You'll receive an email from Bootstrap themes once your purchase is complete. It looks like this:
If you've lost that email or need a replacement you can login to your account and click on your avatar in the upper right corner then tap Purchase > Order ID. You'll see all of the relevant details there.
If you never created an account, you can also use our redownload page to resend all of your order confirmation emails.
If you need an invoice with your VAT information or you can't access your previous invoices reach out to themes@getbootstrap.com and we'll get you squared away.
