TradeForm lets businesses accept applications for customer accounts, such as trade or credit accounts, through a simple online form. It checks a business's details with Companies House and HMRC and sends the application to the business it is for.
If a business has sent you a link to apply for an account with it, please use that link. You are applying for an account with that business, not with TradeForm.
TradeForm is in a private trial and is not yet available to new businesses.
