Free calculators for Gujarat's businesses
Drishvi Technology builds software for businesses that make, move and sell physical goods. These free tools come from the calculations we see every day: engineering and fabrication units in Rajkot working out metal weight before a purchase, ceramic and tile exporters in Morbi planning boxes and container loads, traders checking costs, and transporters estimating what a trip will really earn.
Every tool is free, needs no signup and runs entirely in your browser, so the numbers you enter stay private on your device. They are built mobile-first, which means you can open a link shared on WhatsApp and get an answer in seconds on the shop floor, at a dealer's counter or on the highway. New tools are added based on what businesses ask for — if you need one, suggest it.
