Businesses
Invoicing, bills, bank reconciliation, the ledger and the statements. If you have an accountant, you can engage them from inside your own workspace and end it the same way.
Accounting firms
A practice console over every client: the roster, who is staffed where, jobs and their deadlines, and a request inbox. Your firm keeps its own books in the same account, in a separate tab, so the two are never confused.
Students
A full workspace on a time-boxed free plan, with every feature a paying business gets. It is the real product rather than a teaching mock-up, so what you learn transfers.
Clients with portal access
Read-only access to the documents a company has shared with you, and a way to ask about one. No ledger, no reports, nothing about anybody else. If you have a portal sign-in, the help inside it is written specifically for you.
