TisFile is a SaaS platform that lets merchants offer 3D product customization on their websites. Customers upload logos, position and transform them on 3D models in a real-time interactive viewer, then generate ready-to-print engraved files. Merchants manage products, viewers, quotes, and billing through a dashboard. The viewer can be embedded on any website via iframe. Tiered subscription plans control usage limits like quotes per month, number of products, viewers, and streaming quality.
