PHP Script Feedback, Advice? (see demo)

Hi there,

I’ll appreciate any advice/opinions about my script.

The script is a marketplace of car parts and accessories. It’s integrated with the PayPal REST API, has a SaaS style plan/pricing (recurring plans, feature limits, etc - demo). The script comes with Geographical data (countries, regions, cities, etc), vehicle makes, models, years, part/accessory category, listing conditions (new, used, refurbished etc). It supports multi language (I’ve included English and Spanish out of the box). Payment methods can be added easily in the future. Listing images can be stored locally or using a dedicated services like Amazon S3.

It was built using Laravel 5.2.

Took 4-5 months to complete.
