Increasing fields on products

Hi Infusionsoft Community.

I have recently purchased infusionsoft for my company Just Vehicle Solutions.

On our previous/current CRM we store a lot of information in our product pages. i.e as a vehicle leasing company, details of the vehicles.

Infusionsoft ‘products’ via the e-commerce platform only allows 3 standard fields but I need more creating.

What is the best way to do this? Do I need to find a partner company to help code these extra fields or?

Any help would be extremely appreciated as after today I’m a bit scared we have made the wrong decision!

What current shopping cart do yo use? There are various integrations out there.
