# Simple formula: (Total or SubTotal / 100 * Charge)
  wrong way to Paypal payment...
  
  Customer total: 100
  Paypal commission: 3.4%
  
  Now the customer will pay with paypal: 103.40
  When Paypal get the commission (103.40 - 3.4%) we have: 99.8844

# Complex Formula: (Total or SubTotal * PercentCharge) / (1- PercentCharge)
  right way to Paypal payment...
  
  Customer total: 100
  Paypal commission: 3.4%
  (100 * 0.034) / (1 - 0.034) = 3,5196 (rounded = 3.52)
  
  Now the customer will pay with paypal: 103.52
  When Paypal get the commission (103.52 - 3.4%) we have: 100.00

# Percentage charge support for shipping cost:
  If you declare percentage charge, you can also add this on shipping cost.
  Example with charge of 5% supplement, with shipping cost support:
  
             Sub-Total: 100.00
         Shipping Cost:  10.00
  Cash on Delivery(5%):   5.50
                 Total: 115.50

  (5% of sub-total) + (5% of shipping sost) == (5.00 + 0.50)
  
      Sub-Total: 100.00 + 5% (100.00 + 5.00 = 105.00)
  Shipping Cost:  10.00 + 5% ( 10.00 + 0.50 =  10.50)

==

# Enable/Disable fix based in total or sub-total of cart customer:
  If total or sub-total is lower and/or higher, to XXX; apply a load and/or discount, in fixed values or percentage of YYY
  A few example:
  - Line 1: Discount of 3% for Bank Transfer with order lower than to 150.00
  - Line 2: Discount of 5% for Bank Transfer with order higher than y ...
  or
  - Line 1: Cash on delivery Supplement/cost 5.00, for order lower than to XXX
  - Line 2: ..........

#Limited configuration for same payment methods with Sub-Total enabled:
  - apply to semi-pro (version)
  
  By configuring the same method of payment with more fixes, for example,
  
    line fix 1: cash on delivery with sub-total major of 100 and charge 10 (description: cash on delivery for order higher to 100)
    line fix 2: cash on delivery with sub-total major of 200 and charge 5  (description: cash on delivery for order higher to 200)
    line fix 3: ...
   
  the fix will be totaled and checkout will be in all...
                                1 x product yyy $ 10,00
                                     sub-total: $ 10,00
      cash on delivery for order higher to 100: $ 10,00
      cash on delivery for order higher to 200: $  5,00
                                         Total: $ 35,00
                                    
   So in this case the fix must be set:
     line1: cash on delivery with sub-total minor of 100.00 and charge 10 (description: cash on delivery for order lower than 100)
     line2: cash on delivery with sub-total major of 100.01 and charge 5  (description: cash on delivery for order higher to 100)

==

#Unlimited configuration for same payment methods with Sub-Total Enabled without sum of fix Eg:
  - apply to professional version
  
  line 1: payment-method-1 if sub-total is major(or equal) of 10 : discount of 3%
  line 2: payment-method-1 if sub-total is major(or equal) of 20 : discount of 5%
  line 3: payment-method-1 if sub-total is major(or equal) of 30 : discount of 7%
  line 4: payment-method-1 ....
  
  If you have the same payment method with different charges, set it in increasing order Eg:
    Bank Transfer Method with sub-total major(or equal) of 100 with (charge or)discount %-1
    Bank Transfer Method with sub-total major(or equal) of 300 with (charge or)discount %-3
    Bank Transfer Method with sub-total major(or equal) of 900 with (charge or)discount %-5
