Why we made these
A lot of running a shop comes down to a few sums: is this price still making money after the supplier's increase, can I afford to give this discount, how much do I need to sell to cover the rent. These tools answer those questions directly, and each page explains the working with an example, so you can do the same sum on paper when you need to.
Your numbers stay on your device
Every tool runs in your browser. Nothing you type is uploaded or stored on our servers. The only things remembered are your choice of currency and, if you ask the invoice generator to keep them, your shop's details for the next invoice, all held in your own browser's storage on that device.
Currencies
The tools default to Pakistani rupees and also work in Indian rupees, US dollars, euros, British pounds, UAE dirhams, Saudi riyals and Indonesian rupiah. The sums are the same in any currency; only the symbol changes.
