There are two ways of calculating totals when it comes to invoicing.

Method 1: the sum of rounded values

Method 2: the sum of values, rounded

**Zervant uses the Method 1**. See below:

**Method 1: Sum of rounded lines**

For example, the sum of each line is 5.764, which is then rounded to 5.76 (2 d.p.). As such, the total of the invoice using method 1 is:

5.76 + 5.76 = 11.52

*(Method 2: Sum of lines, rounded*

*5.764 + 5.764 = 11.528*

*Rounded to 11.53)*
