Launch Guard checks your Shopify store before the biggest weekend of the year: discounts that sell below cost, best sellers that run out on day one, rollouts still sitting in draft. Every issue comes with the fix.
Live demo · pick a store
Each demo store sells in a category that peaks over Black Friday and Cyber Monday, and each one has a different way to lose money. Pick one, scan it, then fix it.
What shoppers see on Friday. Pins mark what Launch Guard found; tap one to open the issue.
Why BFCM breaks stores
Nothing crashes. Orders keep coming. You find out on Monday, in the margin report.
A 40% code on a product with a thin margin sells every unit at a loss. Stack a second discount and more products follow.
Demand jumps several times over during BFCM. Stock that looks fine on a normal day runs out while the ads are still spending.
A rollout left in draft doesn't launch on its own. A discount set to midnight UTC starts at 7 PM the night before.
What it checks
Every check is read-only. Critical issues take 15 points off the score, warnings 5 and notes 1.
What each code does to margin.
Prices that are wrong before any sale.
Stock against the demand you expect.
Campaigns that won't launch as planned.
Examples
Check results from the four demo stores. Each issue comes with the fix and, on Pro, the money at risk.
| Issue | Example | Fix |
|---|---|---|
| Discount sells below costCritical | Code DOOR40 takes Studio Over-Ear headphones from $249 to $149, under their $158 cost. | Lower the discount to 25%, or exclude the product. |
| Discounts stack below costCritical | GLOW25 and VIP15 combine: Gold Sculpt Roller sells at $31 against a $32 cost. | Stop one discount from combining, or split their dates. |
| Best seller sells outCritical | Cloud Knit Crew has 4 in stock against about 36 expected sales over 4 days at 3× demand. | Restock about 32 units, or cap the item in the promotion. |
| Already oversoldCritical | Velvet Lip shows −6 in stock with “continue selling” on. | Turn off continue selling unless it's made to order. |
| Free by mistakeCritical | A bath bomb meant as a gift is an active product at $0. | Set the price, or unpublish the gift product. |
| Priced below costCritical | An espresso machine lists at $499 after its cost rose to $540. | Raise the price or correct the cost per item. |
| Rollout still in draftCritical | The “Doorbusters” rollout is due Friday 12:00 AM but is still a draft. | Schedule the rollout. |
| Time zone slipWarning | GLOW25 ends at midnight UTC, which is 7:00 PM the evening before in New York. | Set start and end times in the store's time zone. |
| Code with no usage limitWarning | DOOR40 (40% off) has no total limit and no once-per-customer rule. | Set a usage limit or one use per customer. |

FAQ
No. It only reads. Each issue links to the exact product, discount or rollout so you make the change. The fix buttons on this page change demo data only.
For a discount below cost: the loss per unit × the units you expect to sell (30-day daily sales × expected demand × campaign days). For stock that runs out: the units you'd be short, valued at the sale price.
Shopify rollouts schedule a campaign's discounts, prices and theme changes to go live together. Launch Guard checks that each rollout will launch, ends on time and doesn't switch on a discount that loses money.
A week before the sale, again after every campaign change, and the morning it starts. Pro does the last two for you.
No. VOLTA, LUMÈRE, NORTHWARD and HEARTH & HAUS are fictional brands made for this demo. Product photos come from Burst by Shopify; prices, costs and sales are demo data.
