Want This Calculation in Real Time, Per SKU?

ProfitShield connects to Shopify and gives you a live margin per SKU, per channel, per day — using the same maths you just ran but with your actual order data. Real-time alerts when margin drops, COGS shifts, or your ad spend ratio crosses a threshold. Tuned for SMB pricing rather than DTC enterprise stacks.
