What it does
Who a payment is for
A member is anyone a commitment is for: family, household help, a landlord, a tenant or a vendor. An optional tag gives their role, from longbook's list or typed in, such as Cook or Self.
What pays it
An account is what a commitment is paid from: a bank account, a credit or debit card, UPI, a wallet or cash. Each account Belongs to one member, or to No one in particular for a joint account.
One card per person
Each card counts a person's commitments and charges and names the next one due. Add commitment opens the form with that person chosen; Show all lists every commitment for them.
Why it exists
A household pays for more than one person, from more than one account. A cook's salary, a parent's insurance and a child's school fees each belong to someone. Naming the person and the account shows who each payment is for and where it is paid from.
Questions
What happens to commitments when a member is deleted?+
They stay, without a member. Before the delete, longbook states how many commitments, one-time charges and accounts name that person. Their accounts stay too, and belong to no one in particular. Deleting an account leaves its commitments in place the same way.
Can a bank statement add members?+
Yes. A statement import offers the people it names as members to tick, and files its lines under the account the statement is from. More on Import your bank statements.
Does a member need a longbook account?+
No. A member is a name in your records, not a sign-in. To show someone a month, share a report as a link.
