Printing a Bill
You cannot print a bill more than once, unless you must give a copy of the bill to the customer.
You must use only a certified sales recording system (SRS) to print a copy, duplicate or any type of partial or total reproduction of the bill.
You cannot give the customer another document showing the total sale price and the taxes payable for a trip, except in certain special cases.
For example, if a customer asks for supporting documents for input tax credits (ITCs) and input tax refunds (ITRs), you can give the customer a supplementary document in addition to the bill produced using a certified SRS. The document must contain a reference to the bill.
You can also give the customer a weekly account statement or an estimate if it shows payment of all or part of the consideration for a supply before the bill containing all prescribed information is given to the customer.
