Alternative to google forms

Scenario

A person has to claim expenses he made, so he fills out these columns for multiple items
Item Name
Rate (in Rupees)
Quantity


After that all his items are displayed and he can seen Total amount. Then he submits the data

First I went to google forms but I couldn't find a way to enter multiple entries in same form.

Any other alternative ?
It has to be free, on the internet and easily accessible from mobile web
