Calculators

Store math without the finance-bro fog machine.

Run margin, discount, and free-shipping math with plain-English warnings when the numbers are quietly trying to mug you.

Hero tool

Upload a Shopify product CSV and catch duplicate SKUs, variant weirdness, missing prices, image gaps, SEO fields, and cleanup issues before import.

Margin math

See what a product actually keeps after COGS, shipping, packaging, fees, discounts, returns, ads, and other per-order costs.

Promo sanity check

Find out whether a discount creates profit, or just busier losses wearing a coupon hat.

Shipping math

Set a free shipping threshold that protects margin instead of quietly setting money on fire.
