What the free tools do not do
They keep nothing. Every certificate starts from a blank form, we cannot re-send one you have lost, and there is no record to reissue. That is fine for the occasional job. If you are doing several a week, an account remembers your details and your customers, keeps every certificate, and gives each one a link for the landlord.
