How to apply roundings.
We can apply different rounding methods in customer invoices. While creating customer invoices you can see a field named as ‘Cash Rounding Method’, here we can create and use cash rounding methods.
1. Add a rounding line
Create an invoice from Accounting module -> Customers -> Invoices.
Now, apply the previously created rounding method,
After that, choose the UP rounding method, then the total amount 100.22 will be changed to 100.30 ie, the total amount will be rounded up.
To see the difference, change the rounding method of the existing Cash Rounding Method as DOWN.
Then, check the invoice form.
The total amount will be rounded down from 100.22 to 100.20.
Now again, change the rounding method of Cash Rounding, and select HALF-UP method.
Again check the invoice form,
Here the unit price of the product is 100.22, so when you apply the HALF-UP rounding method, the total amount becomes 100.20 (ie, rounded down). If the same product having unit price 100.27 (ie, >100.25), then the total amount becomes 100.30 (ie, rounded up).
By analyzing the above example, you can see the total amount in invoice getting rounded based on the selected rounding method. This is a very common use case of any business industry. And most of the time, one couldn’t be able to provide the balance amount for decimal currency subunits. So the only possible solution here is the up rounding or down rounding.
2. Modify the tax amount
Create an invoice with a tax. For example, here GST 5% is used as tax.
Create a rounding with below details.
Now one can apply the created cash rounding method on the invoice,
After that, choose UP rounding method. Upon the action, the tax amount of 5.02 gets changed to 5.05 ie, the tax amount will be rounded up to the amount of the highest tax.
To see the difference, change the rounding method of the existing Cash Rounding Method as DOWN.
Then check in invoice form.
The tax amount will be rounded down from 5.02 to 4.95.
Now again change the rounding method of Cash Rounding Method, select HALF-UP method.
Again check the invoice form,
When applying the rounding method as HALF-UP, the tax amount becomes rounded up.
By analyzing the above example, you can see the tax amount in the invoice, rounded up to the amount of the highest tax based on the selected rounding method.
