## Size-Run Calculator

                    Ordering clothing? Don’t buy the same number of every size.

                    actual shoppers buy them.

## Freight-to-Margin Alarm

                    Freight quietly eats margin. Enter your invoice and shipping
                    cost — see freight as a % of landed cost, effective margin,
                    and whether retail needs a bump.

SQ

## Store Capacity Calculator

                    Every square foot has an inventory number. Enter your footprint
                    and the Watermark tells you whether you’re over-stocked,
                    under-stocked, or right in the pocket.

### Built for the shop floor

                These tools are designed to be fast and simple — use them
                on your phone, at market, or behind the counter.
                No logins, no signups, no ads. Just the math you need.

### Found these handy?

                The tools stay free and signup-free. But if you want a little more
                where this came from, I send one short Retail Tidbit a couple times
                a week — real talk for independent shops, no fluff, no spam.
