Who writes and checks these guides

Guides are written and maintained by the SayInvoice editorial team. Product statements are checked against the dated SayInvoice product evidence register, while tax and legal points link directly to official guidance. No accountant, tax adviser, solicitor or other qualified human reviewer is credited unless their identity, qualification, review scope, review date and permission to be named have been supplied and recorded.
