The difference between the total amount of the travel service all-electric invoice voucher and the amount of this deduction lies in their different meanings.

The total amount of the all-electric invoice voucher for travel services refers to the total amount of all travel service items issued by the invoice, including taxes. The amount of this deduction refers to the amount of tax that can be deducted from the invoice, that is to say, this amount can be deducted from the tax payable by the taxpayer. This amount is usually calculated by the buyer based on his/her tax situation.

In actual operation, the purchaser needs to calculate the amount of this deduction based on its own tax situation, and make corresponding deductions when declaring taxes.
