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

 138

 140
 141 Records the fact that a patron has paid off the entire amount he or
 142 she owes.
 143
 144 C<$borrowernumber> is the patron's borrower number. C<$acctnumber> is
 145 the account that was credited. C<$amount> is the amount paid (this is
 146 only used to record the payment. It is assumed to be equal to the
 147 amount owed). C<$branchcode> is the code of the branch where payment
 148 was made.
