46 C4::Accounts - Functions for dealing with Koha accounts
48 =head1 SYNOPSIS
50 use C4::Accounts;
52 =head1 DESCRIPTION
54 The functions in this module deal with the monetary aspect of Koha,
55 including looking up and modifying the amount of money owed by a
56 patron.
58 =head1 FUNCTIONS
60 =head2 recordpayment
62 &recordpayment($borrowernumber, $payment);
64 Record payment by a patron. C<$borrowernumber> is the patron's
65 borrower number. C<$payment> is a floating-point number, giving the
66 amount that was paid.
68 Amounts owed are paid off oldest first. That is, if the patron has a
69 $1 fine from Feb. 1, another $1 fine from Mar. 1, and makes a payment
70 of $1.50, then the oldest fine will be paid off in full, and $0.50
71 will be credited to the next one.

140 Records the fact that a patron has paid off the entire amount he or
141 she owes.
143 C<$borrowernumber> is the patron's borrower number. C<$acctnumber> is
144 the account that was credited. C<$amount> is the amount paid (this is

146 amount owed). C<$branchcode> is the code of the branch where payment
147 was made.
