*In some countries, calculations must always be done using method 1 for generating invoices. As this is the default calculation rule for Dolibarr and recommended in most countries nowdays, there is nothing to change from the default configuration..

*In few countries (rarely), calculations must always be done using method 2 for generating invoices. To avoid having the total shown at the top of the invoice that differs from the totals of detailed lines, just do not show column I on invoice. This is the case with Dolibarr default invoice templates, so that's not a problem. To enable this rule of calculation, you must use Dolibarr version 3.5+ and add/override the constant MAIN_ROUNDOFTOTAL_NOT_TOTALOFROUND to 1 (in Home - Setup - Other). It seems there is no more example of countries in the world today that need this.

*In some countries, both methods are still possible. In this case just use method 1 that will be more accurate for accounting (since if you use method 2, the total of vat collected on your invoice will not be the sum of F, nor the sum of G and this will create confusion subsequently). If you prefer to use method 2 (a very bad idea), use Dolibarr version 3.5+ and set constant MAIN_ROUNDOFTOTAL_NOT_TOTALOFROUND to 1 (Home - Setup - Other).
