Know if a discount makes money - before you run it.
ProfitShield works out the real profit behind every promotion from your own Shopify data - products, costs, orders and discounts - and flags the ones quietly losing you money. No customer data is collected, ever.
14-day free trial. Read-only access to your store - ProfitShield never changes your products, prices or discounts.

Illustrative example. In your store, every figure comes from your own data and carries the calculation behind it.
What it does
Three answers, from data you already have
ProfitShield syncs your catalogue, collections, discounts and the last 60 days of orders. Every screen answers one of three questions:
Every active discount is checked against your real costs - products underwater get flagged, not charted.
Each finding carries the dollars at stake at your current volume, with the calculation behind it.
A concrete fix per finding: cap the discount, exclude the losing products, or let it run.
Discount risk scanner
Find the discounts that sell below cost
ProfitShield checks every active discount against your product costs, shipping, payment fees and packaging. When a promotion pushes products under water, you get the money at stake and what to do about it - not a chart to interpret.
- Three rules: selling below cost, margin erosion, and discount stacking
- Rescanned daily, and immediately when a discount changes
- Every number opens into the inputs behind it

Promotion simulator
Test the discount before you publish it
Pick the whole store, a collection or specific products, set a discount, and read the break-even maths: the profit change at your current volume, the products that go below cost, and the headline number - how many more orders the promotion needs just to stand still.
- Break-even analysis works from day one, with no promotion history required
- Largest safe discount, calculated per selection
- Every simulation is stored with its inputs and formula version, so it still reproduces months later

Promotions
Every promotion, with the scope it actually has
A 25% discount on three collections is a different risk from 25% off everything. ProfitShield reads what each discount really applies to and shows it on the row - and when Shopify’s data cannot tell us the full entitlement, it says so instead of quietly assuming.
- Live, scheduled and finished promotions in one list
- A verdict per promotion at your current prices and costs
- Open one for its break-even maths and the products it puts below cost

more orders needed to break even - known before launch

Illustrative figures - in your store they come from your own data.

Straight answers
Do you see my customers’ data?
No - never. ProfitShield strips customer information before anything is stored. The app does not request Shopify’s customer scope at all, and order payloads are reduced to totals and line items before they reach our queue or database. Names, email addresses and postal addresses never arrive.
Where do the numbers come from?
From your Shopify store only: products and their cost per item, collections, discounts, and orders from the last 60 days. Nothing is estimated or generated. Where product costs are missing, those products are excluded from the maths and the app reports the coverage rather than guessing.
Do I have to change how I run discounts?
No. You keep creating discounts in Shopify. ProfitShield reads them, grades them and warns you - it never edits your products, prices, discounts or orders.
What happens when I uninstall?
Your store data is deleted within 48 hours of uninstall, and Shopify’s shop/redact request is honoured as a backstop so a missed notification cannot leave anything behind. Nothing is kept for analytics.

Install ProfitShield, let it sync, and read the first scan. It takes a few minutes and needs nothing from you but your store.
