prestashop invoice customization

We are using prestashop 1.6.0.9 with some Agile addons. We need to adapt credit to Italian fiscal Law. Credits are currently managed by “[url removed, login to view]” addon and are reported into the invoice document under the voice “payment method”.

For a correct utilization of credits from a fiscal point of view, is fundamental to modify the figures printed into the standard Prestashop invoice. Particularly, when in a payment process there is a credit (managed by Agile addon), the following figures must be modified:

- the total invoice amount must be deducted by credit amount (if total invoice amount is 100€ and credit is 20€ the total invoice amount must be changed into 80€);

- the VAT details must be recalculate consequently. The different VAT amount spread out into different percentages must be recomputed consequently to the credit reduction.

Generally we have 3 different situations:

- the credit is less than products price + taxes (in this case we have to re-compute total invoice amount and VAT details);

- the credit is equal to products price + taxes (in this case we have to re-compute total invoice amount and VAT details is equal to zero very easy);

- the credit is greater than products price + taxes (in this case we have to re-compute total invoice amount and VAT details is equal to zero very easy).

The rules to apply are the same rules currently applied for VOUCHER.
