Context

You may need to update billing information such as company name, address, or tax ID on an invoice that has already been issued. This commonly occurs when billing details weren't updated before a payment was processed, or when invoices need to reflect a different organization for accounting purposes.

Answer

Unfortunately, billing information cannot be directly modified on invoices that have already been issued. However, our support team can help by refunding the original invoice and reissuing a new one with the correct billing information.

To request this change:

1. Update your billing information in LangSmith first: Go to Settings > Usage and Billing > Plans and Billing > Additional billing information and make sure all details are correct. Documentation is available here.

2. Contact support: Reach out to our support team with your request, including the invoice number(s) that need to be updated and the correct billing information you want reflected.

3. Invoice reissue: Our team will refund the original invoice and generate a new one using your updated billing information. You'll receive both a credit note for the refund and a new invoice via email.

Important notes:

• Make sure to update your billing information in LangSmith before requesting the invoice to be reissued

• The process involves a refund and recharge, so you may see both transactions in your payment records

• Future invoices will automatically use the updated billing information once it's corrected in your account

• Invoices are only available in PDF format

For assistance with this process, contact our support team at https://support.langchain.com/ with your specific invoice details and updated billing information.
