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.

What is a Resale Certificate?

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.

Why You Need One

  • Show you’re a legitimate business buying for resale
  • Avoid paying sales tax on your B-Stock purchases and pass those savings on to your customer
  • Allows you to buy more merchandise to grow your business

What’s Included on the Certificate

A resale certificate typically includes:

  • Your business name and address
  • Your sales tax ID or number
  • A brief description of the goods you buy for resale
  • Seller information (leave blank on B-Stock, since you’ll buy from multiple retailers)
  • A statement that goods will be resold

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.

CA seller permit number
How to Get a Resale Certificate

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.

If you’re located outside of the US, we cover applicable tax documents here. → International Buyer Registration

Once you get that resale certificate, you’ll be on your way to purchasing inventory for resale in no time! Already have a resale certificate? Follow these instructions to add your certificate to your Buyer Profile. Need a quick start guide for getting registered? We’re glad you asked!

 

You may need a separate resale certificate depending on where you plan to ship inventory. Sometimes, one resale certificate may be eligible for additional ship-to states. Learn more here.
