So you’re ready to start your reselling business and make money online—great! Before you can begin bidding or buying on B-Stock, you’ll need to submit a resale certificate (or your country’s equivalent) as part of your registration.
A resale certificate proves you’re purchasing inventory for resale, not personal use. It allows your business to buy goods tax-free–it’s then your responsibility to collect this when you resell to customers.
A resale certificate typically includes:
Depending on the country, state, or province your business is registered in, it might also be called a reseller’s license, sales tax exempt certificate, business tax ID number, seller permit number, sales tax certificate number, or sales tax ID number.
During registration, this will be referred to as your reseller tax ID. See example below.

Each state manages resale certificates differently, so start by visiting your state’s Department of Revenue website. There, you’ll find instructions on acquiring a sales tax number in your area. Remember, as a buyer, it’s your responsibility to do your due diligence and comply with federal and state laws.
Here are a few helpful resources:
Note: Resale certificates are not required if your business is based in Alaska, Delaware, Montana, New Hampshire, or Oregon.
