Payments received — every payment recorded against an invoice, including applied retainer credit. Record one from the invoice list (Payment button) or a customer profile.

Chart of Accounts is the ledger backbone: income accounts receive invoice revenue (via each service's mapping), expense accounts categorize bill lines, and the balance-sheet accounts are here for your bookkeeper. Archive what you don't use — archived accounts disappear from pickers but stay on history.

Services are the verticals offered on invoices. Add new ones below, rename or re-map them to an income account any time, and archive what you no longer sell — archived services disappear from the invoice editor but stay on historical invoices.

How access works: anyone can attempt Google sign-in, but only emails listed below can actually see or touch data — enforced by the database itself. Add a member with their Google email \u2014 or with just a username + password (no email account needed; they sign in with the password form). staff can create and edit everything but cannot delete records; admin can do everything including managing this list. Removing a member cuts their access immediately.
