GS Uploader is a versatile app designed to streamline the process of uploading and purchasing custom printed materials. This app empowers merchants by allowing their customers to easily upload multiple image files, with an intuitive drag-and-drop feature for added convenience. The app's smart functionality automatically calculates the cost based on predefined rates set in the app's settings, simplifying the checkout process. Merchants can choose to measure in square or linear feet, with customizable units in inches or centimeters, catering to a variety of requirements. Once orders are placed, merchants have access to a separate listing for each order, with the ability to download all user-submitted files in a convenient zip format. This tool is ideal for businesses involved in producing stickers, direct to film (DTF) prints, sublimation, UV DTF, and more. Additional features include customization options for maximum width and rate settings, as well as automatic price calculations based on image dimensions and a check on image DPI, ensuring quality and accuracy throughout the printing process.
