Zoho Invoice - Calculate tax on rounded Price issue

Zoho Invoice - Calculate tax on rounded Price issue

I have product with price $60.00 including 10% tax. So, I set Tax = GST = 10% in settings.

What price should I have to pass to Create Invoice API to get invoice with Total amount $60?

If I pass $54.55 then Zoho calculate total price $60.01 and when I pass 54.54 then Zoho calculate total price $59.99, so I am not getting right invoice with total amount $60.00.

I found that Why Zoho calculate tax on rounded price instead of calculate tax on price and then round it?

Why there is not any option to pass price, tax amount, total amount instead of price and tax type only? all other invoice service providers provide this feature to pass price, tax, total fields to generate right invoice according to their needs.

I have to generate invoice in a week, can you help us to solve this problem?
