Documents Required When Selling Online: Which 5 Will You Need to Prepare?

documents required when selling online

Selling your products or services online is a proven strategy that will be at the heart of your plans to launch or grow your business. Naturally enough, before you start accepting payments and shipping orders, there are some essential documents required when selling online that need to be provided and verified.

If you have exciting plans for your eCommerce store you don’t want those ambitions thwarted by a lack of compliance and documentation. Make no mistake, having the right documents prepared will make the process smoother and help you comply with key legal and payment processing requirements.

One of the essential details you will need to provide includes a Social Security number, which serves as a reliable indicator of your taxable status and provides certain assurances relating to your identity. Even if you can’t provide this information, you can still create a payment gateway without SSN data if you use a specialized provider.

Let’s look at that scenario, and other essential documentation requirements you’ll need to prepare and satisfy before becoming an online merchant.

📖 Key takeaways

  • You’ll need to prove your identity with a government-issued photo ID to open accounts and start selling online securely.
  • We recommend having your Social Security Number or an alternative tax ID ready to keep your business compliant with tax authorities.
  • Don’t forget to prepare your business formation documents if you operate as an LLC, corporation, or partnership—these confirm your legal business status.
  • Make sure you check whether you need a business license or seller’s permit based on your business location and the products you sell.
  • You’ll want to provide accurate bank account details and proof of ownership to ensure smooth payment processing and avoid delays.

1. It starts with proving your identity

It stands to reason that you will need to be able to prove your identity to open an account and start trading online. This will typically be in the form of a government-issued photo ID such as a driver’s license or passport.

Payment processors and online marketplaces use this data to verify who you are and to comply with anti-fraud measures and so-called “Know Your Customer” regulations. If you’re running your business as a sole proprietor, this will often be linked directly to your personal details. For incorporated businesses, you may also need to provide identification for the company’s directors or beneficial owners, as well as the legal name of the company and its directors.

Including your job title in your account or profile can help establish credibility and streamline the verification process.

2. Your SSN will often be required

Another common request will be to provide your Social Security Number (SSN) if you’re a US citizen or resident.

This is regularly used by payment platforms to verify your identity and to report your earnings to the IRS for tax purposes. Sellers are required to pay taxes on their online sales income, so understanding your tax obligations is essential.

If you don’t have a Social Security Number, which is feasible if you’re a foreign seller or a non-resident, you may need to obtain an Individual Taxpayer Identification Number. Alternatively, a way around this would be to use a specialized payment provider that caters to international merchants and doesn’t require an SSN for account setup—some of these providers also offer free resources or tools to help with tax compliance.

3. Prepare your business formation documents

Next on the list is business formation documents, if you’re operating as a registered business rather than as a sole proprietor. You may need to provide company registration details as part of your business formation documents.

If you have an LLC, corporation, or partnership, for instance, you’ll need to provide articles of incorporation, a certificate of formation, or details of partnership agreements.

Supporting documents, such as a letter authorizing a representative to act on behalf of the company, may also be required for verification. These are used to confirm your business’s legal structure and ownership, which payment processors and banks require for compliance.

4. Check your need for a business license or seller’s permit

Another important step is to have your business license or seller’s permit ready for inspection. Local governments are responsible for issuing business licenses and permits for online sellers, often through their official online portals.

When applying for these licenses, you may need to provide documents such as proof of address or business registration, ensuring they are accurate and properly formatted. What is needed will depend on your location and what you’re selling.

For guidance, most states require online sellers to register for a sales tax permit so they can collect and remit sales tax. Even if you operate only online, your state or city may have rules requiring a business license.

5. Provide bank account details and proof of account ownership

Payment platforms need this data so that they can use it to transfer funds from sales directly to your account. Another reason they require proof is to help prevent fraud or misdirected payments.

Once you have navigated these essential document requirements you’ll be ready to start selling online, knowing you’ve met your legal and operational obligations.
