How does “Supplier credit accounts” work on the Form Fill page?

A supplier's application is filled from the company's saved details and signature, and the supplier's form is kept with its fields placed so the next company opening an account there picks the company and skips the upload. The filled form is emailed to the supplier from here; the row says Emailing until the server confirms and Emailed after. Supplier forms belong to the accounts team and are visible to everyone who may read invoices; the other kind of form is private to its author, and an Owner or Admin is not exempt from that. Where: Form Fill (/accounts/form-fill).
