  57
  58 C4::Accounts - Functions for dealing with Koha accounts
  59
  60 =head1 SYNOPSIS
  61
  62 use C4::Accounts;
  63
  64 =head1 DESCRIPTION
  65
  66 The functions in this module deal with the monetary aspect of Koha,
  67 including looking up and modifying the amount of money owed by a
  68 patron.
  69
  70 =head1 FUNCTIONS
  71
  72 =head2 recordpayment
  73
  74   &recordpayment($borrowernumber, $payment, $sip_paytype, $note);
  75
  76 Record payment by a patron. C<$borrowernumber> is the patron's
  77 borrower number. C<$payment> is a floating-point number, giving the
  78 amount that was paid. C<$sip_paytype> is an optional flag to indicate this
  79 payment was made over a SIP2 interface, rather than the staff client. The
  80 value passed is the SIP2 payment type value (message 37, characters 21-22)
  81
  82 Amounts owed are paid off oldest first. That is, if the patron has a
  83 $1 fine from Feb. 1, another $1 fine from Mar. 1, and makes a payment
  84 of $1.50, then the oldest fine will be paid off in full, and $0.50
  85 will be credited to the next one.
