  56 C4::Accounts - Functions for dealing with Koha accounts
  57
  58 =head1 SYNOPSIS
  59
  60 use C4::Accounts;
  61
  62 =head1 DESCRIPTION
  63
  64 The functions in this module deal with the monetary aspect of Koha,
  65 including looking up and modifying the amount of money owed by a
  66 patron.
  67
  68 =head1 FUNCTIONS
  69
  70 =head2 makepayment
  71
  72   &makepayment($accountlines_id, $borrowernumber, $acctnumber, $amount, $branchcode);
  73
  74 Records the fact that a patron has paid off the entire amount he or
  75 she owes.
  76
  77 C<$borrowernumber> is the patron's borrower number. C<$acctnumber> is
  78 the account that was credited. C<$amount> is the amount paid (this is
  79 only used to record the payment. It is assumed to be equal to the
  80 amount owed). C<$branchcode> is the code of the branch where payment
  81 was made.

 100 borrower number.
