Additional product price fields and calculation on invoice

[Tomin]

Hi,

 

Trying to figure out is it possible use PS 1.5 as rental/reservation web page.

 

So, we have Product A with rental price 1eur per day and used price with VAT field.

When we rent product's, we are taking deposit and for Product A we would like to have 30eur deposit, which are given back after product A is returned to us undamaged. If we give 2 pieces for 2 days, rental would be 4eur with 60eur deposit

 

I need additional deposit price field on product BO page, so I can add 30eur, it would be shown on product FO page.

 

I need deposit amount calculated and showed on invoice as well as:

 

default PS invoice: rental PRODUCT A 2 day's / 1eur piece / 2 pieces ordered / TOTAL 4eur

 

additional invoice field(s) - PRODUCT A, deposit value x pieces = 60eur

 

 

Some advice and solution?

 

 

I know about 2 expensive modules available and only one of them is really usable, so may be some community solution?

 

Thanks.
