                     Credit limit is the maximum negative balance that can be reached before the customer
                      is charged or treated as a debtor.

                    Understanding Credit Limit
                    In Parallels H-Sphere credit limit serves two purposes: 
                      - cumulative: This is applicable only to credit cards.  All setup, recurrent
                        and usage fees are accrued until their cumulative amount reaches or exceeds the
                        credit limit.  Only then is this amount charged.  This approach minimizes referrals
                        to credit card processing centers. 
                      - restrictive: This is pertinent to check payments and invalid/expired
                        credit cards.  When the negative balance exceeds the credit limit,
                        the account owner is considered to run into debts and is
                        blocked from buying any resources, paid or free.  Except for this, the functionality
                        of the debtor's account isn't affected, unless you configure the system to
                        suspend debtors.
                        Recurrent and usage fees will be still accrued, and the
                        debt will grow with every new billing period. 
                    Example: If you set the credit limit to $10, a user with
                      a $0 balance purchasing $5 resource won't be charged, even though
                      his balance will become -$5.  This is also true of invalid credit
                      card or check payments. 
                    Further, if this user decides to buy another $10 worth of resources,
                      he will get charged $15, and his balance will become
                      zero. But in case of an invalid credit card or a check payment,
                      this user won't be able to buy these extra $10 of resources,
                      and his balance will remain -$5. If this is the case, and if his
                      usage fee equals $20, at the end of the payment interval his debt
                      will increase to ( $5 + $ 20 = ) $25. 
                     
                    Setting Credit Limit in a Plan
                    To set plan's default credit limit:
                      
                      - Launch plan edit wizard
 
                      - On the first step at the bottom of the form you'll find the Credit Limit entry.
 
                      * If you leave the field empty, credit limit is set to 0. This results in immediate credit card account charges
                      and doesn't allow check paid accounts acquire resources with no money on their balance.
                      
                    Plan's default credit limit is the same for all accounts in this plan.
                    However, you can increase or reduce credit limit for particular accounts by following the instruction below. 
                      
                    Increasing Credit Limit for Individual Accounts
                    To increase or reduce credit limit for a particular account by a fixed amount: 
                    
                      - Find the account using the Search utility.
 
                      - Click the credit limit value in the Credit column.
 
                      - On the page that appears, enter the amount above plan's credit limit value.
                        For example, the Credit Limit for the plan is $10. To make it $12 for a specific account, enter 2.
 
                      - Click Increase.  The search results page will now show the difference from the default,
                        not the absolute credit limit.
 
                     
                      
                    Resetting Credit Limit For All Users
                    Sometimes you need to reset credit limit for all accounts to the plan's default value.
                      To do it in one go, do the following: 
                    
                      - Select Other in the E. Manager menu.
 
                      - Click Reset Credit Limit to eliminate credit limit increases in
                        your customers' accounts.
 
                     
                    Note: Remember that resetting credit limit for all accounts will set all increased
                      credit limits, if any, to the plan defaults. They will show as zero
                      on the Search result page in the Credit Limit section, where zero is the difference
                      from the default plan value.
