (self-declared main duties or affidavits are not acceptable proof of self-employed work experience).
You can use a bunch of documents to prove ownership of business and services provided
1. Do you have Salon's business documents like registration document with government, business licenses etc.?
2. Do you file taxes as a business and does those taxes have your name as owner?
3. Does your salon have a bank account which has salon's name as account holder and not your name? It can show money coming in to the account if you take online payments / credit card payments from customers
4. Does your salon have a website with services listed?
5. Does your salon exist on google maps? Yelp or any similar website? Does it have customer reviews there which can be seen?
6. Do you employees? Do you sign their pay stubs? Or have any other way of proving employees getting paid?
7. As you mentioned you can take letters from suppliers and also show transactions with them.
8. As you mentioned you can get some letters from your regular customers.
Self employments are difficult to prove but if you really own a business there are tons of documents to prove that you own a business. And if you are not doing everything cash to avoid taxes you will have enough electronic trail to prove business income, expenses, payments and taxes.
