Know which promotions actually make you money.
Your last sale lifted revenue. Did it lift profit? Liftelia separates true uplift from customers who would have bought anyway, the dip after the sale ends, and sales stolen from your own products.
Revenue spikes hide where the margin went.
A promotion report usually shows extra revenue. The real question is how much extra gross profit was left after three hidden costs.
Customers who would have bought anyway
You gave the discount to people already planning to buy at full price. That margin was simply given away.
The dip after the sale
Part of the spike is demand pulled forward. Sales fall below normal in the weeks after, and that loss never shows in the promo report.
Cannibalization
Shoppers swap a full-price product for the discounted one. The promoted item wins, the category loses.
One illustrative promotion, 25% off
From profit on extra sales to net extra gross profit (USD, example figures)
From order export to a clear decision.
No consultants, no spreadsheets to maintain. Start with a CSV, move to the Shopify app when you want it on autopilot.
Share your order history
Export orders from Shopify, or connect the app with read-only access. 12 to 24 months of history works best. No customer names or emails needed.
We rebuild what would have sold
A statistical baseline for every product, adjusted for seasonality, holidays, trend and overlapping promotions. The gap between baseline and actual is the true uplift.
You get a verdict per promotion
Repeat, change the discount, or stop. Plus the discount level that looks best for each product and how much stock to prepare next time.
What the report looks like.
One row per promotion, with the profit effect after everything above is netted out.
| Promotion | Discount | Revenue lift | Incremental gross profit | Verdict |
|---|---|---|---|---|
| Spring collection, sitewide | 25% | +$48,000 | −$5,600 | Don't repeat |
| Serum bundle, 2 for 1 | 20% | +$31,200 | +$9,800 | Repeat |
| Summer clearance | 40% | +$22,500 | −$1,900 | Change to 25% |
| Loyalty code WELCOME15 | 15% | +$12,400 | +$3,100 | Repeat |
| Black Friday, top 20 SKUs | 30% | +$96,000 | +$14,300 | Change to 22% |
Example data for illustration. Real reports also show a confidence range for each result and flag promotions with too little data to call.
A different question from profit dashboards.
Profit analytics apps show what your margin was. Promotion simulators estimate what a future discount might do. Liftelia answers a third question: did your past promotions actually add profit?
